Un progetto di Archeologia Virtuale a Soknopaiou Nesos nella regione del Fayyum: stato dell’arte e prospettive di ricerca

2016

This work illustrates the first results of the Project of Virtual Archaeology which is now developed by a team of topographer from Salento University (Lecce) together with the équipe of Archaeological Mission of Centro di Studi Papirologici at Soknopaiou Nesos (Fayyum, Egypt). Article also focuses on the main aims of this project : a topographical survey and virtual reconstruction of monuments, digital analysis of data, representation of urban and suburban landscape and their evolution, achievement of a special platform for using the data both on-line and off-line. Keywords : Virtual Archaeology, Soknopaiou Nesos, Archaeological Mission.

New metric products, movies, and 3D models from old stereopairs and their application to the in situ palaeontological site of Ambrona

2020

3D modelling tools from photographic pictures have experienced significant improvements in the last years. One of the most outstanding changes is the spread of the photogrammetric systems based on algorithms referred to as Structure from Motion (SfM) in contrast with the traditional stereoscopic pairs. Nevertheless, the availability of important collections of stereoscopic registers collected during past decades invites us to explore the possibilities for re-using these photographs in order to generate new multimedia products, especially due to the fact that many of the documented elements have been largely altered or even disappeared. This article analyses an example of application to the …

The Augmented Reality as an Instrument for the Representation/Visualization of Architecture

2019

This paper deals with issues related to the representation/visualization of architecture and its narration through the augmented reality tools. Specifically, the possible scenarios and the different strategies to address the problems related to the application of AR platforms in the field of cultural heritage are presented. Some case studies will be analyzed and the use of augmented reality applied to museums and archaeological sites including the Museum of the Cité de l'architecture et du patrimoine in Paris, the Regional Archaeological Museum A. Salinas in Palermo and the archaeological site of Selinunte. Thanks to these exemplary cases, the potential and critical aspects of the latest AR…

Exploiting 3D Modelling and Life Cycle Assessment to Improve the Sustainability of Pavement Management

2020

Today road agencies worldwide face difficult decisions for construction, maintenance and rehabilitation of their road infrastructure as they try to balance limited budgets. This is further complicated rising environmental concerns over equipment and techniques used for these practices. This has led agencies to consider alternative approaches for smarter and sustainable pavement asset management systems. This paper considers the use of a low-cost 3D image modelling distress identification and classification proposal for data acquisition and analysis. To establish its environmental friendliness, a case study in Palermo, Italy, is considered wherein a Life Cycle Assessment (LCA) exercise is do…

Will drawing be used to study and teach architecture in the next century?

2022

In this millennium, the use of digital tools for representation (and survey, but the subject will not be discussed here) has rapidly and deeply modified the study and the design of architecture. The rapid evolution of this mutation prompts the following question: will drawing be the language of the architect in the next century?

Modelli interoperabili per Cultural Heritage Recording. Le cupole a torrini di Sicilia e Castiglia.

La ricerca indaga l’origine e l’evoluzione di uno specifico modello di cupola su tamburo a pianta circolare o poligonale, con contrafforti cilindrici sull’asse dei piloni della crociera. Sei casi studio in Spagna e in Sicilia sono stati studiati attraverso il riesame delle fonti storiche e sono state analizzate le matrici geometriche sottese al progetto; i casi studio ancora esistenti sono stati rilevati con metodi laser scanning e fotogrammetrici. I modelli tridimensionali sono stati utilizzati per una verifica del contributo statico offerto dai torrini alla stabilità delle strutture. The research work is focused on the origin and the modifications of a peculiar dome on tambour having a ci…

Helena Niemirowska Syrkus: Graphic analysis of the ‘House of Dr Nelken in Warsaw’

2017

In 1920s and 1930s, Warsaw was becoming one of the hubs of propagation of the new architecture, thanks to the geographical contiguity with the Weimar Republic, which allowed the formation of young minds aimed at a blending of architecture, art and music. In this cultural context, a young Helena Niemirowska Syrkus supported the idea that urban planning and architecture, conceived as art forms, had to target at the definition of a language able of expressing the great revolutionary step achieved in the social, economic and political life of that time, through new configurations. According to Helena Niemirowska, who shared the avant-garde thesis, to become an artist the modern architect had to…

HIGH QUALITY TEXTURE MAPPING PROCESS AIMED AT THE OPTIMIZATION OF 3D STRUCTURED LIGHT MODELS

2019

Abstract. This article presents the evaluation of a pipeline to develop a high-quality texture mapping implementation which makes it possible to carry out a semantic high-quality 3D textured model. Due to geometric errors such as camera parameters or limited image resolution or varying environmental parameters, the calculation of a surface texture from 2D images could present several color errors. And, sometimes, it needs adjustments to the RGB or lightness information on a defined part of the texture. The texture mapping procedure is composed of mesh parameterization, mesh partitioning, mesh segmentation unwraps, UV map and projection of island, UV layout optimization, mesh packing and mes…

RPAS AND TLS TECNIQUES FOR ARCHAEOLOGICAL SURVEY: THE CASE STUDY OF THE ARCHAEOLOGICAL SITE OF ERACLEA MINOA (ITALY)

2018

Abstract. Digital documentation and 3D modelling of archaeological sites are important for understanding, definition and recognition of the values of the sites and of the archaeological finds. The most part of archaeological sites are outdoor location, but a cover to preserve the ruins protects often parts of the sites. The possibility to acquire data with different techniques and merge them by using a single reference system allows creating multi-parties models in which 3D representations of the individual objects can be inserted. The paper presents the results of a recent study carried out by Geomatics Laboratory of University of Palermo for the digital documentation and 3D modelling of E…

3D survey in complex archaeological environments: An approach by terrestrial laser scanning

2018

Abstract. The survey of archaeological sites by appropriate geomatics technologies is an important research topic. In particular, the 3D survey by terrestrial laser scanning has become a common practice for 3D archaeological data collection. Even if terrestrial laser scanning survey is quite well established, due to the complexity of the most archaeological contexts, many issues can arise and make the survey more difficult. The aim of this work is to describe the methodology chosen for a terrestrial laser scanning survey in a complex archaeological environment according to the issues related to the particular structure of the site. The developed approach was used for the terrestrial laser s…
