Embodiment
[0041] A visual detection method for a disk-shaped suspension porcelain insulator in this embodiment, the steps are:
[0042] 1) Establish a feature library of various defects;
[0043] 2) Determine the range of feature values in the feature library of each type of defect, and then subdivide the type of defect, and establish a more detailed defect reference database, so as to be able to judge which type of defect and which state; step 2 ) is as follows: 2-1) prepare pictures in various states of various defects; 2-2) scan the pictures prepared in step 2-1) into the industrial computer; 2-3) collect the The image is converted into a grayscale image, and the region of interest to be measured is selected on the converted grayscale image; 2-4) Blob analysis is performed on the ROI, and then the characteristic value ranges of various defects in various states are obtained.
[0044] 3) Send instructions to the mechanical system through the industrial computer to transport the por...
