TARGET TRACKING DEVICE, TARGET OBSERVATION SYSTEM, TARGET TRACKING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To achieve correlation processing capable of correctly identifying targets even when the overlapped targets are separated after a plurality of the targets are overlapped to be observed as one target and the plurality of the targets are observed again.;SOLUTION: An overlapping determining device 115 judges whether the plurality of the targets are observed as one target by being overlapped. An inter-target distance calculation device 121 calculates a distance (overlapping prior distance) between positions observed just before the plurality of the targets overlap. An inter-target distance gate setting device 131 sets a separation determining range based on an overlapping prior distance. A separation determining device 132 judges that the overlapping targets are separated to be observed as the plurality of the targets again when a new target is observed in a separation determining range. A separation abusive remark moving distance calculating device 133 calculates a separation target moving distance. A separation target determining device 135 identifies the plurality of the targets observed by separating the overlapping targets based on the separation target moving distance. A tracking device 150 tracks the targets identified with the separation target determining device 135.;COPYRIGHT: (C)2009,JPO&INPIT
