摘要
为了降低二维条码地使用成本、增加信息流容量,在深入对比研究汉信码和Qr Code的基础上,改进了4版本以上汉信码符号取样网格建立算法,更正了功能信息纠错编码,构建了汉信码生成及识读工具。实验证明算法可行、可靠;构建的工具高速、准确。最终给出了汉信码在农产品质量管理系统中的应用方案。
An algorithm of sampling grid above the 4th version and the RS error correcting of function information was improved, and the Chinese character code generation and identification tool was constructed to decrease the cost of barcode and increase the capacity of information based on the contrast of the Chinese-sensible code and the QrCode. The experimental results showed that the proposed algorithm is feasible and reliable, and the constructed tool can be implemented with high-speed and exactness. An example of the application plan of the new 2D barcode identification tool in agricultural product quality management system was introduced.
