This characterization also plays a key role in identifying previous restoration activities and planning new ones. Cultural heritage preservation implies therefore a detailed knowledge of the structural integrity and fracturing conditions of artefacts, monuments and historical buildings 3. The consequences may be even more serious if natural predisposing heterogeneities in the rock texture and microfractures are already present in the original materials 2.
As all rock types, stones can experience physico-chemical weathering, deterioration and damage during time 1. Throughout history, ornamental stones have been the most common materials of monumental sculpture. The proposed methodology is efficient in fracture detection and location and improves the readability of the final results also for non-expert geophysical interpreters, offering guidance to the museum for preservation and restoration of the masterpiece. local dissimilarity computation) to define a combined damage index. A data integration approach is then proposed for the joint interpretation of the geophysical results, exploiting the final ultrasonic velocity model and radar attribute analysis (i.e. Geophysical results are incorporated within the 3D model of the statue retrieved from total station measurements, ground-based and handheld laser scanning. We present the results of radar and ultrasonic prospections carried out on the statue of the young Ramses II, an absolute masterpiece of the Egyptian art preserved in the collection of the Museo Egizio of Torino (Italy). Although the two techniques are widely applied together, an integrated approach for data interpretation is still missing. Both methods proved to be efficient in the detection and location of fractures and weaknesses within the investigated artefacts. The combined acquisition of 3D ultrasonic tomography and radar scans is growing for cultural heritage diagnostics.
