In recent years, underwater photogrammetry has been introduced and even implementations of unmanned underwater vehicles (UUVs) have been used to explore the underwater environment. Johannes Lienhart tackles the challenge of implementing underwater photogrammetry for use in Swiss lakes. Possible use cases of such a setup are the inspection of underwater structures and the investigation of the sedimentation process of the lake bottom. The project addresses the challenges associated with an underwater photogrammetry setup, particularly the poor visibility in Swiss lakes compared to other studies in marine environments. The main part of the project is dedicated to building the hardware, testing its basic functionality and interfacing it with the UUV Proteus from Tethys Robotics.
