一种基于图像方式的二维条码快速识别的方法

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

    摘要
  • 摘要: 基于图像方式的PDF17二维条码识别由于识别速度的原因,应用中受到限制,本文提出一种平行边距测量法,对符号中相邻元素的相似边之间的距离的测量来判别字符的逻辑值,可以免去占用大量时间的边缘检测,从而显著提高译码速度.实验表明该方法能显著提高PDF17二维条码的识别速度.

     

    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.
