摘要
本文描述了一种基于表面方向及恢复树,从景物轮廓线求三维景物表面形状的方法.文中还描述了两个消影点,一个消影点及无消影点时,计算表面方向的新算法,并给出一个简单例子.
A method of recovering surface shape from the contour is presented. It is based on a graph and a recovery tree. Also some new algorithms of computing surface orientation from two vanishing points, one vanishing point, and without vanishing point (under certain condition), are presented. To illustrate the method, a simple example is given.
