摘　　要：提出了一个适合于嵌入式系统的QR Code条码识别算法,采用J2ME技术实现了二维条码识别系统。通过QR Code条码的寻像图形以条码寻像图形对条码定位,利用多级阈值化算法对条码二值化,采用反透视变换算法和双线性插值算法矫正失真条码,有效地解决了条码符号因光线不均、失真变形带来的识别问题。The paper puts forward a QR Code barcode recognition algorithm which applies to embedded system, and accomplishes a two-dimensional bar code recognition system by using J2ME.The system locates a QR Code bar code through the Finder pattern, uses multi-level threshold algorithm to binary bar code, uses the anti-perspective transformation algorithm and the bilinear interpolation algorithm to correct the symbols which are distortion. The system effectively solves the problem of recognitio which causes by uneven lighting, distortion and deformation.
