  ADVANTAGE OF THE INVENTION According to this invention, usability can be improved because it can confirm the face of the person (suspicious person candidate) who was not authenticated as the person permitted to enter / exit the dwelling unit.

  Hereinafter, an embodiment in which the present invention is applied to an apartment house such as an apartment will be described in detail with reference to the drawings. However, it is needless to say that the houses to which the technical idea of the present invention can be applied are not limited to collective houses, and can be applied to detached houses.

  FIG. 2 shows a system configuration example of the security system for collective housing of this embodiment. The security system for apartment houses includes a face authentication device A, a visitor communication device (lobby intercom) B, an alarm monitoring panel C, an electric lock control device D, an elevator control panel E, a delivery box control panel F, and a system control panel G. It consists of a dwelling unit (interphone device or dwelling unit information panel) H installed in each dwelling unit, and authenticates the person who enters and exits the apartment building, which is a management area, with a face shape by the face authentication device A To do.

  The lobby intercom B has a camera for imaging the visitor, a call device for calling with the alarm monitoring panel C and the dwelling unit H, a numeric keypad for the visitor to enter the dwelling unit number of the visited dwelling unit, etc. It is installed outside the common entrance J, which is the entrance to the housing complex. When a visitor operates the numeric keypad of the lobby intercom B and inputs the dwelling unit number of the visited unit, the dwelling unit H installed in the dwelling unit of the dwelling unit number is sent from the lobby intercom B via the alarm monitoring panel C. Thus, a call signal and a visitor image captured by the camera of the lobby intercom B are transmitted. Then, in the dwelling unit H that has received the calling signal, the video received from the lobby intercom B is displayed on the display and the calling sound is generated from the speaker. When the resident of the dwelling unit presses the response button of the dwelling unit H, a communication path is formed between the dwelling unit H and the lobby intercom B, and the visitor and the resident use the lobby intercom B and the dwelling unit H, respectively. You can make a call. Since this type of lobby interphone B and alarm monitoring panel C are well known in the art, the detailed illustration and description thereof will be omitted.

  The electric lock control panel D controls locking / unlocking of an electric lock (not shown) provided at the common entrance J. The elevator control panel E controls the operation of an elevator (not shown) installed in the apartment house. The delivery box control panel F controls locking / unlocking of delivery boxes installed in the apartment house. The system control panel G causes the electric lock control panel D to unlock the electric lock or causes the elevator control panel E to operate the elevator according to the control command transmitted from the dwelling unit H and the authentication result of the face authentication device A. Or let the delivery box control panel F unlock the delivery box. The face authentication apparatus A performs face authentication of whether or not the person is a registrant (resident) by comparing the face shape of the person outside the common entrance J with a template registered in advance. The authenticating information is transmitted to the board G. When the system control panel G receives the authentication information from the face authentication device A, the system control panel G causes the electric lock control panel D to unlock the electric lock of the common entrance J, causes the elevator control panel E to operate the elevator, Let the control panel F unlock the delivery box. On the other hand, when the authentication by the face authentication device A is impossible, the system control panel G receives the information indicating that the authentication is impossible from the face authentication device A, so that the electric lock control panel D does not unlock the electric lock, and the elevator control panel E does not operate the elevator, and the delivery box control panel F does not unlock the delivery box. Since the electric lock control device D, the elevator control panel E, and the delivery box control panel F are well known in the art, detailed illustration and description thereof are omitted.

  As shown in FIG. 1B, the dwelling unit H has a speech path between the sound input / output unit 20 that has a microphone and a speaker and inputs and outputs sound, and the lobby intercom B via the communication line Lx. The communication unit that outputs the incoming voice sent from the lobby intercom B by the sound input / output unit 20 and sends the outgoing voice input from the sound input / output unit 20 to the communication path and sends it to the lobby intercom B 21, a display device such as a liquid crystal display, a display unit 22 for displaying an image transmitted from the lobby intercom B via the communication line Lx, a response button and other operation buttons, The operation input receiving unit 23 that receives an operation input corresponding to each button when the button is pressed, and the communication unit 24 that transmits and receives an audio signal, a video signal, and a control signal via the communication line Lx. , And a processing unit 25 which consists of a microcomputer, controls the respective units. The dwelling unit H is assigned an address for communication (for example, dwelling unit number). Using this address, the lobby intercom B, the alarm monitoring panel C, the system control panel G, the face authentication device A, and each dwelling unit H Can communicate individually. The communication line Lx is composed of three lines: a speech line for transmitting an audio signal, a video line for transmitting a video signal transmitted from the lobby intercom B, and a signal transmission line for transmitting a calling signal, a control signal, and the like. All signals may be transmitted by two lines or one line by using frequency division multiplexing transmission technology.

  As already explained, when a visitor operates the numeric keypad of the lobby intercom B and enters the dwelling unit number of the visited dwelling unit, the lobby intercom B alerts the dwelling unit H installed in the dwelling unit of that dwelling unit number. Via the monitoring board C, a call signal and a visitor image captured by the camera of the lobby intercom B are transmitted via the communication line Lx. In the dwelling unit H having the dwelling unit number as an address, the arithmetic processing unit 25 rings a ringing tone from the speaker of the sound input / output unit 20 in accordance with a calling signal received by the communication unit 24 and a video received by the communication unit 24. The signal is signal-processed and a video of the visitor is displayed on the display unit 22. When the response button is pressed during a predetermined time (several minutes) after the ringing sound is started and the operation input receiving unit 23 receives the operation input, the arithmetic processing unit 25 forms a communication path in the calling unit 21. Thus, it is possible to exchange audio signals with the lobby intercom B. When a predetermined call time (several minutes) elapses after the call path is formed or the response button is pressed again, the arithmetic processing unit 25 causes the call unit 21 to open the call path and display the display unit. The video output to 22 is stopped and the standby state is restored.

  FIG. 1A shows a block diagram of the face authentication apparatus A of the present embodiment. The light modulation camera unit 1 serving as an imaging unit controls one or a plurality of light emitting diodes that emit infrared light, a driving circuit that lights the light emitting diodes, and a driving circuit, and the light emitting diodes at a very high frequency (for example, 10 megahertz). A light emission control unit for irradiating modulated light to the target space by driving the image sensor, an image sensor having sensitivity to infrared light (for example, CCD <charge coupled device>), and condensing light incident from the target space on the image sensor Based on the timing signal output from the lens and the light emission control unit, processing for extracting only the reflected light component of infrared light from the output of each pixel of the image sensor in synchronization with the light emission period of the light emitting diode (hereinafter referred to as “synchronous detection processing”). And a signal processing circuit that generates a light-modulated image with the reflected light component extracted by the synchronous detection processing as a pixel value. The light modulation camera unit 1 continuously generates light modulation images at a predetermined frame period, and the generated light modulation images are stored (stored) in the image memory 2 in time series. However, since the specific configuration of the light modulation camera unit 1 is already known as described in Patent Document 2, illustration and detailed description thereof are omitted.

  The face image extraction unit 3 extracts a face image (face area) of a person from a light modulation image stored in the image memory 2, and a feature amount of the person's face from the extracted face image (for example, A feature amount extraction process is performed to extract information corresponding to features of facial organ shapes such as eyes, nose, and mouth. The face image extraction unit 3 extracts a feature amount when a face image of a person existing in the target space is extracted from images of a plurality of frames continuously captured within a predetermined time (for example, several seconds to several tens of seconds). Execute the extraction process. However, since the face image extraction process, the feature amount extraction process, and the collation process are already well-known techniques as described in Patent Document 2, detailed description thereof is omitted.

  In addition, the permitter verification unit 4 compares the feature amount (face shape) extracted by the face image extraction unit 3 with the permitter template stored (registered) in the permitter template storage unit 5 in advance. If the shape matches any permitter template, a matching result indicating that matching is possible is output to the control unit 10, and if the face shape does not match any permitter template, the matching result indicating that matching is impossible is controlled. To the unit 10. When the control unit 10 receives a verification result indicating that verification is possible, the communication unit 11 notifies the system control panel G of an authentication result indicating that authentication is possible. When the control unit 10 receives a verification result indicating that verification is not possible, the communication unit 11 transmits an authentication result indicating that authentication is impossible. To the system control panel G.

  If the authentication result received from the face authentication device A is authentic, the system control panel G causes the electric lock control panel D to unlock the electric lock, causes the elevator control panel E to operate the elevator, and further delivers the delivery box control panel. Let F unlock the delivery box. On the other hand, if the authentication result received from the face authentication device A cannot be authenticated, the system control panel G does not perform any control on the electric lock control panel D, the elevator control panel E, and the delivery box control panel F. Therefore, it is possible to prevent a person who has not been registered in advance (a person other than the resident of the apartment house) from entering the house without permission. Here, when the collation result is collation, the control unit 10 of the face authentication apparatus A provides the identification information corresponding to the permitter template determined to be collation by the permitter collation unit 4 as the permitter template storage unit 5. , The original face image of the face shape determined to be collable is acquired from the face image extraction unit 3 and acquired from the face image extraction unit 3 for the dwelling unit H corresponding to the identification information (dwelling unit number). The face image is transmitted from the communication unit 11 together with the identification information. In the dwelling unit H whose address is the dwelling unit number, the arithmetic processing unit 25 displays at least one of the face image and the identification information received by the communication unit 24 on the display unit 22, so that It can be confirmed by the face image or identification information displayed on the display unit 22 who has returned home.

  In addition, the facial shape that is determined not to match any of the permitter templates by the permitter verification unit 4 is used as a suspicious candidate template by the control unit 10 to identify the suspicious candidate candidate. The information is stored (registered) in the suspicious candidate template storage unit 7 in association with the identification information. In addition, the control unit 10 acquires the face image from which the face shape is extracted from the face image extraction unit 3 and stores the face image in the face image storage unit 12 in association with the suspicious person candidate identification information.

  The following description is based on the assumption that at least one suspicious candidate template is stored in the suspicious candidate template storage unit 7.

  In the face authentication apparatus A, the suspicious candidate verification unit 6 matches the facial shape determined to be unmatched by the permitter verification unit 4 with the suspicious candidate template stored in the suspicious candidate template storage unit 7. To do. When it is determined by the suspicious candidate verification unit 6 that the template matches any suspicious candidate template, the control unit 10 increments a counter corresponding to the suspicious candidate identification information of the suspicious candidate template. On the other hand, when it is determined by the suspicious person candidate matching unit 6 that the suspicious person candidate matching template 6 does not match any suspicious person candidate template, the control part 10 identifies the suspicious person candidate using the face shape as a new suspicious person candidate template. The information is stored in the suspicious candidate template storage unit 7 in association with the suspicious candidate identification information. When the count value of the counter exceeds a threshold value (an integer of 2 or more) during a predetermined period (tens of minutes to several hours), the control unit 10 identifies the suspicious person candidate identification information of the suspicious person candidate template. Is read from the face image storage unit 12, and the read face image is transmitted from the communication unit 11 to all the dwelling units H or the dwelling units H of the predetermined dwelling units or an alarm monitoring panel installed in the manager's room Send to C. However, if the counter is not incremented even after the predetermined time has elapsed, the control unit 10 initializes the counter.

  In each dwelling unit H (or alarm monitoring panel C), the arithmetic processing unit 25 displays the face image received by the communication unit 24 on the display unit 22, thereby displaying the face image on the display unit 22 for the resident of the dwelling unit. The suspicious candidate can be confirmed with the face image. In the situation where the suspicious candidate face image is displayed on the display unit 22, when the operation input receiving unit 23 of the dwelling unit H receives an operation input for suspicious person registration, the arithmetic processing unit 25 instructs the suspicious person registration. A control command is generated, and a control signal including the control command is transmitted from the communication unit 24 to the face authentication apparatus A. On the other hand, in the situation where the face image of the suspicious person candidate is displayed on the display unit 22, when the operation input accepting unit 23 of the dwelling unit H accepts the operation input of the permitter registration, the arithmetic processing unit 25 performs the permitter registration. A control command to be instructed is generated, and a control signal including the control command is transmitted from the communication unit 24 to the face authentication apparatus A. The operation input for suspicious person registration and permitter registration may be received by operating each dedicated operation button of the operation input receiving unit 23, or other operation buttons (for example, response The button may be accepted by a long press.

  When the control unit 10 of the face authentication apparatus A receives the control command for suspicious person registration by the control signal received by the communication unit 11, the suspicious person corresponding to the suspicious person candidate identification information of the face image transmitted to the dwelling unit H is transmitted. The candidate template is stored (registered) in the suspicious person template storage unit 9 in association with the suspicious person identification information for identifying the suspicious person as the suspicious person template. On the other hand, when the control signal for permitter registration is received by the control signal received by the communication unit 11, the control unit 10 suspicious candidate candidate corresponding to the suspicious candidate identification information of the face image transmitted to the dwelling unit H earlier. The authorization template is stored (registered) in the authorized person template storage unit 5 in association with the authorized person identification information for identifying the authorized person as the authorized person template.

  In a situation where at least one suspicious person template is stored in the suspicious person template storage unit 9, the suspicious person candidate checking part 6 uses the suspicious candidate checking part 6 as the suspicious candidate checking part 6 for the face shape determined not to be checked by the permitter checking part 4. The suspicious person candidate template stored in the suspicious person candidate template storage unit 7 is collated, and the suspicious person collation unit 8 also collates with the suspicious person template stored in the suspicious person template storage unit 9. When the suspicious person collation unit 8 determines that the suspicious person template matches the suspicious person template, the control unit 10 acquires a face image corresponding to the suspicious person identification information of the suspicious person template from the face image extraction unit 3, and The face image acquired together with the suspicious person appearance information notifying that the person has appeared is sent to all the dwelling units H or the dwelling units H of the predetermined dwelling units from the communication unit 11 or the alarm monitoring panel C installed in the administrator room. Send to address.

  In each dwelling unit H (or alarm monitoring panel C), the arithmetic processing unit 25 causes the display unit 22 to display the face image received by the communication unit 24 and a warning sound or a warning message (for example, “a suspicious person has appeared. Etc.) from the speaker of the sound input / output unit 20 to warn the resident of the dwelling unit that the suspicious person has appeared to the resident of the dwelling unit. Alternatively, a display lamp (not shown) provided in the dwelling unit H may be turned on or blinked to warn of the appearance of a suspicious person.

  If the suspicious person verification unit 8 determines that the template matches the suspicious person template, the suspicious person appearance information is transmitted from the control unit 10 to the alarm monitoring panel C via the system control panel G, and the suspicious person appearance information is displayed. Accordingly, if the alarm monitoring panel C prohibits the transmission of the calling signal from the lobby intercom B to the dwelling unit H, it is possible to prevent an unnecessary ringing sound from a suspicious person from being emitted from the speaker of the dwelling unit H.

  Thus, according to the present embodiment, if the resident of the dwelling unit determines that the suspicious candidate whose face image is displayed on the display unit 22 is a suspicious person, the operation input accepting unit 23 inputs an operation input for suspicious person registration. The facial shape extracted from the face image is stored in the suspicious person template storage unit 9 as a suspicious person template, and thereafter, the suspicious person's face authentication is performed using the suspicious person template, and the suspicious person Since the warning is issued from the dwelling unit H when it is authenticated, the security level in the security system for apartment houses can be increased. In addition, the person registered as a suspicious candidate is a resident's acquaintance, and the resident inputs the permitter registration operation from the operation input receiving unit 23 of the dwelling unit H, so that the facial shape of the person is used for the permitter. After that, it can be registered as a template, and since then it is collated by the permitter collation unit 4 in the same manner as the resident, so that it can freely enter and exit the dwelling.

  By the way, in the lobby intercom B, when any of the dwelling unit numbers is input by operating the numeric keypad, the dwelling unit number and a call request are transmitted to the alarm monitoring panel C, and the alarm monitoring panel C is responded to this call request. A call signal is transmitted to the dwelling unit H of the dwelling unit number, but when the alarm monitoring board C receives a call request, the face image is sent to the face authentication apparatus A via the system control board G. Send a save request for. In response to the storage request received from the alarm monitoring panel C, the control unit 10 of the face authentication device A correlates the face image acquired from the face image extraction unit 3 with the date and time when the image was captured, the stay time, and the dwelling unit number. The image is stored in the image storage unit 12. Then, upon receiving a distribution request for the stored face image from the dwelling unit H via the alarm monitoring panel C and the system control panel G, the control unit 10 of the face authentication apparatus A stores it in the face image storage unit 12. The face image corresponding to the dwelling unit number of the distribution request source dwelling unit H is read out from the face image, and the read out face image and the date and time information of the imaged and staying time are transmitted from the communication unit 11 to the distribution requesting dwelling unit. Distribution (transmission) to H.

  In the dwelling unit H, the arithmetic processing unit 25 receives the face image and other information distributed from the face authentication device A from the communication unit 24 and causes the display unit 22 to display them. In the situation where the face image stored in the face authentication device A is displayed on the display unit 22, when the operation input receiving unit 23 of the dwelling unit H receives an operation input for suspicious person registration, the arithmetic processing unit 25 is suspicious. A control command for instructing user registration is generated, and a control signal including the control command is transmitted from the communication unit 24 to the face authentication apparatus A. On the other hand, in the situation where the face image is displayed on the display unit 22, when an operation input for permitter registration is received by the operation input receiving unit 23 of the dwelling unit H, the arithmetic processing unit 25 controls the permitter registration. And a control signal including the control command is transmitted from the communication unit 24 to the face authentication apparatus A. Note that in the face authentication apparatus A, the face shape extracted from the face image distributed to the dwelling unit H by the control unit 10 in accordance with the control command received from the dwelling unit H is used as a suspicious person template or a permitter template. The information is stored in the suspicious person template storage unit 9 or the authorized person template storage unit 5.

  Therefore, not only a person displayed on the display unit 22 in real time but also a person whose face image has been captured in the past can register (store) a face shape (template) as a suspicious person or an authorized person.
