3D立体图像的生成及深度信息的提取

Based on the studies of 3D stereoscopic display methods, the active shutter stereoscopic display method is used in the paper. 3D stereo images is generated by stitching images and watched by NVIDIA 3D VISION Stereo Vision. A system of depth information extraction is proposed in this paper，which is based the research of binocular stereo vision theory. With the system，the camera calibration method is Zhang's flexible new method，select feature point and get the circle centre point by Hough transformation, get matching double points with feature match, recover depth information by triangle measuring method. With the comparison of the recovery depth info and the measuring depth info, the experiment shows that the recovery method is reliable. With an object-oriented design methd in VC++, related algorithm software including camera calibration, feature extract, stereo matching and depth information extraction is developed.
