Paper Abstract

The key problems to be solved in stereo HMD (Head-Mounted Display) used in augmented reality are analyzed, such as brightness of image, fusion of virtual and real scene, binocular rivalry, occlusion, distortion, stereo vision and tracking of head and line of sight. An experimental platform of HMD is developed by discrete elements to research the key problems. The problem of fusion of virtual and real scene can be solved effectively by replacing the common beam splitter with polarization beam splitter in combiner. The variations of HMD vision effects including binocular rivalry with binocular overlapped range are investigated, and the results indicate that the optimal effect is achieved when the binocular overlapped range is 33~50% of the monocular field of view (FOV). At last, stereo vision is realized in HMD by the stereo image pairs made up according to the parallax theory.
