Abstract
Target tracking by area correlation involves matching a stored reference image of the target to live search scenery. The performance of the area correlator can be severely degraded by target magnification and three-axis rotation. This report presents 2 algorithms that estimate magnification and rotation angles, and allow the tracker to take compensating action via zoom lens and roll gimbal. The first algorithm, application to fixed targets, estimates rotation about the line of sight only (roll angle). The second algorithm estimates rotation in 3 axes, as required for maneuvering targets. The presentation of both algorithms is supported by simulation using photographs and artificial images.
