3D MODELLING OF ARCHITECTURAL BLOCKS AND ANTIQUE SCULPTURES FOR THE CONSERVATION AND THE PROMOTION OF ARCHAEOLOGICAL HERITAGE – EXPERIMENTS IN ALSACE

Abstract. This paper presents the results of several studies led on the 3D modelling of blocks by photogrammetry. These blocks are constitutive elements of vestiges of buildings and tombs from the Roman period. A first series of blocks are a part of a mausoleum, a second are parts of tombs, and a last series are part of an antique theatre. The 3D modelling has been undertaken to get the maximum of 3D knowledge elements for the virtual reconstruction, in particular of the mausoleum. As the theatre is still not perfectly identified, the blocks served as 3D geometrical base for a more advanced archaeological study. The 3D modelling of these blocks allowed to sum-up the processing chain used for the first types of blocks and to adapt it to particular conditions of data acquisition.
