Title:
SYSTEM AND METHOD FOR MEASURING DISTANCE BETWEEN TRANSMISSION LINE AND IMAGE BY UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/170878
Kind Code:
A1
Abstract:
A system and method for measuring a distance between a transmission line and an image by an unmanned aerial vehicle. The system comprises an unmanned aerial vehicle (3), a master console (4) and a plurality of cameras (5). The cameras (5) are fixed on power poles and towers (1) and are used for acquiring two-dimensional image data of a transmission line corridor, and the unmanned aerial vehicle (3) comprises a body (31), a lidar device (32) and a rotor assembly (33), a power device (34), a flight control processor (35), a state detection device (36) and a wireless communication module (37). The lidar device (32) is used for acquiring three-dimensional point cloud data of the transmission line, and the master console (4) is used for receiving the two-dimensional image data and the three-dimensional point cloud data, and establishing a mapping relationship between the two-dimensional image data and the three-dimensional point cloud data; identifying a target object according to the two-dimensional image data, determining three-dimensional point coordinates of the target object according to the mapping relationship, and calculating the distance from the target object to the transmission line according to the three-dimensional point coordinates of the target object. The distance from a target object in the whole transmission line corridor can be monitored by means of the cameras (5), implementing all-weather and full-day monitoring of the transmission line.
