1. A method of calibrating a projector system having two or more projectors, with one or more cameras, comprising the steps of: capturing, with the one or more cameras, one or more projected patterns from the projectors in an overlap region on a screen; mapping projected pixels from each projector into a common coordinate system; mapping the common coordinate system to the screen to find a homography between the two or more projectors; measuring a difference between the projected pixels and a projector model generated from the homography and a projector distortion map to yield a displacement field; and selectively applying the displacement field outside of the overlap region.
