基于手机平台的DataMatrix2维条码识别
DOI: 10.11834/jig.20100216
Keywords: 2维条码,手机,Data,Matrix,反模糊,反透视变换
Abstract:
传统的条码图像采集和识别是通过工业扫描枪。近年来,随着移动增值业务和3G技术的发展,2维条码在手机设备的应用中得到飞速发展。以DataMatrix为例，研究了基于嵌入式手机设备的2维条码识别技术。首先根据DataMatrix条码的特点，给出了一种基于链码跟踪和线段检测的快速DataMatrix检测算法。接着分析了条码信号经过点扩展函数卷积后的降质模型，并利用维纳滤波对条码信号进行反模糊滤波。最后,针对透视畸变的现象，设计了一种适合于嵌入式手机设备的快速反透视算法。实验结果表明，提出的识别算法具有优秀
