  Here, the controller 301 of the person tracking system enters / exits history information with the card number (00100048), date (May 12, 2006), time (14:02:53), and door identification number (IV). 2 is acquired.

  The control unit 301 acquires the video history information 2 that matches the date (May 12, 2006), time (14:02:53), and door identification number (IV) information included in the entry / exit history information 2. To do.

  The control unit 301 associates the card number, the video information, the door identification number, the date, and the time from the acquired entrance / exit history information 2 and the video history information 2 as the tracking history information 2 and associates it with the tracking history information 1 and stores the storage unit Record in 303.

  Then, as shown in FIG. 7, the control unit 301 uses the card number (00100048), the date (May 12, 2006), the time (14:02:53), the door identification number (IV) as the tracking history information 2. The video information is displayed on the display unit 305 along with the tracking history information 1.

  Next, from the door arrangement information shown in FIG. 6 recorded in the storage unit 303, the control unit 301 determines that the person who was in the room A at the time of occurrence of the abnormality is a door that passed before the time that passed through the door IV. Judge that it is not passing through other than door II.

  Then, the control unit 301 uses the IC card having the card number 00100048 to obtain the input acquired by the reader / writer provided in the door II before the time when the door IV is unlocked (14:02:53). Get exit history information.

  In this case, the control unit 301 of the person tracking system acquires the entry / exit history information that matches the door identification number (II), the card number (00100048), and the time (before 14:02:53).

  Here, the control unit 301 of the person tracking system uses the card number (00100048), date (May 12, 2006), time (14:02:17), and door entry / exit information 3 as the door identification number (II). Is obtained.

  The control unit 301 includes video history information including a video index that matches the date (May 12, 2006), time (14:02:17), and door identification number (II) information included in the entry / exit information 3. Get 3.

  The control unit 301 associates the card number, the video information, the door identification number, the date, and the time from the acquired entrance / exit history information 3 and the video history information 3 into the tracking history information 3 as tracking history information 1 and tracking history information 2. And is recorded in the storage unit 303.

  Then, as shown in FIG. 7, the control unit 301 uses the card number (00100048), date (May 12, 2006), time (14:02:17), door identification number (II) as the tracking history information 3. The video information is displayed on the display unit 305 side by side with the tracking history information 1 and the tracking history information 2.

  As described above, the person tracking system obtains detailed tracking history information by going back in time as to what route the person corresponding to the card number 00100048 who entered the room A at the time of occurrence of the abnormality entered the room A. can do. Also, since the time of passing through each door as well as the entrance / exit route to room A can be easily determined, it is possible to calculate where and how long the user has stayed. Further, when the abnormality occurrence time is set with a width, an entrance / exit route to the room A can be acquired for each person who enters the room A.

  In the present embodiment, the entry / exit history information is acquired from the entry / exit history index using the time and the card number, but by using the door arrangement information shown in FIG. 6, the entry / exit history information passes immediately before passing through a specific door. Since it is possible to exclude door numbers that are unlikely, the person tracking system can easily acquire the desired entry / exit history information without applying a load.

The above flow will be described with reference to the flowchart shown in FIG. First, an abnormality occurrence time is set by the input unit 304 of the person tracking system (step S101).
The control unit 301 of the person tracking system enters / exits history information in which the card number, date, time, and door identification number that have passed through the entry / exit door necessary for entering a specific room from the entry / exit management system are associated with each other. Is acquired (step S102).

  Next, the control unit 301 of the person tracking system acquires from the video system video history information that matches the date, time, and door identification number information included in the acquired entry / exit history information (step S103).

  The control unit 301 of the person tracking system determines the door identification number subordinate to the door identification number included in the acquired entry / exit history information from the door arrangement information recorded in the storage unit 303 (step S104). If there is no subordinate door identification number (step S104, NO), the control unit 301 displays all of the tracking history information in which the acquired room entry / exit history information and the video history information are associated with each other in the display unit 305 in chronological order. (Step S105).

  If there is a subordinate door identification number (step S104, YES), the control unit 301 will enter / exit the entry / exit history that passed through any subordinate door identification number before the time included in the acquired entry / exit history information. Information is newly acquired (step S106).

  Then, the control unit 301 of the person tracking system returns to step S103, and acquires video history information that matches the date, time, and door identification number information included in the newly acquired entry / exit history information (step S103).

In the above description, the system for tracking a person who has entered and exited the room A has been described. However, when a person who has entered and exited a specific room is to be tracked, the controller 301 can enter the room by inputting the room using the input unit 304. It is also possible to obtain the door identification number associated with the provided door in advance and track the intrusion route of the person who entered and exited for all rooms. Here, a reader / writer and a photographing unit were provided at the entrance of the entrance door. Although the example has been described, the same applies to the case where reader / writers and photographing units are provided at both the entrance and exit of the entrance door.

  Next, a second embodiment will be described with reference to FIGS. Here, it is a monitoring setting for tracking which route a specific person moves and where he / she is currently at night or at the time of warning requiring monitoring such as VIP.

  FIG. 9 is a diagram showing a flow of person tracking at the time of monitoring setting. FIG. 10 is a diagram showing a display of information acquired by the person tracking system.

  When the control unit 301 of the person tracking system receives an input of the monitoring setting at the input unit 304 or a trigger for the monitoring setting ON from the entrance / exit management system connected via the network via the network interface 302, the tracking processing is performed. Start. The monitoring setting is started by inputting the card number of the IC card held by the person to be monitored, for example, through the input unit 304. Alternatively, a person who uses an IC card with a reader / writer provided at a specific door (card number used) can be set as a monitoring target.

  The entrance / exit management system, when a person passes an entrance / exit door by placing an IC card on a reader / writer provided near the entrance / exit door, enters / exits history information that correlates the card number, door identification number, date, and time. It is recorded as an entry / exit history list. Further, the video system records video history information in which a person who has passed through the entrance door is photographed, video history information in which the unlocked door identification number, date, and time are associated with each other as a video history list.

  Here, a case where the tracking process is set for the person X (corresponding card number) will be described. The example shown in FIG. 4 is used for the signs of the door and the room. For example, when the person X passes through the door 1 (Gate 1) and enters the room B, the entrance / exit management system stores the card number, door identification number, date, time, and entry permission test result in the storage unit 105 in one record. Record as entry / exit history information. Further, in the image system, when the door is unlocked, the control unit 206 uses the video information captured by the imaging unit capturing the user entering the room as video history information together with the door identification number, date, and time. Record in the storage unit 207.

  The control unit 301 of the person tracking system acquires the entry / exit history information of the card number input by the input unit 304 from the entry / exit index.

  In order to obtain the corresponding entry / exit history information, the control unit 301 of the person tracking system transmits a condition (here, the entered card number and time) via the network interface 302, and the control unit 107 of the entry / exit management system. Is searched for entry / exit history information matching the conditions from the entry / exit history list recorded in the storage unit 108. And the control part 107 of an entrance / exit management system transmits to a person tracking system via the network interface 109. FIG. Further, as shown in FIG. 5, the control unit 301 acquires the entry / exit index of the entry / exit history information included in all the entry / exit history lists from the entry / exit management system, records it in the storage unit 303, and inputs the card An entrance / exit index of the entrance / exit history information associated with the number and time can also be acquired.

  Then, the video history information matching the door identification number, date, and time included in the entry / exit history information is acquired from the image index.

  For acquisition of the corresponding video history information, the control unit 301 of the person tracking system transmits the conditions (here, date, time, door identification number) via the network interface 302, and the control unit 206 of the video system stores it. The video history information matching the conditions is searched from the video history list recorded in the unit 207. Then, the control unit 206 of the video system transmits to the person tracking system via the network interface 208. Further, as shown in FIG. 5, the control unit 301 acquires the video index of the video history information included in all video history lists from the video system, records it in the storage unit 303, and is included in the acquired entrance / exit information. It is also possible to obtain an entrance / exit index of video history information that matches the conditions (date, time, door identification number).

  Then, the control unit 301 associates the acquired entry / exit history information with the video history information and records them in the storage unit 303 as tracking history information.

  Then, as shown in FIG. 10, the control unit 301 shows the door identification number passed as tracking history information, the date and time passed, and video information on the display unit 305.

  Next, the control unit 301 of the person tracking system determines that the person X is in the room B, and the person X is provided in the doors I, III, IV, and V based on the door arrangement information shown in FIG. It is determined to move using the reader / writer. Here, an example will be described in which a reader / writer and an imaging unit are provided at both the entrance and exit of the entrance door, but the same applies to the case where the reader / writer and the imaging unit are provided only at the entrance of the entrance door.

  Therefore, when the person X passes through the doors I, III, IV, and V, the control unit 301 of the person tracking system performs the doors I, III, IV, and V after the time included in the acquired entry / exit history information. The movement of the person X can be traced by determining whether or not the card number has been used. If no door passes through the door, it is determined that the person X is staying in the room, and the control unit 301 counts the time as the staying time from the time included in the tracking history information (the time when the user enters the room). be able to.

  As described above, the control unit 301 acquires the entry / exit history information and the video history information each time the monitoring target moves and passes through the door, and creates tracking history information.

  By using the door arrangement information, even when a large number of doors are provided, the number of doors subordinate to one door is limited. Therefore, the control unit 301 of the person tracking system is recorded in the entrance / exit management system. Since the number of search objects for searching for the corresponding entry / exit history information from the entrance / exit history information of is reduced, it can be easily obtained without imposing a load on the system. Further, the control unit 301 of the person tracking system acquires the video history information based on the relationship between the door identification number specified from the video index and the time, so that the number of search targets is reduced, which places a load on the system. It can be easily obtained without.

  As shown in FIG. 10, the control unit 301 displays the tracking history information recorded in the storage unit 303 for each person along the time series moved to the display unit 304, and displays the current stay location and stay time. To do. In this case, the monitoring target is a person X and a person Y.

  Since the control unit 301 knows the door that passed through last time (in the case of the person X in FIG. 10, the door 5), the person X stays in a room (room A) that passes through the door 5 as a staying place. A message is displayed. Moreover, the staying time staying in the room A which finally passes through the door is counted and displayed in real time. When the person tracking system acquires new entry / exit history information due to the person X passing through another door, the control unit 301 resets the counter.

  As described above, since the tracking information is displayed side by side every time the monitoring target passes through the door, the movement route of the monitoring target can be easily grasped, and it can be easily grasped where the person is currently staying.

In addition, image data such as the entrance / exit management ID (card number) and the face of the owner of the IC card having the ID are stored as ID information in the storage unit 303 of the person tracking system, and the control unit 301 acquires the tracking information. It is also possible to determine whether or not the IC card is illegally used by a third party by comparing the history and the image data of the ID information. The present invention is limited to the above-described embodiment. However, the present or future implementation stage can be variously modified based on the technology available at that time without departing from the scope of the invention. In addition, the embodiments may be appropriately combined as much as possible, and in that case, the combined effect can be obtained. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some configuration requirements are deleted from all the configuration requirements shown in the embodiment, a configuration from which these configuration requirements are deleted can be extracted as an invention.
