If I use an uncalibrated camera to obtain the pose of an AprilTag, what is the reference coordinate system for this pose
Tom posted in LeRobot •The pose is still defined in the camera coordinate system regardless of calibration. However, without calibration, the estimated pose lacks metric scale and cannot recover real-world dime...
