Research on the Application of UAV Oblique Photogrammetry Technology in Earthwork Calculation
In view of the problems of low collection efficiency and slow indoor processing in the traditional survey method,the Pegasus UAV oblique photogrammetry technology is used for earthwork measurement and calculation in this paper. First,this paper introduces the Pegasus UAV oblique photogrammetry equipment;secondly,taking the earthwork calculation of a survey area as an example,it u-ses the Pegasus UAV Butler and ContextCapture software to obtain the real 3D model and 3D point cloud data,and the grid method is used to calculate the earthwork;finally,the RTK is used to measure the on-site earthwork and compare with the earthwork calculation results obtained by the UAV oblique photogrammetry. The experimental results verify the superiority and feasibility of UAV oblique photogrammetry technology in earthwork calculation.
