摘要
为了表征复杂涂层表面的光学散射特性,基于微面元理论的偏振双向反射分布函数模型,利用遗传算法从实验数据中反演出模型的关键参量。采用C＋＋语言对偏振双向反射分布函数模型进行了数值模拟,分析了模型参量对偏振双向反射分布函数的影响。数值模拟结果与实验数据的对比表明,该模型算法有较高的模拟精度,可以为后续的目标特征提取与识别工作提供参考。
Abstract
In order to represent optical scattering properties of the complex painted surfaces, based on microfacet theory for polarized bidirectional reflectance distribution function (BRDF), genetic algorithm is used to get the key parameters in the model. Numerical simulation is done using C++ language and the impact of the model parameters is analyzed. The comparison between numerical simulation results and experimental data indicate: this model has the higher precision for simulation, and can be used as a reference for target feature extraction and recognition in the future.
