摘　　要：在某些复杂的生产线上,传统的LED条码扫描方法因识别成功率无法保证而使其应用受到制约,基于光学图像处理的条码识别方法,由于采用高分辨率图像结合先进的图像处理算法而具有明显优势。本文介绍Halcon软件中一维条码识别算子的基本含义和使用方法,主要包括条码识别程序采用的编程架构,条码的尺寸、方向、类型、校验位的设置方法,扫描线的设置方法等,对所设置的参数进行读取的方法,还包括数据结构如轮廓、条码字符串等的应用方法。On some complicated production lines, applications of the traditional LED based bar-code scanners are restricted, be- cause of their unsatisfying recognition rate. While CCD cameras give high-resolution of bar-codes and with the advanced process- ing operators, they give better recognition results. This paper introduces the skills and applications using bar-code recognition op- erators in Haleon software, including the architecture of the procedure, the dimension, orientation, type, and check digit of the bar-code, and setting method for scan-lines. The methods to read the set parameters, and the application skills of the data struc- tures such as the contour and the bar-code are also presented.
