The artefact was selected to be 3D digitised within the framework of the European Commission funded 3D-ICONS project by the Athena RC Xanthi's Division. It was captured in 3D using the Structure-From-Motion (SFM)
and Dense Multi-View 3D Reconstruction (DMVR) methods. Automated photoshooting sessions were performed during the winter of 2014 in Avdira Museum, Xanthi.The photoshooting sessions were implemented using camera tripods and a
computer controlled high rotation-accuracy turntable. A pair of Samsung NX1000 20MP compact DSLR cameras with 20-50mm lenses were used. The data collection phase was automated based on custom software that controled the turntable
and the cameras triggering. Agisoft PhotoScan (ver. 1.1) has been used for the production of artefact's 3D digital replica. Furthermore, the calibration of the cameras was performed by the software itself.
The processing of the image sequences was performed on two computer systems (CPU IntelCoreI74820K 3.7Ghz, 64GB RAM, Radeon R9 290X,Microsoft Windows 7 64-bit).
Additionally, photogrammetric target positioning around the object and empirical measurements between strong (in terms of visibility) feature points on the surface of the artefact were performed and used to scale the 3D model.
