“…Emblematic is the progress of 3D printers, more and more used to realise fullyoperational, market-ready products rather than quick and cheap prototypes (The Economist, 2011). Similarly, we are witnessing a 'democratization' and massive spread of 3D digitization techniques (Alderton, 2016;Nancarrow, 2016;Santos et al, 2017), with an increasing demand for hardware and software solutions economically accessible, easily understandable and manageable by almost anyone wills to express his or her creativity through 3D digital products.…”

ABSTRACT:The paper presents a collaborative image-based 3D reconstruction pipeline to perform image acquisition with a smartphone and geometric 3D reconstruction on a server during concurrent or disjoint acquisition sessions. Images are selected from the video feed of the smartphone's camera based on their quality and novelty. The smartphone's app provides on-the-fly reconstruction feedback to users co-involved in the acquisitions. The server is composed of an incremental SfM algorithm that processes the received images by seamlessly merging them into a single sparse point cloud using bundle adjustment. Dense image matching algorithm can be lunched to derive denser point clouds. The reconstruction details, experiments and performance evaluation are presented and discussed.

“…En este contexto, el término "digitalización 3D" se refiere a la captura digital de un objeto 3D con su forma y su apariencia visual desde todos los ángulos posibles (Santos, Ritz, Fuhrmann, & Fellner, 2017). Para este cometido es necesario documentar gráficamente la geometría de los mismos, concediendo cada vez más importancia a la rapidez y precisión en la documentación de los elementos patrimoniales; por lo que la tendencia actual es usar las herramientas más avanzadas en documentación geométrica como es en el caso del método de registro utilizado para este estudio, el escáner láser 3D.…”

Lo más destacado: El ciclo escultórico está constituido por dos grupos dinásticos procedentes de Torreparedones. La técnica de registro 3D empleada para la digitalización del ciclo se ha realizado mediante escáner láser. La aplicación móvil permite de forma intuitiva consultar los modelos tridimensionales de todas las esculturas. Resumen:Los últimos estudios realizados en el conjunto escultórico de época romana del yacimiento arqueológico de Torreparedones (Baena, Córdoba), hallados en el pórtico norte del foro y en el área del templo, ponen de relieve el importante valor arqueológico de las esculturas. Estas investigaciones se han centrado en el registro de datos de sus superficies mediante empleo de escáner láser y en el estudio de la policromía original de algunas piezas, las cuales han sido seleccionadas por su relevancia dentro del conjunto. Con los resultados obtenidos en estos trabajos se procedió a realizar un aplicación gratuita, denominada "Ciclo Escultórico de Torreparedones", disponible para el sistema operativo Android. Esta aplicación permite, de forma intuitiva y fácil, consultar los modelos tridimensionales (3D) de las esculturas, además de poder acceder a una visita virtual en 360º de la sala Roma del Museo de Baena, así como a diferentes contenidos multimedia. El objetivo principal de este trabajo es promover el uso de la realidad virtual en el ámbito del patrimonio, facilitando que el visitante establezca una conexión directa entre el museo y el yacimiento arqueológico. La aplicación desarrollada se configura como una plataforma activa, en la cual pueda incorporarse, de manera científica y divulgativa, los nuevos resultados obtenidos de las investigaciones actuales y futuras.Palabras clave: escultura; época romana; escaneado láser; aplicación móvil; catálogo 3D; visita 360° Extended Abstract:The archaeological site of Torreparedones (Baena) is one of the most outstanding Roman sites in the Province of Cordoba, due to not only the structural remains excavated in recent decades, but also the relevance through the relevance of other recovered materials. In recent years, among the recordings made during excavations and in the area of the north portico of the forum and the temple, an important sculptural group from the high imperial time was documented. The sculptural cycle consists of two dynastic groups, which are currently part of the museum exhibition of Baena. The first, found in the area of the gate, consists of a toga, a female figure, a military sculpture and a fragment ideal statue (of the type hüftmantel). The second group, from the temple or near the same area, consists of two male and female seated statues representing: Divus Augustus, Divus Claudius and Diva Augusta (Livia). The latter offers a representation of idealized types, as characters portraits were produced post-mortem once the senate decreed their deification time. Because of the importance of this second group, a three-dimensional (3D) model of each of the pieces has been created. The main objective of this research, with...

Enhancing heritage fruition through 3D virtual models and augmented reality: an application to Roman artefacts

The spatial characteristics of museum exhibitions may limit visitors’ experience of the artefacts on display. In the case of large artefacts, limited space may affect their whole visualization, or inhibit the visualization of the details farthest from the observer. In other cases, the storage of artefacts in distant sites (museums or archaeological areas) may influence their knowledge process or the possibility for comparative analysis. Moreover, the precarious state of preservation of some artefacts, with damaged or missing parts, makes it difficult to perceive their original appearance. To overcome these limitations, we propose an integrated approach based on 3D virtual models and Augmented Reality (AR) to enhance the fruition of artefacts, improving their visualization, analysis and personal/shared knowledge, also by overcoming space and time constraints. The final AR application is an easily accessible tool for most users from a mobile device, used both inside and outside museums, opening new perspectives for fruition. The framework encourages the use of free and open source software and standard devices, to maximize their dissemination and exploit the potential of such technologies, which is far greater than current use in the cultural heritage field. Selected case studies to test and validate the integrated framework are proposed, dealing with some Roman artefacts found in the area of Modena (Italy). The first is a Roman floor mosaic, found in Savignano sul Panaro (near Modena) in 2011, of which less than half of its original 4.5 x 6.9 m surface is preserved. The others are two Roman funerary lion sculptures: the first is one of two lions flanking the main door of Modena Cathedral, and the second, well-preserved but damaged, is housed in the Museo Lapidario Estense of Modena. Finally, the application was tested by museum experts and visitors both inside and outside the museum, and positively assessed.Highlights:<ul><li>Digital practice is not understood as a prerogative of a small number of people, but as a tool to guarantee and expand artefact fruition, using standard devices and free and open source software.</li><li>Experimentation of new settings to re-contextualize artefacts and establish possible links among them, offering engaging and customized experiences to improve their accessibility and enjoyment.</li><li>Promotion of artefact fruition not only in but also outside museums, such as in a classroom or an open and shared space, opening to new approaches in the fruition of cultural heritage.</li></ul>
