JP7554214B2 - Entrance/exit management system and modular house - Google Patents

Description

Application of Article 30, Paragraph 2 of the Patent Act Publication date: July 17, 2020, Publication location: Construction site of "Senju the Tower" (Senju 1-chome, Adachi-ku, Tokyo), Publisher: Fujita Corporation, Content of disclosed invention: Fujita Corporation installed and used the entrance/exit management system and unit house invented by Chiba Takushi, Yamaguchi Hitomi, and Mori Taiki at the construction site of the newly constructed apartment building "Senju the Tower" at 1-100 Senju, Adachi-ku, Tokyo (land number).

One embodiment of the present invention relates to an entrance/exit management system that manages people entering and leaving. Another embodiment of the present invention relates to a unit panel or unit house equipped with an entrance/exit management system.

Conventionally, there has been known a method of managing entry for visitors using a so-called walk-through face authentication system that photographs a person walking and performs face authentication on that person (see, for example, Patent Document 1). A walk-through face authentication system completes the authentication process before a walking person (visitor) reaches the entrance gate, and can determine whether or not to permit entry to the visitor. For this reason, a walk-through face authentication system places less of a burden on visitors and can be said to be highly convenient.

In recent years, there have been an increasing number of cases where people's body temperatures are measured and entry is controlled to prevent the spread of infectious diseases such as influenza viruses and coronaviruses. For example, Patent Document 2 describes an authentication device that performs personal authentication and temperature measurement of visitors.

JP 2015-1790 A JP 2012-219539 A

When installing an authentication device in a location where work is only carried out during a specific construction period, such as a construction site, it is necessary not only to install the authentication device, but also to remove it after the construction period ends. In other words, since the authentication device needs to be installed and removed for each construction site, the authentication device must be easy to install and remove. Furthermore, if authentication takes a long time, there is a possibility that delays will occur in the construction period.

Furthermore, if a worker at a construction site is later found to have been infected with the influenza virus or coronavirus, it may be necessary to trace the worker's past actions. In such cases, it is often necessary to identify not only the actions of the infected worker, but also other workers who worked with him or her.

Therefore, there was a demand for an entrance/exit management system at construction sites that could be easily installed and could manage not only entry but also exit.

In view of the above problems, one embodiment of the present invention aims to provide an entrance/exit management system that manages entry and exit. Another embodiment of the present invention aims to provide a unit panel or unit house equipped with an entrance/exit system that is easy to install.

First Embodiment
An entrance/exit management system 10 according to one embodiment of the present invention will be described with reference to FIGS.

[1. Configuration of the entrance/exit management system 10]
FIG. 1 is a layout diagram of an entrance/exit management system 10 according to an embodiment of the present invention. The entrance/exit management system 10 is installed and used in a passage 120 connecting a first gate 100 and a second gate 110 facing the first gate 100. A construction site is located beyond the second gate 110, and a target person (worker) can enter the construction site by passing through the second gate 110. That is, the entrance/exit management system 10 can be installed at the entrance/exit of the construction site. Although the layout of the entrance/exit management system 10 is the same in FIG. 1(A) and FIG. 1(B), the figures respectively show the time of entry and exit of a target person. When a target person enters a construction site, the target person enters through the first gate 100, undergoes an entrance process using the entrance/exit management system 10, and exits through the second gate 110. In contrast, when the subject leaves the construction site, the subject enters through the second gate 110, is processed for exit using the entrance/exit management system 10, and leaves through the first gate 100. Therefore, entrance/exit management (entry processing and exit processing) is performed for the subject not only when he/she enters the construction site but also when he/she leaves using the entrance/exit management system 10.

Note that while FIG. 1 shows a first gate 100 and a second gate 110, the first gate 100 and the second gate do not have to be clearly installed. For example, the entrance/exit management system 10 may be installed in the middle of the passage 120, with one end of the passage 120 where the entrance/exit management system 10 is installed being the first gate 100 and the other end being the second gate 110. Even in this case, the entrance/exit management system 10 is used when the subject passes through the passage 120, so that the subject's entrance/exit management can be performed.

As shown in FIG. 1(A) and FIG. 1(B), the entrance/exit management system 10 includes a first information processing device 200, a first imaging device 210, a first display device 220, a warning device 230, a second information processing device 300, a second imaging device 310, a second display device 320, and a third information processing device 400. The first information processing device 200, the first imaging device 210, the first display device 220, and the warning device 230 are used in the entrance process of the subject. The second information processing device 300, the second imaging device 310, and the second display device 320 are used in the exit process of the subject. The third information processing device 400 is used in the entrance/exit management process of the subject.

Although not shown in detail, the first imaging device 210, the first display device 220, and the warning device 230 are connected to the first information processing device 200. The second imaging device 310 and the second display device 320 are connected to the second information processing device 300. The first information processing device 200 and the second information processing device 300 are connected to the third information processing device 400. These connections may be wired or wireless. For example, any or all of the first information processing device 200, the second information processing device 300, and the third information processing device 400 may be connected via a network without being installed at the construction site. Also, some of the components included in each of the first information processing device 200, the second information processing device 300, and the third information processing device 400, which will be described later, may be connected via a network.

The first imaging device 210, the first display device 220, and the warning device 230 are arranged near the second gate 110. The first imaging device 210 is arranged, for example, on the ceiling surface or wall surface of the passage 120. The first imaging device 210 can photograph a subject who enters from the first gate 100 and passes through the passage 120. The first imaging device 210 can photograph a walking subject, and the subject does not necessarily have to stop in front of the first imaging device 210. The first information processing device 200 can match the photographed subject or determine the subject's temperature (body temperature). The first information processing device 200 may be installed inside the passage 120 or may be arranged outside the passage 120. The first display device 220 can display the matching result of the subject. The subject can check the matching result displayed on the screen of the first display device 220 and exit from the second gate 110. The warning device 230 is activated when the subject's temperature exceeds a predetermined temperature (threshold value) and notifies the subject that an abnormality in body temperature has been detected.

Similarly, the second imaging device 310 and the second display device 320 are arranged near the first gate 100. The second imaging device 310 arranged on the ceiling or wall of the passage 120 can capture an image of a subject who enters through the second gate 110 and passes through the passage 120. The second information processing device 300 arranged inside or outside the passage 120 can compare the image of the subject. The subject can check the comparison result displayed on the screen of the second display device 320 and exit through the first gate 100.

The entrance/exit management system 10 measures the subject's body temperature when the subject enters the construction site, but does not measure the subject's body temperature when the subject leaves the construction site. However, the entrance/exit management system 10 may be configured to measure the subject's body temperature when the subject leaves the construction site. In that case, the entrance/exit management system 10 may use a warning device to notify when it detects a change in the subject's body temperature that is greater than a set difference compared to when the subject entered the construction site.

The above-mentioned device layout is just an example, and the layout of the devices in the entrance/exit management system 10 according to this embodiment is not limited to this. Some modified examples of the layout of the entrance/exit management system 10 will be described later.

The configuration of each device in the entrance/exit management system 10 is explained below.

Each of the first information processing device 200, the second information processing device 300, and the third information processing device 400 is a computer capable of executing arithmetic processing based on a program. The computer includes, for example, a central processing unit (CPU) as an arithmetic means and a storage device as a storage means. The storage device is, for example, a random access memory (RAM), a read only memory (ROM), or a hard disk drive (HDD). The first information processing device 200, the second information processing device 300, and the third information processing device 400 may be one computer, or may be multiple computers each capable of processing. In addition, each of the first information processing device 200, the second information processing device 300, and the third information processing device 400 may be multiple computers (servers), and multiple computers may be connected via a network.

Each of the first imaging device 210 and the second imaging device 310 is a camera capable of capturing an image of a subject. The camera includes, for example, a solid-state imaging element such as a CCD (Charge-Coupled Device) image sensor or a CMOS (Complementary MOS) image sensor. The first imaging device 210 is a camera capable of capturing images in the infrared light region as well as images in the visible light region. The first imaging device 210 may capture images in the visible light region and the infrared light region with one camera, or may include two cameras, one of which captures images in the visible light region and the other of which captures images in the infrared light region. From the captured image in the infrared light region, the temperature distribution of a subject or object contained in the image can be obtained. In addition, when the first imaging device 210 includes two cameras, it is preferable that the two cameras are arranged so that the positions in the visible light region image and the positions in the infrared light region image correspond to each other. The second imaging device 310 may be a camera similar to the first imaging device 210, and may be a camera that captures only the visible light range.

Each of the first display device 220 and the second display device 320 is a device capable of displaying images, and is, for example, a liquid crystal display device or an OLED (Organic Light-Emitting Diode) display device. Each of the first display device 220 and the second display device 320 preferably includes an input device, and may include, for example, a touch panel that allows operation by touching the display on the screen.

The warning device 230 is a device that can notify a target person that an abnormality has occurred, and is, for example, a warning light or a speaker that emits a warning sound. The warning device 230 may also be an electronic bulletin board.

Below, the configuration of each device in the entrance/exit management system 10 will be explained in more detail with reference to Figures 2 and 3.

Figures 2 and 3 are block diagrams showing the configuration of an entrance/exit management system 10 according to one embodiment of the present invention.

As shown in FIG. 2, the entrance/exit management system 10 includes a first imaging unit 1010, a first face information generation unit 1020, a temperature information generation unit 1030, a registration information storage unit 1040, a first face matching unit 1050, an entrance person information processing unit 1060, a first display unit 1070, a warning unit 1080, a second imaging unit 1090, a second face information generation unit 1100, a second face matching unit 1110, an exit person information processing unit 1120, a second display unit 1130, an entrance/exit management information processing unit 1140, and an entrance/exit management information storage unit 1150.

As shown in FIG. 3, the first information processing device 200 includes a first face information generation unit 1020, a temperature information generation unit 1030, a first face matching unit 1050, a registration information storage unit 1040, and an entrance person information processing unit 1060. The first imaging device 210 includes a first imaging unit 1010. The first display device 220 includes a first display unit 1070. The warning device 230 includes a warning unit 1080. The second information processing device 300 includes a second face information generation unit 1100, a second face matching unit 1110, a registration information storage unit 1040, and an exit person information processing unit 1120. The second imaging device 310 includes a second imaging unit 1090. The second display device 320 includes a second display unit 1130. The third information processing device 400 includes an entrance/exit management information processing unit 1140 and an entrance/exit management information storage unit 1150.

The configuration of each device is not limited to that shown in FIG. 3. For example, the first imaging device 210 may include a first imaging unit 1010, a first face information generation unit 1020, and a temperature information generation unit 1030, and the first information processing device 200 may include a first face matching unit 1050 and an attendee information processing unit 1060.

The first imaging unit 1010 can capture an image in the visible light region that includes the subject and generate image data. The first imaging unit 1010 can also capture an image in the infrared light region that includes the subject and generate temperature distribution data. The image data and temperature distribution data are transmitted to the first face information generation unit 1020 and the temperature information generation unit 1030, respectively.

The first face information generation unit 1020 can receive image data and detect the face area of the subject from the image data. The first face information generation unit 1020 can also generate face image data including the face area detected from the image data, and generate face information including the face image data and position information of the face image data in the image data. All or a part of the face information is transmitted to the temperature information generation unit 1030, the first face matching unit 1050, and the visitor information processing unit 1060.

Here, we will explain the facial image data generation process executed by the first facial information generation unit 1020.

The first face information generating unit 1020 can detect feature points such as the eyes, nose, and mouth, which are parts that make up a face, from the image data, and detect a face area from the relative positions of these feature points. The first face information generating unit 1020 can also perform edge processing on the image data, detect an elliptical edge distribution that approximates the outline of a person's head, and detect an area surrounded by the edge distribution as a face area. The first face information generating unit 1020 can also compare the image data with a pre-registered face shape model to calculate the similarity, and detect an area with a predetermined similarity or higher as a face area.

The first face information generating unit 1020 can generate rectangular face image data including the face area based on the size of the detected face area. However, in matching face image data, a resolution sufficient to detect feature points such as the eyes, nose, or mouth in more detail is required, so the first face information generating unit 1020 may execute a size (or resolution) determination process on the generated face image data. In the size determination process of the face image data, if the area of the face image data is within a predetermined range, it is determined to be appropriate face image data. Also, if each of the horizontal length and vertical length of the face image data is within a predetermined range, it may be determined to be appropriate face image data. Note that the face image data determined to be appropriate may be converted to a predetermined size to make it suitable for the matching process.

When the image data includes multiple people, the first face information generation unit 1020 may detect multiple face regions and generate multiple face image data. In this case, the first face information generation unit 1020 may select the face region of the foremost person from the multiple detected face regions and generate face image data including the face region of the foremost person. For example, the first face information generation unit 1020 may select the face region with the largest area as the face region of the foremost person and generate face image data.

The first face information generation unit 1020 can execute the above-mentioned processing and transmit face information including the generated face image data to the first face matching unit 1050. The first face information generation unit 1020 can also calculate position information of the face image data in the image data and transmit face information including the position information of the face image data to the temperature information generation unit 1030.

The temperature information generating unit 1030 receives the temperature distribution data and the face information, extracts the temperature at the position information of the face image data of the face information from the temperature distribution data, and can generate face temperature information. The temperature at the position information of the face image data corresponds to the temperature of the subject's face, i.e., the subject's body temperature. In other words, the temperature information includes information on the subject's body temperature. The temperature information is sent to the visitor information processing unit 1060.

The registration information storage unit 1040 can store information (registration information) of workers working at a construction site as a database. The registration information can be created in advance. The registration information includes, for example, facial image data, affiliation, or name of the worker, which are linked and stored.

The first face matching unit 1050 receives face information and acquires registration information from the registration information storage unit 1040, and can match the face image data of the face information with the face image data of the registration information. Furthermore, if the first face matching unit 1050 is able to match the subject through the matching process (if the similarity with at least one registered person is equal to or greater than a threshold value in the matching process), it transmits all or part of the registration information of the matched registered person to the visitor information processing unit 1060. In contrast, if the first face matching unit 1050 is unable to match the subject through the matching process (if the similarity with any registered person is less than a threshold value in the matching process), it generates match failure information and transmits the match failure information to the visitor information processing unit 1060.

Here, we will explain the face image data matching process performed by the first face matching unit 1050.

The first face matching unit 1050 can detect feature points such as the size, direction, or relative position of the eyes, nose, mouth, and other parts that make up a face from the image data. The first face matching unit 1050 can also detect the facial contour as a feature point. The first face matching unit 1050 compares the detected feature points with the feature points of the facial image data of the registration information in the database stored in the registration information storage unit 1040, and calculates the degree of similarity. The first face matching unit 1050 determines the registrant of the registration information with the highest degree of similarity as the target.

When the entrance/exit management system 10 is used at a construction site, a worker may be wearing a helmet and a mask. In particular, when a worker is wearing a mask, the nose and mouth are covered by the mask, so fewer feature points are detected. Therefore, the first face matching unit 1050 performs a process to determine whether a mask is being worn on the face image data, and if it is determined that a mask is being worn, it can also weight the eyes as a feature point with a higher priority and calculate the similarity.

The first face matching unit 1050 can execute the above-mentioned processing and transmit the registration information of the identified registered person to the visitor information processing unit 1060. Furthermore, if any of the calculated similarities are less than a threshold value, the first face matching unit 1050 can generate non-matching information and transmit the non-matching information to the visitor information processing unit 1060.

The visitor information processing unit 1060 can receive face information, temperature information, and registration information, and generate visitor information in which these are linked. The visitor information includes, for example, the entry date and time, face image data of the face information, temperature (body temperature) of the temperature information, or face image data, affiliation, or name of the registration information. In addition, when the visitor information processing unit 1060 receives unmatchable information, the visitor information processing unit 1060 can generate visitor information in which the face information, temperature information, and unmatchable information are linked. In this case, visitor information is generated that includes, for example, the entry date and time, face image data of the face information, or temperature of the temperature information, although the subject is not specified. The visitor information is transmitted to the entrance and exit management information processing unit 1140. In addition, the visitor information processing unit 1060 can convert the visitor information into a display image signal and transmit the display image signal to the first display unit 1070. In addition, when the temperature of the subject included in the temperature information exceeds a predetermined temperature, the visitor information processing unit 1060 can generate a control signal and transmit the control signal to the warning unit 1080.

The first display unit 1070 can receive a display image signal and display an image based on the display image signal on the screen. The first display unit 1070 can display, for example, face image data from the face information, temperature (body temperature) from the temperature information, or face image data, affiliation, or name from the registered information on the screen. The first display unit 1070 can also display, on the screen, an icon for checking whether the face information matches the registered information, for example, a touchable icon in the event of a false positive.

The warning unit 1080 can receive a control signal and activate the warning device 230 based on the control signal.

The second imaging unit 1090 has the same functions as the first imaging unit 1010. That is, the second imaging unit 1090 can capture an image in the visible light range that includes a subject and generate image data. The image data is transmitted to the second face information generation unit.

The second face information generation unit 1100 has the same functions as the first face information generation unit 1020. That is, the second face information generation unit 1100 can receive image data and detect the face area of the target person from the image data. The second face information generation unit 1100 can also generate face image data including the face area detected from the image data, and generate face information including the face image data and position information of the face image data in the image data. All or a part of the face information is transmitted to the second face matching unit 1110 and the exiting person information processing unit 1120.

The second face information generating unit 1100 can generate face image data in a similar manner to the first face information generating unit 1020. Therefore, a description of the face image data generation process executed by the second face information generating unit 1100 will be omitted here.

The second face matching unit 1110 has the same functions as the first face matching unit 1050. That is, the second face matching unit 1110 can receive face information, acquire registration information from the registration information storage unit 1040, and match the face image data of the face information with the face image data of the registration information. In addition, if the second face matching unit 1110 is able to match the subject through the matching process (if the similarity with at least one registered person is equal to or greater than a threshold in the matching process), it transmits all or part of the registered information of the matched registered person to the exiting person information processing unit 1120. In contrast, if the second face matching unit 1110 is unable to match the subject through the matching process (if the similarity with any registered person is less than a threshold in the matching process), it generates match failure information and transmits the match failure information to the exiting person information processing unit 1120.

The second face matching unit 1110 can match face image data in a manner similar to that of the first face matching unit 1050. Therefore, a description of the matching process of face image data executed by the second face matching unit 1110 will be omitted here.

The exit person information processing unit 1120 has the same functions as the entrance person information processing unit 1060. That is, the exit person information processing unit 1120 can receive face information and registration information and generate exit person information in which these are linked. The exit person information includes, for example, the exit date and time, face image data of the face information, or face image data, affiliation, or name of the registration information. In addition, when the exit person information processing unit 1120 receives unmatchable information, the exit person information processing unit 1120 can generate exit person information in which the face information and the unmatchable information are linked. In this case, the target person is not specified, but exit person information including, for example, the exit date and time and face image data of the face information is generated. The exit person information is transmitted to the entrance and exit management information processing unit 1140. In addition, the exit person information processing unit 1120 can convert the exit person information into a display image signal and transmit the display image signal to the second display unit 1130. Furthermore, when the exiting person information processing unit 1120 receives information indicating that matching is not possible, it can convert the facial image data of the facial information into a display image signal and transmit it to the second display unit 1130.

The second display unit 1130 has the same functions as the first display unit 1070. That is, the second display unit 1130 can receive a display image signal and display an image based on the display image signal on the screen. The second display unit 1130 can display, for example, face image data of the face information, or face image data, affiliation, or name of the registered information on the screen. The second display unit 1130 can also display, on the screen, an icon for checking whether the face information matches the registered information, for example, an icon that can be touched when the match is a false positive.

The entrance/exit management information processing unit 1140 can receive entrance information and exit information, and generate entrance/exit management information that links the two. In other words, the entrance/exit management information processing unit 1140 can identify the entrance information and exit information, respectively, and create databased entrance/exit management information with each of the entrance information and exit information as an item. The entrance/exit management information includes, for example, the entrance date/time, temperature, affiliation, or name of the entrance information, or the exit date/time, affiliation, or name of the exit information. The entrance/exit management information may also include facial image data of the facial information included in the entrance information, or facial image data of the facial information included in the exit information.

The entrance/exit management information storage unit 1150 can store the entrance/exit management information as a database.

The above-mentioned devices and the configuration of each device are merely examples, and the configuration of the entrance/exit management system 10 according to this embodiment is not limited to this. For example, if the transmission and reception of data or information by each component is wireless, each device may include a communication unit.

Furthermore, the use of the entrance/exit management system 10 is not limited to entrance/exit management at construction sites. For example, the entrance/exit management system 10 can be installed at the entrances and exits of an event facility or event venue to manage the entrance and exit of users. One example of installing the entrance/exit management system 10 at an event facility is when tickets are sold after users' facial image data is registered. In this case, users can enter and exit the event facility by walking through, and even if it is later discovered that one of the users is infected with the influenza virus or coronavirus, the entrance/exit management system 10 can be used to track the users.

Below, the entrance and exit processes of the entrance and exit management system 10 will be explained with reference to Figures 4 to 8.

2. Admission Processing of the Entrance/Exit Management System 10
4 to 7 are sequence diagrams of the entrance process in the entrance/exit management system 10 according to one embodiment of the present invention. Fig. 4 to Fig. 7 respectively show normal entrance process, entrance process when a false detection is made in matching the subject, entrance process when an abnormality in the subject's body temperature is detected, and entrance process when matching the subject cannot be made.

Referring to FIG. 4, a normal entrance process using the entrance/exit management system 10 will be described. The first imaging device 210 (first imaging unit 1010) captures an image of a subject walking through the passage 120, and generates image data and temperature distribution data (step S1000). The generated image data and temperature distribution data are transmitted to the first information processing device 200.

The first information processing device 200 (first face information generation unit 1020) detects a face area in the image data and generates face image data (step S1110). The first information processing device 200 (first face matching unit 1050) also matches the generated face image data with face image data of the registration information in the database to identify the target person (step S1120). The first information processing device 200 (attendee information processing unit 1060) also generates attendee information based on the registration information of the identified registrant (step S1130) and converts the attendee information into a display image signal. The converted display image signal is transmitted to the first display device 220.

The first display device 220 (first display unit 1070) displays an image based on the display image signal (an image corresponding to the result of the matching process) on the screen (step S1040). The subject confirms that the registered user information displayed on the screen is his/her own information, and then exits through the second gate 110. After a predetermined time has elapsed for the subject to confirm the display on the screen, the visitor information is transmitted to the third information processing device 400.

The third information processing device 400 (entrance/exit management information processing unit 1140) generates entrance/exit management information by converting the visitor information transmitted from the first information processing device 200 into a database, and stores the entrance/exit management information in the entrance/exit management information storage unit 1150 (step S1050).

Referring to FIG. 5, the entry process when the matching of the subject is a false positive will be described. Steps S1000 to S1040 are the same as the process described above, so some steps are omitted in FIG. 5. If the registration information displayed on the screen of the first display device 220 is not the subject's own information, the subject touches the first icon displayed on the screen of the first display device 220 to input that it is a false positive (step S1060). Operation information performed by the subject is transmitted to the first information processing device 200.

When the first information processing device 200 receives the operation information, it does not transmit visitor information to the third information processing device 400. Furthermore, steps S1100 to S1140 again photograph the subject, perform matching processing, and display the matching processing results. In this case, step S1100 may be started based on request information from the first information processing device 200. Note that steps S1100 to S1140 are similar to steps S1000 to S1040, so a description thereof will be omitted here.

With reference to Figure 6, the entry process when an abnormality in the subject's body temperature is detected will be described. Steps S1000 to S1040 are the same as the process described above, so some steps are omitted in Figure 6. The first information processing device 200 (entry person information processing unit 1060) generates a control signal if the temperature included in the temperature information (i.e., the subject's body temperature) is equal to or higher than a predetermined temperature (step S1070). The control signal is sent to the warning device 230.

The warning device 230 (warning unit 1080) can be operated based on a control signal. The subject can confirm that his or her own body temperature is high by the operation of the warning device 230. When the subject wishes to remeasure his or her body temperature, he or she can simply touch the first icon displayed on the screen of the first display device. This operation causes the subject's image to be photographed again, the matching process to be performed, and the results of the matching process to be displayed again, as described above, so that the subject's body temperature can be remeasured.

With reference to FIG. 7, the entry process when the target person cannot be matched will be described. Steps S1000 to S1020 are the same as the process described above, so the description will be omitted here. If the similarity with any registered person in the image data matching process is less than the threshold value, the first information processing device 200 (first face matching unit 1050) generates match impossible information (step S1090). The match impossible information is converted into a display image signal by the first information processing device 200 (entrant information processing unit 1060) and transmitted to the first display device 220. The match impossible information is also transmitted to the third information processing device 400.

3. Exit Processing of the Entrance/Exit Management System 10
8 is a sequence diagram of the exit process in the entrance/exit management system 10 according to one embodiment of the present invention. Steps S2000 to S2050 are similar to steps S1000 to S1050, so detailed explanations will be omitted here, but in the exit process, exiting person information is generated instead of entering person information.

The configuration and processing of the entrance/exit management system 10 have been explained above, but the entrance/exit management system 10 can manage not only the entry of subjects, but also their exit. In addition, the entrance/exit management system 10 can generate entrance/exit management information that stores information regarding the entry and exit of multiple subjects in a database. Therefore, by searching using the entrance/exit management information, it is easy to understand the duration of a subject's stay, etc.

<Modification 1>
A modified example of the layout of the entrance/exit management system 10 will be described with reference to FIG.

9 is a layout diagram of an entrance/exit management system 10 according to an embodiment of the present invention. Although the layout of the entrance/exit management system 10 is the same in FIG. 9(A) and FIG. 9(B), the entrance/exit management system 10 is shown at the time of entry and exit of the subject, respectively. As shown in FIG. 9(A) and FIG. 9(B), the second gate 110a is not provided opposite the first gate 100a. Specifically, the second gate 110a is provided on a side that is substantially perpendicular to the side on which the first gate 100a is provided. Therefore, when the subject moves from the first gate 100a to the second gate 110a, or when the subject moves from the second gate 110a to the first gate 100a, the subject needs to change direction in the middle of the passage 120a. Therefore, the subject is likely to check the front when changing direction, and the first imaging device 210 is likely to capture the subject's front face.

To manage the movement of the subject in the passage 120a (hereinafter sometimes referred to as "traffic flow"), a mark such as an arrow indicating the direction of travel may be provided on the floor or walls of the passage 120a to guide the subject. In addition, the traffic flow may be formed using part of the configuration of the entrance/exit management system 10. For example, as shown in Figures 9(A) and 9(B), a first information processing device 200, a second information processing device 300, and a third information processing device 400 may be placed at a position where the subject changes direction (at an L-shaped bend), so that the subject can move around these devices.

The movement line of this modified example includes curves, and the distance traveled by the subject can be longer than a simple straight line. In addition, in a straight line of movement, multiple people may enter the field of view of the first imaging device 210 or the second imaging device 310. In this case, the person at the forefront must be determined from the multiple people, and the generation process of face image data often takes time. However, in the movement line of this modified example, the first imaging device 210 or the second imaging device 310 can also prioritize photographing the subject who has turned an L-shaped corner, so the number of people entering the field of view of the first imaging device 210 or the second imaging device 310 can be reduced. Therefore, the load on the first information processing device 200 or the second information processing device 300 in the generation process of face image data can be reduced.

<Modification 2>
With reference to FIG. 10, another modified example of the layout of the entrance/exit management system 10 will be described.

10 is a layout diagram of an entrance/exit management system 10 according to an embodiment of the present invention. Although the layout of the entrance/exit management system 10 is the same in FIG. 10(A) and FIG. 10(B), the entrance/exit management system 10 is shown at the time of entry and exit of the subject, respectively. As shown in FIG. 10(A) and FIG. 10(B), the second gate 110b is not provided opposite the first gate 100b. Specifically, the second gate 110b is provided on the same side as the first gate 100b. Therefore, when the subject moves from the first gate 100b to the second gate 110b, the subject needs to change direction in the middle of the passage 120b. Therefore, the subject is likely to check ahead when changing direction, and the first imaging device 210 can easily capture the subject's face from the front.

To manage the movement of the subject in the passage 120b, a mark such as an arrow indicating the direction of travel may be provided on the floor or wall of the passage 120b to guide the subject. In addition, a traffic line may be formed using part of the configuration of the entrance/exit management system 10. For example, as shown in FIG. 10(A) and FIG. 10(B), a first information processing device 200, a first display device 220, a second information processing device 300, a second display device 320, and a third information processing device 400 may be placed between the first gate 100b and the second gate 110b up to the position where the subject changes direction (the U-shaped corner), so that the subject can move around these devices.

The flow line of this modification also includes curves, and the distance the subject moves can be longer than a simple straight line. In addition, in the flow line of this modification, the first image capturing device 210 or the second image capturing device 310 can preferentially capture an image of the subject who has turned a U-shaped corner, so that the load on the first information processing device 200 or the second information processing device 300 in the generation process of face image data can be reduced.
<Modification 3>
With reference to FIG. 11, still another modified example of the layout of the entrance/exit management system 10 will be described.

Figure 11 is a layout diagram of an entrance/exit management system 10 according to one embodiment of the present invention. Figures 11(A) and 11(B) show the entrance/exit management system 10 in the same layout, but show the subject entering and leaving, respectively. As shown in Figures 11(A) and 11(B), the second gate 110c is provided opposite the first gate 100c. However, in order to increase the distance the subject travels in the passage 120c, the traffic line of the passage 120c is formed to include a curve. Therefore, the subject is likely to check ahead when changing direction, and the first imaging device 210 can easily capture the subject's face from the front.

To manage the movement of the subject in the passage 120c, a mark such as an arrow indicating the direction of travel may be provided on the floor or wall of the passage 120c to guide the subject. In addition, a traffic line may be formed using part of the configuration of the entrance/exit management system 10. For example, as shown in Figures 11(A) and 11(B), multiple corners may be provided in the passage 120c, and a first information processing device 200, a second information processing device 300, and a third information processing device 400 may be placed at each of the multiple corners, so that the subject moves around these devices. In addition, a partition 130c may be provided in the vacant space to guide the subject.

The traffic line of this modified example also includes curves, allowing the subject to travel a longer distance than if the traffic line were simply straight. In addition, with the traffic line of this modified example, the first image capture device 210 or the second image capture device 310 can prioritize photographing the subject who has turned a corner, reducing the load on the first information processing device 200 or the second information processing device 300 in the process of generating face image data.

<Modification 4>
12, a description will be given of the configuration of an entrance/exit management system 10a, which is a modified example of the entrance/exit management system 10. In the following, when the entrance/exit management system 10a includes a configuration similar to that of the entrance/exit management system 10, a description of the configuration may be omitted.

FIG. 12 is a block diagram showing the configuration of an entrance/exit management system 10a according to an embodiment of the present invention. The entrance/exit management system 10a includes a first information processing device 200a, a first imaging device 210a, a first display device 220a, a warning device 230a, a second imaging device 310a, a second display device 320a, and a third information processing device 400a. Each of the first information processing device 200a, the first imaging device 210a, the first display device 220a, the warning device 230a, the second imaging device 310a, the second display device 320a, and the third information processing device 400a includes a communication unit. Therefore, each of these devices can be connected to each other via a network NW. The first information processing device 200a is used in the entrance and exit processing of the subject, and the third information processing device 400a is used in the entrance and exit management processing of the subject.

First, we will explain the entrance process using the entrance/exit management system 10a.

The first imaging device 210a can transmit image data and temperature distribution data generated by the first imaging unit 1010 to the first information processing device 200a via the network NW. The first information processing device 200a identifies the transmission as being from the first imaging device 210a and receives the image data and temperature distribution data. In the first information processing device 200a, the first face information generating unit 1020 and the temperature information generating unit 1030 generate face information and temperature information, respectively. In addition, in the first information processing device 200a, the first face matching unit 1050 executes matching processing of the subject based on the database of the registration information storage unit 1040. Furthermore, in the case of transmission from the first imaging device 210a, in the first information processing device 200a, the visitor information processing unit 1060 generates visitor information, a display signal, or a control signal.

The first information processing device 200a can transmit and receive the visitor information, display signals, and control signals generated by the visitor information processing unit 1060 to the third information processing device 400a via the network NW, and can also transmit them to the first display device 220a and the warning device 230a.

Next, we will explain the exit process using the entrance/exit management system 10a.

The second imaging device 310a can transmit image data generated by the second imaging unit 1090 to the first information processing device 200a via the network NW. The first information processing device 200a identifies that the image data is transmitted from the second imaging device 310a and receives the image data. In the first information processing device 200a, the second face information generating unit 1100 generates face information. In addition, in the first information processing device 200a, the second face matching unit 1110 executes matching processing of the subject based on the database of the registration information storage unit 1040. Furthermore, in the case of transmission from the second imaging device 310a, in the first information processing device 200a, the exiting person information processing unit 1120 generates exiting person information and a display signal.

The first information processing device 200a can transmit the exiting person information and the display signal generated by the exiting person information processing unit 1120 to the third information processing device 400a and the second display device 320a, respectively, via the network NW.

In this modified example, the first information processing device 200a includes an entrance person information processing unit 1060 and an exit person information processing unit 1120, and by identifying transmissions from the first imaging device 210a or the second imaging device 310a, the entrance person information processing unit 1060 and the exit person information processing unit 1120 can generate entrance person information and exit person information, respectively. Since the first information processing device 200a and the third information processing device 400a do not need to be installed at the construction site, the entrance and exit management system 10a can be easily installed at the construction site.

Second Embodiment
An entrance/exit management system 10A according to one embodiment of the present invention will be described with reference to Fig. 13. In the following, when the entrance/exit management system 10A includes a configuration similar to that of the entrance/exit management system 10, the description of the configuration may be omitted.

Figure 13 is a block diagram showing the configuration of an entrance/exit management system 10A according to one embodiment of the present invention. As shown in Figure 13, the entrance/exit management system 10A includes a first imaging unit 1010A, a first face information generation unit 1020A, a temperature information generation unit 1030A, an identification information acquisition unit 1210A, an entrance person information processing unit 1060A, a first display unit 1070A, a warning unit 1080A, a second imaging unit 1090A, a second face information generation unit 1100A, a second face matching unit 1110A, an exit person information processing unit 1120A, a second display unit 1130A, an entrance/exit management information processing unit 1140A, and an entrance/exit management information storage unit 1150A.

First, we will explain part of the entrance process using the entrance/exit management system 10A.

The first imaging unit 1010A can capture an image of the subject and generate image data and temperature distribution data. The image data and temperature distribution data are transmitted to the first face information generation unit 1020A and the temperature information generation unit 1030A, respectively.

The first face information generation unit 1020A can generate face information including face image data and position information of the face image data from the image data. All or part of the face information is transmitted to the temperature information generation unit 1030A and the visitor information processing unit 1060A.

The temperature information generating unit 1030A can generate temperature information including information on the subject's body temperature. The temperature information is sent to the visitor information processing unit 1060A.

The identification information acquisition unit 1210A can acquire identification information contained in the IC chip of an identity verification medium held by the subject. The identity verification medium is, for example, but not limited to, a My Number card, a passport, or an ID card. Any identity verification medium can be used as long as it can identify the subject. The identification information of the identity verification medium can be acquired by a reader device or the like. The identification information is transmitted to the visitor information processing unit 1060A.

The visitor information processing unit 1060A can link face information, temperature information, and identification information to generate visitor information. The visitor information is sent to the entrance/exit management information processing unit 1140A.

The entrance/exit management information processing unit 1140A can generate entrance/exit management information in which visitor information is converted into a database. The generated entrance/exit management information is stored in the entrance/exit management information storage unit 1150A.

Next, we will explain part of the exit process using the entrance/exit management system 10A.

The second imaging unit 1090A can capture an image of the subject and generate image data. The image data is sent to the second face information generation unit 1100A.

The second face information generation unit 1100A can generate face information including face image data from the image data. All or part of the face information is transmitted to the second face matching unit 1110A and the exiting person information processing unit 1120A.

The second face matching unit 1110A can obtain visitor information from the entrance/exit management information storage unit 1150A and match the facial image data of the facial information with the facial image data of the visitor information. Furthermore, if the second face matching unit 1110A is able to match the target person through matching processing, it transmits all or part of the visitor information of the matched visitor to the exit person information processing unit 1120A.

The exiting person information processing unit 1120A can link face information and entrance information to generate exiting person information. The exiting person information is sent to the entrance/exit management information processing unit 1140A.

When there is entrant information corresponding to the exiting person information, the entrance/exit management information processing unit 1140A can generate entrance/exit management information in which the entrant information and the exiting person information are linked. In contrast, when there is no entrant information corresponding to the exiting person information, the entrance/exit management information processing unit 1140A can generate entrance/exit management information in which the exiting person information is organized into a database.

In the entrance/exit management system 10A, when a subject enters, visitor information including the subject's identification information is generated, so there is no need to create registration information in advance. In other words, when a subject enters, registration information for the subject is generated. In addition, when a subject leaves, the subject is matched based on the registration information (visitor information) generated at the time of entry. Therefore, even if registration information is not created in advance, the entrance/exit management system 10A can be used to manage the entrance and exit of subjects.

Third Embodiment
An entrance/exit management system 10B according to an embodiment of the present invention will be described with reference to Fig. 14. In the following, when the entrance/exit management system 10B includes a configuration similar to that of the entrance/exit management system 10, the description of the configuration may be omitted.

Figure 14 is a schematic diagram showing the configuration of a first display device 220B of an entrance/exit management system 10B according to one embodiment of the present invention. As shown in Figure 14, facial image data 221B of the registration information, facial image data 222B of the facial information, registrant information 223B of the registration information, and a first icon 224B are displayed on the screen of the first display device 220B. In addition, the first display device 220B is provided with an image sensor 225B on the screen side. It is preferable that the image sensor 225B be capable of capturing images in the visible light region and the infrared light region.

When the subject looks at the facial image data 221B of the registration information or the registrant information 223B of the registration information displayed on the screen of the first display device 220B and confirms that the match is incorrect, the subject touches the first icon 224B to input that it is a false detection. The first display unit 1070 of the first display device 220B generates a false detection signal and uses the image sensor 225B to capture an image of the subject's face and generate image data and temperature distribution data. The generated false detection signal, image data, and temperature distribution data are transmitted to the first information processing device 200.

In the entrance/exit management system 10B, if matching of the subject based on the image captured by the first imaging device 210 is a false positive, the subject matching process can be performed again based on the image data and temperature distribution data transmitted from the imaging element 225B. In other words, in the entrance/exit management system 10B, the subject can be matched based on the image captured by the imaging element 225B, which is closer to the subject than the first imaging device 210. This improves the accuracy of the subject matching process.

Fourth Embodiment
A unit panel 20 including an entrance/exit management system according to an embodiment of the present invention will be described with reference to Figures 15 and 16. When the entrance/exit management system included in the unit panel 20 includes a configuration similar to that of the entrance/exit management system 10, a description of the configuration may be omitted.

15 and 16 are schematic perspective and plan views, respectively, of a unit panel 20 according to one embodiment of the present invention. The unit panel 20 includes a panel material 500C, and the panel material 500C is provided with all or part of the configuration of an entrance/exit management system. The entrance/exit management system provided in the panel material 500C is, for example, a first information processing device 200C, a first imaging device 210C, a first display device 220C, a warning device 230C, a second information processing device 300C, a second imaging device 310C, or a second display device 320C. Therefore, if the unit panel 20 is installed at the entrance/exit of a construction site, the entrance/exit management system provided in the unit panel 20 can be used to manage the entrance and exit of workers at the construction site.

The material of the panel material 500C is not particularly limited. For example, wood or resin material can be used as the panel material 500C. The panel material 500C is also provided with an opening 510C for the subject to pass through.

When the entrance/exit management system included in the unit house 30 includes a configuration similar to that of the entrance/exit management system 10, the description of the configuration may be omitted.

17 and 18 are schematic perspective views showing the exterior and schematic plan views showing the internal configuration of a unit house 30 according to one embodiment of the present invention, respectively. The unit house 30 includes a box-shaped body 600D consisting of four side walls, a ceiling surface covering the upper part of the space surrounded by the four side walls, and a floor surface covering the lower part of the space surrounded by the four side walls, and the box-shaped body 600D is provided with all or part of the configuration of the entrance and exit management system. The entrance and exit management system provided in the box-shaped body 600D is, for example, a first information processing device 200D, a first imaging device 210D, a first display device 220D, a warning device 230D, a second information processing device 300D, a second imaging device 310D, or a second display device 320D. Therefore, if the unit house 30 is installed at the entrance and exit of a construction site, the entrance and exit management system provided in the unit house 30 can be used to manage the entrance and exit of workers at the construction site.

The side walls, ceiling, and floor of the box-shaped body 600D may each be made of a single member or a plurality of members. The box-shaped body 600D may also be constructed by forming a frame using pillars or beams, and fixing panel materials to the frame. The box-shaped body 600D may be a so-called container, prefabricated house, or storage room, or may be a simple building used for a house, office, warehouse, store, or the like.

The modular house 30 may be able to be moved as is to the construction site and installed there, or may be divided into several components that can be assembled and installed at the construction site.

Of the four side walls of the box-shaped body 600D, a first door 610D and a second door 620D are provided on two opposing side walls. The first door 610D and the second door 620D correspond to a first gate and a second gate, respectively, and the unit house 30 is installed so that the second door 620D is connected to the entrance and exit of the construction site. When a subject enters the construction site, the subject enters through the first door 610D, entry processing is performed using the entrance and exit management system, and the subject exits through the second door 620D. When a subject exits the construction site, the subject enters through the second door 620D, exit processing is performed using the entrance and exit management system, and the subject exits through the first door 610D.

If a window is provided on the side wall surface, first door 610D, or second door 620D of the box-shaped body 600D, it is preferable that a light-shielding member such as a curtain, blind, or smoke film is provided on the window to block light entering the unit house 30 through the window. By blocking the light from the window, the illuminance inside the box-shaped body 600D can be kept constant. Therefore, the subject can always be photographed under the same illuminance conditions, improving the accuracy of the subject matching process.

An air conditioner 650D including an indoor unit 651D, an outdoor unit 652D, and piping 653D is provided on the side wall surface of the box-shaped body 600D. By providing the air conditioner 650D, the unit house 30 can maintain a constant temperature inside the box-shaped body 600D. This allows the subject to always be photographed under the same temperature conditions, improving the accuracy of measuring the subject's body temperature. In addition, a ventilation opening or a ventilation fan may be provided on the side wall surface to circulate air inside the box-shaped body 600D. The indoor unit 651D, ventilation opening, and ventilation fan may be installed not only on the side wall surface but also on the ceiling surface.

It is also preferable that the unit house 30 is equipped with a rechargeable battery unit 660D. By equipping the unit house 30 with the battery unit 660D, even if it is difficult to supply power from outside at the construction site, power can be supplied from the battery unit 660D to each device of the unit house 30. The unit house 30 can also be equipped with a power generation device (for example, a solar power generation device or a wind power generation device installed on the ceiling or wall, or a self-generating power generator installed under the floor, etc.).

Furthermore, the unit house 30 may be equipped with a sensor that detects the opening and closing of the first door 610D or the second door 620D. By equipping the unit house 30 with a sensor, for example, when the first door 610D or the second door 620D is opened, the power supply of the entrance and exit management system of the unit house 30 can be turned on.

The unit house 30 according to this embodiment can be installed by moving the box-shaped body 600D and attaching several components, so it can be easily installed or removed anywhere. Therefore, during the construction period at a construction site, or during the period when an event facility or event venue is held, the unit panel 20 can be temporarily installed and the entrance and exit management system can be used to manage the entrance and exit of the target person.
