Paper Abstract

This paper reports a model-based system for recognition of 3D overlapping convex objects with planar and curved surfaces. We use photometric stereo to generate a needle map, segment the needle map into planar and curved surface patches and represent a scene by means of an attributed surface patch graph. A corresponding attributed surface patch graph is used as a model for each prototype object to be recognized. The models are automatically generated from data structures of a commercial CAD-system. Our approach to recognition consists of generation of feasible interpretations and EGI matching. Local geometric constraints are used to prune the search space of feasible interpretations. The recognition system has been completely implemented. Experiments are shown for scenes of touching and overlapping objects with planar and curved surfaces.
