眨眼特征与颜色不对称立体图像视觉舒适度的相关性分析

Correlation analysis between blink characteristics and visualcomfort of color asymmetric stereo images

提出了一种从眼动生理指标角度客观评价立体内容视觉舒适度的模型.选用颜色色调不对称的立体图像进行了视觉舒适度的主观评价实验,并开展了记录眨眼数据的眼球追踪实验,通过对主客实验数据的分析,验证了在色调不对称立体图像的刺激下视觉舒适度与眨眼次数呈高度负相关关系,而与平均眨眼持续时间没有明显的相关关系;得到了基于眨眼次数的立体图像视觉舒适度客观评价模型.分析模型可知:观看颜色色调不对称立体图像10 s内平均眨眼次数超过9.99次时,开始感觉到视觉不舒适.研究结果可为立体显示的视觉适度评价提供借鉴.

This study proposes a method to objectively evaluate the visual comfort of stereo content from the perspective of eye-movement physiological indicators. The subjective evaluation experiment of visual comfort was conducted using hue asymmetric stereoscopic images, and the eye-tracking experiment for recording blink data was carried out. The analysis of the subjective and objective experimental data verified that the visual comfort was highly negatively correlated with the number of blinks for the hue asymmetric stereo images, but not with the average blink duration, and the objective evaluation model of visual comfort based on the number of blinks was obtained. The model shows that the brain starts to feel visual discomfort when the average number of blinks exceeds 9.99 within 10 s for viewing a hue asymmetric stereoscopic image. The results of the study can be used for a reference in visual comfort evaluation of stereoscopic displays.
