Abstract
The 3D reconstruction of underwater scenes is almost a requirement for a number of applications that need to gather 3D data from fauna, flora or submerged structures. In the Cultural Heritage field, 3D models of finds and archaeological sites are widely used, either for scientific research or for dissemination to the public. 3D imaging techniques based on multi-view capture are a valid and effective tool in underwater applications, because they require to capture the scene by different viewpoints using just one still or movie camera, installed on robots or handled by a scuba diver. In this paper we test a technique for 3D reconstructions from images captured by multiple views in a case study of submerged structures in the underwater archaeological site of Baia (Italy). This case study is particularly critical due to the high level of turbidity, the heavy presence of marine flora and the changing of lighting conditions, common in shallow water. All these disturbances cause a decrease of the contrast and an alteration of the colours in the acquired images. The 3D model of a portion of the site has been reconstructed in a virtual environment, both for studying and dissemination fruition purposes. In particular, a 3D application has been developed in order to allow the exploration of the site, the measurement of the architectonical elements and the simulation of the movements of a robot that performs specific operations of restoration and preservation.
