| description | The purpose of this study is to develop the system that the topography of sandy beach can be observed using UAV(Unmanned Aerial Vehicle), as the one of the method for considering the countermeasures aginst the coastal erosion probrem in Uradome Beach, Tottori. In this paper, the coastal topographic change in the Uradome beach was analyzed from the three-dimensional model using SfM (Structure from Motion) associated with the aerial image obtained by the UAV, and the accuracy of the analyzed result was discussed. The UAV used in this study was four wings flight vehicle, and the areal photos were taken per two seconds with a height of T.P. 80 meters. The photos of approximately 200 sheets were analyzed by using SfM and GIS software. The observation using UAV along the coastline worked out in 20 minutes about 2 kilometers. The accuracy of the observation with RMSE was verified from a result of the comparison between the RTK-GPS and the UAV survey, the RMSE was about 0.05m. |
