From Uruk to Ur:: Automated Matching of Virtual Tablet Fragments
... As part of the Virtual Cuneiform Tablet Reconstruction Project, [6], [7] virtual reconstructions have been reported for, typically, small form factor tablet fragments collocated within individual collections [8], [9]. This paper provides an account of the computational aspects of model acquisition and join geometry for the virtual reconstruction of fragments of a different form factor, in different collections, located in different countries. ...
... In our system, a pseudo-random calibration pattern adhered to the top surface of the turntable is used for the automated calibration of the reconstructed 3D model. This system has been tested with laboratory-fabricated synthetic artefacts as well as with approximately 100 cuneiform tablet fragments from the Ur collection currently housed on study loan at the British Museum [9]. An example of the models obtained from two Ur fragments, that were known to join, is shown in figure 2 and demonstrates that the accuracy and precision of the system is sufficient to verify matching joins between fragments. ...
... Virtual cuneiform tablet reconstruction has previously been demonstrated for automatically identifying joins within a collection [9]. This join has demonstrated that there need be no geographical limitations and joins can be found between collections in different parts of the world. ...
The epic of Atrahasis is one of the most significant pieces of ancient Mesopotamian literature. The account has survived millennia on sets of clay tablets inscribed with cuneiform script; a sophisticated early writing system comprising signs formed from wedge-shaped impressions. The third tablet belonging to one of the most complete copies of the Atrahasis epic is broken. For over fifty years, one fragment, held in Geneva, was believed to join with another held in London. However, due to their 1000 km separation, the join had never been physically tested. This paper contributes a technological account of the successful virtual joining of the fragments, the first ever long-distance virtual join of its type.
... The implemented system is shown in Figure 7 together with a touchscreen version. Tools for automated joining (snap-to-fit) have also been developed and tested, together with a set of fit statistics, and have been successfully used to join multiple laboratoryfabricated fragments and also scans and photogrammetric acquisitions of real cuneiform tablet fragments (Collins et al., 2014(Collins et al., , 2016Gehlken et al., 2017). Further work is needed to integrate these tools with the automated matching tools and to further evolve the remaining tools and the environment; for example, by supporting interface personalization (Burkolter et al., 2014). ...
