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...

Abstract

The invention discloses a machine vision-based electronic connector detection method, which belongs to the technical field of computer program design and includes image collection, image analysis and processing, and the like. The actual target image is processed by image smoothing, image segmentation, image matching, edge extraction, color recognition and other methods to obtain the complete geometric characteristics of electronic connector defects, so as to realize automatic detection. Experiments have proved that the detection results of the system are consistent with the detection results of human eyes, which not only ensures the accuracy of detection, but also greatly improves the efficiency of electronic connector detection.

Description
