FIELD: physics.
SUBSTANCE: method for eliminating the curvature of the document image includes: determining the boundaries of, at least, the fragment of the document in the original image, determining the plurality of symbols in the document, determining some of the symbols as a plurality of word fragments, creating a plurality of the first polynomials, creating the second polynomial, determining, at least, one expansion coefficient for the first text line, displaying the parts of the original image by, at least, one processing device along the first text line to the new position in the corrected image based on the second polynomial and the expansion coefficient.
EFFECT: improving the accuracy of eliminating distortions.
