FIG. 8 is a flowchart showing the main part of the processing contents of the monitoring apparatus according to Embodiment 1 of the present invention.

Next, the operation will be described.
When the monitoring device is activated, the map display processing unit 1 displays a map indicating the monitoring target area on the monitor 2.
FIG. 9 is an explanatory diagram showing a display example of a screen showing a monitoring target area, a monitoring video, an authentication list, and the like.
In the example of FIG. 9, a map of the conference floor A_3F that is the monitoring target area is displayed, and five rooms in the conference floor A_3F are areas where access is restricted.
In addition, about 20 cameras 3 are installed on the conference floor A_3F. Although not shown in FIG. 9, the doors installed at the entrances and exits of each room are provided with electric locks. An identification information acquisition unit 10 is installed in the vicinity.

In the example of FIG. 9, in addition to the conference floor A_3F, there are a plurality of monitoring target areas (for example, floors 1F, 2F, 4F, 5F, 6F, and 7F), and the selection area of the monitoring target area on the screen is a map. A plurality of monitoring target areas that can be displayed are shown.
In the example of FIG. 9, the map of the conference floor A_3F is displayed. However, if the user selects the floor 5F using a man-machine interface such as a mouse, the map of the floor 5F is displayed.

The cameras 3 are installed at a plurality of locations in the monitoring target area, and output monitoring images of the installation locations.
The camera video acquisition unit 4 acquires the monitoring video output from the plurality of cameras 3 and stores the monitoring video together with the camera number indicating the camera 3 in the camera video storage unit 5.

The monitoring target person detection unit 6 analyzes the monitoring video (live video) acquired by the camera video acquisition unit 4 and performs a process of detecting a person (monitoring target person) existing in the monitoring video. .
Since the person detection process itself is a known technique, a detailed description thereof will be omitted. For example, a person can be detected by pattern recognition of a human face or the like.
When there is a monitoring target person in the monitoring video acquired by the camera video acquisition unit 4, the monitoring target person detection unit 6 performs icon display processing of the camera number indicating the camera 3 photographing the monitoring target person. Output to unit 7.

When the icon display processing unit 7 receives the camera number indicating the camera 3 photographing the monitoring subject from the monitoring subject detection unit 6, the icon display processing unit 7 refers to the camera / door table of FIG. 4 stored in the table storage unit 11. Then, the photographing area of the camera 3 indicated by the camera number is recognized. For example, if the camera number is “K0013”, it is recognized that the shooting area of the camera 3 is in the second floor 03 conference room.
When the icon display processing unit 7 recognizes the shooting area of the camera 3 indicated by the camera number, the icon display processing unit 7 outputs a command to the map display processing unit 1 to display the icon of the monitoring subject at a position in the shooting area of the camera 3.
Thereby, the map display processing unit 1 displays the icon of the monitoring target person at a position in the shooting area of the camera in the map indicating the monitoring target area.
In the example of FIG. 9, the icon of the monitoring subject is displayed in the lower right room.

Further, the icon display processing unit 7 refers to the camera / door table of FIG. 4 stored in the table storage unit 11 to recognize all the cameras 3 installed in the monitoring target region, and to monitor the monitoring target region. A command to display the icons of all the cameras 3 installed in the map on the map is output to the map display processing unit 1.
Thereby, the map display processing unit 1 displays the icon of the camera 3 on the map indicating the monitoring target area.
In the example of FIG. 9, the icons of about 20 cameras 3 are displayed.

The monitoring target person selecting unit 8 specifies the monitoring target person by receiving selection of one of the icons of one or more monitoring target persons displayed on the map indicating the monitoring target area.
That is, when the user selects one of the icons of one or more monitoring subjects displayed on the map, the selection result of the icon is output to the video display processing unit 9 and the prediction processing unit 16. .
In the example of FIG. 9, only one icon of the monitoring target person is displayed. However, if a plurality of persons are present in the monitoring target area, a plurality of icons are displayed. The icon of the person to be monitored can be selected.

When the video display processing unit 9 receives the icon selection result from the monitoring target person selecting unit 8, the video display processing unit 9 captures the monitoring target person related to the selected icon from the monitoring video stored in the camera video storage unit 5. A monitoring video (for example, a LIVE video) of the camera 3 is acquired.
When the video display processing unit 9 acquires the monitoring video of the camera 3, as shown in FIG. 9, the video display processing unit 9 displays the monitoring video of the camera 3 on the same screen as the map indicating the monitoring target area.
In the example of FIG. 9, the LIVE video of the camera 3 is displayed on the upper right of the screen. However, if the “History” tab is selected on the monitoring video, the LIVE video is changed to the past monitoring video by the camera 3. Can be switched.
If the “authentication” tab on the monitoring video is selected, the person to be monitored is authenticated (identification information is acquired by the identification information acquisition unit 10 described later, and the permitted entry person is determined by the permitted entry determination unit 12). It is possible to switch to the video during the process of receiving the determination of whether or not.

The identification information acquisition unit 10 is installed for each area where entry is restricted within the monitoring target area. For example, in the case where the identification information acquiring unit 10 includes a card reader, from the IC card held by the monitoring target person, As the identification information of the monitoring subject, the tag number and the ID number of the monitoring subject are read (step ST1 in FIG. 8).
For example, when a monitoring target who wishes to enter a room where entry is restricted holds the IC card over the card reader, the card reader reads the tag number and ID number stored in the IC card.
For example, when the identification information acquisition unit 10 is composed of a biometric authentication device, the fingerprint or eyeprint of the monitoring subject is read as the identification information of the monitoring subject.

When the identification information acquisition unit 10 reads the identification information (tag number, ID number) of the monitoring target person, the permitted entry determination unit 12 reads from the tag / personal information table of FIG. 2 stored in the table storage unit 11. The security level of the monitoring subject corresponding to the identification information (tag number, ID number) is read, and the security level of the area where the identification information acquisition unit 10 is installed is entered from the access restriction area table of FIG. Reading is performed (step ST2).
For example, if the tag number is “1000” and the ID number is “0001”, “B” is read as the security level of the monitoring subject, and the identification information (tag number, ID number) of the monitoring subject is read. If the area where the identification information acquisition unit 10 is installed is “FK0004”, “B” is read as the security level of the area.
When the monitoring subject's fingerprint or eyeprint is read as the monitoring subject's identification information, the monitoring subject corresponding to the monitoring subject's fingerprint or eyeprint is referred to by referring to a table (not shown). Read the security level.

The permitted entry determination unit 12 reads the security level of the monitoring target person and the security level of the area, and compares the security level of the monitoring target person with the security level of the area (step ST3).
If the security level of the person to be monitored is higher than the security level of the area (including the case where the security level is equivalent), the person to be permitted to enter is permitted to enter the area. It is determined that the person is a permitted entry person (step ST4).
For example, when the security level is “A”, “B”, and “C”, and the security level of the monitoring subject is “B”, the security level of the area is “B” and “C”. In some cases, it is determined that the person to be monitored is a permitted entry person.

If the security level of the person to be monitored does not satisfy the security level of the area, the person permitted to enter 12 determines that the person to be monitored is not an authorized person (step ST5).
For example, if the security level of the monitoring target person is “B”, if the security level of the area is “A”, it is determined that the monitoring target person is not a permitted entry person.

The key control unit 13 refers to the authentication device / electric lock table of FIG. 6 stored in the table storage unit 11 when the entry permitter determination unit 12 determines that the person to be monitored is an entry permitter. Then, the electric lock number corresponding to the authentication device number indicating the identification information acquisition unit 10 (authentication device) that has read the identification information (tag number, ID number) of the monitoring subject is read.
Then, the key control unit 13 unlocks the electric lock by transmitting a control signal instructing unlocking to the electric lock indicated by the electric lock number (step ST6).
On the other hand, when the entry permitter determination unit 12 determines that the person to be monitored is not an entry permitter, the key control unit 13 keeps the electric lock closed in order to maintain the electric lock closed. On the other hand, a control signal for instructing unlocking is not transmitted (step ST7).

The action history record processing unit 14 refers to the tag / personal information table of FIG. 2 stored in the table storage unit 11 and corresponds to the identification information (tag number, ID number) acquired by the identification information acquisition unit 10. The area number indicating the area where the identification information acquisition unit 10 is installed (the area where the person to be monitored is visiting) with reference to the access restriction area table of FIG. And the security level of the area is read out, and as shown in FIG. 7, the action history for each person to be monitored is recorded in the history database 15 (step ST8).
For example, when the tag number is “10003” and the ID number of the monitoring subject is “0004”, “B” is read as the security level of the monitoring subject.
If the area visited by the person being monitored is “F0101”, “Room 01 on the first floor” is read as the room number, and “B” is read as the security level of the area.

In the example of FIG. 7, the action history of the monitoring target person with the tag number “10003”, the ID number “0004”, and the security level “B” is shown. Area number indicating the area visited by the person (the area where the identification information acquisition unit 10 is installed), the room number indicating the room corresponding to the area, the security level of the area, and the determination time of the permitter determination unit 12 (In the case of entry OK, the entry time and exit time, and in the case of entry NG, the entry refusal time) and the determination result (entrance OK or entry NG) of the entry permitter determination unit 12 are recorded in the history database 15.
Note that the behavior history for each person to be monitored is managed, for example, in units of one day, and the behavior history on December 29, 2010 is shown in the example of FIG.

The prediction processing unit 16 refers to the past behavior history recorded in the history database 15 and refers to an area where the monitoring target indicated by the identification information acquired by the identification information acquisition unit 10 is likely to come next. Predict.
That is, the prediction processing unit 16 selects the monitoring target person (designated by the user) indicated by the selection result output from the monitoring target person selecting unit 8 from the action history for each monitoring target person recorded in the history database 15. The action history of the person to be monitored is read (step ST9).
For example, when the action history of the period from September 1, 2010 to today is recorded in the history database 15, all the action histories of the monitoring target person in that period are read.

When the prediction processing unit 16 reads the behavior history of the selected monitoring target person, the prediction processing unit 16 refers to today's behavior history of the monitoring target person and refers to the area number (the latest Confirm the area number corresponding to the entry time or entry refusal time) and the area number (area number corresponding to the second new entry time or entry refusal time) that indicates the area that the monitored person has visited immediately before (Step ST10).
When the prediction processing unit 16 confirms the area where the monitoring target person is currently visiting and the area visited immediately before, the prediction processing unit 16 is the area where the monitoring target person is currently visiting from the daily action history in the above period. A series of action histories in which the area visited immediately before is the same and the area visited next is recorded are searched (step ST11).
For example, if the area visited by the person to be monitored is “2nd floor 03 meeting room” and the currently visited area is “1st floor room 02”, the “2nd floor A search is made for a series of action histories in which it is recorded that the user has visited “Room 03 Room” after visiting “03 Conference Room” and then visited another area.
Here, for convenience of explanation, it is assumed that a series of M action histories have been searched.

When the prediction processing unit 16 searches for a series of M action histories, the prediction history unit 16 groups the action histories in the same area where the monitoring target person next visits (step ST12).
For example, when the area where the monitoring target person next visits is classified into three, it is classified into three groups.
The prediction processing unit 16 counts the number of times the area has been visited in the past (the number of action histories belonging to the group) for each group, and determines whether the number is N times or more ( Step ST13). N times is a preset number (N is an integer equal to or greater than 1), and the user can change it as necessary.

The prediction processing unit 16 predicts an area where the number of visits in the past is N or more as an area where the monitoring target person is likely to visit next (step ST14).
For example, when the number of action histories belonging to group 1 is 3, the number of action histories belonging to group 2 is 8, and the number of action histories belonging to group 3 is 7, if N = 5, then group 2 and group 3 Two areas indicated by the action history belonging to are predicted as areas where the monitoring target person is likely to visit next.
Here, the prediction processing unit 16 shows a search for a series of action histories in which the area currently visited by the monitoring target person is the same as the area visited immediately before. A series of action histories having the same visited area before the area may be searched.

When the prediction processing unit 16 predicts a region that is likely to be visited next by the prediction processing unit 16, the prediction region specifying unit 17 displays the region predicted by the prediction processing unit 16 on the map representing the monitoring target region. An explicit command is output to the map display processing unit 1.
Thereby, as shown in FIG. 10, the map display process part 1 specifies the area where the said monitoring subject is highly likely to come next on the map showing the monitoring target area (step ST15).
In the example of FIG. 10, the monitoring target person in the area of the area number “FK0015” (the room at the lower right in the figure) is likely to visit next, the area of the area number “FK0011” and the area number “ The area of “FK0012” is clearly indicated.
In FIG. 10, in the past action history, the number of times of next visit is greater in the area of the area number “FK0011” than in the area of the area number “FK0012”. It is clearly designated as the most likely area to visit.

  The authentication list display processing unit 18 includes the identification information (the ID number of the person to be monitored) acquired by the identification information acquisition unit 10, the determination time / determination result (authentication result) of the entry permitter determination unit 12, and the state of the door key An authentication list indicating (a control result by the key control unit 13) is generated, and the authentication list is displayed on the same screen as the map representing the monitoring target area, as shown in FIG.

  As is apparent from the above, according to the first embodiment, the identification information of the monitoring subject that is installed in each area where entry is restricted within the monitoring target area and desires to enter the area.
