Embodiment Construction
[0053] The present invention will be further described below in conjunction with specific examples.
[0054] Such as figure 1 As shown, the specific conditions of the machine vision-based transmission line conductor defect detection method provided in this embodiment are as follows:
[0055] Step 1: The UAV conducts fixed line inspections on the transmission line, and takes on-site images of high-voltage towers near the towers, such as figure 2 shown, and transmitted to the remote server over a long distance through the 4G network.
[0056] Step 2: Divide the on-site images collected by the drone into the training data set and the test data set in a ratio of 7:3, use Labelme software to mark the edges of the wires in the training data set, and obtain the label file of the corresponding image in json format , the annotation file includes the rectangular coordinate data of the wire target in the image, the mask point set data and category information, and the pictures and lab...
