EFFICIENT 3-D OBJECT REPRESENTATION AND RECOGNITION BASED ON CAD

In this paper, a solid modeler by which one can automatically and effi ciently build the 3-D object models is implemented. The proposed metho d provides a fast and compact object representation by incorporating v iew-dependent features and the object-centered representation. To test the efficiency of the proposed object representation scheme for recog nition, we have implemented a matching process based on the constraine d search paradigm. Experimental results show that the proposed method can reduce the time and storage space during the recognition process.
