1. An automatic system for capturing in computational form the image content of an image on a surface, comprising; a) a surface upon which is provided an image; b) at least one camera subsystem for capturing said image in a matrix of image tiles, each of said tiles comprising at least a portion of the image, said tiles each overlapping adjacent tiles, at least one of said tiles including perspective distortion of the portion of the image; c) a processor for receiving and processing said image tiles to combine said tiles to determine a complete computational image corrected for perspective distortion representing said image, the processor determining an overlapping area in each tile overlapping adjacent tiles, finding a mark in each of said adjacent tiles representing a mark in the overlapping area, and combining said tiles based on said mark to produce a single computational image corrected for perspective distortion representing said image, the processor combining said tiles to produce a single computational image corrected for perspective distortion by: 1) for each two adjacent tiles, determining a region of overlap between a first tile and a second tile; 2) determining at least a mark in said region; 3) finding a projection of said at least one mark at a first surface coordinate location in said first tile image; 4) finding a projection of said mark at a second surface coordinate location in said second tile; 5) correcting perspective distortion between said first and second surface coordinate locations; and 6) writing corrected surface coordinates into a representation of said computational image stored in said memory; and d) memory accessible by said processor for storing data including instructions for said processor and said computational image corrected for perspective distortion.
