摘    要:研究了复杂背景中条码检测定住技术。先分析每个子区域的特征,选出可能包含条码的子区域,然后对子区域进行合并筛选,检测条码所在位置。最后根据Hough变换.找出条码边界.并用双线性插值将条码旋至水平。实验表明文中提出的条码检测定位算法具有很好的性能,优于传统的基于梯度特征的检测算法。

关 键 词:条码  检测  定位  多特征  双线性插值

Abstract:Bar code detection and localization technology is an i mp ortant step in a bar code recognition system. Before its recognition, the bar co de needs to be located by filtering text and other signs on the image. This pape r presents an approach for detection and localization of the bar code. Firstly, the subregions that contain the bar code are found out by multiple features anal ysis. Then after subregions clustering and candidacy test, the bar code is found out. Finally the edge of bar code is located on the image according to Hough t ransform and the barcode is rotated to be horizontal based on bi-linear interpo lation.Experiments show that the algorithm has a good performance and is superio r to the algorithm based on the gradient feature.
Keywords:bar  code  detection  localization  multiple features  bi-linear interpolation
