3D-COFORM

Thanks to a postdoctoral grant, I joined the CNR ISTI in Pisa to participate to the ERC project 3D-COFORM dedicated to the elaboration of new low cost and user friendly tools for the 3D documentation of tangible cultural heritage.

As a partner of the project, the ETH of Zurich has developed a real tile structured light range scanner. This kind of scanners allows to greatly speed up 3D scanning, but often to the detriment of quality, clearly below what other types of technologies are able to produce. I thus developed a new method exploiting the own characteristics of this scanner so as to reconstruct a colour texture without shadow nor reflection over the 3D model, as well as to refine its geometry. This second step indeed allows, thanks to a photometry stereo approach, to recover many fine details that the scanner alone is not able to capture.

During this period, I also participated to several scanning sessions of the Tuscan cultural heritage, in support of projects for restoration or study in history of art.
