A COMPARISON BETWEEN TLS AND UAV TECHNOLOGIES FOR HISTORICAL INVESTIGATION

Valenti, R.; Paternò, E.

The architectural and sculptural value of the investigated Cultural Heritage has suggested a variety of possible approaches ranging from the traditional modus operandi to the implementation of innovative technology. The conducted research implemented digital and automatic photogrammetry software using Structure from Motion or SFM. These techniques which involve the convergence of different disciplines, such as Computer Vision and photogrammetry seek to generate 3D models, that is the mathematical representation of the investigated 3D objects. The integration of UAS, photogrammetry and TLS develops 3D models able to provide more detailed information. The main purpose of the present research is to test the potentialities offered by the new survey and 3D processing systems in order to carry out historical analyses and investigations in closed environments and for small scale architecture. Starting from the acquired data, the 3D models of the altars allow a 3D comparison between the works object of study and Pozzo’s treatise, also allowing speculation about their possible relations, providing extraordinary outcomes from the point of view of survey integrated methodologies and from the point of view of historical and geometric interpretation.
