摘　　要：针对飞机驾驶舱中的眩光评估问题,提出了一种基于SPEOS/CATIA的量化评估方法.该方法综合运用SPEOS/CATIA软件进行眩光场景的仿真,眩光源通过基于SPEOS/CATIA的二次开发自动获得,同时取得眩光源亮度、背景亮度、位置指数和光源立体角等参数,进而计算得到合适的眩光量化评估结果.最后,以某型飞机驾驶舱为例,进行了夜间和白天的眩光评估.计算结果表明,该方法能自动、快速地评估驾驶舱内眩光分布和量级.In this paper a novel method based on SPEOS/CATIA to evaluate glare of flight deck was proposed. The secondary development work was carried out from SPEOS/CATIA framework, the glare sources could be detected, and the key parameters of quantifiable evaluation were calculated as well, such as source luminance, background luminance, position index and solid angle of source. And then, the desired glare index could be computed automatically and quickly. Finally, unified glare rating （UGR） and daylight glare probability （DGP） equation were utilized as example to predict the glare pollution in flight deck. The results indicate that the proposed method is convenient for safety design of flight deck.
