Abstract
Currently,PV power stations are mostly built in areas with high altitudes,large height differences,and abundant vegetation.Conventional real-time kinematic(RTK)measurement methods have low efficiency,and unmanned aerial vehicle(UAV)oblique photogrammetry methods cannot accurately obtain the ground elevation of abundant vegetation areas.Based on this,this paper proposes a UAV LiDAR measurement method for large-scale topographic map measurement in PV power generation projects.Firstly,the technical process of UAV LiDAR measurement method is introduced from two aspects:field collection and internal data processing.Then,based on the data of application example of PV power generation projects,the application effect of this measurement method is analyzed in detail.The research results show that the vegetation penetration of the UAV LiDAR measurement method is strong,and it can quickly obtain high-precision 3D coordinates of ground points below the vegetation,the operation is simple,and there is no need to deploy a large number of image control points.The efficiency of field collection is high.The point cloud elevation accuracy of this measurement method is superior to the plane position accuracy,and it can produce high-accuracy DEM results.Contour lines can be directly extracted for topographic map drawing,and the speed of internal data processing is fast.The UAV LiDAR measurement method can better meet the time node and accuracy requirements of PV power generation project construction in mountainous and abundant vegetation areas,and can be well applied to large-scale topographic map measurement operations of PV power generation projects with large elevation differences in mountainous areas.关键词
