The Amphitheatre of Avella: From Its Origin to Digital
Abstract
This study is a collaboration between the Superintendence of Archaeology, Fine Arts and Landscape of the districts of Salerno and Avellino, particularly the Avella’s Archaeological Office, and the departments of Sciences of the Cultural Heritage and Civil Engineering of the University of Salerno, to serve the purposes of protection, research and enhancement of the Avella’s monument. The paper deals with the photogrammetric survey of the ancient Amphitheatre of Avella (Italy) made by an UAV aircraft, which weighs under 2 kg. The ultimate goal is the realization of georeferenced orthophotos. Two capture modes were compared each other: firstly, a traditional photogrammetric flight with overlap of about 75%, consequently a less established video acquisition. The generated 3D models are verified metrically through 6 GCP (Ground Control Point) placed on the arena floor. The results show that video techniques, although characterized by further margins of error, have the advantage of speed of acquisition and secure overlap between the frames, allowing to monitor the cultural heritage with an extreme ease of operation.
