摘要

Three dimensional object recognition techniques have been studied extensively by the computer vision community. Many methods have been developed for 3D object recognition. Some of them are based on aspect graphs, extended Gaussian images, superquadrics, spin images, and geometric hashing. In this paper we give a new algorithm to segment a surface into plan facet's using the normal vector information on surface. In a second step new affine invariants descriptors for surface (and Objet 3D) are presented using differential geometry. The proposed recognition algorithm will be used in an indexing system for 3D meshs retrevial via interactive web windows.
