【摘要】 本文介绍了利用拍照手机实现对PDF417二维条形码识别的一套完整解决方案,提出了适合手机组成结构的PDF417二维条形码图像识别算法:在极为有限的手机处理器资源下,针对手机摄像模组普遍存在的光学退化特性提出了图像复原的方法;针对手机应用处理器的特性设计了计算量小、内存开销少的条形码图像识别算法。实测表明,对中小规模的PDF417条形码图像的识别速度和准确度完全达到实用的水平。更多还原

【Abstract】 This paper introduced a solution method of PDF417 barcode recognition using a camera equipped Smartphone According to a physical project work..The paper provides an algorithm which solves the optical degradation problem and recognition problem use a very low processor resource assumption.A part of testing result shows that the program was enough to deal with the PDF417 barcodes which has a middle complexity or less.更多还原
