Outline of Final Research Achievements

In this research, the methods to extract building damage due to natural disasters from unmanned aerial vehicles (UAVs) are investigated. Thermal and optical images were acquired from a small manned helicopter in the daytime and nighttime just after the 2012 tornado that hit Tsukuba City. Comparing these images and field survey data, the possibility to extract building damage from aerial thermal images was suggested. Furthermore, an attempt to construct 3D digital models was carried out using aerial images take from a UAV for damaged buildings due to the 2011 Tohoku earthquake tsunami.
