| Outline of Final Research Achievements |
We have studied methods for spatio-temporal modeling of a city from image sequences of its streets acquired periodically by a vehicular camera, having developed a number of methods each of which can be selected and used depending on the purpose and the types of available data. Meanwhile, targeting at the disaster areas of the Greate East Japan Earthquake, we have periodically run a vehicle with a camera and have created an image archive recording the recovering processes of the disaster area, the amount of which is 40 terabytes including the data we had captured before this project. Additionally, the performance of the developed methods were examined using the same data. These achievements have paved the way to be able to visualize damages right after the incident, monthly recovery process, and yearly reconstruction process seen in the disaster area as well as to quickly grasp damages of future natural disasters.
