摘要
本文对物体表面的反射特性进行了分析,并在图象分析中引入了梯度空间的概念,以将物体表面的灰度与相应点的表面取向联系起来,推导出在一定光照条件下物体表面的反射先强度函数。
In this paper, the author analysed the reflective properlies ofan object surface and introduced the concept of gradienct space in image analy-sis to integrate the surface bright of an object with its surface orientation. Thereflective radiance distribution function on the object surface was deduced underthe certain conditions of light shining.
