Acquisition of detailed models for virtual reality

More and more archaeological sites are being reconstructed in virtual reality. The problem remains the huge effort that has to be made to obtain realistic models. Besides on-site measurements, much time is often spent in manually rebuilding the whole site with a CAD package or a 3D-modelling tool. This limits the tractable complexity. In this paper two flexible automatic 3D surface acquisition systems are used to “virtualise” archaeological sites. The Roman site of Sagalassos (Southwest Turkey) is used as a test case to illustrate the potential of these new approaches. Besides the construction of a virtual site consisting of different level of details, some more applications to archaeology and conservation of heritage sites are presented.
