Abstract: Presented a method by itergrating multi-feature base on two-dimensional orthogonal projection to improve retrieval accuracy. Firstly, we obtained two-dimensional orthogonal projections of the 3D models, and then two features which among two-dimensional orthogonal projections were used and each feature has a weight These features were syncretized on output layer. I3y plusing the two results of the features with their weights, the whole result could be got. According to users' feedback, the system changed the weights of each feature dynamically. Experiments show retriving accuracy and efficiency have a greater improvement than that on single feature.
