Abstract
We developed a 3D system which estimates the damages of disaster and quantity of house debris by fusing multi fixed camera images. It is very important to estimate the quantity of debris for grasping the damages of disaster and for promoting the restoration activities. This 3D system estimates the damages of disaster by superimposing the feature points, extracted from multi camera images taken before and after the earthquake disaster, on the 3D-model. Those structure parts in the 3D model projected with many feature points are judged as damaged parts and the volume will be calculated. In our model experiments, the calculated volume of the damaged parts was reasonable when the dimension of the house model was considered.
