DATASETS - Integration of Non-Destructive Acoustic Imaging investigation with Photogrammetric and Morphological Analysis to Study the "Graecia Vetus" in the Chigi Palace of Ariccia

Datasets of an integrated investigation on the monochrome painting "Graecia Vetus" located in the Ariosto Room in the historical Chigi Palace of Ariccia. Three datasets including: - Dense Cloud from the surface morphological investigation of the surface by Photogrammetric Survey: 1. Zip file containing the "*.obj", "*.mtl", "*.jpg" files to open the Model. - Four matrices from structural damage investigation of the painting by Frequency Resolved Acoustic Imaging: 1. Integrated Acoustic Image (IAI) in the wideband (500 - 12,000) Hz; 2. Frequency Resolved Acoustic Image (FRAI) in the narrow frequency band 1/3 octave band centred at 1000 Hz; 3. Frequency Resolved Acoustic Image (FRAI) in the narrow frequency band 1/3 octave band centred at 6300 Hz; 4. Frequency Resolved Acoustic Image (FRAI) in the narrow frequency band 1/3 octave band centred at 10,000 Hz. - One profile and one matrix from structural damage investigation of the wall by Sonic Tests with Impact Hammer: 1. Relative variation of pulse velocity along the horizontal axis; 2. Tomographic map of the relative variation of pulse velocity inside the wall
