Most traditional approaches for stereo sensors calibration often require accurate calibration objects and complex procedures, which limit their capability in out-door work. The paper of binocular vision camera calibration method works on OpenCV and essential matrix. The method uses the program of OpenCV to calibrate the parameters of camera's internal on line. Equation of the essential matrix is formed by finding matched points in the image-pair, combined with the epipolar constraint and solved linearly. The internal parameters of the camera are rapidly got. The experimental results show that the calibration algorithm is simple and fast, and can apply to calibrate the occasion of out-door.
