A fast recognition method of the 2D-Barcode based on digital image mode

    Abstract
  • The application of PDF417 2D Barcode based on image mode is restricted in practice due to the limitation of its recognition speed.A new method based on measuring parallel marginal distance is proposed in this paper,the logical value can be determined by measuring the distance of two resembled borders of adjacent elements and therefore spare the strenuous marginal measuring.Experimental result shows this method can greatly enhance the recognition speed of PDF417 2D Barcode.
