Outline of Final Research Achievements

In this study, the observations of affected areas due to earthquakes and tsunamis were carried out from unmanned multi-copters (UAV or drone). The Structure-from-Motion (SfM) technique was then used to model structures in the areas from the acquired videos and still photographs. Overturned buildings due to tsunamis in the 2011 Tohoku-Oki earthquake, and the surface ruptures, collapsed tombstones, landslides, damaged bridges and buildings due to the 2016 Kumamoto earthquake were observed from a UAV and their three-dimensional (3D) models were developed. The damage situations could be captured from the developed models in detail. By adding the coordinates of ground control points from GPS data, the accuracy of the 3D models were validated.
