倾斜摄影测量技术在土方量算中的应用

Application of the UAV tilt photogrammetry technology in earthwork calculation

针对传统土方量算采集效率低、采集间隔大、测算精度受限等问题,主要介绍一种基于实景三维数据的土方量算方法,通过无人机倾斜摄影技术、点云分类及高程修正方法,制作高精度的DEM数据。结果表明:基于实景三维的土方量算方法具有作业效率高、量算精度高等特点,为工程成本核算、工期安排提供了有力保障。

Aiming at the problems of low collection efficiency,large collection interval,and limited measurement accuracy in traditional earthwork calculation,a method for earthwork measurement based on real 3D data is mainly introduced in this paper.It can produce high-precision DEM data through the UAV tilt photogrammetry technology,the point cloud classification and the elevation correction method.The results show that the earthwork measurement method based on real 3D has the characteristics of high operation efficiency and high measurement accuracy,which provide a strong guarantee for engineering cost accounting and construction schedule arrangement.
