透视图在反求设计中的应用

Perspective and Its Application in Converse Drawing

对于国内厂家进口的一些先进产品或设备而言,除了照片之类的图片以外,很难再有其他方面的技术资料,故不能进一步对其产品进行了解和利用。因此,作者以设备的图像资料为切入点,通过对透视图的形成原理、照片的形成原理,同时对比人眼观察物体的情形,认为可以把照片当作透视图来处理,利用透视图的形成原理进行反推,并以二点透视为例提出一种新的反求设计的方法。

To domestic plants, there are rarely other kinds of technical data for some inward advanced products and equipment, except for photos. As a result, these products and equipment can＇t be further understood or made use of. Through study on principium of prospective and photograph as well as comparison of it and the way that people observe objects, it is concluded that photos can be treated as prospective. With image information of equipment, based on reverse thinking of principium of prospective, a new way for converse drawing using two-point perspective is introduced here.
