3D visual comfort can be influenced by such common factors as binocular parallax, 3D image contrast, viewing distance, and illumination condition. This paper investigates the effect of contrast enhancement and illumination condition on 3D visual fatigue by performing a visual fatigue measurement experiment, of which subjects need to watch 3D images under two illumination conditions and finish a comfort judgment task. The proportion of discomfort images, the subjective evaluation of visual fatigue under 100 lux and 500 lux illumination conditions, the effect of image contrast enhancement on 3D visual fatigue, and the relationship between visual fatigue and proportion of discomfort images were analyzed, respectively. The experimental results showed that both the contrast enhanced by Laplacian algorithm and low illumination condition have positive influence on 3D visual perception of eyes; the 3D visual fatigue of contrast enhanced by Laplacian algorithm under low illumination condition was less than other situations in the experiment. Moreover, it was examined that the proportion of discomfort images can be potential prediction indicator of the 3D visual fatigue.

对比度增强和照明条件对3D视觉疲劳的影响研究

3D视觉舒适度可能受到诸如双眼视差，3D图像对比度，观看距离和照明条件等常见因素的影响。本文通过进行视觉疲劳测量实验来研究对比度增强和照明条件对3D视觉疲劳的影响，其中受试者需要在两种照明条件下观看3D图像并完成舒适性判断任务。分别分析了不适图像的比例，在100 lux和500 lux照明条件下的视觉疲劳的主观评估，图像对比度增强对3D视觉疲劳的影响以及视觉疲劳与不适图像比例之间的关系。实验结果表明，拉普拉斯算法增强的对比度和低光照条件对眼睛的3D视觉感知都有积极的影响。拉普拉斯算法在低照度条件下增强的对比度的3D视觉疲劳小于其他情况。此外，检查了不适图像的比例可以作为3D视觉疲劳的潜在预测指标。
