摘 要: 对于平面散点数据,提出了逐层提取轮廓线,并将轮廓线之间的区域进行三角划分的改进算法。实现这一算法的关键是在给定阈值的条件下逐层提取内部离散点的轮廓线,再在所提取的轮廓线间进行等比例三角划分。最后,利用Lawson提出的局部优化过程来优化分割好的三角形网。 Based on the scattered points,a improved method for the triangulation between two contour lines is proposed. The problem of the new algorithm is picked-up the interior contour line ,then ploted out the triangle between the contour line.Finally,doing local optimization procedure of Lawson s on the model.
