A proposal for a new standard quantification of damages of cultural heritages, based on 3D scanning

In the field of Architectural Restoration, conservation is a fundamental matter to ensure the durability of a built heritage, with historical and artistic values. The process of Conservation consists in the planning of series of interventions, preceded by an accurate phase of investigation about all the main aspects characterizing the artefact. Therefore, it is necessary to perform a preliminary assessment of the general conditions and, eventually, to appraise the presence of pathologies, according to the recommendations contained in the International and European Standards. However, the limit of the major existing legislations is the lack of quantitative criteria to identify and classify alterations. This work aims to make a proposal for an integration of the existing standards, with the identification of meaningful parameters in correspondence of damages. The example application of the study is conducted on Palazzo Palmieri (Monopoli – Italy), through the analysis of photogrammetric 3D models.
