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.
