Towards a 3D digital model for management and fruition of Ducal Palace at Urbino. An integrated survey with mobile mapping
Full text linkThe digitization is the first feat of safety, knowledge and management of Cultural Heritage. The technological development has produced a complexity increase to manage the big data acquired. This paper shows the best practices for the digitization of a museum (National Gallery of Marche), hosted in a historical and complex building: it's a problem of contents and "container" (the Urbino Ducal Palace = a city in the appearance of a Palace). This is the case study of the first challenging aim of the CIVITAS project. The digitization workflow has combined the several sensors and technology at different scales, such as static and mobile wearable laser scanners systems, the different focals for internal and external cameras, 360 panoramas and HD images. The goal achieved is the new 3D digital model, validated and with high accuracy, containing big 3D data, as starting point of HBIM, Serious Games, VR/AR applications

No full textThe Arch of Ancona is one of the material symbols of the Maritime Heritage of the port-city. Built entirely of marble, the Arch stands in the area of the new port infrastructures and is undoubtedly the oldest and most famous architectural object in the Marche Region. The results of the integrated digitalisation have shown how fundamentally important the Digital Twin is for its conservation and enhancement since it provides the accuracy required to understand and interpret its deterioration and ensure that physical barriers are overcome so that sustainable tourist strategies can be implemented
3D change detection for cultural heritage monitoring: Two case studies of underground sculptural reliefs
No full textThe preservation of underground cultural heritage is a challenging goal. Difficult acquisition conditions, the need for uniformity of temporal data and the speed at which surfaces change are some of the issues to consider. Also, quantifiable three-dimensional data are often unavailable when assessing changes on sculptural reliefs because traditional records are two-dimensional. In this paper, we present a workflow to easily detect and measure 3D superficial changes in sculptural reliefs using the deviation analysis technique. We compared multitemporal surveys, testing a quantitative, replicable, and verifiable procedure in two case studies: the reliefs of Pakal’s Tomb at Palenque, Mexico, and those of the Osimo Caves in Italy. Both are located underground and show similar superficial alterations such as material disaggregation, efflorescence, salt crusts, and biological colonization. The reliefs showed visible and quantifiable changes on the deviation maps. The procedure to detect changes can be implemented with models generated by structured light scanning as well as photogrammetry
ANALYSIS, THEMATIC MAPS AND DATA MINING FROM POINT CLOUD TO ONTOLOGY FOR SOFTWARE DEVELOPMENT
No full textThe primary purpose of the survey for the restoration of Cultural Heritage is the interpretation of the state of building preservation. For this, the advantages of the remote sensing systems that generate dense point cloud (range-based or image-based) are not limited only to the acquired data. The paper shows that it is possible to extrapolate very useful information in diagnostics using spatial annotation, with the use of algorithms already implemented in open-source software. Generally, the drawing of degradation maps is the result of manual work, so dependent on the subjectivity of the operator. This paper describes a method of extraction and visualization of information, obtained by mathematical procedures, quantitative, repeatable and verifiable. The case study is a part of the east facade of the Eglise collégiale Saint-Maurice also called Notre Dame des Grâces, in Caromb, in southern France. The work was conducted on the matrix of information contained in the point cloud asci format. The first result is the extrapolation of new geometric descriptors. First, we create the digital maps with the calculated quantities. Subsequently, we have moved to semi-quantitative analyses that transform new data into useful information. We have written the algorithms for accurate selection, for the segmentation of point cloud, for automatic calculation of the real surface and the volume. Furthermore, we have created the graph of spatial distribution of the descriptors. This work shows that if we work during the data processing we can transform the point cloud into an enriched database: the use, the management and the data mining is easy, fast and effective for everyone involved in the restoration process

Ideal geometries in the military architecture of F. di Giorgio Martini. the defence system fortress-tower of Cagli
No full textThe subject of the military architecture was widely studied and analyzed by the architect Francesco di Giorgio Martini (1439-1501), who created important defensive works in the duchy of Montefeltro. A defensive line connects a series of medieval villages of the Marches: b Between the Martini's fortifications, Cagli has still a fortified tower perfectly preserved and some traces of the fortress. The analysis conducted on them involves the information inferable by the essay, by historical surveys and the recent laser scanner survey. The aim of the research was to identify the generating geometry of the architecture: taking the precepts of Vitruvius, in the Renaissance period geometry was synonymous with proportion, order and symmetry. Two are subjects: the first one is the in-depth knowledge of the tower through the digital data obtained from the point cloud, the other one is the reconstruction of a global image of the complex tower-fortress
ICT driven platform for high-quality virtual contents creation and sharing with e-Tourism purposes. The interreg IT-HR REMEMBER project
No full textThis paper describes REMEMBER, an EU project which aims at establishing a network for joint valorization of 8 ports in Italy and Croatia, trying to shift the paradigm of touristic flows toward a sustainable tourism. The key point is an innovative ICT architecture, modular and scalable, to share information at different system levels of detail and fruition, with an interoperable and multi-channel approach. Given its flexibility, contents can be conveniently displayed in different ways: Web portals, fixed installations, mobile devices etc. This infrastructure enables a great number of Digital Experiences (DEs) that can be exploited at both global and local scale. Since the project is on going, the paper presents a first overview of the instantiate methodology, as well as briefly introduces the DEs that are currently designed and, finnaly, reports a prospective outlook related to the post-pandemic scenario

No full textLa digitalizzazione del patrimonio culturale è un processo multidimen-sionale necessario per salvaguardare i beni storico-artistici, per averne una cono-scenza profonda e per gestirli nel modo più completo possibile. Il caso studio presentato mostra il primo stimolante obiettivo di un progetto di ricerca multidi-sciplinare che intende migliorare un oggetto architettonico esemplare a partire dalla sua completa digitalizzazione e proporre soluzioni di godimento multisen-soriale. Questo articolo mostra i primi risultati nel campo del rilievo architetto-nico, della modellazione e della parametrizzazione. L'integrazione di diverse tec-niche è necessaria per ottenere un prodotto finale valido che possa costituire una base per la conservazione e la valorizzazione del Patrimonio Culturale. Il flusso di lavoro della digitalizzazione comprende sensori e scale diverse, come laser scanner statici e portatili, immagini 360 e HD. L'obiettivo raggiunto è un modello digitale, scientificamente validato, ad alta accuratezza che contenga dati 3D e che si configuri come punto di partenza per la ricostruzione delle fasi storiche dell'ar-tefatto e per le applicazioni VR / AR. La ricerca mostra un approccio solido e interdisciplinare applicato al caso studio: le attività e le sfide affrontate indicano che possono dimostrare problemi multilivello
THE INTEGRATED SURVEY OF NARROW SPACES AND UNDERGROUND ARCHITECTURE: THE CASE STUDY OF CAMPANA CAVES BAS-RELIEFS
Full text linkItalian Cultural Heritage is rich in fascinating Underground Heritage (UH) to be protected and preserved because of its fragility and historical importance. An accurate and high-resolution 3D model is essential to reach an appropriate level of knowledge to safeguard caves but there are several obstacles to face. Underground data acquisition and following elaborations are problematic due to environmental conditions such as lack of homogeneous light sources, highly absorbing and unstable surfaces, narrow spaces and complex geometry. For these reasons, the integration of different techniques is mandatory to achieve a valid final product that could be an important basis for consolidation, preservation and valorization of the UH. In this paper, an integrated survey method is tested for a realistic digital reconstruction of hypogeal spaces. In addition to outputs for experts of conservation, the creation of multimedia products for a wider audience of non-professionals users is investigated as a way to preserve UH from decay. Thanks to VR, visitors virtually walk through the underground galleries observing and interacting, making accessible also fragile environments with forbidden access due to preservation policies
