Recognition And Location Of Objects From Range Images

A method is proposed for recognizing and locating previously modelled objects from range images. The objective was to develop a simple, robust, working recognition method for scenes of low or moderate complexity. Such a method is needed in many applications, e.g. fully automatic shape inspection or robotic manipulation tasks. In the method proposed here the objects are described by simple 3D vector patterns formed using certain special points on 3D edge segments. Matching is based on a hypothesis and verification approach. The performance of the method is evaluated.
