Abstract
Since several years our laboratory in ENEA Frascati Research Center is involved in development of laser scanners for Cultural Heritage investigation problems. Actually the best result obtained in this field by our laboratory is a 3D Red Green Blue Laser scanner, called RGB-ITR: the main feature of this scanner, further then measuring distances (up to 20m with a sub-millimetric resolution), is the ability to capture remotely color information by three calibrated laser sources: this information is collected for each point sampled by the instrument and is not affected by external light sources' influence. Moreover the ability to acquire color and distance information at the same time and for each point decrease drastically the post-production pipeline of a complete mesh. In this work the results of a complete scan of S. Peter Martyr in Rieti are shown, highlighting the efficiency and robustness of color calibration algorithms introduced for a correct color representation.
