local triangulation meaning in Chinese
局部三角测量
Examples
- Based on data cloud , which is measured from 3 - coordinate measuring machine ( cmm ) or so , an algorithm to search lopological structure from 3d unorganized points using envelopment - box technology is proposed in this thesis . based on this method , we searching neighbor points of sampling point . we also improve the max - min angle criteria to realize local triangulation , and then get the normal of sampling point from the triangulation
本文以测量得到的曲面数据点点云为基础，提出了一种基于包围盒的自动寻找三维散乱数据点之间拓扑结构的方法，采用该方法寻找采样点的邻域结点，并对三角剖分中的典型优化准则?最小内角最大准则提出了改进，按照改进后的优化准则实现了采样点的局部三角划分，并进一步求解得到采样点的法向量，依据法向量及邻域拓扑关系在二次曲面的基础上实现了散乱数据曲面重构中的数据点的自动分类。
