[ESP]
Este estudio analiza y compara las técnicas de fotogrametría y escaneo láser 3D en el modelado 3D de objetos patrimoniales escultóricos, evaluando su facilidad de uso, eficiencia, calidad de los modelos generados y limitaciones. Se lleva a cabo el contraste mediante el modelado 3D, con ambas técnicas, del Ara de la Domus do Mitreo en Lugo (España). Los resultados demuestran que ambas técnicas son precisas y fiables, con la fotogrametría destacándose por su accesibilidad y flexibilidad en costos, y el escaneo láser por su alta precisión e inmediatez. Además, se contribuye al estudio de la viabilidad de utilización de estas técnicas en las actividades cotidianas de museos y otras instituciones culturales aun teniendo en cuenta que en dichas instituciones no nos encontremos con personal especializado en la digitalización o diseño gráfico; proporcionando a los gestores culturales información útil para tomar decisiones informadas sobre la implementación de estas tecnologías, mejorando la preservación y difusión del patrimonio cultural de manera sostenible y efectiva.
[ENG] This study analyzes and compares photogrammetry and 3D laser scanning techniques in the 3D modelling of sculptural heritage objects, evaluating their ease of use, efficiency, quality of generated models, and limitations. The comparison is carried out by modelling the Ara of the Domus do Mitreo in Lugo (Spain) using both techniques. The results show that both techniques are accurate and reliable, with photogrammetry standing out for its accessibility and cost flexibility, and laser scanning for its high precision and immediacy. Furthermore, this study contributes to the examination of the feasibility of utilizing these techniques in the daily activities of museums and other cultural institutions, even considering the potential absence of personnel specialized in digitization or graphic design. It provides cultural managers with useful information to make informed decisions about the implementation of these technologies, thereby improving the preservation and dissemination of cultural heritage in a sustainable and effective manner.
