Method and system for recapturing a trajectory of an object

The present invention is in the field of sensor fusion, and discloses in one embodiment a method for extracting the trajectories of moving objects from an assembly of low-resolution sensors, whose spatial relationships are initially unknown, except that their fields of view are known to overlap so as to form a continuous coverage region, which may be much larger than the field of view of any individual sensor. Segments of object trajectories may be extracted from the data of each sensor, and then stitched together to reconstruct the trajectories of the objects. The stitching process also allows determination of the spatial relationships between the sensors, so that from initially knowing little or nothing about the sensor arrangement or the paths of the objects, both may be reconstructed unambiguously.
