| 摘 要： | Datamatrix是矩阵式二维条形码之一,由于其尺寸小、保密性好、纠错能力强而广泛使用在工业、数据安全及其他行业.在实际应用中,由扫描设备得到的二维条码图像通常有噪声、污损及背景干扰,并具有平移、旋转.为提高实际应用中的正确译码率,通过预处理和两次图像定位,从实际图像中分割出Datamatrix图像,再从中读取数据,进行正确译码,完成对Datamatrix的识别.

| Abstract: | Datamatrix is a kind of 2-D matrix bar code.Because of its small dimension,good security and high ability of error correction,it has been widely used in industry,data security,and other areas.In application,the images always include noise,blurs,background,or geometric transformation.A method of recognizing Datamatrix is presented.By preprocessing and twice-localization,Datamatrix symbol is segmented from the image and its data are obtained,then decoded. |

| Keywords: | Hough transformation image localization image rotate Datamatrix error correct |
