摘　　要：二维条码长期暴露于印刷品表面,很容易受到污损破坏,为了达到预期的识别效果,除了要设计合理条码结构外,还需要采用一种纠错能力强的纠错算法。为此,分析了QR码的结构组成以及RS纠错码的编译算法及原理;并通过实例对RS码在QR码中的编译码算法及过程进行了研究,研究结果表明RS码在QR码的编译过程中能够达到快速、准确的识别效果。The two-dimension barcode printed on the surface is susceptible to be defiled and damaged for a long time.In addition to rational design of bar code structure,the error correction code is more important in the identification.So this paper introduced the 2D barcode Quick Response（QR）＇s structure,encoding,decoding principles and national standard.An explanation of the RS code＇s algorithm was given by making use of the RS＇s encoding and decoding algorithm in the QR Barcode.Through the application of the RS code,the QR barcode can be quickly identified and correct the error generated in the transmission of the QR barcode.
