摘要
首先利用简单几何光学与概率统计的原理,根据粗糙面激光散射特性,对双向反射分布函数进行了简化和数学统计建模.然后通过遗传算法对实验测量数据的拟合,获得更多的物体粗糙表面的光散射信息.最后提出了几种简化的数学统计模型,对实验数据进行优化拟合,均取得了良好的效果.
Abstract
The bidirectional reflectance distribution function (BRDF) is simplefied and modelled according to the principles of simple geometry optics and statistical modeling. The model is fitted with experimental datum by the optimization of genetic algorithms in order to gain more light scattering information of the object rough surface. Other models are put forward to fitting the experimental datum and the results are good.
