Method and Apparatus for Correlating Object Measurements with Object Measurement Estimates.
Abstract
A method for efficiently determining correlations between tracks and objects in a multi-target tracking system comprises defining a current track measurement estimate for each track, and building a measurement tree from the track measurement estimates. The estimates may be either point or volume measurement estimates. After defining the measurement tree, a measurement defining a volume measurement is taken of one of the objects. The measurement is correlated to one or more tracks by searching the measurement tree. The tree is searched by determining, at each node of the tree, if the volume measurement intersects the particular track point or volume measurement estimate associated with the particular node. Additionally, a search volume is associated with each node, such that the decision to search further paths emanating from a particular node is made by determining if the volume measurement intersects the associated search volume.
