Abstract

This study is a collaboration between the Superintendency 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 the UAV aircraft, which weights under 2 kg. The ultimate goal is the realization of a georeferenced orthophotos. Two capture modes were compared each other: the first was a traditional photogrammetric flight with overlap of about 75%, consequently it was decided to test the possibilities offered by video acquisitions. The generated 3D models are verified metrically, through 6 GCP (Ground Control Point), placed on the arena floor. The results show that the video acquisition techniques, although characterized by further margins of error, show the advantage of acquisition’s speed and secure overlap between the frames, allowing to monitor the cultural heritage with an extreme ease of operation.
