dc.description.abstract | [EN] Extended Abstract:Ali Atar, Warden of Loja and Lord of Zagra, was born around 1393. He was one of the principal military leaders of the Nasrid period and came to join the Grenadine Royal House by marrying his daughter Moraima with Boabdil, the last King of Granada. He died in the battle of Lucena in 1483, where one of the magnificent jineta swords of Andalusí manufacture was snatched, which is now conserved and located in the collection of the Toledo Army Museum (MUSEJE). The MUSEJE collections house important scientific, technical, historical and artistic heritage. The historical military heritage needs for its protection, preservation and valorisation the adaptation of new resources and benefit from the usage of new digital technologies. The physical conservation is no longer enough for a resource as valuable as cultural heritage; it needs to be complemented with a comprehensive digital preservation in all its forms, being essential and necessary for its proper safeguard. The virtual era currently emphasizes its presence in the digital documentation, preservation and dissemination of our cultural heritage. In particular, we have oriented and activated it on the historical military heritage, knowledgeable and narrator of our history, of its treasures, and of their relationship within the society as important representations of social and dynastic status. This paper is centred in the 3D digitisation by means of digital photogrammetry and 3D modelling of a historical military weapon. Aided by photogrammetry and information and communication technologies (ICT), we will achieve precise geometric documentation and 3D models that are geared towards research, education, diffusion and the preservation of heritage as important and unknown as is historical military heritage. Photogrammetry gives us the opportunity to bring to light the Ali Atar’s sword, one of the most relevant artistic manifestations belonging to the Nasri armament (Fig. 1, Table 1). The multi-view close-range photogrammetry is key to virtualise this jewel and also to contribute to the democratisation of the museum through the web dissemination of its content in a personalized way.Materials such as metals and precious stones, and gold techniques present in the Andalusian weapon required a particular photogrammetric data acquisition using a light booth and polarizing filter (Fig. 10), as suggested for the latter by (Guidi, Gonizzi, & Micoli, 2014). This setup brought a substantial improvement when dealing with highly reflective materials such as the metallic blade of Ali Atar's jineta sword. The use of the polarising filter attenuated the light that affects and reflects in the piece, benefiting both data acquisition and processing to deliver 3D models. We offered some results ready to safeguard, preserve and disseminate the jineta sword as a high-quality 3D model (Fig. 13), with submillimetre precision from which to obtain all the necessary metric deliverables. From the dense point cloud, two meshes were delivered: i) a homogeneous high resolution mesh keeping all the original features for archiving, conservation and research, and ii) a medium resolution mesh for web-based visualisation and dissemination. The aim was to achieve a detailed geometric documentation as well as complete and accurate 3D models (Fig. 29) for web repositories (https://skfb.ly/ZzzA), orthoimages (Figs. 30 and 31) that allow us to plot from CAD programs all the ornamental and decorative information of the piece (Figs. 32 and 33). In addition, we present some results related to monitoring and evaluation of changes in the state of conservation of the piece (Figs. 34, 35 and 36), extending the survey to preventive conservation studies.This research proves the value of geometric documentation techniques for the democratisation of museums. It contributes to improving the research processes, opening a new line of study. From this point we can rebuild the past through the virtuality, being able to mark and confirm historical hypotheses. These techniques offer the chance to give value to relevant and singular pieces in and out of museums. Both heritage and virtual archaeology are fundamental pillars to delve into the future of education and knowledge. | es_ES |
dc.description.abstract | [ES] Ali Atar, alcaide de Loja y señor de Zagra, nació hacia el año 1393. Fue uno de los principales jefes militares del periodo nazarí y llegó a emparentar con la Casa Real Granadina al casar a su hija Moraima con el mismo Boabdil, último Rey de Granada. Falleció en la batalla de Lucena en 1483, donde se le arrebató una de las magníficas espadas jinetas de manufactura andalusí conservada y localizada en los fondos del Museo del Ejército de Toledo (MUSEJE). Un recurso tan valioso como es el patrimonio cultural ya no se conforma con una conservación física; debe complementarse de una preservación digital exhaustiva en todas sus formas, siendo básico y necesario para su adecuada salvaguarda. Este artículo se centra en la digitalización tridimensional (3D) a partir de la fotogrametría digital y el modelado 3D de esta pieza de armamento histórico militar. Apoyándonos en la fotogrametría y en las tecnologías de la información y la comunicación (TIC), vamos a obtener una documentación geométrica de precisión y unos modelos 3D orientados a la investigación, educación, difusión y preservación de un patrimonio tan importante y desconocido como es el patrimonio histórico militar. Esta investigación demuestra la importancia de las técnicas de documentación geométrica para la democratización de los museos. Contribuye a mejorar los procesos de investigación, abriendo una nueva línea de estudio, a partir de la cual, podemos reconstruir el pasado a través de la virtualidad, pudiendo así marcar y confirmar hipótesis históricas. Estas técnicas ofrecen la posibilidad de poner en valor piezas relevantes y singulares dentro y fuera de los museos. Lo más destacado: Se adapta la fotogrametría multi-imagen de objeto cercano al proceso de documentación de una espada de manufactura andalusí del s. XV. Se describe un flujo de trabajo optimizado para documentar un objeto complejo: espada histórico-nazaríre cubierta de metales y materiales preciosos. La digitalización 3D puede contribuira la democratización de los museos gracias a la diseminación web de su contenido de una manera personalizada. | es_ES |
