3D metric Survey of the Mezzagnone Arab bath. From point clouds to 2D drawings and parametric model

Abstract

The presented work reports the results of a multiscale and multi-sensors 3D metric survey achieved on the Arab Bath of Mezzagnone, an archaeological site in Sicily (Italy). Aerial and terrestrial techniques were combined to obtain detailed documentation of the selected asset and to explore the latest advancements in the archaeological heritage documentation domain. Specifically, the integration of Uncrewed Aerial Vehicles (UAV) photogrammetry using both nadir and oblique acquisitions, along with Terrestrial Laser Scanning (TLS) technology, was used for detailed documentation of the whole site. The aim of the research consists in obtaining a foundation for documentation, study, restoration projects, and public promotion through the creation of a 3D model of the site, traditional 2D drawings, digital orthoimages, and a parametric model of the studied object. In the work, the adopted pipeline, from data acquisition to the final results, will be described with the evaluation and validation of the achieved accuracies.
