[0002] Transmission line inspection, in addition to obtaining 3D point cloud data for analysis of clearance safety distance, tower inclination, tower displacement, and tower base terrain changes, it is also necessary to use high-definition image data to analyze hardware defects, foreign objects on towers and wires, and short circuits. Fire traces, etc., as well as broken strands of wires, etc. need to be analyzed through infrared images, and these defects are located. The existing line inspection method is to collect 3D laser point cloud data, high-definition image data and infrared image data by air flight respectively, and Independent analysis not only has low collection efficiency and high flight safety factor, but also has a large number of redundancy in defect AI analysis, which makes the actual inspection cost high and low efficiency

The invention discloses a method and device for efficient collection of multi-source data for power transmission line inspection. The device comprises: an unmanned aerial vehicle, and a line inspection multi-source data collection device mounted on the unmanned aerial vehicle through a mounting structure; The line patrol multi-source data acquisition device includes control and memory, and an infrared image and visible light image integrated sensor, lidar and position and attitude measurement unit electrically connected with the control and memory. The invention utilizes the multi-source data acquisition equipment of the drone to be attached to the patrol line to collect the data of the tower rod and the wire of the electric tower, and can obtain the infrared image and the visible light image of the tower rod and the wire of the electric tower synchronously through one flight, and The three-dimensional laser point cloud data, the three-dimensional space position and attitude data of the equipment do not need to be collected separately for flight, so at least two-thirds of the data collection time is saved, and the safety risk of flight is also reduced by two-thirds.
Description
technical field [0001] The invention relates to the technical field of power transmission line inspection, in particular to a method and device for efficient collection of multi-source data for power transmission line inspection. Background technique [0002] In the inspection of transmission lines, in addition to obtaining 3D point cloud data for analyzing the clearance safety distance, tower inclination, tower displacement, and tower base topographical changes, high-definition image data is also used to analyze hardware defects, foreign objects on towers and wires, and short-circuits. Fire traces, etc., and it is necessary to analyze the broken strands of wires through infrared images, and locate these defects. The existing line inspection method is to collect 3D laser point cloud data, high-definition image data and infrared image data by flight and collect them. Performing independent analysis not only has low collection efficiency and high flight safety factor, but also...
