Abstract

The idea underlying this proposal is to understand the exploitability of scanning technologies for studying and observing the shape variability of marine sessile benthic organisms with particular focus on corals. This is a preliminary study in order to compare the different systems, laser-based and photogrammetric techniques, for 3D shape reconstruction and color information. The approach to the study has been schematized by using several solutions, with the aim to investigate performance in terms of operation, process reliability, quality and metric accuracy of 3D models obtained by processing with image-based techniques. The investigation involves the use of a pool to build laboratory tests characterized by different complexity of structures (especially in terms of size and shape) in an underwater environment. Results show the difference between 3D models obtained by a 3D color laser scanner prototype (RGB-ITR) developed in ENEA ArtVisLab (Frascati) and standard commercial cameras. The difference in terms of color is highlighted.
