Using Larger Aruco Markers

[spencervoiss]

Hi,
Thanks for building such a powerful tool for dataset generation. If I can get it work right, this software will make my life significantly easier. I'm running into some issues with registering a large target. I'm trying to generate a dataset for a model plane with a wingspan of 2.1m, but it's not registering properly. I've scanned a small target with moderate success, but the bigger target seems to be confusing the algorithm. I've attached photos of a successful registration (the small plane) and of the unsuccessful registrations (the big plane).
My hypothesis is that the problems are resulting from the Aruco markers being too small for the cameras to pick up at the distances required to get the whole target in the shot. What all would I need to change in the source code for it to work with larger Aruco markers (perhaps 8"x8" per marker)? Do you think that enlarging the Aruco markers would solve this issue?
