I have multiple pan tilt spot lights and want them all to point at the same real world location. A location that keeps one changing.
I assume there must be some sort of 3d world calibration method, similar to how 2 camera spaces can be calibrated via homography. But when I calibrated cameras in the past it was always just to a plane; like the floor.
But to have the beams of multiple lights hit the same spot in a 360˚ spherical world surely be a different beast.
I have a 3d simulation working where all simulated light fixtures follow the same 3d point. But real world lights are never setup as perfectly and might not have the perfect relation to each other and the space.
Any advice would be appreciated. Thanks.
