Remote diagnosis and control of heritage architecture by photorealistic digital environments and models

The paper will discuss a methodological workflow which is focused on the role of photoscanning-based immersive environments and three-dimensional models as tools for sharing, interpreting and elaborating diagnostic data for the assessment and control of the state of conservation of architectural heritage. Specifically, from the identification of certain fields and aims, where the available tools and functionalities meet the support needs by the stakeholders, some experimental applications are developed with reference to two main aspects. The former concerns the creation of virtual tours of panoramic scenes, which are enriched by data from preliminary investigation, in order to enable the coordinated and integrated fruition of the pre-diagnosis qualification outcome. The latter relates to the use of image treatment routines on coloured point clouds in order to carry out semi-automatic operations of decay monitoring for post-diagnosis control.
