Underwater beam structure for test, Geocean

This work is a precision test on a metal beam structure sucessively measured in the air, on the quay, then immersed. This model is done underwater with 1200 photographs. See here the 3D model showing the difference between the aerial model the this one : https://skfb.ly/6JvQz And here the same beam measured on quay : https://skfb.ly/6JvSr Test done at the request of the company Geocean https://www.entrepose.com/en/geocean/ Underwater photogrammetry carried out as part of a collaboration between Septentrion Environnement and LIS (Laboratory of Computer Science and Systems) Aix-Marseille University, UMR CNRS 7020.
