Digitisation of museum objects

25 Aug

The digitisation of some museum objects from the Regolini-Galassi tomb has started on August 24.  The photographic department of the Vatican Museums has made extensive and specific photography that will allow us to create 3D models, that will be used in the exhibitions in Amsterdam and Leiden (Netherlands) from October 13 2011 onwards.

The objects were put on a turntable and in an object tent that allows to have a very even lighting on the objects.

As we want the 3D objects to look like new (as we reconstruct the tomb just after closure), most of the work goes into digital restoration of the objects, or by hand modeling based upon the existing or new photography, or by editing the digitised models (made by dense stereomatching of photographs).  The resulting 3D models will be optimised and visualised in real-time with special techniques to obtain a high degree of realism without an excessive amount of data.

Several objects were documented through the Object VR technique, by photographing the object while it is rotated on a turntable.  In the image below, the 6-headed lebes is recorded in 36 photographs with consecutive rotations of 10 degrees.  These images do not only provide a very detailed documentation of the object but allow also for future use on the internet or in multimedia systems in exhibitions.

The Etruscanning team is very greatful to the team of the Vatican museums for the excellent cooperation in this three day digitisation effort.
