摘　　要：在涉及到理想透视的画法问题上,通常仅限于对细节的添加,缺少对透视体系的构建。根据给定的物体及其理想透视图的初始条件,讨论了根据透视关系如何确定物体空间位置和视点位置的方法。由此构建了完整的透视体系,解决了复杂形体与结构的理想透视图画法。该方法对于在实际中需依据摄得的图像和实际场景来确定摄影者的方位也提供了依据。Concerning the making of ideal perspective drawings, the discussion is always limited to minor details, but lack for constructing of perspective system. The method of how to determine the orientation of object and location of viewpoint is proposed according to the initial conditions of ideal perspective drawing for a given object. Thus a complete perspective system is constructed and the perspective drawings of complicated structures can be worked out. The method also provides the possibility to solve the problem of locating the photographer＇s position in a taken image.
