An image pattern description is stored and tiled display test pattern images
are
captured. The stored image pattern description and at least one captured tiled
display test pattern image are used to identify a tile array placement and layout;
a tile registration measurement; and a dot grid measurement providing measured
dot grid positions. At least one captured tiled display test pattern images and
the measured dot grid positions are used for calculating tile-to-camera maps and
a camera-to-mural map. The tile-to-camera maps and the camera-to-mural map are
used to generate control and correction data.
