Study On Visual Comfort Enhancement Of Stereoscopic Video Based On Perceiving Distance Of The Viewer

In recent years，in pace with the people’s cognition of the objective worlddeepening，people‘s demands to the authenticity and intuitive of Image transmission areimproving。People are not satisfied with recognizing、reasoning and judging from the2D images, but more they hope to reduce a more realistic3D information of space in astereo display, therefore, the stereo display technology emerged as the times require.Duing to the strong sense of three-dimensional and strong sense of immersion and manyother technical advantages，the stereo display technology is now widely used inarchitectural design, precision measurement, virtual reality and many other fields.There are two sides to any utilization of science and technology. While the userenjoy the shocked stereo visual impact, they are prone to have motion sickness, nausea,dizziness and other uncomfortable symptoms because of the frequent eye movementand adjustment， this affected the popularity and development of stereo displaytechnology in a great degree. In order to solve this problem, People in recent years hasincreased the study of based on the prediction and improvement measures to the visualfatigue of the binocular parallax stereo display technology, and expecting a widelyapplicable and more comfortable display system.Therefore, this paper focuses on the study of the origin of Stereo visual fatigue,Especially the convergence and adjust the inconsistency caused by the stereo visionfatigue. Through in-depth study of the correlation between the observer positioninformation and the fusion of parallax. This paper presents a Method to enhance thecomfort of stereoscopic video by using the method of visual perception.The main content of this paper is as follows:(1) To realize the automatic measurement of line of sight, Design a kind of viewdistance measurement system by using single camera. First this paper constructs therelationship model between view visual features (eyes, nose) and Stereo video display.Then, Realize the measurement of distance by using the data fitting between the Visualfeatures and the visual spatial (angle, distance).In this paper, the design of the systemcan achieve the ranging function for the Single camera acquisition module of theunknown parameters. This system has a good portability, accuracy and high stability.(2) Put forward a method of stereoscopic video comfort enhancement based onvisual perception. In order to improve the playback effect and visual comfort ofstereoscopic videos, this paper makes full use of the disparity and the observer’s horizon adaptability in basic of solving convergence and adjustment problems, at thesame time,makes use of the viewer’s line of sight to calculate the current line of sight’sthreshold of dynamic disparity automatically.
