摘要
针对目前印刷电路板工业高速发展的生产要求,设计了基于图像处理的印刷电路板质量检测系统总体结构,阐述了基于图像处理检测系统的工作原理,讨论了图像采集单元中扫描仪的选择,以及扫描仪驱动的设计;讨论了图像处理单元中的图像去噪,图像分割、图像识别算法,运用图像差分运算方法完成了对缺陷的检测。实验结果证明使用该方法能够简单、快速、有效地识别出PCB板上断路、短路和缺损缺陷。
The structure of PCB Quality Inspection System Based on Image Processing Technolgy is designed to meet high speed of manufacture requirement in PCB industry.the paper discusses the image acquisition unit,the choice of scanner,and scanner-driven design;concludes with a discussion of the image processing unit in the image denoising,image segmentation,image recognition algorithm,using the image difference algorithms for defect detection to complete.Simulation results are achieved in the Matlab programming environment,experimental results show that the method can use a simple,fast and effective way to identify the PCB circuit,short circuit defects and defect.
