不同照明环境下2D/3D显示视疲劳研究

为比较不同照明环境下观看2D和3D视频所产生的视疲劳的差异，采用主观问卷和客观测量两种方法进行实验研究。主观问卷结果表明，在4种实验条件下，被试产生了明显的视疲劳；客观视觉参量测量结果显示，两种照明环境下，CFF、NRA和PRA值在实验之后下降显著（p<0.01），且LED照明环境下CFF值的下降更大。照明对CFF影响的显著性水平为0.038，其他各项参数在两种电影版本和两种照明环境下均没有显著性差异。结果表明，实验之后主客观的疲劳均显著增加，但没有证据表明观看3D视频比观看2D视频更易产生视疲劳。

Investigation of visual fatigue caused by 2D/3D display under different illuminations

Subjective and objective measurements are used to compare the differences of visual fatigue caused by watching 2D and 3D movies under LED and fluorescent illuminations. The results of subjective questionnaires showed that, watching movies can lead to apparent visual fatigue. And results of objective measurements showed that CFF, NRA and PRA decreased significantly after watching movies(p<0.01) under two different lighting conditions. CFF has a more significant decline under LED lighting condition, the p value of influence of lighting condition on CFF is 0.038 . There are no significant differences between 2D and 3D movies under two kinds of lighting conditions in terms of the objective measurements. The conclusion is that the visual fatigue increased significantly after the experiment while no evidence shows that watching 3D movies can cause more visual fatigue than watching 2D movies.
