“…The use of these digitalized data for applications related to reverse engineering is added to all the applications already mentioned (Fatuzzo, Sequenzia, & Oliveri, 2016;Sequenzia, Fatuzzo, & Oliveri, 2021). Digital photogrammetric surveys and also the data acquired by the use of handheld scans are so accurate that they permit the recreation and replacement of lost fragments using 3D printing techniques, or the manufacture of moulds to reproduce replicas at different scales (Henriques, Bailão, Rocha, & Costa, 2020;Merchán, Merchán, Salamanca, Pérez, & Nogales, 2019).…”

Highlights: The photogrammetric survey demonstrates to be a potential tool in the preventive conservation of ancient plasterworks. The high-precision 3D model allows the study and quantification of alterations (e.g. fissures, deformations, and loss of mass or polychromies). The virtual model and the analysis performed with CloudCompare software provide fast, accurate and accessible results to experts in the field. Abstract: Previous studies and documentation about the state of conservation of architectural or decorative elements are crucial for heritage managers, technicians and researchers to succeed in the maintenance and preservation of the heritage. In this sense, hand tracings, digital drawings, or photographs have traditionally been the methods for alteration and sample mapping. In spite of their effectiveness, these methods have some disadvantages, such as the need for more precision in terms of location, dimensions, quantification and types of alterations. By contrast, high-resolution three-dimensional (3D) models allow us to analyse decorative ancient plasterworks with great precision, offering considerable advantages over traditional tools for heritage documentation. To facilitate stakeholders’ work and enhance the quality of data collected, this work proposes the use of photogrammetry as a tool for the documentation of polychromed ancient plasterworks, taking the upper frieze of the access door to the Charles V ceiling room in the Royal Alcazar of Seville as a case of study. Thus, the work methodology applied has shown several advantages over previous methods. On the one hand, it was possible to obtain a 2D planimetry from the 3D model; this is an essential step for those responsible for heritage, especially in reports prior to restoration interventions. On the other hand, the 3D model created enables present alterations identification, the location of fissures and cracks in their three dimensions (opening, length and depth), deformations measurement and control, the quantification of mass or polychrome loss, and the detached elements digital reconstruction. In this way, highprecision digital results are quickly obtained and accessible to all the experts involved in the heritage conservation and maintenance plan.

“…In particular, interventions were aimed at connecting "the based cracked in two parts, the tree trunk to the body of the Satyr, the right leg with the left heel and, finally, the pine twig on the right side of the forehead" [72] (pp. [8][9]. The connection between the several parts was made with iron bars fixed with lead.…”

“…The technological advances in the architectural field, in particular for the metric surveys [ 5 , 6 , 7 ], offer great advantages as they reduce errors in geometry [ 8 ] and provide results useful for documentation, knowledge [ 9 , 10 ], conservation, and valorization [ 11 , 12 ]. The photogrammetric survey and laser scanning are the most common approaches used for this purpose.…”

The protection of artistic and cultural heritage is a major challenge due to its peculiarities and its exposure to significant natural hazards. Several methodologies exist to assess the condition of artistic heritage and to protect it from exceptional actions. Moreover, novel digital technologies offer many solutions able to deliver a digital replica of artifacts of interest, so that a reduction in the uncertainties in the analysis models can be achieved. A rational approach to the preservation and protection of artistic heritage is based on traditional approaches supported and integrated by novel technologies, so that qualitative and quantitative indicators of the current condition of artistic heritage can be defined and validated in an interdisciplinary framework. The present paper reports the results of an approach to the maintenance and preservation of art objects housed in a museum complex based on a comprehensive digital path towards a Historical Digital Twin (HDT). A workflow aimed at estimating the stress regime and the dynamic properties of two sculptures, based on the detailed three-dimensional model resulting from a laser scanner survey, is illustrated and discussed. The results highlight the great advantages resulting from the integration of traditional and novel procedures in the field of conservation of artistic assets.

“…Technology plays a fundamental role in the safeguarding of cultural heritage, providing new multidisciplinary methods that contribute to improving conservation tasks (Merchán & Pérez 2020). The conservation and enhancement of cultural heritage has improved substantially since the development of digital technologies, such as digital photogrammetry and the use of laser scanners (Sequenzia et al 2021). In addition to these two techniques, there is a more recent one, known as Mobile Mapping Systems (MMS), based on SLAM technology (Simultaneous Localisation and Mapping) (Benavides-López & Barrera-Vera, 2020).…”

<div data-canvas-width="631.2">Los estudios de conservación sobre un bien arquitectónico constituyen un soporte sólido para futuras intervenciones. En concreto, la Gestión Cartográfica Digital aboga por el uso de modelos simplificados que permiten alcanzar distintos niveles de definición, según la escala arquitectónica deseada. Partiendo de estudios previos en los que se han logrado obtener cuatro niveles de definición, se tiene como objetivo definir un quinto nivel a partir de un modelo 3D. Para ello, se propone como caso de estudio la Muralla de La Macarena (Sevilla). En este trabajo se realiza el levantamiento fotogramétrico de un tramo del sector de esta muralla medieval, a partir del cual se identifican las entidades que formarán parte de un quinto nivel de definición.</div>
