The Use of 3d Scanning and Photogrammetry Techniques in the Case Study of the Roman Theatre of Nikopolis. Surveying, Virtual Reconstruction and Restoration Study.

Abstract

The aim of this paper is to present the specific methods by which 3D scanning and photogrammetric techniques were incorporated into the architectural study, the documentation and the graphic restoration study of the monument of the ancient theatre of Nikopolis. Traditional methods of surveying were enhanced by the use of 3D scanning and image-based 3D reconstruction and 3D remodelling and renderings. For this reason, a team of specialists from different scientific fields has been organized. This presented the opportunity to observe every change of the restoration design process, not only by the use of common elevations and ground plans, but also in 3D space. It has been also very liberating to know how the monument will look like in this unique site after the restoration, so as to obtain at the study stage the best intervention decisions possible. Moreover, these modern work tools helped of course to convince the authorities for the accuracy of the restoration actions and finally to make the proposal clear to the public.

Digital Documentation and 3D Modelling in the Restoration of the First Ancient Theatre of Larissa, Greece

“…It was especially useful in decision-making, as it was possible to draft several restoration scenarios. A similar approach was taken in the case of the roman theatre of Nikopolis (Bilis et al 2017).…”

Quality Assessment of Uav Photogrammetric Archaeological Survey

“…In the literature there are many applications of aerophotogrammetric surveys from UAVs, for Theatres and Amphitheatres from the Roman era, such as the Theatre of Ventimiglia (Nocerino et al, 2013), the Amphitheatre and the Theatre of the Augusta Bagiennorum area (Chiabrando et al, 2011, Bendea et al, 2007, the Theatre and the Amphitheatre of the Pompeii archaeological park , Fiorillo et al, 2016, or outside the Italian context, the Ancient Nikopolis Theatre (Bilis et al, 2017) in Greece or the Amphitheatre of Carnuntum in Austria (Verhoeven et al, 2013). Often, the scale of representation of graphic products, obtained from a photogrammetric process, does not take into account the residues on the Ground Control Points (GCP) and/or Check Point (CP).…”

Toward Hybrid Modeling and Automatic Planimetry for Graphic Documentation of the Archaeological Heritage: The Cortina Family Pantheon in the Cemetery of Valencia

“…More and more attempts are thus being made to develop procedures that combine the best of these two capture techniques as applied to archaeological sites and artefacts. Authors such as El-Hakim et al, (2004), Lambers et al (2007), Yastikli (2007), Al-khedera et al (2009), Remondino et al (2011), Alasino et al (2012, Núñez et al (2013), Colomina and Molina (2014), or Bilis et al (2017), among others, report on "the theoretical background, the methodologies and the latest advances in the documentation procedure, through digital photogrammetry and terrestrial laser scanning" (Lezzerini et al 2016, p. 10).…”
