摘要

结合数字图像技术和色度学相关原理，针对腐蚀过程涂层表面出现的色彩变化，建立了基于颜色特征的涂层材料腐蚀性能检测方法。利用建立的腐蚀形貌采集系统，对现场暴露不同时期的涂层试片进行采集。采用HSV颜色空间对腐蚀试样表面的变色程度进行描述，提出颜色特征参数CP，实现对涂层腐蚀试样外观变色的计算机判别，为材料的腐蚀特征检测提供了新的方法。

Abstract

This paper examines an analysis method of corrosion surface damage of coating materials by using the digital image processing technology and related theory of colorimetry.The corrosion morphology image acquisition system was established

and was used to capture the corrosion morphology of coating specimens

which were exposed in the field exposure station.To describe the discoloration of corrosion surface damages

the HSV color model was used.The Euclidean distance between uncorroded image and corroded image was extracted as color characteristic parameter. A method for automated identification system of discoloration of corrosion damages was developed based on this analysis

and could be an important step in the direction in corrosion inspection.
