'ArUco markers, why does the pose change when I change image resolution?
I use this reference https://automaticaddison.com/how-to-perform-pose-estimation-using-an-aruco-marker/ to estimate pose of a marker.
When I obtain cam matrix and distortion matrix I used the full camera resolution.
However, when I change the resolution (image size) before pose estimation, I am getting different results. I am not sure why and which resolution would be correct to use.
Should we always use the same resolution as what was used for camera calibration?
I expected the pose to be somewhat independent from image size other than minor changes. Any thoughts?
