Abstract

This paper illustrates the experiment of image-based modelling conducted on the site of Calicantone (RG) by the international course in Archaeology of the Dipartimento di Scienze Umanistiche of the University of Catania, in collaboration with the Dept. of Engineering and Architecture of the same University and the Soprintendenza of Ragusa. The aim of the research was to experiment and verify a single process of digital acquisition, elaboration and communication, and to investigate the potential of shifting from 3D to 2D for the creation of metrically and geometrically reliable orthophotos (so called new photogrammetry). In particular, this kind of application has not been widely used by the archaeological teams working in Sicily, especially when the Computer Vision is not aimed at the reconstruction or the dissemination of the results. The site of Calicantone represented an ideal context for a multiple experimentation of image-based modelling. Indeed, the construction of a methodology of survey of the site involved a global understanding of a complex context, made by different kinds of evidence: built architecture (walls), negative architecture (rock cut tombs), horizontal restitution of the trenches vs vertical restitution of the slopes of the hill hosting the tombs. From the point of view of the archaeological narrative, the exceptional impact of the landscape, the necessity of an enhancement and the limited visibility of some of the archaeological evidence encouraged the acquisition of the data through passive detectors, in order to support the traditional 3D reconstruction of the landscape.
