Identification code recognition system and method

An identification code recognition method, comprising:

• receiving an identification code (ID code) corresponding to a workpiece from a manufacturing execution system (MES);
• obtaining a first image of an entire area of the ID code engraved on the workpiece;
• obtaining a recognition result value of the first image through first image analysis logic, wherein the first image analysis logic compares the first image with a reference pattern;
• comparing the recognition result value with the ID code received from the MES to determine whether misrecognition occurs;
• when it is determined that at least one character of the recognition result is misrecognized, obtaining a second image of a partial area including at least one misrecognized character;
• obtaining a partial correction value of the second image through second image analysis logic, wherein the second image analysis logic compares the second image with the reference pattern;
• and
• obtaining a final result value by removing the at least one misrecognized character from the recognition result value and by combining the recognition result value and the partial correction value.
