3D IMAGE-BASED SURVEYING OF THE SAFE OF THE OBELLIO FIRMO DOMUS IN POMPEII

Abstract

Abstract. This paper shows an application of image-based 3D modelling concerning an interesting case study in the field of Cultural Heritage, a safe located in the Obellio Firmo domus in Pompeii (Italy), one of the largest and most complex houses in the ancient city. The object was strongly deformed by the eruption of Vesuvius in 79 A.D. and is currently protected by a permanent glass that helps to preserve it over time. The surveying activities and processing methodology is explained, based on Multi-View Structure from Motion technique, as well as the unconventional solution adopted during the images acquisition. Finally, an attempt will be presented to reconstruct the hypothetical original three-dimensional appearance and shape of the safe.

“…The adequate and feasible responses to this critical digitisation request are undoubtedly dependent on the diversified purposes and often not aimed at specific objectives but, at the same time, destined for multiple uses and purposes. In general, the fine-tuning of image and range-based methods are aimed at obtaining very high geometric and radiometric resolutions to support specialised studies (Francolini et al 2020), for diagnostic purposes and evaluation of the state of conservation (Donadio et al 2018), for restoration operations (Girelli et al 2019), to obtain parametric datasets (Patrucco et al 2019) or 3D printing (Balletti et al 2017). In the context of studies aimed at developing geomatics technologies, significant emphasis has been given to low-cost solutions, often based on structured light scanners (Kersten et al 2017), and integrated solutions for arranging the massively detailed digitisation of museum-preserved objects (Ritz et al 2017).…”

From 3D surveying to replica, a resource for the valorisation of museum artifacts. The case of the bas-relief of Giovanni da Legnano in Bologna.

“…In fact, the 3D model of an object ensures the memory of its current state, but there is much more beyond this. A virtual digital 3D model can be explored, transformed, sectioned, studied in all aspects, without touching or damaging the real object; for example, the decay can be mapped to plan the restoration [3], artworks in different locations can be compared with each other [4], a damaged object can be virtually bring back to the original splendor [5], the peculiar characteristics of the object can be emphasized, such as inscriptions [6], permitting new levels of knowledge to those offered by the real object.…”
