Abstract

Digital Close-Range Photogrammetry allows to acquire high-fidelity models useful to document Cultural Heritage with a high level of detail. This technique also has an analytical potential able to gain new knowledge about works of art and their state of preservation. This project carries out a diagnostic survey using 3D Multiband modeling, High Resolution Digital X-Radiography and Pulsed Thermography to document and evaluate from a conservative point of view the polymaterial exemplars of the Garnier Valletti pomological collection. The analytical integration of Imaging techniques and 3D modeling provides information from the superficial, sub-superficial and innermost layers of the object, respectively, capturing both accurate morphometric, spectral and density data. The paper presents the results obtained on the particular case study of polymaterial and multilayer artifacts for which Pulsed Thermography has proven to be a highly predictive technique from a conservative point of view.
