Abstract :
Based on DataMatrix 2D barcode, a DataMatrix mutant barcode which was also a matrix 2D barcode was designed. A distorted image of a mutant barcode was obtained by simulating actual environment. The barcode area in the image was acquired by barcode localizing. After the barcode area being analyzed, these barcode characteristic parameters were abstracted and the distorted image fitting formula was gained by exercise, which set up the correspondence between distorted barcode image point coordinates and the standard one. Thus the 01 code of mutant barcode of the distorted image can be abstracted. The implicit information in the 01 code can be decoded with DataMatrix decode method. From the actual testing result, the barcode recognizing speed is faster than others by this way, and this method was robust.
