Method for automatically correcting error of character recognition result

The invention discloses a method for carrying out automatic error correction on a character recognition result, which comprises the following steps of: acquiring predicted character information in an image to be processed and standard character information in the same scene; searching candidate common subsequences in the predicted character information and the standard character information; traversing the candidate common sub-sequence, judging whether the candidate common sub-sequence is a reasonable sub-column or not, and if yes, ending traversing; filtering and filling the predicted character information by using the common subsequence to obtain processed predicted character information; and correcting the predicted character information according to the processed predicted character information, and outputting correct character information. The method is suitable for post-processing an OCR detection recognition result, and can effectively solve the problem of result errors caused by character false detect
