摘要:
基于图像处理技术提出了一种无需测量线的涂镀层厚度计算机自动测量方法,并用另一种取多条直线分别测量求平均值的方法对测量值进行验证. 首先,运用MATLAB图像处理软件将用金相显微镜采集到的图像二值化;然后,编程得到二值化图像的投影量曲线以及微分曲线,计算曲线上凹谷区域的实际宽度即得到镀层断面厚度真实值;最后,为了验证结果的准确性,采用在镀层上不同位置画测量线的测量方法求出断面厚度值,比较两次测量的结果. 结果表明提出的计算机测量方法不需要画测量线,能够保证材料完整性,简单可行;只需要一次测量即可得出结果,误差在可接受范围,结果可靠.
Abstract:
A automatic measuring method for coating thickness with no measuring line was put forward based on digital image processing technology. More than one line on the image was measured to get the mean value to validate the method. First, the original image captured by the metallurgical microscope was converted to binary image. Then, the projection curve and the differential curve of binary image were extracted by MATLAB program. The coating thickness was determined after calculating the concave curve width on the projection curve. Finally, to validate the result, measuring lines were drawn in different positions on the image to calculate the coating thickness and the results of the two methods were compared. The results show that the computer measurement method with no measuring line ensures the integrity of materials and the easy operation; the results are determined after only once measuring with acceptable errors.
