Rating System of the Nickel Coating Corrosion Protection Grade Based on Image Processing

为了能够准确地得到镀镍涂层腐蚀"保护"等级,利用计算机图像处理技术对镀镍层腐蚀图像的腐蚀特征进行检测分析。对镀镍层腐蚀图像采集、图像预处理、图像二值化、腐蚀特征点面积测量进行讨论,给出镀镍层腐蚀特征检测分析图像处理的算法,同时利用MATLAB工具箱对图像处理过程进行仿真试验,最后根据镀镍层腐蚀特征点面积计算镀镍层腐蚀"保护"等级。该方法为镀镍层腐蚀"保护"等级评定提供新的依据。

In order to find the corrosion protection grade of the nickel coating exactly, the computer image processing techniques were used to detect corrosion features in nickel coating. The methods included the nickel coating image collecting, image preprocessing, image binarization, area calculation of corrosion features in nickel coating , the al- gorithm of computer image processing on corrosion protection test was studied, and simulative experiment on the algorithm based on MATLAB was introduced, then the corrosion feature area parameters was used to calculate corrosion protection grade. This method provided a new basis to nickel coating protection grade rating.
