Multi-Sensor Multi-Target Tracking - Strategies for Events that become Invisible.
D Hutber, Z Zhang · 1995
Within the context of multi-sensor, multi-target tracking, this paper addresses the problems of dealing with objects in the world that, for various reasons, were being observed but are no longer. A modification to the usual Mahalanobis distance metric used for matching observations to Extended Kalman Filters is proposed, and also two strategies for terminating tracks and tracking objects through blind zones are described. Experimental results obtained from a sensor-equipped vehicle navigating in road traffic are presented. 1
