ABSTRACT:
The invention provides a method and apparatus for recognizing physical objects, such as targets, through three dimensional image sensing. A three dimensional sensor, such as a solid-state LADAR sensor, is utilized to establish a three dimensional image of an object or target. The target will be identified or recognized in reference to a two dimensional digital representation of the object taken from a first eye point. A sensor field of view anticipated to include the object will be transformed such that sensed data is viewed from the perspective of the eye point from which the reference image was established. Selected surfaces or contours of the two dimensional image and the transformed image are then compared to identify the object or target in question.
