A Calibration Method Based on OpenCV

To satisfy the demand of the real-time computer vision system, a method of camera calibration was analysed. According to the camera model from OpenCV(Intel Open Source Computer Vision Library), with radial aberration and tangential aberration considered, Zhang´s arithmetic of camera calibration was applied. As the experimental result showed, the arithmetic exerted OpenCV library function at a great extent, and had a high-level accuracy and efficiency, also a good property for the application to the multi-platform, and can meet the need of most real-time computer vision system.
