【摘要】 在FPC (柔性印刷电路) 的视觉检测系统中, 快速准确的瑕疵识别规则和算法是实现实时在线检测的关键。该文针对FPC线路的瑕疵识别问题, 在研究已有瑕疵识别规则的基础上, 设计了一种多模板参考比对法。该方法能针对不同线路瑕疵的特点, 分别予以处理。实验证明, 该方法减少了漏检率, 提高了准确度, 扩大了检测范围, 是一种颇有价值的思想。更多还原

【Abstract】 In FPC visual inspection system, fast and exact recognition rules and arithmetic of defect is crucial for the realization of on line inspection. Based on the research of existing rules, a new method for the FPC line defect recognition is advanced, named multi-template reference contrast.This method can distinguish most kinds of defects, and find out them respectively. It’s been proved by experiments that this method has lower misdetection frequency, higher veracity, and wider detecting scope. In a word, it’s a valuable idea.更多还原
