| 摘 要： | 针对分段处理后的空间散乱点集,引入启发函数选择投影方向,通过投影映射把空间离散点三角剖分问题转化到二维空间处理。建立点集投影凸域网格来形成节点邻域,以提高剖分过程中对节点搜索效率,同时采用三角形边扩展法建立投影点集三角网,进而实现对空间散乱点集的三角剖分。

| Abstract: | To segmented3D data points,this paper presents a optical function to choice projection plane.With projecting transformation it can alter triangulation of3D data points to2D region.The paper also describes the forming procedure of the node searching domain from the grid of projected data point-set,in the meantime ,it gives triangulation procedure of side-based expanding. |
