基于无人机机载激光雷达在水土保持弃渣场中的应用研究OA

The residue pits is of utmost importance in soil and water conservation design.However,traditional methods are inefficient,non-intuitive,and require a large amount of human,material,and financial resources.With the development of unmanned aerial vehicle(UAV)and lidar technology,a new direction has been provided for the site selection design and dynamic monitoring of residue pits.In this paper,digital three-dimensional terrain models and digital three-dimensional scene models are produced from airborne lidar data.A single map for soil and water conservation residue pits from site selection design to dynamic monitoring is constructed.Then,the information of the residue pits is extracted,and comprehensive dynamic monitoring is carried out on whether the site selection design of the residue pits is compliant and legal,as well as on the disturbed area,soil and water conservation measures,and the amount of spoil of the residue pits.
