Embodiment Construction

[0029] When counting copper cores, first we obtain the approximate area of ​​the copper core bundle through the profile of the copper core bundle section, and take this area as the area of ​​interest. Then, the copper core bundle is segmented by the fixed threshold method, and the segmented area is stretched, so that the distance between the copper cores is enlarged to prepare for the next segmentation. Segment the stretched image with the watershed segmentation algorithm (such as figure 2 shown). The watershed segmentation method is a mathematical morphology segmentation method based on topology theory. Its basic idea is to regard the image as a "topographic map", in which the pixel values ​​​​in areas with relatively strong brightness are larger, and the pixel values ​​​​in darker areas are larger. The image is segmented by finding the "catchment basin" and "watershed boundary". The watershed algorithm is often used to deal with such problems that the target objects in th...
