is there any scipt or way to very precisely calibrate a ZED2i camera on a robot flange? I tried with 30 Positions on the robot arm but the distance to the camera is always false no matter which solver I take. I was using the OpenCV calibration with python functions. How can I test a better way?
I am in Isaac Ros and there I have the April Tag detection running. I did not use that for calibration I only use there the checker board detection on the robot with cv2 because I have there a board with exact fields. But 5cm differences are not acceptable with any solver there no matter how much points I take
