Abstract: In order to promote the application of two dimensional barcode in embedded systems, this paper designs a QR code recognition system. The system is based on S3C6410 development board and WINCE platform. Firstly, this paper briefly introduces the basic structure of QR code. And then, it analyzes the gray level transformation, median filter and binarization of QR code image, and studies the location and rectification of QR code. The last but not the least, it emphatically discusses the problem of real-time image acquisition. After being used, the system shows good stability and considerably high barcode recognition rate.
