Recovering old stereoscopic negatives and producing digital 3D models of former appearances of historic buildings
(ISPRS (International Society for Photogrammetry and Remote Sensing), 2017-03)
[EN] Three-dimensional models with photographic textures have become a usual product for the study and dissemination of elements of heritage. The interest for cultural heritage also includes evolution along time; therefore, ...
Methodological keys for the acquisition and long-term use of photographic collections representing elements of Heritage
(Computer Applications and Quantitative Methods in Archeology (CAA), 2010-04)
[EN] Photographic pictures contain high-resolution information about the elements of
Heritage and they can be obtained at a low cost. Besides, they can be used metrically with different degrees of accuracy: from the ...
Model of sources: a proposal for the hierarchy, merging strategy and representation of the information sources in virtual models of historical buildings
(Computer Applications and Quantitative Methods in Archeology (CAA), 2010-04)
[EN] Virtual models show an image of the historical buildings for a specific moment in
time and with a definite level of detail. Many information sources are normally
required to build up a virtual model, some common ...
Virtual Reconstruction of the Ancient State of a Ruined Church
(Springer Berlin Heidelberg, 2012-11)
[EN] Three dimensional virtual models can represent both the existing and the already destroyed architectural heritage. This project deals with the 3D reconstruction and representation of the church of San Prudencio's ...
Evaluation of the conventional surveying equipment applied to deformation analysis of heritage buildings. A case study: the bell tower of Santa María la Blanca church in Agoncillo (La Rioja, Spain)
(International Federation of Surveyors (FIG), 2008-05)
[EN] A typical feature of heritage buildings is their fragility that is displayed by means of several pathologies such as wall sloping or cracks. Although there are some model projects on monitoring, they are usually ...
3D line drawing from point clouds using chromatic stereo and shading
(Virtual Systems and Multimedia – VSMM2008, 2008-10)
[EN] Terrestrial laser scanners (TLS) have become a common tool in geometric documentation of heritage. As output, they can produce point clouds along with thematic information such as reflectance or photographic texture. ...
Radiometric balance of photographic textures in virtual models and point clouds of heritage elements
(Laboratorio de Documentación Geométrica del Patrimonio (LDGP), 2007-09)
[EN] When facing the representation of heritage elements, a wide range of graphical products are at our disposal which incorporate photographic texture, such
as ortophotographs, virtual models or point clouds. Photographic ...
Time transcendence, metadata and future utilization in 3D models of point clouds for heritage elements
(Ausonius éditions, 2007-11)
[EN] Heritage is not static, on the contrary, it is subject to continuous modifications and transformations which, at worst, go as far as to their complete disappearance; for this reason, information referring to heritage ...
Problems when generating virtual models representing real objects: Hondarribia walls
(2006)
[EN] This report shows an example of virtual modelling applied to a heritage construction, the walls of the city of Hondarribia (Gipuzkoa, Spain). Therefore, it is not a model recreating a building upon hypothetical data ...
3D Modelling in the registration and restoration of a megalithic tomb
(ISPRS (International Society for Photogrammetry and Remote Sensing), 2017-05)
[EN] This article aims at showing some potential applications of geomatics to works in which both excavation and restoration are carried out simultaneously, so that the three-dimensional layout of the monument undergoes ...
