摘要
本文以应用最广泛的PDF417二维条码为例,在对条码符号结构及编码原理研究的基础上,探讨完成二维条形码识别的软件算法实现。整个识别算法由图像预处理、图像校正和译码三部分组成。实验结果验证该方法有效,软件识别系统性能稳定,为二维条码的识别提供了一条有效的途径。
Used the PDF417 for example, after analyzing structure and coding principle of two-dimensional bar code, we set up the software algorithm of two-dimensional bar code recognition. The entire recognition algorithm is composed of image pre-procossing, image correction and decoding algorithm. The method is effective by the experimental results, the software recognition system is stable, provides a effective way for the recognition of two-dimensional bar code.
