A study on rescue operation support systems using 3D reconstruction of disaster scenes with human cooperation via digital pen and dot screen

Three-dimensional computer graphics (3DCGs) of disaster scenes can be created to visualize the situation of the disaster areas. Our system is based on the Structure from Motion (SfM) technology with collected photographs or videos taken with digital camera or video camera. Moreover, it is possible to write information onto the surface of these 3DCGs through the handwriting with a digital pen and the dot screen; the 3DCGs are projected with a projector on the dot screen. The 3DCG created from images taken by victims or rescue teams is a useful tool for disaster relief. This paper presents the simulations that took place in the disaster experience facility “Sona Area Tokyo of The Tokyo Rinkai Disaster Prevention Park” and “921 Earthquake Museum of Taiwan in National Museum of Natural Science.”
