【摘要】：3D技術(shù)的發(fā)展受到其引發(fā)的不舒適感的限制,長時間觀看立體顯示影像將會引起立體視覺疲勞,一種客觀評價立體視覺疲勞的有效指標(biāo)亟待提出.本文利用EEG(electroencephalography)三個頻帶θ(4~8 Hz)、α(8~13 Hz)、β(13~22Hz)的相對能量及其能量比值E_((α+θ)/β)、E_(α/β)、E_((α+θ)/(α+β))在八個不同腦區(qū)及整個腦區(qū)的54個指標(biāo)作為備選,借助配對t檢驗、灰色關(guān)聯(lián)度分析(GRA)、支持向量機(SVM),最后得出指示由立體深度運動引發(fā)的視覺疲勞的最佳腦電指標(biāo)為:頂區(qū)E_(α/β).并比較了三個頻帶相對能量在不同疲勞狀態(tài)的變化:疲勞狀態(tài)下,α頻帶明顯上升(p0.01),β頻帶明顯下降(p0.01),θ頻帶保持穩(wěn)定.
[Abstract]:The development of 3D technology is limited by the uncomfortableness caused by 3D technology. Viewing stereoscopic images for a long time will cause stereo vision fatigue. An effective index to evaluate stereoscopic visual fatigue needs to be put forward. In this paper, the relative energy and energy ratio of three frequency bands 胃 ~ (4) ~ (8) ~ (8) H ~ (z), 偽 ~ (8) ~ (13) H ~ (2 +), 尾 ~ (13) ~ (13) ~ (22) H ~ (2) of EEGG electroencephalography (EEGG) are used as the relative energy and the energy ratio of E (偽 胃 / 尾) in eight different brain regions and the whole brain region as an alternative. Grey correlation degree analysis (GRA), support vector machine (SVM), and SVM.Finally, the best EEG index to indicate visual fatigue caused by stereoscopic depth motion is as follows: top region E (偽 / 尾). The changes of relative energy of three bands in different fatigue states are compared. Under fatigue condition, the 偽 band increases obviously, the 尾 band decreases obviously, and the 胃 band remains stable.
