针对复杂背景下的二维条码定位问题,单一特征提取已很难满足其需要.为此提出一种将图像二值化,然后采用基于数学形态学和kirsch边缘检测的算法滤去图像背景,最后利用投影算法定位条码区域.实验结果表明,该方法简单、快速、准确,很好地满足了实际使用的需要.

For the bar code needs to be located by filtering txt and other sign's on the image,a single feature extraction has been difficult to meet the requirements.In the paper,firstly,the image is processed for binaryzation,then Filter out the background of the image by mathematical morphology and kirsch algorithm.finally,the bar code is located on the image according to projection.The result shows that the method is simple,rapid,accurate,and meet the needs of practical using.
