Experiences in Image-Based 3D Reconstruction of Underwater Environments

The 3D reconstruction of underwater environments have demonstrated its importance in many situations, especially in environments potentially harmful to human beings. Its is being used to reconstruct shipwrecks, coral reefs and expedition planning, documentation and study, as well as to make easier maintenance in structures lying in deep water. In this paper, a set of techniques previously tested is described and has its relevance explained in the matter of underwater 3D reconstruction. The results confirm the efficiency of the chosen techniques and it can be concluded that this framework can be applied to similar case studies without loss of generality.
