ドローンによる地形情報の取得と紙積層型プリンタによる3D形状の出力

抄録

In recent years, the development of unmanned aerial vehicles (UAV) and Structure from Motion (SfM) technologies for acquiring data, such as topography data, has increased the demand for full-color three-dimensional (3D) printing. Therefore, we created a 3D model of the terrain using paper lamination and a full-color 3D printer using satellite data from the Geospatial Information Authority of Japan (GSI) and data acquired by UAVs. Furthermore, we compared FDM printing and paper lamination printing. As a result, we observed that the paper 3D model was more suitable for terrain and building structures. In addition, we showed that 3D mapping of thermal images is possible for 3D modeling using thermal images captured by an infrared camera attached to a UAV. In summary, the rapid technological development of UAVs in recent years, including improvements in flight ability, camera capability, and satellite positioning (GNSS) technology, coupled with photogrammetry and SfM technologies that enable faithful 3D modeling of data acquired by UAVs, demonstrated the technological significance of full-color 3D modeling using paper lamination.
