碩士 === 中華大學 === 資訊工程學系(所) === 99 === The advances in 3D data acquisition, graphics hardware, and 3D data modeling and visualizing techniques have led to the proliferation of 3D models. The searching for specific 3D models becomes an important issue. Techniques for effective and efficient content-based 3D model retrieval have therefore become an essential research topic. In this thesis, exterior and interior features are proposed for 3D model retrieval. The exterior features are angle descriptor (AD) and symmetric descriptor (SD). The interior features are angle 3D-ART descriptor, radial 3D-ART descriptor and curvature 3D-ART descriptor. To improve the retrieval results, the exterior and interior features will be combined based on dynamic multi-descriptor fusion (DMDF). Experimental results show the proposed methods have a good performance.
