We describe a calibration and rendering technique for a projector array that can render a seamless rectangular image on a planar surface. The projectors utilize an attached camera to automatically compute the relative pose among them. We describe calibration of the full system using planar display surface to achieve registration and intensity blending of overlapping images. We present an efficient rendering method to pre-warp images so that they appear correctly on the screen, and show experimental results.
