摘    要:针对现有农产品质量安全追溯中成本高、追溯设备便携性差等问题,设计了基于手机二维条码识别的农产品质量安全追溯系统。阐述了系统的架构和主要功能设计,并对系统采用Nokia 3款手机为实验终端在手机摄像头与条码不同的距离处进行了最佳识别距离、识别时间、识别率和准确率的测试,食品包装袋和标签纸上条码平均识别时间分别为7.3 s和5.1 s,平均识别率分别为67.8%和75.6%,准确率均可达到100%,识别的最佳距离为10 cm左右,最短识别时间仅为6.4 s和3.4 s。测试结果表明,该系统可以方便用户快速识别产品的二维条码标签,为消费者提供了一种新的追溯手段。

关 键 词:农产品质量安全  可追溯系统  手机二维条码  QR码

Abstract:Aiming at the poor portability of devices,high cost of the existing traceability methods for agricultural products quality and safety,an agricultural products quality and safety traceability system based on two-dimension barcode recognition of mobile phones was developed.The architecture and main function design of the system were illustrated in detail.Through the tests of the best recognition distance,recognition time,recognition rate and accuracy rate on the system using three types of mobile phones from Nokia in the case of the mobile phone cameras various distances away from the barcodes,the average identification time for barcodes of food wrappers and tagboards was 7.3s and 5.1s respectively,average recognition rate was 67.8% and 75.6% respectively,and accuracy rate were to 100%.The best recognition distance was about 10cm,identification time for barcodes of food wrappers and tagboards was only 6.4s and 3.4s respectively.The test results show that users can recognize two-dimension barcode labels attached on products quickly and conveniently through the system,and it will provide a new traceability means.
Keywords:Agricultural products quality and safety  Traceability system  Two-dimension barcode of mobile phones  QR code
