Conservazione e ricostruzione sostenibile dei centri storici: definizione di nuove metodologie di intervento attraverso l’integrazione di modelli 3D complessi e Sistemi Informativi Architettonici
No full textIl contributo illustra una sperimentazione legata all’uso dei GIS 3D finalizzati al controllo degli esiti progettuali in situazioni critiche, quali le reintegrazioni di lacune architettoniche e urbane in alcuni centri storici dell'Abruzzo montano. Tale ricerca è stata sviluppata a seguito delle criticità evidenziate nel corso della redazione dei Piani di Ricostruzione di tali comuni, strumenti normativi indispensabili per la ricostruzione del territorio aquilano colpito dal sisma del 2009.The paper illustrates an experiment carried out with the use of 3D GIS project aimed at checking the planning results in critical situations, such the reintegration of architectural and urban lacunas in some historical centers of the Abruzzo mountains. This research was developed as a result of issues raised during the drafting of the Reconstruction Plans of this villages, such regulatory tools needed for the reconstruction of area affected by the 2009 L'Aquila earthquake
Tra strumenti classici e geodatabase 3D: il piano di ricostruzione post sisma 2009 del centro storico di Bugnara (AQ)
No full textLa "Carta di Londra" e il Patrimonio Architettonico: riflessioni circa una possibile implementazione
No full textIl rapido sviluppo delle ICT e la crescente disponibilità di strumentazioni e software anche a basso costo ha consentito, ad una vasta piattaforma di utenti, di sperimentare le potenzialità offerte dalle tecnologie digitali a servizio del Patrimonio Culturale. La conseguente grande diffusione di rappresentazioni digitali ha portato, dopo un lungo percorso, nel 2009, alla stesura della “Carta di Londra” che ha l’obiettivo di stabilire dei principi metodologici generali per le applicazioni di visualizzazione digitale nel settore della ricerca e della comunicazione dei Beni Culturali. I “Principi di Siviglia” rappresentano una implementazione della Carta di Londra, specificamente riferita al campo dell’archeologia. L’esperienza condotta può rappresentare un interessante riferimento per il campo dell’architettura, per il quale, tuttavia, sembrano necessarie alcune riflessioni di ordine disciplinare e metodologico. Pertanto il contributo vuole offrirsi come base di riflessione sulla possibilità di declinare i principi della “Carta di Londra” al settore dell’architettura storica e, più in generale, sulle problematiche ed opportunità offerte dalle tecnologie e strumentazioni digitali nel rilievo, visualizzazione e rappresentazione dei Beni Architettonici.The rapid development of ICT and the increasing availability of low cost tools and software for a wide platform of users have favored the studying of the possibilities given by digital technologies applied to Cultural Heritage. The consequent widespread use of digital representations of Cultural Heritage led in 2009, after a long process , the drafting of “The London Charter" which aims to establish general methodological principles for digital visualization in the research and communication field of Cultural Heritage. The “Principles of Seville” represent an implementation of the London Charter, specifically related to archaeology. The gained experience should be an interesting reference for the architectural field, for which, however, it seems necessary some disciplinary and methodological considerations. Therefore the paper want to be a base point to develop a consideration on the opportunity to decline the principles of “The London Charter” in the architectural heritage field and, more generally, on the issues and opportunities offered by advanced digital technologies and tools for architectural heritage surveying, visualization and representation
Dal rilievo del danno sismico al disegno per il progetto di restauro: un’applicazione di documentazione speditiva in condizioni di emergenza
No full textIn seguito all’esperienza di rilievo del danno sul patrimonio culturale compiuta in occasione del terremoto del 2009 in Abruzzo, si sono sperimentate le tecnologie disponibili di modellazione 3D
basate su immagini digitali. In condizioni di pericolosità o difficile accessibilità dell’oggetto da rilevare, tali tecniche rappresentano un valido supporto per effettuare una documentazione di dettaglio in maniera speditiva. Nel caso presentato la procedura di modellazione 3D viene testata
in fase di cantiere (restauro di un palazzo quattrocentesco a L’Aquila), in occasione del rinvenimento di alcune decorazioni pittoriche in un ambiente finora inaccessibile, la cui fruibilità in futuro pone
rilevanti questioni conservative. La documentazione dello stato di fatto pertanto costituisce una
base informativa essenziale per il progetto di restauroFollowing the experience made by survey of seismic damage on cultural heritage, during the 2009 earthquake in the Abruzzo region, we have
tested techniques, currently available, of 3D modeling based on digital images. The intention is to document situations of particular complexity, it is advisable to perform a detailed and rapid documentation (due to hazardous conditions or
difficult accessibility of the detected object). The
three-dimensional modeling procedure tested here at work (restoration of a fifteenth-century palace in L’Aquila), when some pictorial decorations were discovered in a location so far inaccessible, (whose enjoyment in the future poses
significant conservative issues). The documentation of the status quo, in this case, is an essential starting point for the conservation project
From ‘monument medical records’ to 3D GIS for historic architecture documentation
No full textHistoric architecture documentation and complex data set management needed for architectural heritage
conservation are a problem that both theoretical and empirical research have continued to tackle since the
Nineties. Following the first experiments to utilise “monument medical records” advocated by Giovanni Urbani
and Michele Cordaro, carried out over a decade ago, we look at some more recent developments of research
conducted into documentation systems to support architectural heritage conservation.
This paper also illustrates how the new opportunities offered by the rapid development of information
technology for the representation of cultural heritage (image-based modelling, cloud computing and SfM)
provide very effective tools for documenting the state of conservation of cultural heritage and completed
restoration work. The use of such tools allow the concept of “monument medical records”, initially plotted as
two-dimensional representations of an architectural structure (e.g. “medical record” of St. Mary of Collemaggio
in L’Aquila and other applications) to the true three-dimensional substance of architecture, broken down into its
smallest elements, queried and displayed three-dimensionally. This breakdown can provide an increased amount
of informative content that, although making the process more laborious, is designed to document the heritage
requiring preservation in more detail
Dal rilevamento integrato al SiArch-3D: il caso di studio della chiesa di S. Paolo a Peltuinum (AQ)
No full textFrom integrated surveying to SiArch-3D: the case-study
of S. Paolo church in Peltuinum (AQ). The church of S. Paolo near Peltuinum (AQ) has been chosen as case study to test the SiArch, i.e. the Architectonical Informative
System studied by the Research Unit of L'Aquila University. Before the earthquake of ApriI 6th 2009, happened during the research period, the building was surveyed using digital photogrammetry techniques by PhotoModeler Scanner 6 software. After the seismic event the church was surveyed
with laser scanner. About architectonical surveying, according to the used instruments, digital photogrammetry techniques
are simpler, faster and more economie, but surfaces built by photogrammetric point clouds are satisfying only for flat façades or with regular curvature, and elements with limited
prominence. Using all surveying data, was reelised the church's 3D photorealistic model. To build an Architectonical Informative System, the first step is planning the database, that required
to compose 3D model according to constructive elements. Then the 3D model, textured by Autodesk 3DStudioMax
20 1Oand exported in *.3ds format, is imported in ArcScene of ESRI ArcView 9.3 software. This procedure gives the possibility to realize an architectonical informative system with photorealistic 3D model into GIS environment. Moreover another testing is about the importation of churciis mesh textured surface, realized by digitaI photogrammetry techniques, into ESRI GIS environment
