Abstract

Abstract: In order to solve the difficulties of manual surveying of coastal reclamation areas,the accuracy and density of points can not meet the needs of high-precision reclamation calculation,this paper uses the UAV airborne LiDAR point cloud to calculate the reclamation amount and presents a complete technical flow which is suitable for UAV airborne LiDAR point cloud classification,high precision digital elevation model modeling and calculation of the amount of blow fill in coastal reclamation area.The results show that the UAV LiDAR technology can effectively solve the problem of high-precision calculation of the amount of blow fill in coastal reclamation projects,and has significant application advantages and broad development prospects.

Key words: unmanned aerial vehicle, LiDAR, point cloud classification, DEM, reclamation volume calculation
