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

摘要

A tracking assistance device includes: a target-to-be-tracked setting unit that, in response to an input operation performed by a monitoring person on one of display views to designate a moving object to be tracked, sets the designated moving object as a target to be tracked, the display views displaying captured images taken by respective cameras and stored in a recorder; a camera selection unit that, based on tracing information obtained by processing the captured images, selects any of the cameras inferred to have taken an image of the moving object designated as the target to be tracked from among the cameras other than the camera corresponding to the display view on which the target to be tracked was designated; and a playback unit that causes the captured images taken by each camera selected by the camera selection unit to be displayed in a corresponding one of the display views.

主权项

1. A tracking assistance device for assisting a monitoring person in performing a task of tracking a moving object to be tracked, by displaying a screen on a display device, the screen including a plurality of display views displaying captured images taken by respective cameras and stored in an image storage, the plurality of display views being arranged on a map image representing a monitored area in accordance with an actual arrangement of the cameras, the tracking assistance device comprising:
a target-to-be-tracked setter that causes the captured images stored in the image storage to be displayed in the plurality of display views in accordance with a specified search condition, including a capture time, and, in response to an input operation performed by the monitoring person on one of the plurality of display views to designate a moving object to be tracked, sets the designated moving object as a target to be tracked; a camera selector that, based on tracing information obtained by processing the captured images, selects at least one camera inferred to have taken an image of the moving object designated as the target to be tracked, from the cameras other than a camera corresponding to the display view on which the target to be tracked was designated; a confirmation image presenter that extracts a confirmation image, based on the tracing information relating to the moving object set as the target to be tracked, from the captured images taken by each of the at least one camera selected by the camera selector, and causes the display device to display a target-to-be-tracked confirmation screen including the confirmation image, the confirmation image comprising a captured image taken by each of the at least one camera selected by the camera selector when tracing of the moving object started and supposed to include the moving object; and a playback device that performs a continuous playback in which the captured images from which the confirmation image is extracted by the confirmation image presenter are displayed in the plurality of display views sequentially along with passage of time.
