Patent ID: 7019713

Claim:
A method for aligning multi-projector display systems comprising the steps of: storing an image pattern description; capturing tiled display test pattern images; using said stored image pattern description and at least one of said captured tiled display test pattern images, identifying a tile array placement and layout; using said stored image pattern description and at least one said captured tiled display test pattern image, performing a tile registration measurement; using said stored image pattern description, and at least one of said captured tiled display test pattern images, performing a dot grid measurement to provide measured dot grid positions; using at least one said captured tiled display test pattern images and said measured dot grid positions, calculating a tile-to-camera map; using at least one of said captured tiled display test pattern images and said measured dot grid positions, calculating a camera-to-mural map; and using said tile-to-camera map and said camera-to-mural map to generate control and correction data; said control and correction data being applied to selectively vary alignment of a plurality of projectors by control of respective associated positioners with the plurality of projectors.
