图像处理技术在条形码识别中的应用研究

Application Research of Image Processing Technology in Barcode Recognition

将图像处理技术引入到条形码识别中能够提高条形码识别的准确率和效率,因此本文对图像处理技术在条形码识别中的应用开展研究。首先,详细介绍了条形码的编码规则与识别原理;其次,以EAN码为例介绍了该类编码的结构组成,并简要介绍了宽度测量法、平均值法和相似边距离测量等条形码译码方法的基本原理及优缺点;最后,给出了基于图像处理的条形码识别方案,包括条形码图像的采集和条形码信息处理。

Introducing image processing technology into bar code recognition can improve the accuracy and efficiency of bar code recognition.This paper studies the application of image processing technology in bar code recognition.Firstly,the coding rules and recognition principle of bar code are introduced in detail;Secondly,taking ean code as an example,this paper introduces the structure of this kind of code,and briefly introduces the basic principles,advantages and disadvantages of three bar code decoding methods,such as width measurement method,average value method and similar edge distance measurement;Finally,a bar code recognition scheme based on image processing is given,including bar code image acquisition and bar code information processing.
