Remote diagnosis and control of the heritage Architecture by photorealistic digital environments and models

The paper is going to discuss a methodological workflow, 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 the architectural heritage. Specifically, from the identification of 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, 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 employment of image treatment routines on coloured point clouds with the purpose of carrying out semi-automatic operations of decay monitoring for post-diagnosis control.
