摘要
为准确计算金属材料表面腐蚀孔的参数,以高压阳极铝箔在直流电侵蚀下形式的表面腐蚀孔为例,提出了一种根据腐蚀孔形状特征设计的矩形模拟算法。利用计算机图像处理技术,提取腐蚀并孔轮廓上的特征凹点,将这些点根据算法进行矩形模拟,从而达到在试样腐蚀孔图像上用矩形块来模拟腐蚀孔的目的。通过试验证明该算法有较好的效果,可为下一步的分析研究工作提供依据。
In order to compute the parameters of etched hole on metal surface accurately, as a example of etched holes on high voltage anode aluminum foil by DC, a rectangle simulation algorithm was designed based on the shape feature of the etched area. With the use of computer image processing techniques, the concave points were extracted on each hole＇s contour and used to construct rectangles on the sample images to simulate these overlapping hole. Acceptable results of experiments had been obtained, further studies and analyses were based on the simulation results.
