Optimization and Experimental Analysis of Dynamic Range for Stereoscopic Display Based on Visual Mechanism
Recent concepts,such as the"metaverse"and"digital twins",indicate a greater necessity for higher perception quality from stereoscopic displays.This can be addressed by applying human factors engineering,which is an advancement in stereoscopic-display technology.Stereoscopic-display technology can be further developed by employing ergonomics to enhance the perception quality of stereoscopic displays.To optimize the perception quality of stereoscopic scenes,herein we propose a method to improve the dynamic range of stereoscopic scenes using the binocular fusion and binocular rivalry mechanisms in the human-eye visual system.This approach is based on the visual characteristics of human eyes when viewing stereoscopic scenes.Results of three progressive visual-perception tests confirm the feasibility of the approach.Stereo images subjected to the proposed method show improved visual-perception quality,and the statistical results show a significant increase in their dynamic ranges,all of which are within the dynamic range of good human-eye perception(0.35<μ<0.61).Additionally,the approach does not affect depth perception based on stereo images.This technique can offer a theoretical foundation for improving the quality of stereoscopic-scene perception.
