A method for extracting 3-D shape primitives of a polyhedral object from the boundary face and edge data is presented. These primitives which provide semantic information as well as geometric information are useful in CAD/CAM applications and in model-based vision. A graph-based hypothesis generate-eliminate approach is used to identify and classify 3-D shape primitives of the object. Several techniques, such as node unification and virtual links, are introduced to solve the problems associated with the interaction between the primitive features. Results from a system implemented in Lisp are presented.
