| Outline of Final Research Achievements |
We have developed an incremental tetrahedra carving algorithm, where the tetrahedra-carving-based surface extraction algorithm was extended to the incremental fashion by efficiently detecting ray-tetrahedra intersections and the dynamic graph cut. Then we have built an online 3D modeling system using aerial images, where the user can immediately confirm the 3D model updated by the aerial images captured by the camera mounted on a drone operated by remote control. In addition, we have developed a method for refining the 3D model estimated by the online 3D modeling system, where we estimate not only 3D surface parameters but also illumination parameters and surface albedo. These achievements have been awarded the SSII Audience prize and Academic prize at SSII2013, and the SSII Audience prize at SSII2016.
