摘要
针对机场光伏阵列引起的眩光导致塔台交通管制员的视觉冲击问题,提出了一种光线追踪与图像处理结合的眩光测试评估模型.依据各光伏子模块布置角度复杂、难以准确界定眩光源及发生时间的特点,优化观测点视域仿真方法获得塔台管制员视觉图像,利用参数化平台Grasshopper计算眩光概率值及眩光指数值,对比分析光线追踪筛选后的潜在眩光点位及视觉任务区亮度值,以相关规范的阈值要求为依据,结合具体工程案例的测试结果,验证了仿真测试结果的有效性与实用性.
Abstract
A glare testing and evaluation model combining ray tracing and image processing is proposed to address the visual impact of tower traffic controllers caused by glare from airport photovoltaic arrays.According to the compli-cated arrangement angle of each photovoltaic module and the difficulty in accurately defining the glare source and the occurrence time,an optimized observation point field of view simulation method is used to obtain the visual image of the tower controller;Using the parameterized platform Grasshopper to calculate the glare probability value and glare index value;Comparing and analyzing the potential glare points and visual task area brightness values after ray tracing screening..Based on the threshold requirements of the relevant specifications,combined with the test results of specific engineering cases,the validity and practicability of the simulation test results are verified.
