Abstract
A method of obtaining graphical information from a single-or multi-page document printed on a hard media where reading out of the position of the document elements is performed by using a method of volumetric scanning of a document (even closed) is described. Processing of scanning results, comprises joining up the separate scanning layers scanning results, removing noise, correction of document image orientation, dividing information into portions relating to separate pages, is performed after reading the information. Then text information recognition contained in the graphical file is performed. Information may be read out by using methods of magnetic resonance scanning, supersonic scanning, X-ray scanning etc. The results of scanning in electronic form may be stored for further transmission thereof on a medium or via communication channels to a distant location for recognition. A device for realization of the described method is also disclosed.
