摘　　要：为了更好地评价立体视频的舒适程度,提出了将立体视频中存在的3种视差与物体的运动特性作为影响立体视频舒适度重要因素,并利用这4种因素在不同的立体视频内容中得到的数据变化建立符合人眼感知的客观舒适度评价标准。首先提取帧内显著物体视差、帧内相关背景视差、帧间视差和运动变量4种因素;然后结合深度感知理论和最小二乘拟和方法建立评价模型;最后利用主观评价的方法对模型进行评定。结果表明,本文方法可以很好地模拟人眼的主观感受。In order to evaluate the comfort degree of stereo video better, in this paper, the motion charac- teristics and three kinds of parallax of the object are put forward as the important factors affecting the stereo video comfort degree. Using these four factors obtained in different stereoscopic video content changes,an objective evaluation of comfort standards in line is established with the human eye views. Firstly, extract four influential factors of the stereo video comfort,including intra-frame＇s parallax of sig- nificant objects,intra-framers parallax of related background, movement variables and the parallax be- tween frames, then combine the theory of depth perception and least-square fitting method to establish an evaluation model, and finally use the subjective evaluation method to assess the model. Thus we obtain a method which can evaluate the comfort of stereo videos before these stereo videos are viewed. The evalu- ation results show that the model proposed in this paper can be a good simulation of the human eye＇s subjective feelings,and it is important for the study of stereo video comfort perception.
