Abstract

This paper proposes a 3D model retrieval algorithm based on 2D projection point set

and gives an angle integrated 2D projection contour feature extraction algorithm by use of the boundary points of 2D projection point set

which depicts the peripheral contour of the 3D model in simple and effective way.At the same time

a profile feature extraction algorithm is given by use of the inside points of 2D projection point set

which reflects the spatial information of 3D model.The experimental results show that the algorithm can ensure the retrieval efficiency and significantly improve the accuracy of 3D model retrieval at the same time.
