在现代电子工业中，由于电子技术的快速发展，印制电路板（PCB）在各个领域得到了广泛应用。同时人们对PCB的质量提出了更高要求，因此自动光学检测（AOI）逐渐在PCB检测中得到应用。由于圆形图像在PCB板中有着广泛的存在，因此讨论了一种基于Hough变换的PCB板中圆形图像的检测，为AOI检测圆形图像提供了一种方法。通过仿真，给出了原理性试验结果。

With the development of electronics technology in the modern electronic industry,printed circuit board(PCB) has been widely used in various fields,and at the same time,higher quality requirement of PCB is put forward. Therefore,auto-matic optical inspection (AOI) is gradually applied to the detection of PCB. Because the circular images exist extensively in PCB,a method to detect the circular images in PCB with fast Hough transform is discussed. It provided a new method for AOI. The theoretical experiment results got by the simulation are given.
