In optical character recognition (OCR) works, the edge of book material can produce surface deformation, and these parts can be hard to recognize by software. An algorithm was proposed to solve the problem. The main purpose of the algorithm is to flatten the deformation text information. The mapping information between raw materials and the flattened materials was obtained through cutting the text into grid and fitting calculation of material deformation function of the curvature. Then the flattened information was regenerated. A new algorithm was proposed which can  perform well but doesn’t need too much calculation. The algorithm was tested and proved under different situations. The efficiency was greatly improved, and recognition rate was significantly increased compared with the raw materials. The algorithm does not require complicate device to gather data, and most existing scanned data can be used for correction process.
