This, of course, is the key point, and based on the description from
the OP, it probably isn't affine, since affine projections don't do
perspective. So if you take a camera looking at a piece of graph
paper that is slightly tilted, you're going to need something more
powerful than an affine projection.
Yes, the OP needs to clarify. It sounded to me as if it was something
like matching an aerial photo in the camera to a map onscreen, based
on the word "calibration". But I was just guessing.
