水平视差是影响3D图像舒适性的重要因素之一。采用不同等级水平视差的3D图像作为刺激信号，通过记录被试者的EEG反应信号，提取出被试者观看不同等级水平视差3D图像的ERP波形；同时记录被试观看这一系列3D图像舒适性体验的行为数据，并计算其舒适性检测率。通过EEG信号分析可见，无论在交叉或者非交叉水平视差情况下，3D图像水平视差舒适范围在45’以内；水平视差在45’~75’时，交叉视差3D图像ERP 波形280 ms附近的幅值与不舒适的程度相关，非交叉视差3D图像ERP波形250 ms附近的幅值与不舒适程度相关；检测率曲线结果和主观评价结果显示：3D图像水平视差的舒适性范围在45’以内，水平视差在45’~75’时，3D图像不舒适程度随着视差的增加而增大。结果表明：EEG分析、检测率曲线和主观评价结论一致，因此，可以使用EEG分析水平视差对3D图像舒适性的影响。

Horizontal parallax is one of important factors that affect 3D images comfortableness. 3D images of different horizontal parallax were used as stimulate signals, by recording the EEG signals, the ERP waveforms of 3D images were extracted. At the same time, behavioral data of comfort experience of the 3D images was recorded and their comfort detection rate was calculated. EEG analysis result shows that no matter in the case of crossed or uncrossed horizontal parallax, comfort range of 3D images horizontal parallax is within 45’ . When horizontal parallax is from 45’ to 75’ , the ERP amplitude of around 280 ms is associated with the discomfort level of crossed parallax 3D images and the amplitude of around 250 ms is related to the discomfort level of uncrossed parallax 3D images; Detection rate curve and subjective evaluation results show that comfort range of 3D images horizontal parallax is within 45’.When horizontal parallax is from 45’ to 75’ , the discomfort degree of 3D images is increased. Results show that EEG analysis, detection rate curve and subjective evaluation conclusion is consistent, so EEG can be used to analyze the effect of 3D images comfortableness on horizontal parallax.
