Almost everything one needs to know about image matching systems

Expert InsightsPublished 1980

Describes the design and evaluation of map-matching systems. The missile map-matching problem for guidance updating or target homing is to locate the position of a sensor image relative to a reference map stored onboard. A number of error sources effect the system performance measured in terms of probability of false fix. This paper describes these error sources (included are the time and spatial varying nature of the scene signature and the problems inherent in reference map construction), categorizes them, and analyzes the ability of various matching algorithms to accommodate these errors. This paper also describes the utility of a new class of algorithm--the hybrid. Also discussed are mathematical models of the process and methods for estimating system performance in near real time.
