Abstract:

In the last few years 3D laser scanning techniques have been used more frequently as a means for recording archaeological evidence. By contrast, 3D reconstructions, more often than not, serve purely educational purposes, and their efficiency for scientific analysis is disregarded. A combination of the two approaches supports the likely transition of the virtual reproductions; extending them to the interest of varied categories of users. This paper puts an emphasis on the process of reconstructing the Roman Baths of Edeta, Lliria. It shows the capabilities of the 3D Laser scanning approach of using accurate digital data derived from the real evidence and the restoration of the different locations and shapes of the feature during the past. Additionally, 3D virtual reconstruction is used to further analyse the site and, eventually, be used to extend the general public's knowledge of its cultural heritage through highly realistic images.

Introduction

Computer Graphics has completely converted the traditional archaeological recording system. Currently, “Digital Archaeology” would be the best term to refer to it (Earl et al. 2012). Whether the information concerns spatial data or physical remains, drawings or pictures of the sites, they are archived and processed as digital information.

Thanks to the scholars involved in the process of preservation and conservation of the site, the archaeological data derived from the Roman Baths of Edeta have been recorded following this digital methodology. The work has culminated with the introduction of realistic virtual restoration of the edifices, principally focusing on educational purposes.

The hypothetical restoration has been generated taking advantage of accurate spatial data captured through 3D Laser Scanning. The use of this technology as well as other significant digital information of the site, has likely turned realistic 3D virtual models of Roman buildings into useful data. In fact, the visualisations might be appreciated not just by amateurs of history or inexpert users, but also by scientists involved in the analysis of the archaeological evidence.

Virtual development of raw geometry, traditionally recorded using photogrammetry, CAD drawings or even 3D Laser Scanning, has never been performed without criticism by experts (Lock 2003).
