Technologie 3D et relevé d’art pariétal : une application inédite dans la grotte de Marsoulas

The third dimension always constitutes a major difficulty in the study of the Palaeolithic cave art. At the Marsoulas cave (Haute-Garonne), a 3D scan operation was undertaken in keeping with various constraints in terms of time and space which the site imposes on the research. The 3D scan emerges as a new way of improving on the initial phase of plotting prehistoric paintings, and can subsequently facilitate their final mode of restitution
