| Outline of Final Research Achievements |
In this research, some methods for combining several 3D scan data from various 3D scanning systems and optimized scanning in order to obtain high quality 3D scan data of large-scale environments and structures. For combining several 3D scan data, efficient automatic registration methods for 3D scan data acquired from terrestrial laser scanner, mobile laser scanner, handy scanner, and structure from motion are developed. For optimized scanning, methods to estimate best laser-scanner positions which allow us to acquire high quality point clouds with a smaller number of scanning, considering scanning importance of the objects and laser-scanning properties, are developed.
