Binocular stereovision camera calibration

In view of the binocular stereo vision calibration problem, this paper offers a method of camera calibration which is between the traditional calibration and the self-calibration. To compare with traditional methods, set the internal parameters distortion parameters and external parameters calibrated respectively. First of all, working out the internal parameters by Zhang Z.Y plane calibration method; secondly, calculating the distortion parameters based on the radial distortion lens; finally, discussing the calibration methods of external parameters in the case of the camera is moving, to avoid the problem of recalibration when the camera is moving in original calibration environment. The experiment according to the template principle of traditional calibration, combined with binocular stereovision model, verifies the feasibility of this separation calibration method.
