IMAGE-BASED MODELING TECHNIQUES FOR ARCHITECTURAL HERITAGE 3D DIGITALIZATION: LIMITS AND POTENTIALITIES

Abstract. 3D reconstruction from images has undergone a revolution in the last few years. Computer vision techniques use photographs from data set collection to rapidly build detailed 3D models. The simultaneous applications of different algorithms (MVS), the different techniques of image matching, feature extracting and mesh optimization are inside an active field of research in computer vision. The results are promising: the obtained models are beginning to challenge the precision of laser-based reconstructions. Among all the possibilities we can mainly distinguish desktop and web-based packages. Those last ones offer the opportunity to exploit the power of cloud computing in order to car…

Restituzioni omografiche di finte cupole: la cupola di Santa Maria dei Rimedi a Palermo

Nel vasto repertorio siciliano delle prospettive solide, un ruolo di spicco è ricoperto da un esempio unico di realizzazione di finta prospettiva di cupola sferica su copertura ad arco ribassato, ricavata sull’incrocio del transetto con la navata centrale nella chiesa di Santa Maria dei Rimedi a Palermo. L’unicità di quest’opera sta nella geometria reale della cupola ribassata. Infatti gli esempi più diffusi di finte cupole in Sicilia sono realizzati su soffitti piani lignei o in calcestruzzo. In Appendice 1 si potrà consultare il repertorio delle finte cupole esistenti in Sicilia per la cui stesura ci si è avvalsi degli studi condotti dall’architetto Giuseppe Ingaglio nell’ambito della sua…

Rilievo integrato per la conoscenza e documentazione del complesso termale dell'area archeologica di Tindari (ME)

The aim of this study is to survey the Roman baths integrated in the so-called Insula IV of the archaeological area of Tindari (ME) for a better understanding of the site and for its enhancement. It is a structure that represents one of the oldest and best preserved thermal buildings with retrograde path in Sicily. Taking into account the typological, structural and decorative peculiarities that characterize the site, it was necessary to operate through integrated digital survey methods (laser scanning and SFM), obtaining a 3D model which describes the building in its entirety. The thermal building was inserted in the first century AD in a residential block dating back to the Hellenistic pe…
