Evaluation of Copper Strip Corrosion Test Based on Color Features
-
摘要: 铜片的腐蚀评级是根据文字描述或与标准色板比较得出, 是一种基于颜色特征的腐蚀评价, 由于腐蚀的不均匀性造成铜片腐蚀评级困难。针对此问题, 提出一种基于颜色特征的腐蚀评级方法。通过控制拍摄环境, 对获取的图像在CIELAB颜色空间内采用K均值聚类的方式实现特征颜色的提取, 并与标准色板构建的特征库进行比对, 得出腐蚀评级。结果表明, 该方法与目测结果有很好的一致性。Abstract: The copper strip corrosion level is evaluated by color features according to the description or ASTM copper strip corrosion standards. It is difficult to make the decision because of the inhomogeneity of corrosion. A new copper strip corrosion level evaluation method based on color features is proposed to solve this problem. Firstly, to control the shooting condition; secondly, to convert the image from RGB color space to CIELAB color space and to extract the color features by K-means clustering; thirdly, to match the color features with the color feature database constructed by the ASTM copper strip corrosion standards to get the copper strip corrosion level. The results show that both this new method and the visual method have the similar consequence.
