La cornice Ionica del tempio G di Selinunte. Rilievo e interpretazione per la ricostruzione virtuale.
2013
This research is focused on the virtual reconstruction of the Ionic cornice of temple G of Selinunte, as a case study for the definition of a virtual reconstruction method of collapsed walls elements in archaeological contexts. The complexity of the ruins of the temple suggested a thorough archaeological analysis of the fragments of the Ionic cornice that made it possible to identify traces of the construction process left by stonecutters during the worksite such as unfinished surfaces. The study of these surfaces, together with the dimensional data surveyed, provided the information to reposition the fragments in their supposed original position, and thus develop a virtual reconstruction o…
Reconstruction of urban sites from photos
2019
Abstract. This paper reports the results of an experiment that aims at the virtual reconstruction of a urban site that has been partially reshaped during the 20th century; the reconstruction process is based on period photos. The chosen case study is the eldest harbour of Palermo, named ‘Cala’; the site was bombed during World War II and new buildings took the place of the ruined ones. Two period photos, taken from an aircraft, document the buildings that were destroyed by bombs. The 3D restitution process used the ‘inverse’ projection from period photos (2D) to the virtual space (3D) ; the first step was therefore addressed to the calculation of the inner parameters (focal length, principa…

La ricostruzione da immagini con tecniche di restituzione prospettica
2018
Il contributo è incentrato sulla ricostruzione di opere di architettura perdute da fotografie attraverso l’uso di tecniche di restituzione prospettica. Una breve introduzione illustra le ragioni che relegano la restituzione prospettica a un ruolo secondario nel contesto delle ricostruzioni virtuali; il paragrafo successivo illustra i risultati di un test sul confronto fra restituzione prospettica da singolo fotogramma e restituzione SfM. Il paragrafo conclusivo descrive la ricostruzione virtuale di una chiesa di Palermo, demolita nella prima metà del XX secolo e documentata da poche foto d’epoca. The paper focuses the 3D reconstruction of buildings that were destroyed during the World War I…
Lettura stratigrafica delle murature e studio architettonico della Chiesa
2018
The contribution concerns the study of the construction phases of the church of Santa Marina in Muro Leccese (LE) realized through the stratigraphic reading of the masonry that has allowed, later, to be able to carry out the reconstructive study of the building through a digital model.
