Abstract :
Introducing general CAD descriptions in object recognition systems has become a major field of research called CAD based vision (CBV). However, the major problem using free-form object descriptions is how to define recognizable features which can be extracted from sensor data. We propose new methods for the extraction of 3D space carves from CAD models and from range data. Object identification is performed by correlating feature vectors from significant subcurves
