Outline of Final Research Achievements

Many important ruins still remain in Mongolia. However, not many of them have been restored or protected methodically, yet. In Mongolia, our purpose is to digitize large scale ruins from the 8th century to the 18th century, which are at risk of being lost.
In this study, two methods were used to acquire geometric information efficiently.One was used via 3D scanning device, and the other was used via sequential images acquired from a drone with a camera. The method of using the 3D scanning device has very high accuracy, while it takes a good amount of time to measure.Meanwhile, the method of using the drone is less accurate than the 3D scanning device, while it takes almost no time. Therefore, it became possible to efficiently digitize large scale ruins integrating geometric information of ruins acquired using the 3D scanning device and the drone. Furthermore, the results of research have exhibited in Mongolian Karakoram museum to contribute to the good of the international community.
