摘　　要：条码技术是实现物流信息自动采集与输入的重要信息技术,二维条码是用某种特定的几何图形按一定的规律分布的黑白相间的图形记录数据符号信息的。系统采用基于SOPC技术来实现二维条形码识别的方法。该方法是基于一种系统级电路,通过QuartusⅡ和SOPC Builder实现对此系统的定制。该识别系统能够快速准确地识别二维条码,测试结果表明本系统二维条码平均识别率达97.7%,平均耗时60 ms。Bar code technology is a logistic information collection and input technology.Two-dimensional bar code is a particular geometric figure according to certain rules of distribution of black and white alternate trip to represent graphic record data symbol information.The system uses a method based on the SOPC technology to achieve the two-dimensional bar code recognition.The system design method is based on a systematic level circuit,through the Quartus Ⅱ and SOPC Builder to realize this system custom.The recognition system can quickly and accurately identify the two-dimensional bar code,and test results show that the system is a two-dimensional barcode average recognition rate of 97.7%,the average time of 60 ms.
