description The invention relates to a method for correcting flatness defect of finish rolling outlet strip steel. The method is used for correcting and accuralizing straightness defect data, and comprises the following steps: carrying out data detection and curve fitting; determining typical positions along the width direction of the strip steel, and determining the straightness of each typical position according to the fitting function; determining a discrimination coefficient of edge error discrimination according to the straightness of each typical position; determining and generating an error type according to the straightness of each typical position, the discrimination coefficient and the deviation of a width gauge at the finish rolling outlet; and according to the error type, carrying out error situation judgment at each moment, establishing respective correction processing according to judgment results, and outputting flatness defect data after strip steel correction based on different correction processing.
