[0044] (1) By cooperating with the power department, the aerial image of the transmission line is obtained as the original data set DataSet 1 , preprocess the acquired aerial images; use the Vision Transfomer algorithm to build a self-recognition classifier for a single image, identify each image in the data set, and use the classifier to classify the recognized images; There are two categories including insulator parts and those that do not include insulator parts, and those that include insulator parts are marked as Class A, otherwise, they are classified as Class B images.
[0045] (i) Input an image i, and note that the probability of being recognized as class A is P iA , the probability of being identified as class B is P iB , the P iB Results in more than 90% of the images are put into the collection DataSet 2 , the sample dataset becomes a DataSet 1 -DataSet 2 , denoted as DataSet 3 .
[0046] (ii)P iB Although the result is above 90%, it may still contain image...
