Image processing from laser scanners for remote diagnostic and virtual fruition of cultural heritage

Two types of high resolution laser scanners have been developed for remote applications with imaging capabilities for optical or spectroscopic characterization of CH surfaces: a three-chromatic imaging topologic radar (RGB-ITR) and hyperspectral LIF-scanning, collecting at each investigated point the entire fluorescence spectra relevant to the utilized UV laser excitation. Their combined use produces multi-layered images with enhanced information content, which is especially valuable in CH characterization of surface materials.
