摘要
为了从未知摄影参数的透视图象获得三维几何尺寸,本文导出了实体的特征尺寸与透视图象的几个解析关系式以及曲线、曲面的重建方法。对于只能找出两个正交方向灭点的透视图象,本文提出了用优化方法来求出第三个灭点和其他透视参数。文中给出两个实例。
In order to obtain an accurate 8-D object configuration from 2-D image which has unknown perspective parameters. A set of analytic relations for inverse perspective transformation is derived. A optimum method is presented for solving the problem that only two vanish points can be found about the image at arbitrary position. In this paper, two examples are given by using the present method.
