摘要: 在获得三维模型体素表示的基础上，通过比较模型体素及其26连通域体素到模型轮廓的最小欧式距离，提出了一种利用骨架体素26连通域的对称性进行三维模型骨架体素提取的算法整个算法只需遍历一次体数据集即可自动完成模型骨架的提取过程．实验表明，该算法具有较高的效率和精度．Abstract: On the basis of voxel representation of a 3D model and comparison of the minimal Euclidean distance between a feature voxel and its 26-connectness,a skeletonization algorithm is proposed by using the symmetry of the 26-adjacent of the current feature voxel.The skeleton can be extracted automatically by searching the volume dataset only once.Experiments show that this skeletonization method is efficient and accurate.
