In Valcamonica/Italy, the petroglyphs, the socalled Pitoti, were chiselled into the cliffs by prehistoric cultures. These valuable artefacts form part of Europe’s cultural heritage. Their study is frequently extremely troublesome because of the difficulty of accessing the slopes on which they are found. In 3D-PITOTI, the three-dimensional nature of the petroglyphs is being investigated and documented for the first time. The project is headed by the University of Nottingham. The role of St. Pölten UAS is to address the development of intelligent technologies for data processing that manipulate the scanned 3D data based on methods of classification, clustering and retrieval so as to recognize the inherent structures in the data and make them useable. The project aims at making the rock paintings accessible not only to persons with special interests but also for the first time to a wider public in an attractive and interactive manner.
