Any Recommendations for a COLMAP alternative? about neuralangelo HOT 4 CLOSED

Hi @x-CK-x

Thank you for your interest in the project.

For a turntable, you could calibrate your camera intrinsics with a checkerboard and fix it during the SfM process. I think this is the most sensible thing to do. Alternatively, you can put markers on the turntable (e.g. ArUco markers) and use PnP to estimate the poses. As you have a very controlled setting, it probably makes more sense to leverage the additional information that you have instead of relying on SfM.

I hope these help.

I'm not exactly sure if COLMAP were suitable for this type of capture setup. I can imagine it to work to some extent if the background were absolutely clean (e.g. white) and no background features could be matched, but then the lesser amount of remaining features on the foreground object would likely make SfM less robust. We found COLMAP to be reliable for most of our use cases.

COLMAP is really difficult to compile, install, and run on cloud virtual machines with no display. Are there COLMAP alternatives that are cloud-friendly? Are there ways to run COLMAP on a cloud virtual machine?
