摘　　要：近年来无人机航空摄影方式飞速发展,因其作业方式机动灵活,功能多样化,成本较低,时效性好等优势,在输电线路勘测设计中的应用越来越广。本文以江苏某500kV输电线路工程为实例,介绍采用差分PPK无人机航空摄影测量技术,在稀少控制点条件下进行解算,生成的产品经外业实测结果表明能够满足输电线路勘测相关规范的要求,同时节约了人力及成本。In recent years, the development of UAV aerial photography is rapid, because of its flexible operation mode, diversified functions, low cost, good timeliness and other advantages, the application in the power system is more and more widely.This article introduced the application of the UAV based on POS in the power system based on one 500 kV line engineering.And, verified the use of UAV based on POS system in reducing the measurement control points when selecting appropriate layout scheme, it could still meet the requirements of transmission line.So, the technology could be used in the measurement of transmission line and at the same time saving manpower cost.
