Grotta Romanelli portable art: GRM1023 optical scan model

Résumé

On the occasion of the review of the portable art of Grotta Romanelli, a decorated stone with a feline figure, GRM1023, was object of an interdisciplinary study. The object was threedimensionally recorded using both photogrammetry and optical scanning. High detail model of GRM1023 and its engravings was made using the Artec Space Spider structured light optical scanner. The scanner reaches a high level of accuracy (0.05mm) and, at the same time, allows scanning of object up to 40 cm in length, without posing any danger to the integrity of the scanned specimen. GRM1023 was carefully placed cloth with an opaque black colour to avoid colour contrasts during scanning. Three scans were made at separate times rotating the rock fragment, capturing the entire find collecting information about its texture and morphology. The scan session duration was of 10 minutes and data were saved within the software Artec Studio 16 Professional. Through the same software the scans were aligned to create the original morphology of the object in all its parts. After cleaning the ordinary disturbing elements, the mesh was created, to which the texture was subsequently applied. The final models are constituted by 1.600.000 facets and have been exported in the .OBJ file type.
