【摘要】 在影像反求设计中 ,透视图反求作图方法是由新产品的照片求解其立体外形的主要设计方法。该文研究了透视图反求作图中各个步骤的计算机仿真算法 ,如对透视条件的反求 ;透视图的平、立面投影图的反求以及透视图上点的反求。给出了应用该算法开发的CAD系统反求产品外形的实例更多还原

【Abstract】 The converse perspective drawing is a prime design method of using new product ’s photo-view to get the outline in the reversal imitating design of photo-view . The computer emulation algorithms of each step for converse perspective drawing are researched such as perspective conditions ; plan and elevation and point on perspective . An example imitating outline of product in the CAD system developing by the algorithms is presented.更多还原
