摘　　要：针对维氏硬度压痕测量过程中由于物理光源照射产生的图像照度不均匀现象,研究了基于数字形态学的Top-Hat算法,对图像光照均匀度进行了校正。并针对传统Top-Hat存在的问题,提出了一种改进的算法。试验证明,该算法可靠有效,能够满足维氏硬度测量的工程实际要求。Imaging at the physical light source leads to uneven illumination images in the process of the Vickers indentation measurement.Some researches based on the Top-Hat algorithm are done to get the even illumination image.An improved algorithm has been proposed because the traditional Top-Hat algorithm has some disadvantages.The experimental results show that this algorithm is reliable and effective,and can meet the needs of the actual production very well.
