Tracking assistance device, tracking assistance system, and tracking assistance method

A tracking assistance device that displays on a display device, a video from each of a plurality of cameras which is accumulated in video accumulator and assists a monitoring person's work of tracking a moving object which is a tracking target, the device comprising:

• a confirmation video presentor that extracts for each of the cameras, a video of a moving object having a highest possibility of being the moving object set as the tracking target, based on tracking information acquired in a tracking process executed on the videos accumulated in the video accumulator, and displays on the display device, a tracking target confirmation screen in which only the extracted videos are displayed as confirmation videos;
• a video display period setter that displays a tracking result editing screen on the display device in a case where there is excess or deficiency in the confirmation video for each camera displayed on the tracking target confirmation screen, and sets a video display period during which a moving object set as the tracking target appears in a video, in response to a user's operation input on the tracking result editing screen;
• and
• a tracking information corrector that corrects the tracking information so as to display the confirmation video on the tracking target confirmation screen based on the video display period.

A tracking assistance system that displays on a display device, a video from each of a plurality of cameras which is accumulated in video accumulator and assists a monitoring person's work of tracking a moving object which is a tracking target, the system comprising:

• the camera that captures an image of a monitoring area;
• the display device that displays a video from each of the cameras;
• and
• a plurality of information processing devices,
• wherein one of the plurality of information processing devices includes
• a search condition setter that sets a search condition for finding out a video of the moving object which is a tracking target, in response to a user's operation input;
• a tracking target setter that acquires a video conforming to the search condition from the video accumulator to display a tracking target search screen on the display device, and in response to a monitoring person's operation input of designating the moving object which is the tracking target, by an operation of selecting a tracking mark displayed on the video on the tracking target search screen, sets the designated moving object as the tracking target;
• a confirmation video presentor that extracts for each of the cameras, a video of a moving object having a highest possibility of being the moving object set as the tracking target, based on tracking information acquired in a tracking process executed on the videos accumulated in the video accumulator, and displays on the display device, a tracking target confirmation screen in which only the extracted videos are displayed as confirmation videos;
• a video display period setter that in a case where the tracking mark is not displayed on the moving object which is the tracking target on the tracking target search screen, sets a video display period during which the moving object which is set as the tracking target appears in the video, in response to the user's operation input;
• and
• a tracking information corrector that corrects the tracking information so as to display the confirmation video on the tracking target confirmation screen based on the video display period.
