Exploration of the Technology of Constructing the DEM for Road Survey by UAV LiDAR
The current growth trend of road construction and the current low efficiency of road survey methods have caused a serious separation,and their contradiction is deepening,which limits the current rate of social and economic development.How to improve road survey methods to make their efficiency keep up with the constantly increasing speed of road construction is an important issue faced by current road survey.This article selects a certain area in Guizhou as the survey area,collects UAV LiDAR point cloud data,conducts a series of research and experi-ments of point cloud data filtering and data interpolation in the process of constructing the DEM,as well as the ap-plication of the DEM,and obtains the data of road sections by constructing a three-dimensional DEM in road sur-vey,so as to improve the survey accuracy and efficiency in road survey.
