摘要
利用自动视觉检测系统 ,实现对高速SMT生产线贴片质量的在线检测。详细介绍了视觉检测系统的LED光源 ,分析了使用此光源的优点 ,提出用两种灯光 ,分两次扫描PCB板 ,得到两幅图像 ,以增加图像的信息量 ,减少误判。给出图像采集的具体措施和图像处理的常用算法 ,并给出了应用算法的具体实例。此系统具有开放性 ,可根据实际需要增加算法 。
The on-line inspection of mount quality for high-speed SMT assembly is realized by use of automated visual inspection system. The LED luminous source in the system is introduced, the benefit of which is analyzed. Two kinds of lighting are used to get two pieces of images by scanning PCB twice, which can increase the information in the image and decrease the misjudgments. The method of image collection and the algorithm of image processing are put forward. Meanwhile, the example using the algorithm is given. The system is open, and the misjudgments can be further reduced by adding the algorithm satisfied with job sites.
