Three-dimensional image or three-dimensional video can provide the s cene depth information of media,and it has become an academic hotspot in image d isplay area.With the development of three-dimensional 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 t he phenomenon that one same stereoscopic image is displayed on different size stereoscopic display screens a nd to propose an enhanced stereoscopic display method by adjusting the image parallax.In the first step,t his procedure applies stereo matching algorithm to obtain the horizontal parallax of stereoscopic image.In t he second step,the proposed method uses a reliable access composed of image segmentation and connectivity de tection to determine the boundaries of horizontal parallax.The third step,in order to normally display th e stereoscopic image,the boundaries and other parameters are combined to adjust the positions of the left and right views in the original stereoscopic image,which can form a comfortable visual effect.The experiment results indicat e that the adaptive adjustment method can improve the stereoscopic display sign ificantly.
