摘　　要：设计了一种可在ADI低成本DSP(小内存平台)上实现的QR码识别系统,并在以BF592为核心的硬件平台上实现。系统基于图像处理方法,在32 KB的数据空间内实现了二值化压缩并行的图像采集时序、多个方向扫描对QR码进行定位、采样解码等功能。经测试,该系统取得了良好的识别效果。A QR code decoding system which can be implemented on ADI low-cost DSP is designed. The system is based on image processing and implemented on the hardware platform with center processor BF592. The whole system is running within 32 KB data memory, including image capturing and displaying, image storing and thresholding using paralleled timing, QR code detection with multi-direction scanning, sampling and decoding and so on. The experimental result shows the good performance of the system.
