任意空间位置回转二次曲面体的三维重建

3D RECONSTRUCTION OF QUADRIC OF REVOLUTION OBJECT PLACED ARBITRARILY FROM 2D ORTHOGRAPHIC VIEWS

本文提出了一种适用于任意空间位置摆放的回转二次曲面体的三维重建算法，主要技术途径是根据回转二次曲面体的投影特性，定义了曲面上的一些具有特征性质的点和线。通过寻找特征点，用特征匹配的方法，实现了空间任意摆放的回转二次曲面体的三维重建。

 Reconstruction 3D objects from 2D orthographic views is a significant subject both in CAD/CAM and in Artificial Intelligence fields. This paper develops a CharacterPointMatching method, which finds out the characterpoints in 2D curved lines at first, then generates the 3D curved lines through the corresponding different views by using 2D Characterpoints, and finally forms the 3D quadratic objects from 3D curved lines. Several examples are used to show the capability of this algorithm. 
