Research on Optimal Design of Transmission Line Based on Airborne LiDAR Technology
-
Abstract
In some areas with dense vegetation and complicated terrain, both DEM and DSM have low result accuracy when acquired by traditional aerial photogrammetry technique, which leads to strong field survey burden in the transmission line. In this paper, we analyzed the strengths of Airborne LiDAR Technology and took optimal design of Ultra-high voltage transmission line in Northwestern Yunnan as an example to illustrate the path optimization applications and their economic efficiency of Airborne LiDAR Technology, such as precisely extract plane and profile mapping, optimize crisscross spanning design and effectively estimate demolition and crop compensation. Thus, we demonstrate the feasibility of Airborne LiDAR Technology when it is applied to optimal design of Ultra-high voltage transmission line, which can efficiently improve the design quality of the transmission line and release construction budget.
