“…The scanner collects a ' point cloud ' , and was assembled at four locations inside the auditorium (the stage, stalls, circle and balcony). The process followed was similar to that reported previously in the literature ( Barber et al , 2006 ;Arayici, 2007 ), where a range of techniques have been used to utilise the resultant data set within architectural modelling.…”

Richard Laingholds qualifi cations in Surveying and History, and completed a PhD in value assessment at RGU. Since 1999, he has led and participated in a number of research commissions, including ' Streetscapes ' , ' Greenspace ' and ' Urban Connections. In addition, he has recently led research and development projects for the Department of Health, the ESF and Interreg ERDF, as well as participating as a co-investigator on work supported by the ESRC. He represents the RICS on the European Construction Technology Platform, with a particular emphasis on energy effi ciency in buildings. Jonathan Scottcompleted an HND in Architectural Technology in 1992, followed by a degree in Architectural Technology, graduating in 1998 with a fi rst-class award. Supported by an EPSRC studentship, Scott undertook a PhD, completed in 2004, in the fi eld of environmental design, creating a decision-making tool for the selection of detached homes. Except for a short stint in industry, he has worked in research and teaching, developing his interests in the areas of environmental design, energy monitoring, life-cycle analysis, social and occupancy evaluation. In addition, he is also interested in CAD, surveying technologies and historic conservation.

In particular, it explores how such technology can be used as a complement to both traditional measurement and historic records, as well as in the 3D surface modelling of heritage detail. The article uses examples from cinema buildings of the twentieth century, which arguably embody both an important physical record of society and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets. The work provides an overview of visualisation techniques that are appropriate to the subject, and provides a case study taken from the city of Aberdeen. In particular, attention is drawn towards the manner in which large and physically complicated structures can be recorded rapidly, to provide a permanent record of dimensions and building form. Furthermore, the data set produced through use of a 3D scanner can be readily translated for incorporation within architectural models such as a 3D surface mesh. The article concludes that emerging technologies will facilitate the rapid collection of highly accurate information pertaining to the still intact physical structure, where still in place, but that such data must be related directly to wider contextual information so that informed plans can be formulated for future developments, including conservation strategies.

“…With the aim of documenting the surface geometry of the scanned elements, a set of high resolutions measures, of at least one point every 2 mm [3], was required. The information generated was stored as scalar values as a 3D cloud of points, which would later be converted into 2D raster databases.…”

“…In historic stone buildings, many different types of damage can occur including: loss of stone material, discoloration, deposits, detachment, fissures, deformation, and damage from previous intervention [1]. Detection of material degradation in historic buildings with traditional methods, such as manual mapping or simple eye examination by an expert [2], are considered time-consuming [3] and laborious procedures, so TLS (Terrestrial Laser Scanner) technology and image processing methodologies are being developed, allowing for the detection of pathologies [4,5], their evolution [6], identification of deformations [7], changes in material [8], and stone façade documentation [9][10][11].…”

This article presents a methodology to process information from a Terrestrial Laser Scanner (TLS) from three dimensions (3D) to two dimensions (2D), and to two dimensions with a color value (2.5D), as a tool to document and analyze heritage buildings. Principally focused on the loss of material in stone, this study aims at creating an evaluation method for loss control, taking into account the state of conservation of a building in terms of restoration, from studying the pathologies, to their identification and delimitation. A case study on the Cathedral of the Seu Vella de Lleida was completed, examining the details of the stone surfaces. This cathedral was affected by military use, periods of abandonment, and periodic restorations.

“…Laser-based systems are common for architectural conservation Barber et al (2006) and offer a wide variety of technologies (timeof-flight, phase modulation, optical triangulation, etc.) to adapt to the specific task (e.g., surveying large environments or digitizing small artefacts) and accuracy needed.…”

ABSTRACT:In this paper we present our novel approach for acquiring and managing digital models of archaeological sites, and the visualization techniques used to showcase them. In particular, we will demonstrate two technologies: our robotic system for digitization of archaeological sites (DigiRo) result of over three years of efforts by a group of cultural heritage experts, computer scientists and roboticists, and our cloud-based archaeological information system (ARIS). Finally we describe the viewers we developed to inspect and navigate the 3D models: a viewer for the web (ROVINA Web Viewer) and an immersive viewer for Virtual Reality (ROVINA VR Viewer).
