Description

The present invention relates to an information management device, an information management system, an information management method, and a program.

When a disaster occurs, disaster response headquarters are overwhelmed with response efforts and tend to get confused with information. In such situations, manual input on paper or a whiteboard is suitable for recording requests from disaster-affected areas and the situation in disaster-stricken areas. For example, if you write information on a whiteboard in chronological order and in a table format, the workload is relatively low and you can record all information even in an emergency. Also, by writing on a whiteboard in table format, it is possible to ensure that the information can be viewed at a glance.

Patent Document 1 discloses a projection method in which an image projected by a projector is photographed, and when a mismatch between the original projected image and the photographed image is detected, a new image is projected by superimposing the image of the mismatched portion on the original image. An apparatus is disclosed. When using this projection device, for example, when projecting information onto a whiteboard using a projector, the user can present the desired document paper within the projection range, or pin up the document paper onto the whiteboard. In such cases, it becomes possible to immediately reflect the photographed image in the projection content.

Japanese Patent Application Publication No. 2009-115984

In the method of writing information on a whiteboard, when the amount of information is large, the information is often written across multiple whiteboards. In this case, the visibility of information is greatly impaired. One way to avoid this problem in operation is to enter only information that exceeds a certain level of importance, for example. If you follow this, it is possible to suppress the amount of information, but (1) the degree of importance is relative and changes over time; (2) the degree of importance depends on the subjectivity of the individual, so there is no uniform evaluation. (3) Since the duration of the emergency situation is unknown, the upper limit of information to be entered is unknown. There is a need for an information management method that can record information in a less burdensome manner without leaking it, while also ensuring visibility even when the amount of information increases.

Therefore, an object of the present invention is to provide an information management device, an information management system, an information management method, and a program that can solve the above-mentioned problems.

<Embodiment>
Information management methods according to each embodiment of the present invention will be described below with reference to FIGS. 1 to 13.
(System configuration)
FIG. 1 is a first diagram showing an example of an information management system according to an embodiment of the present invention.
The information management system 1 shown in FIG. 1 photographs information written in a fixed format over time on media 40a and 40b that can be viewed simultaneously by multiple people and that allows manual input of information. Only necessary information is extracted from the information management device 10 and displayed on the display screen of the information management device 10 or projected onto the screen 50 to share the information while managing the information manually input into the media 40a, 40b. Necessary information changes over time, and the information management system 1 provides a means to easily change the necessary information.

As illustrated, the information management system 1 includes an information management device 10, cameras 20a and 20b, a projector 30, media 40a and 40b, and a screen 50. Cameras 20a, 20b and projector 30 are connected to information management device 10. The media 40a, 40b are, for example, paper, a whiteboard, a blackboard, or the like. When a disaster occurs, various disaster information is received at various times from multiple information channels such as the fire department, police, and Self-Defense Forces. The person in charge manually inputs the information collected in the media 40a and 40b in a table format. FIG. 2 shows an example of information manually input into the medium 40a.

FIG. 2 is a diagram showing an example of information entry in an embodiment of the present invention.
On the medium 40a, ruled lines are displayed so that the time of disaster occurrence, content, type, situation, and importance of the disaster can be written in a table format. The person in charge manually enters the time the disaster occurred or the date and time the disaster information was received (for example, 10:30:30 on November 19, 2019) in the "Date and Time" field, and then enters the time in the "Content" field. Manually enter the details of the disaster (e.g., ``knee-deep flooding occurred in ~ area''). Regarding the "Type", "Progress", and "Importance" columns, the person in charge writes information into each column by attaching magnets of predetermined colors as necessary. In FIG. 2, the color of each magnet is indicated by letters. "Type" indicates the type of disaster such as earthquake, fire, flood, etc. Alternatively, the type may be used to represent an organization that deals with disasters, such as a fire department, police, or self-defense force. "Progress" indicates the progress of the disaster. Moreover, "importance" indicates the importance of the information. In this embodiment, "type", "progress", and "importance" are called attribute information, and the information is input by attaching colored magnets. For example, in the case of the "Type" column, if the received disaster information is a flood, a blue magnet is attached, if it is a fire, a red magnet is attached, and if it is an earthquake, a yellow magnet is attached. Furthermore, when the response to the disaster is completed, the red magnet is removed from the "Type" column. "Progress" and "Importance" are marked with colored magnets that correspond to the progress, importance, and urgency of the disaster.

In the example of FIG. 2, the medium 40a is divided into left and right areas, and disaster information is manually input line by line in each area on the left and right, using date and time, content, type, progress status, and importance as one unit. For example, disaster information is input in order from top to bottom in the left area, and when the bottom line is reached, disaster information is input one line at a time starting from the top line in the right area. Disaster information once input is stored without being deleted. However, even after disaster information is input, it may change over time. For example, in the case of a flood, even if the water is below the knees when information is first received, the situation may progress over time to the point where the water reaches below the eaves of the first floor. In such cases, the person in charge should not attach a magnet when the water is below knee level, attach a blue magnet when the water is below waist level, attach a yellow magnet when the water is at chest level, and then attach a yellow magnet when the water is below knee level. As the depth increases, a red magnet is attached. In this way, the progress of a disaster can be recorded and displayed by replacing magnets with different colors. In addition, in cases where the scale of damage is large, the disaster response headquarters needs to prioritize the response. Therefore, for example, a red magnet is attached to the "importance" of disaster information that is highly urgent or large-scale, and when the urgency or scale decreases, it is replaced with a yellow magnet, and organizations in the area are assigned countermeasures. If the disaster information is to be left to the disaster, a blue magnet is attached, but if progress is being monitored, the magnet is removed, etc., and the importance, urgency, etc. of the disaster information can be entered and displayed. Further, when the "type" column is used as a mark indicating the organization that takes measures, the organization that takes measures may change depending on the situation of the disaster. In such a case, the person in charge attaches a magnet of the color corresponding to the organization to be dealt with in the "Type" column.

The method of writing information on a medium 40 such as a whiteboard is a method of managing information that has a small input burden and can ensure visibility at a glance. When trying to express the importance of information, it is difficult to respond when the importance changes. If the method of writing the attributes of information by attaching a magnet of a predetermined color as in this embodiment is, you can simply change the magnet of a different color depending on the situation and update the latest attributes of the information. The information can be updated to reflect the

Return to Figure 1. The camera 20a photographs the medium 40a at predetermined time intervals. Camera 20b photographs medium 40b at predetermined time intervals. The cameras 20a and 20b output captured images to the information management device 10 each time. The information management device 10 acquires images acquired from the cameras 20a and 20b, and extracts only necessary disaster information specified by the user from the latest images. Necessary disaster information is specified by attribute information of "type", "progress", and "importance". For example, when the user specifies flood damage for "type", the information management device 10 adds a blue magnet indicating flood damage to the "type" column of the disaster information written on the media 40a, 40b. Only the disaster information received is extracted and displayed on the display unit 18. Alternatively, the information management device 10 may display the extracted disaster information on the screen 50 using the projector 30. The projector 30 projects the extracted disaster information onto the screen 50 according to instructions from the information management device 10.

Note that in the configuration of the information management system 1 illustrated in FIG. 1, the number of cameras 20 and media 40 may be one or three or more. Further, the information management device 10 may be provided separately for each of the cameras 20a and 20b. Further, the medium 40a, 40b may be configured to be photographed by one camera 20. As described later (FIG. 11), the information management system 1 can be configured across multiple locations. Hereinafter, when there is no need to distinguish between the media 40a and 40b, the medium 40 may be referred to as the medium 40, and when there is no need to distinguish between the cameras 20a and 20b, the medium may be referred to as the camera 20.

(Configuration of information management device)
FIG. 3 is a functional block diagram of an information management device in an embodiment of the present invention.
The information management device 10 is configured by a computer such as a server terminal or a PC (personal computer). The information management device 10 includes an image acquisition section 11, an image processing section 12, an extraction section 13, a storage section 14, an input reception section 15, a control section 16, an output section 17, and a display section 18. .
The image acquisition unit 11 acquires images photographed by the camera 20 at predetermined time intervals and their photographing times, and records them in the storage unit 14 . The image acquired by the image acquisition unit 11 will be referred to as a photographed image.
The image processing unit 12 performs image processing on the photographed image, recognizes necessary information from the photographed image, and cuts out a part of the photographed image. For example, the image processing unit 12 detects the state of a magnet attached to any one of "type", "progress status", and "importance" from the captured image. The image processing unit 12 associates attributes and attribute values with respect to the rows to which the magnets are attached, based on the position and color of the detected magnets. The attribute is one of "type", "progress status", and "importance", and the attribute value is a value set for a color such as red, yellow, or blue. Note that the state of the magnet includes not only the color of the magnet but also the fact that the magnet is not attached. Furthermore, the image processing unit 12 cuts out the information entered in the "date and time" and "content" columns for each row. To cut out the information, for example, an image within each column surrounded by ruled lines may be cut out from the photographed image, or characters written in each column may be recognized using OCR (optical character recognition).

The extraction unit 13 extracts information having attribute information specified by the user from among the disaster information included in the photographed image.
The storage unit 14 is a storage medium such as a RAM (Random Access Memory) or an HDD (Hard Disk Drive). The storage unit 14 stores photographed images acquired by the image acquisition unit 11, information extracted by the image processing unit 12, information extracted by the extraction unit 13, and the like.
The input reception unit 15 receives setting information and the like input by the user to the information management device 10.
The control unit 16 generates an image to be displayed on the display unit 18 and an image to be projected via the projector 30.
The output unit 17 outputs the image generated by the control unit 16 to either the display unit 18 or the projector 30, or both.
The display unit 18 is a display device such as a liquid crystal display or an organic EL (Electroluminescence) display.
The storage unit 14 and the display unit 18 may be configured integrally with the information management device 10, or may be connected to the information management device 10 as independent devices.

(Display target settings)
FIG. 4 is a diagram showing an example of an extraction condition setting screen according to an embodiment of the present invention.
The extraction condition setting screen 100 illustrated in FIG. 4 is a screen generated by the control unit 16.
On the extraction condition setting screen 100, one or more conditions to be extracted can be selected for each of type, progress status, and importance level. For example, if the user wants to see only disaster information related to fire, select "Type 3 (red)", and if the user wants to see information about fire and flood damage, select "Type 3 (red)" and "Type 1 (red)". blue). Furthermore, if you want to see only information that has progressed, select "Status 3 (red)", and if you want to see only information with high importance, select "Importance 3 (red)". Furthermore, the user can select multiple attributes among type, progress status, and importance level. For example, if the user wants to extract only disaster information of a fire that is progressing and has a high importance level, the user can select "Type 3 (red)", "Status 3 (red)", and "Importance level 3 (red)". select. Furthermore, if the user wants to extract disaster information that does not have a magnet attached to a certain attribute, the user selects "(none)" for that attribute. For example, if the user selects "Ended (none)" for the type, "None (none)" for the progress status, and "None (none)" for the importance level, no magnet will be attached to any attribute column. Disaster information that does not exist is extracted. Further, if no extraction conditions are specified for a certain attribute, the user does not make a selection for that attribute. For example, if the user selects "Type 3 (red)" and does not select anything regarding the progress status or importance level, the magnet attached to the "progress status" or "importance level" column of the medium 40 All disaster information with a red magnet attached in the "Type" column is extracted, regardless of its presence or color. Furthermore, on the extraction condition setting screen 100, it is possible to select whether to "display" or "not display" the deleted information. The erased information refers to disaster information that was once written on the medium 40 and then deleted. When the amount of disaster information increases, it may become impossible to write all the information on the media 40a, 40b. In such a case, the information written on the media 40a, 40b is temporarily erased. The information written on the media 40a, 40b is photographed by the cameras 20a, 20b and stored in the storage unit 14. If you select "Display" erased information, the erased disaster information will be displayed in addition to the disaster information currently written on the media 40a and 40b. If you select "Do not display", the information currently written on the media 40a and 40b will be displayed. Only the disaster information entered in 40a and 40b is displayed. After selecting the extraction conditions, the user presses the extraction button 101. Then, the input receiving unit 15 acquires the extraction conditions set on the extraction condition setting screen 100 and outputs the information to the extraction unit 13 as search conditions. The extraction unit 13 extracts information on the rows attached with magnets that meet the extraction conditions from the image acquired by the image acquisition unit 11 and outputs the information to the control unit 16 . The control unit 16 generates an extraction result display screen shown in FIG. 5 and outputs it to the display unit 18.

The playback button 102 on the extraction condition setting screen 100 is a function to reproduce and display the history of disaster information from the past to the present. For example, when the user selects "Type 3 (red)", sets the playback target time from 10 o'clock yesterday to 10 o'clock today, and presses the play button 102, the extraction unit 13 Disaster information of “type 3 (red)” written on the medium 40 is extracted and output to the control unit 16. The control unit 16 displays a list of disaster information to which a red magnet was attached in the "type" column as of 10 o'clock yesterday. For example, the extraction unit 13 advances the clock every minute and extracts disaster information as of 10:01 yesterday. The control unit 16 displays a list of disaster information to which a red magnet was attached in the "type" column as of 10:01 yesterday. The extraction unit 13 and the control unit 16 sequentially repeat such processing, and detect changes in disaster information that have been marked with a red magnet in the “type” column of the medium 40 between 10 o’clock yesterday and 10 o’clock today. Reproduce.

(Display example of extraction results)
FIG. 5 is a first diagram showing an example of an extraction result display screen according to an embodiment of the present invention.
FIG. 5 shows the extraction results when the user selects "Type 3 (red)" as the type and makes no settings for the other "progress status" and "importance level." Each line in FIG. 5 corresponds to each line extracted from the information written on the medium 40. The "registration time" column in FIG. 5 displays the time when the first image taken by the camera 20 was registered after the disaster information was written on the whiteboard. In the "occurrence time" and "content" columns, the same information as the date and time and content of the extracted line in the medium 40 is displayed. The "type", "progress", and "importance" columns correspond to the colors of the magnets attached to the corresponding "type", "progress", and "importance" columns of the medium 40. Code information will be displayed. For example, if no magnet is attached, the value is "0", if a blue magnet is attached, it is "1", if a yellow magnet is attached, it is "2", and if a red magnet is attached, it is "3". ” information on each code is displayed.

Here, it is assumed that the yellow magnet in the "Importance" column is removed and a red magnet is attached to the disaster information on the fourth line in the left area of the medium 40 shown in FIG. Then, the image processing unit 12 detects a red magnet in the "Importance" column of the disaster information in the fourth row of the left area from the photographed image taken by the camera 20 at the next timing, and detects the "Importance" column of the attribute information. Set "3" to the "degree" value. The extraction unit 13 extracts rows in which "3" is set as the value of "type" in the attribute information. The control unit 16 generates an extraction result display screen 200 with the rows extracted by the extraction unit 13 as display targets. Unlike the display example in FIG. 5, the importance value in the second line of FIG. 5 is updated from "3" to "2".

Assume that the situation further progresses and that the fire response has been completed and the red magnet has been removed from the "Type" column regarding the disaster information on the fourth line in the left area of the medium 40 shown in FIG. Then, the image processing unit 12 detects from the image taken by the camera 20 that there is no magnet in the "type" column of the disaster information in the fourth row of the left area, and detects that there is no magnet in the "type" field of the disaster information. ” is set to “0”. Since the extraction unit 13 extracts the row in which “3” is set as the value of “type” in the attribute information, the disaster information in the second line in FIG. It is deleted from 200.
Note that the extraction result display screen 200 displays both the information written on the medium 40a and the information written on the medium 40b. Thereby, the information written separately on the plurality of media 40 is displayed in an integrated manner, thereby improving the visibility of the information.

FIG. 6 is a second diagram showing an example of an extraction result display screen according to an embodiment of the present invention.
The control unit 16 may generate an extraction result display screen 200' as illustrated in FIG. On the extraction result display screen 200', four areas are allocated for each type. In the area 201', a list of disaster information for which "0" is set in the "type" of the attribute information (those for which no magnet is attached in the "type" column of the medium 40) is displayed, and in the area 202', A list of disaster information (blue magnets) for which "type" of attribute information is set is displayed, and in area 203', disaster information (yellow magnet) for which "type" of attribute information is set to "2" is displayed. (Magnets) are displayed in a list, and in the area 204', disaster information (red magnets) whose "Type" of attribute information is set to "3" is displayed in a list. For example, the disaster information on the third and fourth lines in FIG. 2 is displayed in the lower right area 204'. Regarding the fire information in the fourth row of FIG. 2, when the fire response is finished and the red magnet is removed, the disaster information that was displayed in area 204' will be displayed in upper left area 201'. Become so.

(Example of registered data)
Next, an example of the data format stored in the storage unit 14 will be explained.
FIG. 7 is a diagram showing an example of a data table in an embodiment of the present invention.
The image processing unit 12 performs image processing on the latest captured image acquired by the image acquisition unit 11, and writes the result in a table 300 illustrated in FIG. 8. The table 300 includes “medium ID”, “line number”, “branch number”, “registration time”, “occurrence time”, “content”, “type”, “progress status”, “importance”, and “deletion flag”. ” has each item. Identification information of the medium 40 is stored in “medium ID”. For example, in the configuration example of FIG. 1, for disaster information written on the medium 40a (photographed image acquired from the camera 20a), the image processing unit 12 stores "1" in the "medium ID" item and writes it to the medium 40b. For the entered disaster information (photographed image obtained from the camera 20b), "2" is stored in the "medium ID" item. The image processing unit 12 stores in the "line number" item the line on which the disaster information is written on the medium 40. The image processing unit 12 stores a value obtained by adding 1 to the "branch number" item each time the attribute information changes. For example, when disaster information is written for the first time on the first line of the medium 40, the image processing unit 12 stores "1" in the "line number" and "0" in the "branch number" for that disaster information. do. Thereafter, when the attribute information changes (the magnet changes), the image processing unit 12 detects the change and generates a new line by adding 1 to the branch number. Information after the magnet has been replaced is registered in the new row. The "registration time" item stores the time when the disaster information in that row was registered in the table 300 (that is, the time when a change in attribute information was detected and a record with a new branch number was registered). The "occurrence time" item stores the image in the "date and time" column of the row that the image processing unit 12 cuts out from the photographed image. The "Contents" item stores the image in the "Contents" column of the row that the image processing unit 12 cuts out from the photographed image. The “type” item stores a value detected based on the “type” column of the relevant row of the photographed image. Specifically, the image processing unit 12 sets "0" in the "type" column of the medium 40 if no magnet is attached, "1" if a blue magnet is attached, and "1" if a yellow magnet is attached. If so, "2" is stored, and if a red magnet is attached, "3" is stored. The "progress status" item stores a value detected based on the "progress status" column of the relevant row of the photographed image. The "importance" item stores a value detected based on the "importance" column of the relevant row of the photographed image. The values that the image processing unit 12 stores in the "progress" item and the "importance" item are the same as in the case of the "type" item. The “erasure flag” item stores a value indicating whether the disaster information in the row has been erased from the medium 40. When the scale of a disaster is large and the amount of information is large, or when a disaster is prolonged, it may not be possible to write all the disaster information on the media 40a, 40b. In such a case, since the information written on the media 40a, 40b is stored in the information management device 10, the disaster information written on the media 40a, 40b is deleted. The deletion flag is set to "1" for the disaster information that has been deleted from the media 40a, 40b, and the deletion flag is set to "0" for the disaster information currently written on the media 40a, 40b. For example, if only ruled lines are detected from the latest photographed image obtained from the camera 20a, the image processing unit 12 sets “Erase Flag” in the “Erase Flag” field of the record in which “1” is stored in the “Medium ID” field. 1” is stored.
Furthermore, when the magnets attached to the "progress" columns of the media 40a and 40b are removed, the image processing unit 12 newly registers a record in which 1 is added to the maximum value of the registered branch number in the table 300. At the same time, the value "4" indicating the end of the disaster situation and the completion of the response is set in the "progress" item of that record.

(Editing deleted information)
FIG. 8 is a diagram showing an example of an update screen in an embodiment of the present invention.
Magnets can be replaced for disaster information written on the medium 40, but attributes cannot be changed for erased disaster information. The update screen 400 illustrated in FIG. 8 provides a function to change the values of "type", "progress", and "importance" for deleted disaster information. The user sets extraction conditions in the same manner as the extraction condition setting screen 100 illustrated in FIG. 4 . When the user presses the extraction button 401, a list of disaster information that satisfies the extraction conditions and has "1" stored in the deletion flag is displayed in the area 403. The values of "type", "progress", and "importance" in area 403 can be changed. For example, when the response to the disaster information displayed in the first line of FIG. 8 is completed, the user changes the type from "3" to "0" and presses the update button 402. Then, the control unit 16 updates the value of the "type" item of the corresponding record in the table 300 to "0". Thereby, the value of attribute information can be updated even for data erased from the medium 40.

(registration process)
Next, the registration process in the table illustrated in FIG. 9 will be explained.
FIG. 9 is a flowchart illustrating an example of registration processing in an embodiment of the present invention.
The person in charge manually inputs disaster information into the medium 40 using a pen. The camera 20 photographs the medium 40 at predetermined time intervals and outputs the images to the information management device 10.
In the information management device 10, the image acquisition unit 11 acquires a captured image of the medium 40 (step S11). The image acquisition unit 11 outputs the captured image to the image processing unit 12. The image processing unit 12 performs image processing on the photographed image (step S12). For example, the image processing unit 12 detects the ruled lines of the medium 40, determines the presence or absence of information written in each row and each column, and compares the determination result with the registered contents of the table 300 in FIG. 8. Alternatively, the image processing unit 12 may compare the previously acquired photographed image and the currently acquired photographed image. If there is a difference between the registered contents of the table 300, or if there is a difference between the previously acquired photographic image and the currently acquired photographic image, the image processing unit 12 extracts necessary information from the photographed image and table 300 (step S13). For example, when disaster information is entered for the first time in the first line of the left area of the medium 40, since no information is registered in the table 300 at that time, the image processing unit 12 writes the first line and Each column in the first row is recognized, and the information entered in the first row in the left area is registered in the table 300. The information to be registered in each item of "medium ID" to "erasure flag" is as described using FIG. 8.

For example, in the first line of the left area of the medium 40a, "10/1 15:10" is entered in the "Date and Time" column, "Fire Occurred in XX" is entered in the "Content" column, and a red magnet is written in the "Type" column. is attached and no magnet is attached to either "progress status" or "importance", the image processing unit 12 sets "1" to the "medium ID" item and "1" to the "line number" item. , "0" in the "branch number" item, the current time in the "registration time" item, an image with the "date and time" column cut out in the "occurrence time" item, an image with the "content" column cut out in the "content" item, A record is registered in the table 300 in which "3" is stored in the "type" item, "0" is stored in the "progress status" item, "0" is stored in the "importance" item, and "0" is stored in the "deletion flag" item.

Furthermore, when a magnet has been replaced, the image processing unit 12 recognizes the column where the magnet has been replaced based on the ruled line, and detects the presence or absence and color of the magnet after replacement. Then, the image processing unit 12 selects and duplicates the record with the largest branch number value among the records of the row in which the magnet has been replaced from the table 300, adds 1 to the branch number value, and replaces the magnet. A new record is registered in the table 300 in which any value from 0 to 3 is set in the item where the magnet was replaced, depending on the replaced magnet. For example, in the above example, if a blue magnet is newly added to the "progress status" column, the image processing unit 12 adds a new blue magnet to the "progress status" column using the ruled line as a guide from the latest captured image. Detects that a magnet has been attached, copies the record newly registered in the above process, sets "1" in the "branch number" item, "1" in the "progress status" item, and sets the same content for other items. A new record that has been left unchanged is registered in the table 300.
The image processing section 12 repeatedly performs the processes of steps S11 to S13 on a new photographed image every time the image acquisition section 11 acquires a photographed image.

(Display processing)
Next, display processing will be explained.
FIG. 10 is a flowchart illustrating an example of display processing in an embodiment of the present invention.
Data reflecting the latest state of the medium 40 is registered in the table 300 through the process described in FIG. 9 . First, the control unit 16 generates the extraction condition setting screen 100 shown in FIG. The output unit 17 displays the extraction condition setting screen 100 on the display unit 18 (step S21). The user sets extraction conditions for each item of "type", "progress status", "importance", and "deleted information". In addition, in the case of reproduction, a reproduction target time is set. The user presses the extract button 101 or the play button 102. Then, the input receiving unit 15 acquires the input extraction conditions and display mode (step S22), and outputs them to the control unit 16. The display mode is the latest mode that displays the latest disaster information, or the playback mode that reproduces changes in disaster information from the past. If the user presses the extract button 101, the mode is the latest mode, and if the user presses the play button 102, the mode is the playback mode. In the case of the latest mode (step S23; latest), the control unit 16 passes the extraction conditions to the extraction unit 13 and instructs extraction of disaster information that meets the conditions. The extraction unit 13 searches the table 300 using the extraction conditions. For example, if "Type 3 (red)", "Situation 3 (red)", "Importance level 3 (red)", and "Display" of the displayed information are selected on the extraction condition setting screen 100, the extraction section 13 retrieves from the table 300 the record with type = “3”, progress status = “3”, importance = “3”, deletion flag = “0” and “1”, and the branch number of each line number is the maximum value. Extract. The control unit 16 acquires the extraction result and generates an extraction result display screen 200 illustrated in FIG. 5 . The output unit 17 displays the extraction result display screen 200 on the display unit 18 (step S24). Even while the output unit 17 is displaying the extraction result display screen 200 on the display unit 18, the camera 20 photographs the medium 40 at predetermined time intervals and outputs the photographed images to the information management device 10. In the information management device 10, the image acquisition unit 11 acquires a photographed image, and if there is a change in the photographed image, the image processing unit 12 cuts out necessary information from the latest photographed image and stores it in the table 300. Register information (processing in FIG. 9). Furthermore, the control unit 16 updates the extraction result display screen 200 at predetermined time intervals. That is, the extraction unit 13 is instructed to perform extraction based on the above extraction conditions at predetermined time intervals, and the extraction results are received. Upon receiving the extraction result, the control unit 16 generates an extraction result display screen 200 displaying the extraction result and outputs it to the output unit 17 . The output unit 17 displays the latest extraction result display screen 200 on the display unit 18. Thereby, the information management device 10 extracts and displays only the necessary information from the latest disaster information.

In the case of playback mode (step S23; playback), the control unit 16 passes the extraction conditions and the playback target time (playback start time and playback end time) to the extraction unit 13, and extracts disaster information that meets the conditions in chronological order. Instruct to extract sequentially along the lines. The extraction unit 13 searches the table 300 using the extraction conditions. For example, if "Type 3 (red)", "Situation 3 (red)", "Importance level 3 (red)", and "Display" of the displayed information are selected on the extraction condition setting screen 100, the extraction section 13, first, type = “3”, progress status = “3”, importance = “3”, deletion flag = “0” and “1”, and for each line number, the registered time value is currently playing. The record with the maximum branch number before the time is extracted from the table 300. The extraction unit 13 advances a clock that manages the time during playback and extracts the latest information at a predetermined time interval measured by the clock. The extraction unit 13 outputs the extracted disaster information to the control unit 16. Each time the control unit 16 acquires an extraction result, it generates an extraction result display screen 200 and outputs it to the output unit 17. The extraction result display screen 200 may display the date and time during playback (time display column 201 in FIG. 5). The output unit 17 displays the extraction result display screen 200 on the display unit 18 (step S25). Even while the disaster information is being reproduced, the camera 20 photographs the medium 40 at predetermined time intervals and outputs the photographed images to the information management device 10. In the information management device 10, the image acquisition unit 11 acquires a photographed image, and the image processing unit 12 registers the information in the table 300 by cutting out necessary information from the latest photographed image as necessary (FIG. 9 processing). The control unit 16 reproduces the disaster information until the time during reproduction reaches the reproduction end time, regardless of the latest information. This makes it possible to extract only necessary information from past disaster information over a predetermined period of time and reproduce it in chronological order.

<Other Examples>
FIG. 11 is a second diagram showing an example of an information management system according to an embodiment of the present invention.
As shown in FIG. 11, the information management system 1A can be configured across multiple locations. Information management devices 10a to 10c, cameras 20a to 20c, and media 40a to 40c are installed at base 1, and cameras 20a, 20b, and 20c are installed for each of media 40a, 40b, and 40c. Cameras 20a, 20b, 20c are connected to information management devices 10a, 10b, 10c, respectively. Information management devices 10d to 10f, cameras 20d to 20f, and media 40d to 40f are installed at the base 2, and cameras 20d, 20e, and 20f are installed for each of the media 40d, 40e, and 40f. Cameras 20d, 20e, 20f are connected to information management devices 10d, 10e, 10f, respectively. The information management devices 10a to 10f can communicate with each other via a network. The information management device 10a has the same configuration as that shown in FIG. have. The same applies to the information management devices 10b to 10f. Then, for example, the information management device 10a of the base 1 is used as a master device to manage disaster information. That is, the information management device 10b transmits the image taken by the camera 20b to the information management device 10a. The information management devices 10c to 10f also transmit images taken by the cameras 20c to 20f connected to themselves to the information management device 10a. The information management device 10a acquires images taken by the cameras 20a to 20f, and performs the same processing as described above. For example, the extraction unit 13a extracts disaster information having attributes specified by the user, and the control unit 16a generates an extraction result display screen 200a displaying the extracted information. Further, the output unit 17a displays an extraction result display screen 200a on the display unit 18a. Further, the information management device 10a transmits the extracted information to the information management device 10d of the base 2, for example, and in the information management device 10d, the control unit 16d displays an extraction result display displaying the information received from the information management device 10a. A screen 200a is generated and displayed on the display section 18d. According to such a configuration, for example, regarding the disaster information displayed on the display sections 18a and 18d, the attribute information is updated on the media 40a to 40c of the base 1, or the attribute information is updated on the media 40d to 40f of the base 2. When updated, the results are reflected on the display on the display sections 18a and 18d. In other words, it becomes possible to share information in real time between multiple locations.

It is also possible to provide a master machine at each location. For example, at base 1, the information management device 1a is set as the master device, and at base 2, the information management device 1d is set as the master device. The information management devices 10a and 10d acquire captured images taken by the cameras 20a to 20f via the information management device 10 to which each camera 20 is connected. Then, the information management device 10a extracts and displays information necessary for the base 1 based on the operation of the user of the base 1. The extracted disaster information also includes information entered at base 2. The information management device 10d extracts and displays information necessary for the base 2 based on the operation of the user of the base 2. According to such a configuration, it is possible to grasp what kind of information is being received at other bases regarding the required disaster information.

FIG. 12 is a third diagram showing an example of an extraction result display screen according to an embodiment of the present invention.
FIG. 12 shows a display example when an information management system 1A is constructed across multiple locations. The extraction result display screen 200A displays more "base" information than the screen illustrated in FIG. 5 . For example, the disaster information on the first and third lines is the information written on the medium 40a of base 1, and the disaster information on the second and fourth lines is the information written on the medium 40d of base 2. be. Here, the disaster information in the first and second lines is information about the same disaster reported to base 1 and base 2, respectively, and written on the medium 40 of each base. In this example, both bases treat the type and progress the same, but the two bases have different judgments regarding importance. In such a case, the extraction result display screen 200A allows the two locations to recognize on the spot that different levels of importance have been determined, allowing them to reconcile their opinions and confirm each other's understanding. Additionally, the third and fourth lines contain information regarding the procurement of supplies needed in the disaster area.For example, base 1 plans to deliver supplies Y based on the manual as push-type support. Fill in the medium 40. On the other hand, base 2 near the disaster area hears that there are many requests for supplies Z from the field, and writes on the medium 40 that supplies Z are needed. Then, the person in charge at base 1 can understand that material Z is actually needed.
Note that when constructing the information management system 1A across multiple locations, additional locations may be selectable on the extraction condition setting screen 100 illustrated in FIG. 4 .
Further, in the above description, the output unit 17a outputs images on various screens to the display unit 18a, but the bases 1 and 2 are provided with a projector 30 and a screen 50, and the images are projected from the projector 30 onto the screen 50. You can.

(effect)
In an emergency, it is difficult to scrutinize the accuracy and importance of information and record only the necessary information. Furthermore, the importance and necessity of information change over time. Particularly in times of disaster, it is necessary to record information without leaking it even when there is little time to spare. On the other hand, since decisions must be made at disaster response headquarters, important information must be managed without being hidden. According to this embodiment, if only the date and time and contents are manually input into the medium 40, the camera 20 photographs the contents and the information management device 10 stores the information written on the medium 40, so that information leakage is less likely to occur. Become. Further, the person in charge can manually input data into the medium 40 without worrying about the upper limit of the amount of information that can be written on the medium 40. In addition, attribute information indicating the type, importance, necessity, etc. of manually input information can be entered in a simple way (attached with a magnet of a specified color), and the attribute information can be updated as the situation changes. Can be easily changed (replacement of magnet). With this method, there is no need to modify information once entered, so information can be easily managed even in an emergency, and it is easy to respond to changes in information attributes such as importance. be able to. In addition, since the time when information was written to the medium 40 and the history of changes to attribute information are all recorded, it is possible to keep a record of when and what kind of information was received and when the situation indicated by that information has been resolved. . Further, according to the present embodiment, only necessary information can be extracted and displayed based on attribute information. Therefore, visibility can be ensured even if the amount of information increases. Further, information can be shared by displaying the extracted information on the screens of multiple PCs or by projecting it onto the screen 50 using the projector 30. In addition, while it is difficult to uniformly evaluate the importance of information, it becomes possible to share information and participate in all parties involved to reach a consensus and make decisions. Furthermore, by switching the extraction conditions, it is possible to easily switch the information to be shared.
Further, once information is erased from the medium 40, it cannot be restored, but according to the information management device 10, the erased information is also saved, so the information can be checked even after the information is erased. Furthermore, since the recorded information can be reproduced arbitrarily even after a certain period of time has elapsed, it is possible to easily organize changes in chronological information. Further, although the person in charge of each organization often sees only the information that pertains to him or herself, by checking the list of disaster information displayed on the display unit 18, it is possible to get a bird's-eye view of the entire information.

<Information update support function>
In the above description, only the attribute information is changed without updating the disaster information written on the medium 40. However, disaster information may change over time. For example, when a flood occurs, the water level, water pressure, etc. may be written on the medium 40 and shared. In such a case, if each time the water level or water pressure changes, a new line of the medium 40 is used to record the changed water level or water pressure, a large number of lines would be required to write the information. If a large number of lines are required to write information, a large number of media 40 will be required, or information will be written on the back side of the media 40, which will impair the visibility of the information. Therefore, when it becomes necessary to update the disaster information, the information management device 10 is provided with a function that allows a person in charge to update the disaster information already written on the medium 40. Specifically, when the disaster information on the medium 40 is updated, the update is notified to the information management device 10 by the attachment of a magnet, and the information management device 10 records both the disaster information before and after the update. I'll keep it. By doing so, the latest disaster information or the history of past disaster information can be displayed on the display unit 18 or the screen 50 without leaving all the information on the medium 40.

13 and 14 are FIG. 1 and FIG. 2, respectively, showing an example of updating information in an embodiment of the present invention.
An example of the medium 40a' is shown in FIGS. 13 and 14. The difference from the medium 40 illustrated in FIG. 2 is that an "update" column is newly provided. "Update" is an area for attaching a magnet of a predetermined color when manually inputted information in "date and time" or "content" is updated. When the person in charge changes the "date and time" or the "content", the person in charge notifies the information management device 10 of the update of the disaster information by attaching a magnet to the "update" column. "Update" is one of the attribute information, like "type", "progress", and "importance". In the first line of the left area of the medium 40a shown in FIG. 13(a), "10/1 10:00" is entered in the "Date and Time" column, "X1 occurred, water depth Y1 cm" is entered in the "Content" column, A yellow magnet is attached to the "Type" column, a blue magnet is attached to the "Progress" column, and no magnet is attached to the "Importance" and "Update" columns. The person in charge inputs this information into the medium 40a' at 10:05 on October 1st.

After that, at 10:30, the person in charge updates the "Date and time" column to "10/1 10:20" and the "Contents" column to "X1 occurred, water depth Y2 cm", and attaches a magnet to the "Update" column. . The updated medium 40a' is shown in FIG. 13(b). When the person in charge attaches a magnet to the "Update" column, the image processing unit 12 detects the magnet from the photographed image, cuts out the image in the "Date and time" column and the image in the "Contents" column of the relevant row from the photographed image. , the updated disaster information is registered in the table 300 as a new record. For example, if the disaster information in this row is displayed on the extraction result display screen 200, the updated content will be displayed on the extraction result display screen 200. The person in charge recognizes that the information in the "date and time" column and the "content" column of the medium 40a' has been registered in the table 300 by updating the display on the extraction result display screen 200. After confirming that the updated disaster information has been registered in the information management system 1 (or after a predetermined period of time has passed after attaching the magnet to the "Confirmation" column), the person in charge removes the magnet from the "Update" column. . FIG. 13(c) shows the medium 40a' after removing the magnet. When the image processing unit 12 detects that a magnet has been attached to the "update" column, it registers the updated information in the table 300, but even if it detects that the magnet has been removed from the "update" column, the image processing section 12 registers the updated information in the table 300. 300 is not updated.

Next, refer to FIG. 14(a). After that, the situation changed again, and at 12:30, the person in charge updated the "Date and time" column to "10/1 12:20" and the "Contents" column to "X1 occurred, water depth Y3 cm", and the person in charge updated "Updated". ” Attach a magnet to the column. Additionally, the person in charge will change the color of the magnet in the ``progress status'' column to red as the disaster situation progresses. When the person in charge attaches a magnet to the "Update" column, the image processing unit 12 detects from the captured image that a magnet has been attached to the "Update" column, and extracts from the captured image the image in the "Date and Time" column of the corresponding row. The image in the "Contents" column is cut out and registered in the table 300 as a new record. The image processing unit 12 also detects that the magnet in the "progress status" column has changed from blue to red, and changes the value of the "progress status" item of the record newly registered in the table 300 from "1" to "1". Update to “3”. When the updated disaster information is registered in the table 300, the person in charge removes the magnet from the "update" column. FIG. 14(b) shows the medium 40a' after removing the magnet.

Afterwards, once the situation has subsided, the person in charge will remove the red magnet from the "progress" column at 15:00. FIG. 14(c) shows the medium 40a' after the magnet is removed. When the person in charge removes the magnet from the "progress status" column, the image processing unit 12 detects from the photographed image that the magnet has been removed from the "progress status" column, and adds a record with a new branch number to the table 300. , and set the value of the "progress" item of that record to "4" indicating completion. Thereafter, when the event is completed and the description in this line on the medium 40' is erased, the erasure flag of the corresponding record in the table 300 is set to "1" as described above. Thereafter, when new disaster information is manually input in the same row, the image processing unit 12 registers it in the table 300 as new disaster information (branch number=0).

A data registration process accompanying a change in information written on the medium 40a' illustrated in FIGS. 13 and 14 will be described.
FIG. 15 is a diagram showing an example of a data table in an embodiment of the present invention.
Compared to the table 300 illustrated in FIG. 7, the table 300' in FIG. 15 includes an "update count" item.
The record in the first row (branch number = 0) of the table 300' in FIG. 15 is data that is registered in the table 300' when the information written on the medium 40a' reaches the state shown in FIG. 13(a). It is. pic11 is an image extracted from the photographed image at "10/1 10:00", and pic12 is an image including "X1 occurred, water depth Y1 cm" from the photographed image. The image processing unit 12 stores "0" in the "number of updates" item. The method of registering data in other items of the table 300' is the same as that described using FIG. 7.

The record on the second line (branch number=1) is data that is registered in the table 300' immediately after the information written on the medium 40a' reaches the state shown in FIG. 13(b). Pic21 is an image extracted from the photographed image at "10/1 10:20", and pic22 is an image including "X1 occurred, water depth Y2 cm" from the photographed image. The image processing unit 12 sets "1" in the "number of updates" item.

The record in the third row (branch number=2) is data that is registered in the table 300' immediately after the information written on the medium 40a' reaches the state shown in FIG. 14(a). pic31 is an image extracted from the photographed image at "10/1 12:20", and pic32 is an image including "X1 occurred, water depth Y3 cm" from the photographed image. The image processing unit 12 sets "2" in the "number of updates" item.

The record on the fourth line (branch number=3) is data that is registered in the table 300' immediately after the information written on the medium 40a' reaches the state shown in FIG. 14(c). Since the red magnet is removed from the "progress status" column, "4" is registered in the "progress status" item.

Next, a display example of the extraction result display screen 200 in response to changes in the information written on the medium 40a' illustrated in FIGS. 13 and 14 will be shown.
16 and 17 are FIG. 4 and FIG. 5, respectively, showing an example of an extraction result display screen according to an embodiment of the present invention.
FIG. 16(a) shows the extraction result display screen 200 generated by the control unit 16 immediately after the entries shown in FIG. 13(a) are made and the record in the first row of FIG. 15 is registered in the table 300'. . The extraction condition set on the extraction condition setting screen 100 is, for example, "Type 1 (blue)". FIG. 16(b) shows the extraction result display screen 200 generated by the control unit 16 immediately after the record in the second line of FIG. 15 is registered in the table 300'. FIG. 16(c) shows the extraction result display screen 200 generated by the control unit 16 immediately after the record in the third row of FIG. 15 is registered in the table 300'. When generating the extraction result display screen 200, the control unit 16 refers to the value of the “number of updates” item of the data extracted by the extraction unit 13. If the value of the "number of updates" item is 1 or more, the control unit 16 generates an extraction result display screen 200 that displays a plus button 210 in the "content" column of the data, for example. When the user clicks the plus button 210, the update history is displayed on the extraction result display screen 200. FIG. 17 shows an example of the extraction result display screen 200 on which the update history is displayed. In the extraction result display screen 200 illustrated in FIG. 17, the contents displayed in FIGS. 16(a) to 16(c) are displayed in chronological order. A minus button 210' is displayed in the "content" column of the data whose history is displayed on the extraction result display screen 200. When the minus button 210' is clicked, the extraction result display screen 200 returns to the display mode shown in FIG. 16(c).

Further, when the user clicks the plus button 210, the control unit 16 may generate a history display screen 220 illustrated in FIG. 18. FIG. 18 is a diagram showing an example of a history display screen in an embodiment of the present invention. As illustrated, past history is displayed on the history display screen 220.

In this way, according to the information update support function, even if the information manually input to the medium 40a' is updated by simply attaching or removing the magnet to the "update" column of the medium 40a', the information before and after the update will be updated. can be recorded. This eliminates the need to always record all information on the medium 40a', eliminates information dissipation, and ensures visibility of information. Further, the latest information can be displayed on the display unit 18 and screen 50. In addition, you can display the update history of the information by simply clicking the plus button 210 displayed for the disaster information you want to refer to, so you can easily check the past historical data and understand the trends in the disaster situation. I can do it. This enables information management that flexibly responds to changes in disaster conditions.

<Refresh function>
The medium 40, on which information can be written on both sides, may be a whiteboard. When writing information on the front side of the medium 40a and transferring information to the back side, the user specifies the medium 40a and performs a predetermined operation (refresh operation) on the information management device 10. Then, the image processing unit 12 recognizes that the medium 40a being photographed by the camera 20a has been replaced, and changes the information manually input in the first line of the back side to, for example, medium ID="1'", line It is registered in the table 300' as number = "1", branch number = "0", and so on. Then, when the surface of the medium 40a becomes the object of writing/updating again and a refresh operation is performed, the image processing unit 12 sets the record of medium ID="1" in the table 300' as the object of registration/update.
