Data acquisition
Most of the scenes are obtained through the integration of different point clouds, acquired with different sensors (cameras, scanners) and platforms (UAVs, etc.).
The employed terrestrial laser scanners include a FARO Focus 3D X 130 and 120 and a Riegl VZ-400. The photogrammetric surveys of the Sacro Monte of Varallo were performed with a Nikon D800E, a UAV platform equipped with a SONY Ilce 5100L and a DJI Phantom 4 Pro with its integrated camera. For Bologna and Trento a Nikon D3100 and D3X were employed, respectively.
