“…However, the objective of our study was to evaluate the performance of the technique on site. The results can be considered complementary to other chemical characterization studies of pigments previously conducted on related sites (Roldán et al, 2010) as well as to earlier integral documentation work using 2D and 3D digital techniques (Domingo et al, 2013).…”

ABSTRACT:A case study to evaluate the use of microfading spectrometry (MFS) for the study of colored systems found in prehistoric rock art paintings was conducted in the Cova Remígia rock-shelter, Castellón (Spain). This rock shelter is part of the rock art sites of the Mediterranean basin on the Iberian Peninsula included in UNESCO's World Heritage List. Some of the paintings belonging to this group are exposed to environmental factors including natural daylight, wind and rain, depending on the time of the day and the season of the year. Therefore, their preservation is a major concern to stakeholders and researchers responsible for protecting and studying these prehistoric paintings. The experimental work in Cova Remigia focused on measuring the reflectance curves (400-700 nm) and determining the photostability of various areas containing red and black pigments on the rock art paintings. The preliminary results indicate that MFS is a suitable technique for studying the response to light of rock/pigment systems found in rock art sites. The advantages and limitations of the technique are discussed.

“…Por el contrario, un molde, o cualquier otra técnica de contacto directo con la obra puede ejercer cierta degradación con la transferencia de humedad, partículas contaminantes y desgaste (Rogerio, 2007). Por lo tanto, estas nuevas técnicas documentan de modo similar a los vaciados, frottage o calcos tradicionales, pero siendo respetuosos con la integridad de la obra y a la vez, siguen generando copias métricas exactas (Domingo et al, 2013).…”

Resumen:Este artículo se centra en el estudio del cubrimiento del corredor del Dolmen de Cubillejo de Lara, Burgos (España). A través de técnicas de computarización, se ha contribuido a despejar dudas en cuanto a lo que es y no es posible respecto a su arquitectura original. Durante el proceso, se recuperó cierta información perdida relativa a los petroglifos situados en dicho corredor, la cual ha sido determinante para comprender la solución constructiva de esta estructura en el pasado. Dicha comprensión, se ha alcanzado como fruto de un trabajo interdisciplinar dónde el diagnóstico del estado de conservación del material pétreo ha jugado un papel fundamental, auxiliado de técnicas como la ortofotogrametría, el modelado tridimensional (3D) y el sistema de información geográfica (SIG), para conocer cómo los procesos de degradación han conformado el estado actual del corredor dentro del conjunto dolménico y de este modo, poder reconstruir a partir de la información precisa que disponemos en la actualidad, su posible estado original. El resultado ha sido contrastado con los ejemplos dolménicos paralelos que se encuentran por la zona, gracias a lo cual, se ha verificado la utilidad de las reconstrucciones virtuales para corroborar o desmentir hipótesis que previamente se habían afirmado repetidamente durante décadas sin una evidencia que las respaldase.Palabras clave: arqueología virtual, fotogrametría, reconstrucción 3D, SIG, megalistismo. Abstract:This article focuses on the study of the ceiling of the corridor of the Dolmen of Cubillejo de Lara, Burgos, Spain. The process of computerisation has contributed to a better comprehension of what may or may not have been possible for its original architecture. During the study, previously lost information regarding petroglyphs within the corridor was recovered, which has been very important in understanding the structural solution of this structure in the past. This has been the fruit of interdisciplinary work, where the diagnosis of the state of the stone has played a fundamental role, assisted by techniques such as orthophotogrammetry, three-dimensional (3D) modelling and geographic information system (GIS), to recognise how the process of degradation has shaped the current condition of the corridor as part of the construction, in such a way as to be capable to reconstruct its possible original form through its current state. The result has been contrasted with other concurrent dolmens existent in the area, which has confirmed the validity of virtual reconstructions to confront hypotheses sustained for decades without further evidence to back them.Key words: virtual archaeology, photogrammetry, 3D reconstruction, GIS, megalithism. IntroducciónEn un momento tan temprano como el siglo XX, el conservador de monumentos austriaco Alois Riegl (1903), de forma similar a las actuales recomendaciones vigentes en materia de conservación de patrimonio (De Naeyer et al., 2000), sostenía que no es posible reconstruir monumentos directamente piedra sobre piedra. Esto según sus ide...

“…3. These images were used to deliver both high resolution and high accuracy 3D point clouds from which motifs would be recreated as accurately and realistically as possible, as recommended by Domingo et al (2013), to facilitate the understanding of the rock art with the rock surface. An overall root mean square error (RMSE) of 2 mm was achieved in the registration of the four scans in 3DVEM -Register.…”

ABSTRACT:Nowadays it is possible to measure accurately dense point clouds either with aerial/terrestrial laser scanning systems or with imagebased solutions (namely based on photogrammetric computer vision algorithms such as structure-from-motion (SfM)), from which highly detailed 3D models can be achieved. Besides, direct tools in the form of simple devices such as rulers, compass and plumblines are usually required in simple metric surveys, as well as high-end surveying and geodetic instruments such as robotized imagebased total stations and GNSS (probably to a lesser degree but still required) to set the archaeological/architectural recording project in a global reference frame. With all this gamut of image-based and range-based sensors and datasets (in the form of coordinates, point clouds or 3D models), in different coordinate systems (most of the times local for each device), lack of uniform scale, orientation and levelling, the fusion of data tends to be cumbersome. This paper presents an efficient way to fuse and merge different datasets in the form of point clouds/3D models and geodetic/UTM coordinates. The new developed 3DVEM -Register GEO software is able to handle datasets coming from both direct and indirect methods in order to provide unified and precise deliverables.
