Abstract

Three-dimensional computer graphics (3DCGs) of disaster scenes can be a visualization method of the situation of disaster areas. The 3DCG created from photographs taken by victims or rescue teams is a useful tool for disaster relief. We propose a system based on the Structure from Motion (SfM) technology to reconstruct the 3D models of disaster areas. And it's also based on the attached GPS data within collected photographs taken by smartphones at the disaster sites to localize the reconstructed 3D models on the global map. We describe how it registers 3DCGs to a global map and how it estimates the positions and orientations of 3DCGs here. Moreover, users can edit the reconstructed 3D models with a digital pen and a dot screen in this system; use a projector to project 3DCGs on the dot screen. This paper shows the use of GPS information and presents the simulations that took place in the disaster experience facility Sona Area Tokyo of The Tokyo Rinkai Disaster Prevention Park" and the 921 Earthquake Museum of Taiwan in the National Museum of Natural Science."
