Threaded Track Method, System, and Computer Program Product
First Claim
1. A method for determining a trajectory of an item, comprising:
- segmenting, by sensor, into track segments for the item, surveillance point data of plural sensors for tracking the item, wherein each track segment includes time serial surveillance point data for the item that is associated with a single sensor of the plural sensors;
associating the track segments for the item in a segment group; and
fusing the track segments in the segment group into a synthetic trajectory for the item.

Abstract
A system, method, and computer program product for determining a trajectory of an item includes segmenting surveillance point data of sensors, by sensor, into track segments for the item, associating the track segments for the item in a segment group for the item, and fusing the track segments in the segment group for the item into a synthetic threaded track for the item. The fusing may include filtering of the track segments for the item across track segments. The filtering across track segments may be based on a weighting of the point track data of the track segments for the item. A system for determining a trajectory of an item may include a processing device configured to execute a threaded track process to convert a data set of surveillance point data into a synthetic threaded track for the item.
