Abstract

Abstract: The present paper shows that is possible to record archaeological sites using 4k videos from UAVs. The here described methodology starts with the decomposition of the videos in the original frames. Considering that the recording of videos is taken at a regular pace the extracted frames can be selected in different patterns to assure a proper photogrammetric restitution. In this paper, we have tested different configurations (overlapping of frames and the number of ground control points) to design an efficient protocol. The results show that the method is suitable for surveying large sites and that 4k videos can be a reliable source for producing accurate cartographic products (digital terrain models and ortho-images).
