Abstract:
A method for forming a mosaic image on a display surface with a plurality of projectors, comprising:projecting, for each projector in turn, a single registration image onto the display surface so that a union of the projected registration images forms a polygon; acquiring with a camera, for each single registration image in turn, a corresponding input image; identifying a display area on the display surface enclosed by the polygon; determining, for each projector, a single projective matrix between the display area and each input image, wherein the single projective matrix is a homography; warping, for each projector, a source image according to the corresponding single projective matrix; weighting pixels of the warped source image according to the single projective matrix; and concurrently projecting the warped and weighted source images directly onto the display surface to form the mosaic image.
