Abstract


In modern society , the graphic image acquisition and processing has been deep into every corner , has played an increasingly important role in the stability and progress of the society ! 3D stereovision This paper studies the active projection surface restoration technology and its related graphics, image processing key technology. First discuss the shortcomings Marr visual theory and analysis of its causes , on this basis , around the stereo vision - based three-dimensional surface recovery technology , a dense mesh grating projection - based 3D stereo vision surface recovery methods . For specific grid -like three-dimensional images , and taking into account the system processing speed and other factors , the proposed fast recursive median filtering , selective target enhanced image pre-processing methods such as filtering , paved the way for subsequent processing , experimental results confirmed effectiveness. Key problem for stereo vision , stereo matching technology research, on the basis of the analysis of the traditional matching method , reasonable alternatives proposed a simple algorithm from coarse to fine stereo matching method , analysis of error influencing factors , and the solution is given according to some error reasons . In order to meet the needs of modern software and production \data points and the elimination of the \OpenGL rendering bitmap image format output and dynamic display technology for real-time display of three-dimensional surface data .
