Three-dimensional digital model of the Minerva of Arezzo

The aim of this work is to show how 3D techniques can be used to integrate standard diagnostics, adding useful and powerful tools for the restorers. Our plan is to assemble a few complete 3D digital models of a bronze statue, the Minerva of Arezzo, either before or during its repair, to keep trace of every significant modification occurring in the restoration process. Variations of the statue's shape, due to the removal of plaster and to the polishing of the corroded bronze surface, are indeed foreseen. 3D measurements have been realized by means of a very high-resolution laser scanner developed at INOA; the instrument is supported by a manageable software for data handling.
