Abstract

In this paper, two different underwater scanning technologies are described, in order to evaluate the 3D shape and colour reconstruction of submerged objects. In particular, a new laser scanner prototype (RGB-ITR) developed in ENEA Centre of Frascati (Roma) is compared with photogrammetric technique. The colour information is an important aspect considered in this work. The laboratory tests are characterized by different structure complexity of the submerged objects. Results provides the difference between 3D models obtained by a 3D colour laser scanner prototype and a low cost cameras in order to highlight the advantages and disadvantages.
