FIELD: information technology.
SUBSTANCE: method is carried out by detecting symbol images in the scanned image containing a text; performing pre-processing of the symbol image for each detected symbol image for determining the graphemes associated with the symbol standards, the calculated similarity level of which with the normalized symbol image exceeds the threshold similarity level, and sorting the graphemes determined by the calculated similarity level; and using the sorted certain graphemes to generate the symbol codes for the symbol images that are stored in one or more memory devices.
EFFECT: increasing the efficiency of optical symbol recognition.
