| description | In order to overcome the defect of low safety distance measurement precision of a power transmission line, the invention provides a power transmission line safety distance measuring method, which comprises the following steps: performing image acquisition on a power transmission line by adopting a calibrated binocular stereo camera; inputting the acquired power transmission line image into a YOLOv2 neural network model for power transmission line region extraction to obtain a region image; carrying out straight line segment detection on the regional image, and carrying out electric line sag fitting on the regional image to obtain target image features; carrying out feature matching on the target image features by adopting a stereo matching algorithm, so that the same targets in the image are matched to obtain a disparity map and a depth map; inputting the disparity map and the depth map into a weighted least square filter to filter out irrelevant parameters; and performing geometric calculation according to t |
