UAV and Computer Vision in 3D Modeling of Cultural Heritage in Southern Italy

Abstract

Abstract:On the Waterfront Italo Falcomatà of Reggio Calabria you can admire the most extensive tract of the walls of the Hellenistic period of ancient city of Rhegion. The so-called Greek Walls are one of the most significant and visible traces of the past linked to the culture of Ancient Greece in the site of Reggio Calabria territory. Over the years this stretch of wall has always been a part, to the reconstruction of Reggio after the earthquake of 1783, the outer walls at all times, restored countless times, to cope with the degradation of the time and the adjustments to the technical increasingly innovative and sophisticated siege. They were the subject of several studies on history, for the study of the construction techniques and the maintenance and restoration of the same. This note describes the methodology for the implementation of a three-dimensional model of the Greek Walls conducted by the Geomatics Laboratory, belonging to DICEAM Department of University "Mediterranea" of Reggio Calabria. 3D modeling we made is based on imaging techniques, such as Digital Photogrammetry and Computer Vision, by using a drone. The acquired digital images were then processed using commercial software Agisoft PhotoScan. The results denote the goodness of the technique used in the field of cultural heritage, attractive alternative to more expensive and demanding techniques such as laser scanning.

Uav Photogrammetry for Cultural Heritage Preservation Modeling and Mapping Venetian Walls of Bergamo

“…Stek discuss the potentiality of survey by drones for discovering archaeological remains under the soil surface (Stek, 2016). Barrile describes the adopted methodology for elaborating a 3D model of the Greek Walls of Reggio Calabria starting from the images acquired by drones (Barrile et al 2017). Particularly relevant to the research on Bergamo city walls is the research made by Barazzetti, who discuss a working method for extracting Orthographic projections from pictures acquired by drones (Barazzetti et al 2014).…”

Generation of high quality 3D models of a monastery located in Western Greece

“…At the same time, some researchers focused on assessing geohazards and surface deformation at cultural heritage sites in order to develop effective conservation plans using UAV imagery 18,19 . However the majority of studies focuses on deriving 3D models of cultural monuments or building elements 20,21,22,23 . In particular, NGB (NIR + Green + Blue), Red Edge, and Thermographic cameras mounted on UAVs were utilized to create 3D models of numerous archaeological sites, which were subsequently 3D printed using different materials to obtain a small scale representation the monument 21 .…”
