摘要
输电线路终勘定位包括塔位中心放样及测量、塔基地形图测绘等工作,现阶段基本采用架站RTK或省CORS RTK方法进行测绘。线路途经通信网络信号差、交通不便、地形起伏大、植被分布不均的复杂山区时,常受架设参考站及网络信号不均匀分布的影响,给终勘定位工作带来诸多不便,增加劳动强度,降低工作效率。为解决以上问题,本文研究采用网络CORS RTK与无人机载LiDAR相结合的方法进行终勘定位工作。实践表明,所采用方法可显著提高工作效率,降低劳动强度,减少天气的影响,保证终勘定位精度,对终勘定位工作具有一定的实用价值和参考意义。
Transmission line final location survey includes tower center layout and surveying and tower site topographic mapping.At present,RTK or CORS-RTK techniques are the commonly used method for surveying.However,in complicated mountainous areas with poor communication network signals,inconvenient transportation,significant terrain fluctuations,and uneven distribution of vegetation,the final location survey work is often hindered by set up reference stations and uneven distribution of network signals,which resulting in inconvenience,increased labor intensity,and decreased efficiency.To address these issues,this study proposes a method combining network CORS-RTK and UAV-borne LiDAR for the final location survey work.The practices show that this method can significantly improve work efficiency and reducing labor intensity,minimize the impact of weather conditions and ensure the accuracy of final location survey,so it can provide practical value and reference significance for the final location survey work.
