用于印刷电路板缺陷检测的光学视觉

OPTICAL VISION FOR DEFECT DETECTING OF PRINTE CIRCUIT BOARD

本文提出了一种利用光学形态变换探测印刷电路板缺陷的新方法。以非相干光学相关器为基础，构成了一个实现印刷电路板微小缺陷检测的形态变换光学视觉系统给出了原理性实验结果。

In this paper,a new method for defect detecthg of prinited circuit hoard (PCB) using morphological transformations is proposed;Based on an incoherent opticalcorrelator,a morphological optical vision system for small-area defect detecting of PCB isco nstituted. The proof- of- principle experimental resuits are given。
