Abstract

Abstract: As the main carrier of long-distance transmission of power resources, fine inspection of the operation status of transmission lines is an important means of power grid operation management and risk assessment. However, there are technical difficulties in the current inspection of transmission lines, such as low automation and low efficiency. The paper combines the high-precision spatial position information of LiDAR carried by unmanned aerial vehicles and the powerful 3D spatial analysis function of GIS. Through the research of point cloud data processing and GIS system development, such as fine segmentation of point cloud data and structured modeling of individual geographic entities, a refined 3D model of transmission line body elements based on airborne laser point cloud is constructed. An intelligent detection system for transmission line safety hazards based on GIS system is developed, forming the application of LiDAR+GIS transmission line safety inspection technology. The engineering application and effectiveness evaluation results show that LiDAR+GIS technology can achieve rapid detection of safety hazards in transmission lines, with advantages such as fine inspection and high efficiency. Research provides a more realistic spatial data foundation and technical solutions for the digital construction and upgrading of power grids, disaster reduction and prevention applications.
