Abstract:This paper proposed a two-dimensional orthogonal projection similarity-based 3D model retrieval system.Firstly,obtained two-dimensional orthogonal projections of the 3D models,and then got similarity among 3D models through matching the shape similarity among two-dimensional orthogonal projections.The experiment results show that this method is effective,and this approach is robust against translation, scaling and rotation transform.
Key words:3D model retrieval; two-dimensional orthogonal projection; contour angle; comparability ......
