Hello,
I have a system with a camera looking vertical on a table and there is a robot with a target. I already have the camera calibrated and i have the extrinsic and intrinsic values and get a rectified image.
Now i compute the mass center of the target and get its values (u,v).
My question now is how do i get the real 2D (x,y) world coordinates? I don't need the z value because it has always the same z value (10 cm). Could anyone explain it to me please?
