摘要

提出并实现了一种大气偏振光分布模式优化仿真算法.为了提高大气偏振成像等应用的运行效率,利用四叉树对半球空域的偏振光分布模式进行三维划分、组织,提出了近似优化偏振光分布位置、强度的方法,给出了具体的半球空域偏振光分布建模过程、分析.最后,结合PG偏振成像算法给出了三组不同参数的大气偏振光分布优化仿真,并给出偏振光分布仿真结果及偏振图像的对比分析.仿真结果表明,利用大气偏振光分布模式优化仿真方法,能提供较高的基于设定参数方式的用户交互性能,能有效降低相关偏振成像应用的运行时间,提高仿真效率,并且得到的偏振图像灰度分布偏差变化较小.%A polarimetric light distribution pattern simulation method was introduced and realized.To increase the operating efficiency of atmosphere polarimetric imaging application,as the spherical atmosphere polarimetric light distribution pattern is divided and organized through quadtree,it approximately optimizes the strength and position of polarimetric light.In the paper,the specific modeling process and analysis were presented.Finally,three simulation tests and results with different parameters using PG polarimetric imaging algorithm were given.The simulation results show that the method can provide high operating interactive capability through setting parameters,efficiently optimize atmosphere polarimetric light distribution pattern,and decrease running time of relevant polarimetric imaging applications,while the gray scale distribution bias of polarimetric images is small.
