摘要
针对日常生活中常见的QR码应用,基于蜂鸟E203 RISC-V处理器架构设计了一款QR码识别系统。通过对系统内部关键组成单元进行定制化的硬件设计以及配套软件算法的实现,完成整体系统环境的搭建,并通过了系统功能验证。另外,本文还对不同情形下的QR码进行相应的测试。测试结果表明,在系统工作频率为32 MHz时,平均识别耗时为705 ms,正确识别率为96%,证实了该系统的可行性。
Aiming at the common QR code application in daily life,a QR code identification system is designed based on the Hummingbird E203 RISC-V processor architecture.Through the customized hardware design of the key components of the system,and the implementation of the supporting software algorithms,the construction of the overall system environment is completed,and the verification of the system function is passed.In addition,the QR codes in different situations are tested accordingly.The test results show that the average identification time consuming is 705 ms and 96%,which confirms the feasibility of the system.
