Excavated soil quantity estimation method by using Unmanned Aerial Vehicle

摘要

This paper describes the method of presuming the amount of the soil in the excavating work of the river by using UAV (Unmanned Aerial Vehicle). The study area is placed in the Kuzuryu-gawa River Nakafuji-Shimbo district, in Fukui city. The point cloud data and 3D models were generated aerial photographs before or after excavating work, and two time series DSM (Digital Surface Models) were calculated. The UAV was an effective tool to calculate the volume of excavated soil.
