摘要:

介绍表面贴装LED全自动编带机基于数字图像处理技术的视觉检测系统,探讨采用明度检测的方法对型号为5050六角正面发光贴片LED进行缺失检测。该检测方法首先将采集的芯片图像进行
灰度化处理,再通过中值滤波进行去噪,然后检测无料和有料2种情况下的明度值,计算明度偏差平均值且将此值定为临界值,检测过程中明度值大于该临界值时载带有料,反之则载带无料。该检测方法
算法简单、效率高,检测结果表明了该方法的可行性和正确性。

Abstract:

 This article describes the automated surface mount LED of the taping machine based on digital image processing’s vision detection system technology. The system
uses lightness value image production method to identify missing of the model of 5050 six angle front light emitting diode. Firstly, the detection method is to deal with image
by gray processing in the computer, then to deal with the noise through the median filtering, and then to detect lightness value of carrier band with or without material,
calculates the average deviation of lightness and this value would be a critical value, so the lightness value is greater than the critical value in the process detecting when
carrier band with material, the opposite carrier band without material. This detection algorithm is simple, high efficiency, detection results are given in the article, and the
feasibility and correctness of the method were validated theoretically and practically.
