SYSTEM AND METHOD FOR SCANNING AND COPYING Russian patent published in 2009 - IPC H04N1/00 H04N1/409 

FIELD: physics, image processing.

SUBSTANCE: invention is related to systems and methods for scanning and copying with correction of distortions. Result is achieved by the fact that scanning and copying system comprises the following components connected to each other by means of data bus: scanner, the first camera, the second camera, processor, program memory, data memory and external device, moreover, scanner has bottom layer, on which object is placed and along which object is scanned, the first and second cameras are installed at opposite lateral sides of scanner across object bending line in binding, and lenses of cameras are arranged at the lateral side of object, directly across binding ends, besides cameras are arranged with the possibility to produce object pictures from the lateral sides in the area of pages curve near binding, program memory comprises facility for establishment of correction made with the possibility to establish parametres and method of image correction, processor has module of distortion correction made with the possibility to create three-dimensional model of scanned object surface on the basis of data that characterise shape of object page curve near binding, analysis of each scanned line of object image, and when required, correction of distortions in each scanned line with application of scanned surface three-dimensional model data.

EFFECT: improved accuracy in definition of object distortion areas near binding.
