3D model retrieval algorithm based on slice-cutting
一种基于切片的三维模型检索算法*

For retrieving similar models more efficiently from 3D model database, this paper proposed a slice-cutting based 3D model retrieval method. Firstly, used PCA to preprocess a 3D model. Then, cut the preprocessed 3D model into slices using planes normal to principal directions. Finally, selected the ratio among the areas of these cutting slices as the representation of a 3D model and used to calculate the similarity between models. It developed a retrieval system based on this algorithm. The experiment adopted PSB 3D model database for retrieving. The results indicate that cutting slices based 3D model retrieval method is effective and promising.
