The designed survey, combining both sensors, improved the knowledge of the conservation state of
the monumental compound chosen as test building. Often the two sensors are used separately,
decoupling the laser scanning data for 3D reconstruction and thermographic images to detect the
anomalies; instead, the obtained results showed how the terrestrial laser scanner could be used as a
diagnostic tool combined with other non-contact sensors, in order to study the architectural pathologies
and to evaluate the vulnerability of historical buildings. In fact, following the proposed methodology,
the systematic application of the data comparison allowed us to understand the potential of the integrated
use of the two sensors, in order to recognize any decayed features. Moreover, it was possible to disclose
hidden elements in the masonry and recognize zones characterized by different properties, probably
caused by subsequent construction interventions in both ancient and recent times, therefore with different
techniques and materials from the original ones.
