摘要: 研究了从给定的断层轮廓重构三角曲面的问题,提出使用距离场的思想来解决连接轮廓线法重构物体表面形状中的分叉问题以及轮廓对应问题。给出了连接两个连续断层上的特征点的方法,并通过在相邻断层间创建中轴,连接中轴和两个连续断层轮廓上的对应点,构成三角形,并采用递归的方式,使得最终重构出的曲面具有连续性,同时解决了当相邻断层轮廓差异较大时的分叉问题。

Abstract: The problem of reconstruction to triangular surfaces from given contours is considered. A new approach that the main idea is to employ discrete distance fields enhanced with correspondence information is presented. It solves the branching problem and correspondence problem. The methods of connecting feather nodes from two consecutive slices are presented. Through recursive producing medial axis, the surfaces of reconstruction become smooth. This can solve the branching problem by creating intermediate contours where adjacent contours differ too much.

Key words: Distance field, Reconstruction from contours, Triangulatin
