三角网格模型体素特征分割

针对现有机械制造领域网格模型分割结果缺少工程含义的现状,提出了一种三角网格模型体素特征分割方法。首先在对三角网格模型分割的基础上,对由网格分割得到的每个子网格进行曲面类型识别,然后在基本体素及典型结构显著特征表示的基础上,把识别出的曲面集合与基本体素及典型结构进行匹配,从而将分割结果分类为自由曲面、基本体素和复杂体素,实现具有工程含义的体素特征分割。该方法可以降低模型重构的难度,加快模型重构的速度。

Voxel Features Segmentation of Triangular Mesh Models

Because the existing segmentations of models lack engineering semantics in mechanical manufacturing,the voxel features segmentation of triangular mesh models was proposed.Based on segmentation of triangular mesh models,surface type is identified for each mesh,and then the identified surface set is matched with basic voxels or typical structures represented by salient features,so that the segmentation results are classified as free surfaces,basic voxels and complex voxels.The voxel features segmentation with engineering semantics is achieved,which can make reconstruction of models easier and faster.
