SYSTEM AND COMPUTER IMPLEMENTED METHOD FOR TRACKING OBJECT USING SURVEILLANCE DATABASE

摘要

PROBLEM TO BE SOLVED: To provide a method and system for tracking objects using a surveillance database storing events acquired by a set of sensors and sequences of images acquired by a set of cameras. SOLUTION: Sequences of temporally and spatially adjacent events sensed by the set of sensors form a set of tracklets. Each tracklet has endpoints being either a track-start, track-join, tracklet-merge or tracklet-end node. A subset of sensors is selected, and a subset of tracklets associated with the subset of sensors is identified. A single starting tracklet is selected. All sequences of tracklets temporally and spatially adjacent to the starting tracklet are aggregated to construct a tracklet graph. The track-joint nodes and the track-split nodes are disambiguated and eliminated from the track graph to determine a track of the object in the environment. COPYRIGHT: (C)2008,JPO&INPIT
