摘要
透视图的反运算是透视投影的一个基本理论问题。文中所述反运算包括2个方面:第一是根据透视图复原透视体系,即确定视点、画面和物体坐标系的相对位置;第二是根据透视图复原物体的结构和位置。
The opposite calculation is one of the essential problems in the perspec- tive projection.The opposite calculations presented in this paper include two as- pects:the first one is to resume a perspective system from its perspective drawings, i.e.to determine the relative position between the eye point,picture plane and ob- ject coordinate system;the second one is to resume the construction and position of a body from its perspective drawings.
