This work is a precision test on a metal beam structure sucessively measured in the air, on the quay, then immersed.
This 3D model shows the difference between the beam measured in the air and then in the water. The color scale shows the differences between the two models (maximum red positive and blue, negative 1 cm). We can see that the scalebar are moved during the immersion phase of the structure.

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.
