摘　　要：随着计算机光照系统技术的不断成熟及CCD摄像机的普及,获取零件的照片影像变得越来越便捷,从而为基于照片影像的反求技术提供了一个强大的后盾.根据Torrance-Sparrow(T-S)物体表面反射模型,提出一种基于单幅照片求解表面参数的方法,并提出了对所求各表面参数进行迭代优化的算法,最后通过试验验证了算法的可行性,从而为基于单幅照片影像的物体材质反求提供一种更有效且具有一定鲁棒性的算法.With the mature of the lighting systems of computer technology and the popularity of the CCD camera, obtaining a picture of parts is getting more and more conveniently, which provides a powerful backing for the reverse technology based on image. According to the surface reflectance model of Torrance-Sparrow（T-S）, a related method of solving the surface parameters of parts based on single image is provided and an iterative optimization algorithm for those surface parameters is proposed. Finally, the feasibility of this algorithm is proved through an experiment. In that case, a more effective algorithm with certain robustness for material reverse based on single image is provided.
