Application Research of New Remote Sensing Technology in Tree Obstruction Detection of Power Patrol Line

The inspection of transmission line corridor is an important part of power inspection and operation and maintenance, and relying on manual on-site investigation can no longer meet the development needs of modern power grid. This paper mainly studied the airborne LiDAR point cloud technology, drone tilt photography technology in the practice of distance diagnosis, in the analysis of two kinds of new remote sensing technology in the power patrol, and the working principle and process of tree inspection operation, combined with the Hunan transmission maintenance company ± 800 kV Fufeng line, ± 800 kV Jin Su line remote sensing inspection project practical application research. The experimental results show that the application of two remote sensing technologies in the inspection of transmission line trees is effective, and the accuracy of airborne LiDAR point cloud technology is better than that of UAV tilt photography.
