中文摘要：

针对不同尺寸立体显示器播放立体视频时立体视觉效果存在的差异，提出一种通过调节图像水平视差改善立体显示效果的方法。首先应用立体匹配算法得到立体图像初始视差，通过图像分割与连通性检测从中可靠地获取水平视差范围；为保证图像中全部景物在舒适立体融像区内成像，根据显示器尺寸与观看距离，调整左右眼图像在原立体视频中相对位置，形成合理的水平视差，从而在立体显示器上产生舒适的立体视觉效果。实验证明，本文提出的方法可自适应地调整立体图像的水平视差并较好地改善立体显示效果。

英文摘要：

Three-dimensional image or three-dimensional video can provide the scene depth information of media,and it has become an academic hotspot in image display area. With the development of three-di- mensional display technology, viewers can get more colorful and vivid visual experience. At the same time, people have paid more and more attention to improving the visual experience comfort of stereoscop- ic display. The main purpose of this paper is to analyze the reason for the different visual effects caused by the phenomenon that one same stereoscopic image is displayed on different size stereoscopic display screens and to propose an enhanced stereoscopic display method by adjusting the image parallax. In the first step,this procedure applies stereo matching algorithm to obtain the horizontal parallax of stereo- scopic image. In the second step,the proposed method uses a reliable access composed of image segmen- tation and connectivity detection to determine the boundaries of horizontal parallax. The third step, in or- der to normally display the stereoscopic image, the boundaries and other parameters are combined to ad- just the positions of the left and right views in the original stereoscopic image, which can form a comfort- able visual effect. The experiment results indicate that the adaptive adjustment method can improve the stereoscopic display significantly.
