虚拟场景的立体显示技术分析-analysis on stereoscopic display technology of virtual scene

AbstractStereoscopic display of virtual scene obtains stereo pairs by two or more virtual viewpoint and completes stereoscopic display. Stereo pairs involve complex space transform, graphics rendering and view parameters, improper handling of the link will lead to the failure of acquisition. Stereoscopic display conditions are also important, such as the size of the monitor and the viewing distance. So the acquisition of stereo pairs and the last display are a whole and comprehensive consideration of these factors is necessary in order to achieve the desired three-dimensional effect. In this paper, the techniques and theories related to stereo pairs are firstly studied, and the disparity calculation formula, disparity map, depth map of stereo pairs in virtual scene is given, factors affecting the disparity: the viewpoints distance and the vergence of sight are to summarized and analyzed. Then the stereoscopic display comfort zone and he disparity limits of stereo pairs are determined based on the depth analysis of the vergence-adjustment inconsistent and the retinal image fusion. Finally, a time-sharing binocular stereoscopic display system is designed in order to verify the correctness of the conclusion of this paper, and the experiments confirms the theory proposed in this paper can be used as a basic standard in the stereoscopic display of the virtual scene to get a better three-dimensional effect.Key words: virtual scene, stereoscopic display, stereo pairs, disparity, ray tracing, comfort zone目录第一章绪论 ............................................................................................................................................................. 11.1 立体显示技术概述与应用 ........................................................................................................................ 11.1.1 立体显示技术概述 ......................................................................................................................... 11.1.2 立体显示技术的应用 ................
