Infrastructure inspection by drone – circularity study of a water tower

Circularity study of a water tower by drone and aerial photogrammetry.

Results obtained from 211 aerial images taken by the company Adeole.
Post-processing by Drones Imaging.

Inspection performed as part of a study to detect surface deformations and vertical defects of a circular structure.

roundness

Realized with 3DReshaper, the calculation of successive horizontal sections over the entire height of the water tower (from the dense cloud and every 10 cm) made possible the detection of a dozen surface defects (mainly concrete bursts). The 240 profiles thus generated, also made it possible to control the verticality of the structure with respect to a vertical reference axis.

A relevant and directly applicable use case for the inspection of storage tanks (oil & gas), treatment plants, agricultural tanks, towers or dungeons for example.
