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.
Aiming at the problem of glare assessment in aircraft cockpit, a quantitative assessment method based on SPEOS / CATIA is proposed, which uses SPEOS / CATIA software to simulate the glare scene. The glare source is automatically obtained through secondary development based on SPEOS / CATIA , Glare source brightness, background brightness, position index and solid angle of the light source were obtained at the same time, and then the suitable evaluation results of glare quantification were calculated.Finally, with the cockpit of an airplane as an example, nighttime and daytime glare assessment was performed. The results show that this method can automatically and quickly evaluate the glare distribution and magnitude in the cockpit.
