| 摘 要： | 针对离散点云拓扑关系恢复及特征提取困难的问题，提出了一种健壮有效的分段光滑曲面重构方法。获得由基函数集定义的局部曲面面片图，建立尖锐特征节点的拓扑连接，通过求解一个稀疏优化问题，获得每个节点基函数的最优系数，并输出清洁的流形网格曲面。实例证明，该算法实用性好，对分段光滑曲面重构效果理想。

| Abstract: | In order to solve problems that exist in recovering datasets topology and retrieving features from point clouds,a new surface reconstruction method for piecewise smooth surfaces from point clouds is proposed.First,assemble a graph of local surface patches consisting of a set of basis functions,then establish topological connectivity among the nodes that respect sharp features,the last,search optimal coefficients for the basis functions in each node by solving a sparse optimization problem.The final represen... |
