Zhi Liu, Xingbo Guo, Cui Chong · 2012
In order to improve the efficiency and effectiveness of 2D barcode detection algorithm under complex background, detection algorithm for Data Matrix 2D bar code based on regional features analysis and locating method of line Snake algorithm is presented in this paper. Firstly, the region which contains L- type barcode border is selected by analyzing the features of each region. Secondly, the barcode border is located by using line Snake algorithm, and the four vertices of the barcode are fitted. Finally, the barcode is rectified by using transmission shift. Experiments show that the detection algorithm of 2D barcode has good performance, and it is better than traditional barcode detection algorithm. It has strong anti-interference capacity, and can satisfy the needs of real-time on cell phone.
