摘　　要：为了更准确地构建非刚体三维网格模型之间的形状对应关系,提出一种改进的热核特征分析与研究三维网格模型之间的局部对应关系。该方法利用压缩流形模式压缩三维网格模型的特征函数,截取局部顶点;利用乘法器交替方向(ADMM)优化计算三维网格的压缩流形基替换传统的离散化拉普拉斯-贝尔特拉米算子以改进热核特征;选取相同的压缩部位进行局部的对应匹配。实验结果表明,基于改进的热核特征与传统的离散化热核特征相比有更加突出的效果。An improved thermonuclear feature is proposed to analyze and study the local correspondence between 3D mesh models in order to construct the shape correspondence between non-rigid 3D mesh models more accurately.This method used compression mode to the manifold compression characteristic function of 3D mesh model and intercept local vertex.Multiplier alternating direction(ADMM)was used to optimize computing three-dimensional grid on the compression of manifold to replace the traditional discrete Laplace-Beltrami operator to improve the fusion characteristics.The same compression parts were selected for local matching.The experimental results show that the improved thermonuclear feature is more effective than the traditional discrete thermonuclear feature.
