Ad Hoc 3D solutions

UAV

Photogrammetry has always been one of the techniques used by ad hoc 3d solutions. In 2011 our team started using drones to describe and integrate terrestrial models with aerial images. Today drone’s photogrammetry is fully integrated with all the Ad Hoc 3D processing methods.

We are authorized to use drones (Ref. Enac 19169) with certified pilots, even for critical areas. Using specific tools and software developed by us we are able to plan and control 3D flights. We carry out in 3D also the predictive analysis of the risk so as to pre-define the overflowing areas, the security zones, the areas of respect, the positions that the security flight attendants must occupy and the respect of the regulations in force.

The acquired video and images are used to generate or integrate 3D models, generate true orthophotos and perform visual inspections.

Post earthquake surveys

3D surveys after the seismic event in central Italy for the stability study of some slopes along the road network. The surveys were carried out with GPS technique, laser scanner and with drone

 Post earthquake surveys

Slope survey

Slope GPS, laser scanner and drone survey for stability studies

Slope survey

Punta Mesco

Environmental survey carried out with laser scanner and drone for coastal control. The 3D model and true orthophotos of the whole site have been generated. The 3D model has been classified and segmented for the generation of the DTM and the management of the vegetated blanket. Surveys carried out within the Maregot project

San Michele Mondovì

3D survey of the San Michele Mondovì quarry

Rascard

3D model of a 'rascard', a wooden house, by lascanner and UAV photos, Maison Gargantua, Gressan

Rascard

Rhémes-Notre-Dame

3D laser scanner and UAV survey of a river area for hydraulic studies; CAD map drawing, identification fo the vegetation, DEM/DTM generation and extraction of hydraulic sections.

Rhémes-Notre-Dame

Pont d'Ael

Laser scanner and photogrammetric surveys of the whole complex of Pondel aqueduct. Study of the slopes, of the channel path in the vicinity of the bridge, generation of orthophotos of the facades of the bridge, of the canal and of the intrados of the arch structure. Surveys made by aerial drone photogrammetry. The data produced were used for mapping the state of degradation (ICOMOS glossary) and all the restoration interventions

Pont d'Ael

Mex Castle

Integrated 3D laser scanner and photogrammetric UAV survey of the Castle of Mex VD, Village; survey of the interior and exterior parts of the main buildings. As Built documentation and production of CAD drawings (plants, elevations and sections) and of orthophotos of the facades for the planning of restoration interventions.

Mex Castle

Aosta Roman Theatre

3D laser scanner, photogrammetric and UAV survey of the Roman Theatre of Aosta. It was the first time that an archaeological site in the Aosta valley was surveyed by mean of an UAV. 200 orthophotos of all the walls, a nadir orthophoto of the site and a cylindrical orthophoto of the Cavea were produced. The analysis of the wall stratigraphy was conducted, single context recording was produced; the matrix 3D was dynamically produced by an own developed tool. For restoration purposes, a census of the Functional Elements and of the Material Component, the mapping of Conservation Status based on a ICOMOS glossary, beside the plan of intervention were produced. http://youtu.be/vEPLJyftuqM (HD) http://youtu.be/KskrUmVOoGs (no audio - low resolution - smartphone compatible)

Fenille

3D laser scanner and UAV survey of Fenille rock slope. The geotechnical analysis was performed and unstable areas were identified by using Ad Hoc semi-automated tools. The roughness of the surface was computed, the vegetation on the area was identified, and the position, kind, height and mean radius of the main trees were extracted. The 3D statistical rock falling analysis was performed. The active and passive safety interventions were designed.
