ABSTRACT:
There is provided a method for discriminating a tire class which can improve discrimination grade of the tire class by detecting error of decoding, in case the decoding of a character is erroneous. A train of symbols is composed of a multiple arrangement of discrimination symbols, and the discrimination symbols are composed of a character code portion that is indicated according to existence of a length and breadth, and a parity check porion indicating truth and falsity of said character code portion with existence of multiple dots. A CCD camera photographs a train of symbols, and the train of symbols in the photograph is made of two dimensional image data; according to a control unit, the existence of each discrimination symbol dot at the train of symbols of the image data is recogonized, and the character code is decoded due to the length and breadth arrangement of the character code portion of the discrimination symbols. Simultaneously, the truth or falsity of a decoded result of the character code is judged by arrangement of the parity check portion dot of said discrimination symbols.
