Currently, there is extensive research focused on automatic strategies for the segmentation and classification of 3D point clouds, which can accelerate the study of a landmark and integrate it with heterogeneous data and attributes, useful to facilitate the digital management of architectural heritage data. In this work, an automated image-based survey has been exploited a Region- Based Convolutional Neural Network. The training phase has been executed providing examples of images with the anomalies to be detected. At the same time, a laser scanning process was conducted to obtain a point cloud, which acts as a reference for the BIM process. In a final step, a process of projecting information from the images onto the BIM recreates the pathology shapes on the model’s objects, which generates a decision support system for the built environment. The innovation of this research concerns the development of a workflow in which it is possible to automatize the recognition and classification of defects in historical buildings, to finally interpolate this geometric and numerical information with a BIM methodology, obtaining a representation and quantification of the information adapted to the facility management process. The use of innovative techniques such as artificial intelligence algorithms and different plug-ins becomes the main strength of this project.
L’indagine nel sito architettonico-archeologico che fu antico teatro romano sul mare poi trasformatoin ninfeo - erroneamente denominato Tomba di Agrippina - intende affidare alla dimensioneastratta e conoscitiva della rappresentazione la restituzione dei significati del manufatto come‘presenza preziosa’ nel paesaggio urbano di Bacoli. L’approccio di indagine, avvicinandosialla insita dimensione metaprogettuale del rilievo, si propone di suggerire linee di indirizzo permirate strategie di rigenerazione del patrimonio culturale flegreo, laddove l’espansione urbana nonpianificata ci restituisce una mappa territoriale priva di segni di connessione tra le attuali zoneurbanizzate e i resti dei pregevoli manufatti antichi. Diffusamente, e in particolare nel caso inesame, i ritrovamenti archeologici rivelano problematiche compenetrazioni con l’edilizia moderna.I preziosi reperti, spesso ancora parzialmente interrati o inagibili, esigono decisioni e interventidi integrazione che facciano riferimento alle peculiarità territoriali e che, confermandone le azionidi tutela, consentano nuove forme di accessibilità ai siti, attivabili attraverso operazioni dirappresentazione digitale del patrimonio che implementino livelli di fruizione alternativi allavisita diretta.Muovendo da questa esigenza, l’orientamento metodologico della ricerca è inteso ad assumerela digitalizzazione dei processi in ogni fase di lavoro. Obiettivo prioritario è rendere disponibilimodelli tridimensionali del sito, sezionabili ed interrogabili secondo diversi livelli semantici,sia durante la prima fase di acquisizione dei dati (SAPR, TLS), sia in quelle successive dimodellazione (modello virtuale e ABIM) e di consultazione-interrogazione dei simulacri che siprestano a rappresentare in maniera efficace e propositiva il sistema spaziale complessivo e gliapparati figurativi puntualmente esaminati.
Jordan’s architectural heritage has gone through a long period of evolution and development: the result is a mixture of influences and traditions, from both Europe and the Middle East characterised by an optimal integration with the surrounding landscapes, making a great stride to conserve its buildings and historical heritage but has never adopted advanced technologies such as BIM. This is attributable to the lack of specialist training for the professionals within the sector, who remain unaware of the benefits that this methodology can offer. This paper aims to optimise the management process to remedy the natural loss and misplaced historical documentation of heritage over time by creating a 3D library of BIM objects related to typical elements of Jordanian and Arabic architecture, specifically the House of Art in Amman and the Qaqish House in the World Heritage City of As-Salt. This object database, represented through parametric BIM families (easily adaptable to any project of similar elements), will store information related to the geometry of individual objects, but also on the materials and their properties. By creating a library of 3D models of elements typical of the traditional Jordanian architecture, Jordan can acquire attractiveness on the part of tourists and art lovers, starting a chain reaction to get even more digital documentation and heritage conservation of the most historic cities in Jordan and, in general, in the Arabic world.
