The objective of this research is to develop the theory and algorithms          for implementation of a constructive solid geometry (CSG) based 3-D             object recognition system.  The proposed system starts with segmenting          an object in a range image into primitive surface patches.  Then, the           primitive surface patches are classified as surfaces of primitive               volumes such as spheres, cylinders, cubes, or cones.  In addition, the          scales, locations, and orientations of these primitives are estimated.          The next step is to determine the order and types of set operations on          these primitives.  This will be done using a precedence graph                   describing the order of operations.  Recognition is achieved by                 matching the derived precedence graph with those in the database.               Results of this research should provide a means to unify CAD and                vision databases and help to advance the technology of automated                manufacturing systems.
