Abstract_Chinese:研究立体图像观看舒适度的影响因素已成为立体显示领域的关键技术之一．本文首次结合视觉注意机制定量研究了亮度因素对立体图像观看舒适度的影响．首先, 采用视差图和平面图像显著图相结合的方法获得显著立体图像; 然后采用改进的逐级逼近法进行主观实验, 得到显著立体图像的舒适亮度匹配图和差异图．本文所得亮度范围能够更好地反映立体图像的舒适度, 为立体图像舒适度评价及立体显示技术的改进提供了新的依据．此外, 论文采用眼动仪验证了所得立体图像显著区域的正确性．
Abstract_English:The study of factors influencing the visual comfort during watching stereo images has become a key technology of 3D display. In this paper，the visual attention mechanism is used for the first time to study how the brightness factor influences the visual comfort of stereoscopic images. Firstly，the salient stereoscopic image was obtained by combining a disparity map and a 2D salient map. Then the comfortable brightness matching map and difference map of salient stereo images were obtained through subjective experiments using an improved step-by-step approximation method. The brightness range proposed in this paper better reflects the comfort degree of a 3D image，providing a new basis for judging the comfort of 3D images and improving 3D display techniques. Besides，the eye tracker is used to verify the rationality of the salient region of stereoscopic images in this paper.
