摘　　要：随着经济社会的发展,特别是“新基建”国家战略的提出,特高压输电工程将加大建设力度。而在输电线路进行设计和架设的过程中,导线弧垂是衡量输电线路所承受的应力的一种表现,也是反映施工质量和线路投运后安全稳定运行的重要参数。随着无人机技术的发展,无人机测量已广泛应用于国家重大工程建设和验收等方面,通过对传统弧垂测量模型的研究和RTK无人机摄影测量的技术分析,提出一种基于RTK无人机摄影测量导线弧垂的方法,可在保证测量精度的前提下,提高导线弧垂观测效率。With the development of economy and society,especially the national strategy of“new infrastructure”,the construction of UHV(unmanned aerial vehicle)transmission project will be strengthened.In the process of transmission line design and erection,the wire sag is a kind of performance to measure the stress of transmission line,and it is also an important parameter reflecting construction quality and safe and stable operation of transmission line after putting into operation.With the development of UAV technology,UAV measurement has been widely used in the construction of national major projects.Based on the research of traditional sag measurement model and the technical analysis of RTK(real-time kinematic)UAV photogrammetry,it puts forward a method of measuring wire sag basedon RTK UAV photogrammetry,which can improve the observation efficiency of wiresag on the premise of ensuring the observation accuracy.
