【摘要】 在印制电路板 (PCB)的自动检测过程中 ,已经注意到准确的定位在生产过程中对自动安置电子器件是非常重要的。骨架是图像几何形态的一种重要拓扑描述 ,利用骨架表示原始图像 ,在保持图像拓扑特征的前提下 ,减少了冗余信息。本文通过介绍一种通用的细化算法 ,进而引入数学形态学的改进细化算法 ,利用提取的骨架对电路板进行定位。经比较 ,运用形态学方法的细化结果有着较好的定位效果更多还原

【Abstract】 In PCB(Printed Circuit Boards)automatic inspection processes,it has been noted that reliable accurate marker registration is essential for automatic placement of electronic components during manufacturing.Skeleton is an important topological description of the geometric properties of image.Based on the premise that keeps topological characteristics of image,by using skeleton to describe original image the redundant can thus be reduced This paper firstly introduces a general thinning algorithm,and then a improved thinning algorithm of mathematical morphology is introduced finelly use the skeleton to locate the PCB.By comparing,the thinning results of using the morphology method have get good location results.更多还原
