| Abstract: | 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. |
