Our ultimate goal was to include 3D graphics among the tools which can help restorers select the proper restoration procedures for the task at hand and objectively assess restoration results. For this, the David restoration was an ideal test bed to demonstrate the usefulness of digital 3D models and visualization tools in a restoration project. The scientific analysis program began in Florence, Italy, in 2002, under the direction of Mauro Matteini and Franca Falletti. Because a complex set of scientific investigations

To faithfully reconstruct the monument, all of the statues and elements of the mausoleum have been acquired in digital 3D format; then, with advanced computer graphics techniques, some of the accredited reconstructing hypothesis have been assembled and evaluated.

These allow to build accurate digital models of real 3D objects in a cost-and time-effective manner. The talk will present the capabilities of this technology focusing mainly on some issues which are preventing its wider use, such as the considerable user intervention required, the usually incomplete sampling of the artifact surface and the complexity of the models produced. Another emerging issue is how to ...

In particular, our tools support: range maps alignment, range maps merge, mesh editing and mesh simplification. The software suite has been implemented by scratch and encompasses both up-to-date solutions (alignment, editing) and some original methods (merging, simplification, and, in part, alignment). The architecture of the software suite is described and an evaluation of its ...

This is the case of Antonello da Messina’s painting “Ecce Homo”: its delicate state of conservation, with the need for constant monitoring, required a broad and in-depth diagnostic campaign to support the restorers. The project was carried out entirely in situ using non-invasive cutting-edge techniques and proposes a multimodal and data-centric approach, integrating 3D and 2D methodologies. The surface irregularities and the support were analysed with a structured-light 3D scanner and X-ray tomography. The painting materials were investigated with X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI). Primarily, the data were jointly used for a scientific scope and provided new knowledge of the painting in terms of materials and painting techniques. In addition, two web-based interactive platf...

A laser triangulation 3D scanner is used to acquire the wound geometry with high precision and to capture an RGB image aligned to the geometry. DERMA provides a single and uniform interface to: manage patient data, 3D scanning of the lesion region, and to perform different kinds of measurements and comparisons: geometric (on the 3D model) and colorimetric (on the image). All acquired data (3D geometries and images) as well as the measures calculated are stored in a database for monitoring the evolution of the skin lesion over time. The tool, developed in collaboration with dermatologists, is now under field evaluation in two dermatological clinics monitoring the evolution of wounds due to different types of skin diseases.
