The LM algorithm has a total of three applications in camera calibration.(1) Single-target or double-target, in the case of internal-fixation, the best external parameters are calculated. The corresponding function in OpenCV is FINDEXTRINSICCAMERAPARAMS2.(2) The best internal and external parameters are calculated when the internal and external parameters are not fixed in a single target setting. The corresponding function in OpenCV is CALIBRATECAMERA
