Projector Calibration Specs #1

Open lindseysMT opened 1 year ago

lindseysMT commented 1 year ago

I have a question regarding the projector calibration - is there any specs regarding the board or charuco markers required for the dot calibration? I've tried multiple ways, and usually get the error that it cannot find any dots on the board. Here is an example snippet of the clarity on the board - just curious if there's some specification that would help getting the circles to be registered:

Board 
Error: False
NO CIRCLES FOUND, ABORT

It's been a while since I tried this out. I remember having to adjust the circle size and brightness. It appears that your circles look a little blown out and not entirely round from the camera's perspective.

Thank you so much for responding! I'll work on the projector settings and reduce the overall blow out / projector angle to the whiteboard. Thank you!
