Bridge inspection carried out by aerial photogrammetry.
Bridge inspection and 3D modeling of upstream/downstream faces. Results obtained from 520 aerial images taken by AirCity Diagnostic. Post-processing service by Drones Imaging.
Structure inspection by drone - 3D modeling and orthophotos of downstream & upstream faces
Very high resolution orthophotos of the upstream and downstream faces of the bridge generated for a subsequent walls inspection in the design office (by photo interpretation). In this use case, digital surface model associated with the upstream and downstream faces makes it possible to immediately isolate any severe pathologies such as “bursts” or “structural deformations”.
