NMGCORS与无人机航测系统相结合在送电线路测量中的应用和分析--以武川变至抽水蓄能电站500kV送电线路为例

摘要

This article measures all the stages of transmission lines engineering through NMGCORS combined with unmanned aerial system by aerial photography, photo control survey, industrial optimization design and final assignment level measurement.What’ s more, we can make the most of advantages which we called“three high and one low” of unmanned aerial system.In this way, we can make up the disadvantages of big workload outdoors and explore a set of models based on the combination of the two assignments.Fur-thermore, this article focuses on the data precision of NMGCORS combined with unmanned aerial system.And we can come to the conclusion that the application of NMGCORS can not only improve the measurement precision of transmission lines’ external control, unmanned aerial system and final assignment level, but also it improves the precision of section data.In addition, it is of great signifi-cance that the applications of NMGCORS speed up the project’ s progress of transmission lines measurement and further improve the production efficiency.%通过NMGCORS与无人机航测系统相结合对送电线路工程勘测设计各测量阶段进行航摄、像控、内业与优化设计和终勘定位测量，充分发挥无人机航摄系统“三高一低”的优势，弥补以往外业工作量大的缺点，探索出一套基于二者相结合的作业模式，并重点分析NMGCORS与无人机航测系统生产的数据精度，结论表明不仅NMGCORS的应用能提高送电线路外控、无人机航测和终勘定位的测量精度，提高断面数据精度，还对加快送电线路测量的工程进度，进一步提高生产效率具有重要意义。
