Design and implementation of camera calibration system based on OpenCV

For the applications of technology of camera calibration to binocular stereo vision system, the camera model in OpenCV (open source computer vision library) is discussed, the non-linear distortion of the tangential and radial distortion aberration is considered. Article gives an arithmetic of camera calibration based on OpenCV. This arithmetic makes use of the functions of the library effectively, improves precision and efficiency of computation, and has a good property for the application to multi-platform. It can meet the needs of binocular stereo vision system and other computer vision systems.
