Abstract

Two aspects of electroplated gold that are often inspected on are plating thickness, and verification of gold presence at desired regions. With the later, in-situ reporting is desired. In this work, 8 color spaces - RGB, rgb, I1I2I3, HSI, YUV, YIQ, XYZ, and L*a*b* - were investigated to differentiate between regions with and without electroplated gold. It was found that the r, b, I2, H, U, V, I, Q, Z, and b* color space components provided distinct two level differentiability; while the R, G, and S color space components permitted differentiation at non distinct two levels. It was also uncovered that grayscale imaging would not permit any form of differentiation. The findings here indicate feasibility in using machine vision in tandem with color space analysis for electroplated gold inspection.
电镀金检验
电镀金经常检查的两个方面是电镀厚度和在所需区域金存在的验证。对于后者,需要进行现场报告。在这项工作中,研究了8种颜色空间- RGB, RGB, I1I2I3, HSI, YUV, YIQ, XYZ和L*a*b* -来区分电镀金和未电镀金的区域。发现r、b、I2、H、U、V、I、Q、Z和b*色空间分量具有明显的二级可微性;而R, G和S色彩空间成分允许在非明显的两个层次上进行区分。还发现,灰度成像不允许任何形式的分化。本文的研究结果表明,将机器视觉与色彩空间分析结合起来进行电镀金检测是可行的。
