METHOD FOR ANALYZING 3D MODEL SHAPE BASED ON PERCEPTUAL INFORMATION

摘要

A method for analyzing 3D model shape based on perceptual information is provided. The method comprises the following steps: decomposing the shape of a 3D model; extracting a skeleton based on the decomposed 3D model. This method is suitable for the shape decompositions of objects with different shapes, such as regular 3D models, 3D models with the noises, multi-rings structure 3D models and 3D models without ring structure, etc.. The method is not sensitive to the noise of the model, the segmentation speed is fast and the accuracy is high. The shape decomposition results of the method can be applied to different branch fields of computer graphics and computer vision, such as computer animation, modeling, shape analysis, classification, and object recognition. The extracted skeleton using the decomposition result and subsequent shape semantic description graph can be applied to 3D model retrieval, model semantic analysis and so on.
