英文摘要: Recently, 3D image and 3D video display is a hot-spot in computer vision research area. According to the tendency of current research, volumetric display must be the kernel technique of next generation 3D display. We have confidence that similar research in global cannot reach the display effect as proposed in this research project. In this project, we plan to focus our volumetric display research work on proposing new theory, delivering new process algorithm and innovating in system design. The most important part of this research project is to solve three scientific problems which are the kernel to realize all the functions of our proposed volumetric display system. In this project, the research and design tasks include: 1) Tremendously increases the match points pair of volumetric object between its 2D projection images captured from different cameras; 2) Calculate volumetric moving vector with small displacement but large rotation angle; 3) Reconstruct 3D object with smooth surface and texture using polygon mesh grid based on match points and display live volumetric object using high frame refresh rate DLP projector and our distinguish designed optic system; According to the above research contents which are also the advantages of our method to display volumetric object, the 2014 World Youth Olympic Game has
