3D Visualization and Virtual Reality for Cultural Heritage Diagnostic

This work takes place inside SIDART (Integrated System for Cultural Heritage Diagnostic) project, whose objective is to develop hardware and software package for cultural heritage diagnostic. The project involves some partner such as ENEA Group of Frascati, CNR-INOA and CETMA that is a private research center located in the southeast of Italy and also leader of the project. The aim is to develop an integrated system to acquire, integrate, process and distribute information produced by different survey instruments (laser scanner, multi-spectral camera, calibrated metric photogrammetric camera, thermography) used in cultural heritage diagnostic. This would be a new completed tool useful to restoration in architectural and cultural study application. The Laboratory of Survey, Digital Mapping, GIS of Politecnico di Milano has cooperated with CETMA to create the software able to display and to model laser scanner points clouds. The analysed clouds come from a new prototype of laser scanner product from CETMA with Enea (Frascati Group) competence [1]. This instrument has a very good accuracy (at test phase) and guarantee 10-1 space resolution. All test and other survey measures, such as multi-spectral and thermographic survey are conducted by CETMA with Politecnico permanent collaboration.
