摘　　要：为了有效开展手机的二维条码业务,研究并设计一种可嵌入各类手机平台的通用型二维条码识读软件系统。选用完全开放的QR(Quick Response)码作为识读的二维码型,规避了国际专利追偿风险。采用一种高效的低复杂度图像预处理算法,并根据这种解码算法,利用VC++编程开发出QR码识读软件,先在PC机的Windows XP下进行测试;将代码优化后,再嵌入Symbian手机软件平台测试。测试结果表明,这种二维条码识读软件在复杂环境条件下有良好的识别率,识别时间也较短,可满足实时性要求。To effectually provide mobile 2D（2-dimension） barcode service, a general-purpose 2D harcode recognitionand and read-our system, which may be embedded into various kinds of mobile phone platforms, was studied and designed. Because the wide open QR （quick response） code is taken as 2D barcode type for recognition, the compensation risk for international patents is avoided. An efficient and low-complexity image pre preprocessing algorithm is adopted for the system. Ac- cording to this kind of decoder algorithm, the recognition software for QR code was developed with VC＋ 4- as programming tool. This software was tested under Windows XP of a PC, optimized in program code, and then embedded into Symhian mobile phone software platform for the final testing. The testing results demonstrate that the system has better recognition rate, spends shorter recognition time and satisfies the real time requirement.
