随着计算机技术和信号处理技术的蓬勃发展，条形码尤其是二维条码在各个领域中的使用范围越来越广，为了保证对二维条码中所含信息识别的准确性，需要对条码的识别算法加以研究。本文以PDF417码为例，在普通的摄入环境下采集到干扰比较大的图像，利用MATLAB通过滤波、分层等算法对这样得到图像进行的一系列处理，最终得到图像的源代码。在处理过程中，保证了图像解码的准确性，减少了在普通摄入环境下可能产生的图像畸变、噪声干扰、运动伪影等干扰对条码识别的影响。

Along with the vigorous development of computer technology and signal processing technology,barcode,especially the two-dimensional barcode,is used more and more widely,in order to ensure the accuracy of the recognition of two-dimensional barcode,the recognition algorithms should be learned.Using an ordinary camera equipment, a PDF417 barcode image can be got with a lot of noise points,through the image processing which is realized by the MATLAB, the source code of the image can be got.During the process,different algorithms such as filtering , stratifing can be reduced to ensure the accuracy of the image decoding,and a series of problems which are caused by external disturbance such as image distortion,noise,motion artifacts can be reduced too.
