A DIGITAL DIAGNOSIS FOR THE « AUTUMN » STATUE (MARSEILLE, FRANCE) : PHOTOGRAMMETRY, DIGITAL CARTOGRAPHY AND CONSTRUCTION OF A THESAURUS

The evolution of the digital technologies allowed since the early 1990s, to multiply the photogrammetric acquisitions, the digital and mechanical diagnosis and the 3D diagnosis of the sculptural heritage, generating a better knowledge of these objects. The multiplication of these tools therefore allowed to establish multidisciplinary methodologies, generally leading towards less invasive restorations protocol. Here, the diagnosis of a case study is first accomplished, starting with a photogrammetric acquisition, then tested in the two and three dimension annotation platform named aïoli, in order to determine the current possibilities for an innovative use of these tools, benefiting at the diagnosis of the sculptural heritage. On the order hand, along with the multiplication of the multidisciplinary methodologies, a very contemporary problematic arises: the need to improve the communication and discussion between different professionals. The goal was here to offer innovative methods to give all professionals the same vocabulary, a shared knowledge, therefore allowing a better diagnosis of these pieces of art.
