Get the relative position of the camera with extrinsic parameter but z-axis not facing to the camera

Object: I'm trying to get the relative position of the two camera's with calibration. I'm using openCV to achieve this goal. criteria = (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 30, 0.001)...

Your approach is correct. To get the extrinsic parameters, extract the checkerboard corners from the images, then call cv::solvePnP to the get the camera pose with respect to the checkerboard. You mus...
