摘要：
In this paper a novel 3D orthogonal Polynomial moment based on 3D U system polynomials is proposed, and is used for 3D model retrieval. U system is a kind of complete and orthogonal polynomials system. In this paper, we combine U system with spherical harmonic functions and define a shape descriptor-U system rotation invariant moments. The performance of the proposed method is evaluated by constructing precision/recall diagrams. Results clearly demonstrate effectiveness of this new method in the 3D-model retrieval process and superiority over the traditional Zernike moment invariants..
