| 摘 要： | 基于三维重建工作中物体截面轮廓线序列中相邻轮廓线基本相似的事实，提出了物体截面轮廓线点集之间三角划分的一种快速算法．算法首先寻找轮廓线的控制点，对每两条相邻轮廓线的控制点进行配对；然后将这样两条轮廓线之间的三角划分分配在多个小曲线段对之间进行，并且根据事先匹配的控制点，在每个小的区域中进行简便快速的三角划分．实验验证了算法的有效性．

| Abstract: | Based on the fact in 3D restoration that the sequential section contours of an object are more or less similar to adjacent ones, a quick method for the triangulation between two section contours is proposed. The dominating points of every contour are located, then the dominating points of two contours are matched to each other, so the whole area between two contours is segmented into many smaller ones. Because of the pre matched dominating points, a simple and quick triangulation can be carried out in each small area. Testing results are given to show the effectiveness of the method. |
