Laser and photogrammetry data merge: 3D modeling of a tourist residence by coupling aerial and terrestrial points cloud
Laser and photogrammetry data merge: Roof 3D modeling by aerial photogrammetry and merging with a points cloud built by laser scanner. Results obtained from 314 RGB images taken by Altitude Drone Diagnostic. Post-processing by Drones Imaging.
Aerial and terrestrial points clouds merged
Service carried out as part of the rehabilitation of ski residences in Val d’Isère.
Coupling laser and photogrammetric data makes it possible, in this use case, to fill in all the mask areas inaccessible with laser scanning. Thus, after merging the 2 models BUILT respectively by aerial photogrammetry (drone for the roof part) and terrestrial laser (for the four facades), the first residence in Val d’Isère was fully modeled and delivered for subsequent use in the office of study with Autocad.
