双目立体视觉摄像机标定方法研究

amera calibration is a key technology of the application of the stereo visual system. On the basis of analyzing OpenCV camera model and the existing calibration method of binocular vision system, binocular camera calibration algorithm was designed to obtain the internal and external camera parameters. Considering the importance of the corner extraction in the camera calibration, a new corner extraction algorithm of gradient threshold was proposed, which can extract the corners effectively. The experiments show that this method is easy to be carried out and the calibration results are stable and accurate, which can satisfy the requirements of binocular stereo visual system application.
