Feasibility of Applying Stereoscopic Vision in Camouflage Design
The depth information derived from binocular disparity is a critical clue enabling observers to accurately identify camouflaged targets.Stereoscopic vision induced by binocular disparity is effective only within a specific range of distances and is primarily applied to enhance the probability and accuracy of rec-ognizing camouflaged targets.This study employs random dot stereograms(RDS)to induce stereoscopic vision in observers and collects their electroencephalogram(EEG)signals.The analysis covers the behav-ioral data of the observers,EEG fatigue indicators,and changes in dynamic functional networks through-out this process.Behavioral data demonstrates that RDS containing small disparity can induce stereoscopic vision in subjects.Significant differences in fatigue indicators can be detected at four electrodes,though the trends vary.Behavioral data also indicate that the observers have not subjectively experienced fatigue.Dynamic functional network analysis reveals that binocular disparity stimuli can induce stronger subnet-works in the α and β frequency bands of the brain functional network.This study confirms that RDS contai-ning small disparity can effectively induce stereoscopic vision in observers,leading them to pay more atten-tion to erroneous target contours without causing noticeable fatigue.The findings provide a physiological basis for employing binocular disparity in camouflage design,enhancing the stereoscopic effect of flat fake targets and camouflaged patterns.
