摘要
SFS(由明暗恢复形状)方法研究是计算机三维视觉研究领域中的一个重要分支。以朗伯体光照漫反射模型为基础,对物体表面图像明暗恢复其表面高度和梯度的抽象模型进行分析,研究基于朗伯体定律求解受光点梯度的算法及SFS方法的实现原理。
SFS(shape from shading) is an important branch in 3-D computer vision.In this paper,a calculus of obtaining height and gradient from image superficial shading is analyzed carefully based on Lambert reflectance model,and makes an intensive study on algorithms of reverse calculation in the spot gradient and realization principle of SFS.
