EVIDENTIAL REASONING TO ENHANCE FEATURE-AIDED TRACKING

摘要

A process and system for enhancing tracking of one or more physical objects of interest within a search area updates track scores according to evidential reasoning. Predetermined information related to the underlying problem is stored in memory. An intermediate processor in communication between a tracking application and a reasoning engine determines for each tracked object of interest, a respective belief function, assigns an initial degree of belief, such that a component of the initial degree of belief is indicative of ignorance. Each respective belief function is forwarded to the reasoning engine. Further predetermined information related to the underlying problem indicative of a fusion network is also stored in memory and accessible to the reasoning engine. A belief supporting a respective identity for each of at least one tracked objects of interest is determined by the reasoning engine and returned to the tracking application through the intermediate processor.
