摘要
条形码在日常生活中具有广泛的用途,但常用的一维条形码存在信息含量小的缺点,已不能满足实际的需要,因此,二维条码技术应运而生。本文研究了关于Data Matrix二维条形码自动识别的相关技术,包括对二维条形码图像的预处理、图像的提取及其译码等,并通过实验模拟得到了很好的实验结果,实现了Data Matrix二维条形码的自动识别过程。
The application of bar code is extensive in daily life. One - dimensional bar code is universial, but it can not meet the real demands owing to its defect of small information content. Thus, the two - dimensional bar code technique is occurred. This paper studies and discusses some interrelated automatic recognition techniques about Data Matrix two dimensional bar code, including the pre - processing, the extracting and decoding of two dimensional bar code images, and so on. A good experimental result has gained by imitative experiments, and the process of automatic recognition on Data Matrix two-dimensional bar code is realized.
