Tracking assistance device, tracking assistance system and tracking assistance method

摘要

A tracking assistance device for assisting a monitoring person in tracking a moving object by displaying on a display device a monitoring screen in which display views for displaying in real time captured images taken by respective cameras are arranged on a map image representing a monitored area in accordance with an actual arrangement of the cameras, includes: a target-to-be-tracked setting unit that, in response to an input operation performed by the monitoring person on one of the display views to designate a moving object to be tracked, sets the designated moving object as a target to be tracked; a prediction unit that predicts a next display view in which the moving object set as the target to be tracked will appear next based on tracing information obtained by processing the captured images; and a display view indicating unit that indicates the next display view on the monitoring screen.

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 monitoring screen on a display device, the monitoring screen including a plurality of display views displaying in real time captured images taken by respective cameras, the plurality of display views 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, 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 target-to-be-tracked indicator that, based on tracing information obtained by processing the captured images, indicates the moving object set as the target to be tracked in each of the plurality of display views in which the moving object set as the target to be tracked appears; a predictor that predicts a next display view in which the moving object set as the target to be tracked will next appear based on the tracing information; and a display view indicator that indicates the next display view predicted by the predictor on the monitoring screen, wherein the target-to-be-tracked indicator provides first highlighting to highlight a moving object frame associated with the moving object set as the target to be tracked and the display view indicator provides second highlighting to highlight a display frame associated with the next display view predicted by the predictor.
