Overhead transmission lines are important transmission channels in the power system.Long-distance and complex terrain overhead transmission lines pose significant safety risks,which are limited by geographical conditions,climate and other factors,and can not detect potential problems of transmission lines comprehensively and accurately.To this end,unmanned aerial radar inspection technology for long-distance and complex terrain overhead transmission lines is proposed.Based on the principles of unmanned aerial vehicle based laser radar system and different operational scenarios,point cloud data are collected and preprocessed for fusion and classification,data fusion calculation is completed,and power professional reports are generated to achieve transmission line inspection.Practical application cases demonstrate that this technology can effectively improve the efficiency of project operations with good data quality and high accuracy and meet project requirements,which fully demonstrates the superiority of unmanned aerial laser radar technology in the application of overhead transmission lines inspection.
