摘要
本文主要研究考虑分辨率情况下物体投影图的获得,采用了一种新的方法一观测球法,以大家比较熟悉的透视投影图为例,对其做了定量分析和比较。推导过程简单,公式紧凑,便子计算机实现.程序流程简单易读,计算实例论证了本方法的有效性.该方法同样适用于其它投影变换,是一种通用的方法.
This paper mainly studies the acquisition of object projection when we take account of computer resolution. A new method, observation sphere method, is introduced In order to analysis and compare with it readily, the mathematical model of this method is built. ms derivation is very simple and compact. In this paper two examples are provided to test its validity. This mathematical model can be used in other projection transform . So it is a very important and unversal measure in computer vision.
