Power transmission line galloping detection method and device, computer equipment and storage medium

The invention relates to a power transmission line galloping detection method and device, computer equipment and a storage medium. The method comprises the following steps: collecting video data containing a power transmission line; performing target detection on the spacer in the video data through a YOLOv5 target detection algorithm, and obtaining a detection result; performing tracking detection on each detected spacer by using an L-K pyramid optical flow method to obtain a galloping track of each spacer; and obtaining a power transmission line galloping range threshold, determining a power transmission line galloping grade according to the galloping range threshold and the galloping trajectory, and giving an alarm. By acquiring video data, contact measurement on the power transmission line is not needed, so that the time cost and the economic cost for mounting and fixing a measuring device can be saved, and the workload of regularly maintaining equipment by researchers is reduced; the spacer can be accura
