Xie Jiabi · Water Resources and Power · 2011
Taking the foundation pit of Tanghai Happiness Community for an example,processing and methodology of the excavation and embankment volume calculation in complicated engineering with laser scanner is introduced in this paper.Automatic filtering algorithm that eliminates the non-ground points from the obtained massive laser point cloud,digital elevation models(DEM) generated by moving least squares(MLS) fitting as well as method of calculating excavation and embankment volume with arbitrary boundary are put forward.LIDARVIEW software for excavation and embankment volume calculation based on laser point clouds is developed through interactive data language(IDL) programming.The excavation and embankment volumes for the complicated foundation pit project in Tanghai Happiness community are calculated under different design elevations.The results show that this method is simple,fast and has high precision.
