The Effect of Lighting on Stereo Vision Test with Random-Dot Stereogram

Depth perception is the ability of people to evaluate the relative and absolute distance. Industry practitioners such as pilots, car drivers, athletes, tailors, and seafarers, always require better stereo vision and good depth perception ability to achieve high efficiency and good performance. Meanwhile, the lighting environment is another important factor that influence their working performance. This paper investigated the influence of ambient luminance and screen brightness on depth perception based on Random-Dot Stereograms. In the experiment, we set three ambient illumination and three screen brightness to test. We found depth perception of the participants was influenced by screen brightness (16 Lux, 8 Lux and 1.5 Lux), but not influenced by ambient illumination (124 Lux, 20 Lux, 2 Lux). Hence, we could conclude that the ambient illumination of 124 Lux, 20 Lux, 2 Lux is a safe lighting that does not influence depth perception and it is not suitable for operators to work with the screen brightness of 16 Lux,8 Lux and 1.5 Lux.
