摘　　要：提出一种PDP电极缺陷自动检查系统的设计方案,系统分为机械部分、数据采集部分和图像处理部分。机械部分为整个系统提供扫描平台。数据采集部分由FPGA控制线阵CCD数据的采集与传输,并通过USB2.0接口将数据存储到PC机上。图像处理部分通过介绍一种简单的图像处理方法,在PC机上实现了简单的PDP电极缺陷的识别。本系统可及时、快速、准确地查找PDP电极缺陷的位置及其种类。A design of an automatic system for inspecting PDP electrode defects is presented in this article, which includes three parts：mechanism, collection and transfer of data and image processing. Mechanism provides a scanning platform for the entire system. Collection and transfer of data, are controlled by FPGA to implement the data collecting of linear CCD and transfer the data to PC by USB2. 0 interface. And image processing inspects PDP electrode defects on a PC through a simple image processing method. This system can be timely, rapidly, and exactly to find the types and locations of the PDP electrode defects.
