摘　　要：使用数码相机、手机、电脑摄像头等通用摄入设备采集的条码图像普遍存在有高光区，阴影，低分辨率，散焦模糊等缺点，如果不能得到较高质量的还原和修复图像就无法对其进行准确解码或者根本无法解码。本文以摄像头拍摄的有散焦模糊等噪声影响的QR码图像为例，研究了在一定复杂度限制的条码图像处理技术，提出了完整的预处理算法。2D bar code which is reached by camera, cell-phone and shoot-caput generally exists high-light area, shadow, low resolving power, illegible effect. If high-effect deoxidized and rehabbed picture can＇t be reached, it will can＇t be nicely decoded or decoded at all. The article discusses QR code which is shot by shoot-caput and has illegible effect, researches barcode-picture which is limited by some complexity, and brings forward orbicular pretreatment arithmetic.
