Based On The Three-dimensional Perception Of Three-dimensional Panoramic Technology Research

Computers as a representative of the new technology have made the human race entered into a multidimensional era in the perception of information, and the human cognitive style is also changing constantly. Virtual reality is a new technology that hu-man involved in spatial information processing and interaction.Three-dimensional(3D) panoramic technology not only is an important branch of the virtual reality technology, but also the main direction of virtual reality research based on the Internet currently.Depth image based rendering(DIBR) is the main means to realize3D panoramic technology, however panoramic graph method as represent of it exists some shortcom-ings. Panorama rely on spatial information plane to save scene information, the lost of Scene depth characteristics extently influenced the immersion of perceived interac-tion and authenticity of scene reconstruction, and its development potential in space applications has be limited.Stereoscopic perception is multi-dimensional perception for observers in virtual environment. This paper try to draw the stereoscopic perception of technology into3D panoramic technology to solve the issue above. Firstly, a panoramic depth map has been built by rebuilding the scene depth information, it’s the source of the depth of information as the need of panorama spatial information recovery. On this basis, ste-reoscopic perception model has been built according to the characteristics of the pano-ramic technology. Finally a simulation system has been constructed to evaluate model performance.This paper is composed of the following content and:(1) The feasibility in the combination of stereo perception and three-dimensional panoramic has been analysised from the view of communication. As the basic of char-acteristics of panorama, the way of expression in stereoscopic perception and the de-velopment of the Internet survey, the paper evaluate the visible issue of3D panoramic technology in the basis of stereoscopic perception in internet. The results indicated that this internet express form based picture media can meet the requirement of panoramic technology expression in the current high-bandwidth.(2) Study the mode of action implied by the visual, auditory, and the environment based on human perception characteristics. The results indicated that stereoscopic par- allax, ITD, ILD, Global Environmental dynamic Change could be realized stereoscopic perception. it established the theoretical basis of the stereoscopic perception model of the virtual space in this paper.(3) Summarizes the current method of DIBR and propose the method used in this study. Based on computer vision and camera imaging model, using the epipolar con-straint to match the corresponding points of the reference image. The algorithm calcu-lated the depth of the image by simplified parallel camera model and projection trans-form properties.then panoramic depth map can be retrieved by stitching depth image sequence.(4) On the basis of the depth information, spatial perception model is established by combining3D panoramic performance characteristics. Stereo vision model is real-ized by pixel translation. ITD and ILD are used for simulating sound location. Envi-ronmental simulation is realized by global brightness changes, Lens flare and weather effect.(5) A simulation system is built by program tools based Flex. And this system display with polarizing style. This study ealuates the result in system efficiency, net-work load. The results show that system can simulate the virtual environment with a lower of network cost. Finally, This paper summarizes the lack of research and puts forward the prospect of the further study.
