| Abstract: | 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. |
