I'm looking at calculator angle and I think I understand it. but has anyone used it before to position an element to match the live feed in rotation?
I did use it a few years ago, but we used IR LED's to track the live feed. You need 2 points to calculate the angle and without having eyes++ seeing two points I would not know how to calculate the angle.
yes, I have two retro-reflective tape markers and infrared feed. thanks
