“…Their research concluded that traditional survey workflows were inefficient and that IMMS might provide a solution. Several other papers have been presented on the ZEB1, describing the system as a solution for low accuracy applications (Bosse et al, 2012, Zlot et al, 2013. Similar to the Viametris, findings have been reported for several other trolley based systems (Viametris, 2007, NavVis, 2013, Trimble, 2012.…”

“…Thomson et al (Thomson et al, 2013) concluded that despite the enormous time savings, these systems do not perform adequately for high accuracy applications. Bosse et al (Bosse et al, 2012) and Zlot et al (Zlot et al, 2013) confirm that hand held mobile devices like the ZEB1 are only fit for low accuracy applications. Trolley based systems from Viametris, Navvis or Trimble show better results, yet lack the accuracy to provide LOA30 (Viametris, 2007, NavVis, 2013, Trimble, 2012.…”

ABSTRACT:With the increasing popularity of as-built building models for the architectural, engineering and construction (AEC) industry, the demand for highly accurate and dense point cloud data is rising. The current data acquisition methods are labour intensive and time consuming. In order to compete with indoor mobile mapping systems (IMMS), surveyors are now opting to use terrestrial laser scanning as a standalone solution. However, there is uncertainty about the accuracy of this approach. The emphasis of this paper is to determine the scope for which terrestrial laser scanners can be used without additional control. Multiple real life test cases are evaluated in order to identify the boundaries of this technique. Furthermore, this research presents a mathematical prediction model that provides an indication of the data accuracy given the project dimensions. This will enable surveyors to make informed discussions about the employability of terrestrial laser scanning without additional control in mid to large-scale projects.

“…Different technologies exists nowadays to deal with the 3D reconstruction of assets, mainly stereophotogrammetry, laser scanning or structured lightbased techniques, though other approaches have been investigated (Sansoni, Trebeschi, & Docchio, 2009;Granero-Montagud et al, 2013;Groves, Portalés, & Ribes-Gómez, 2014;Zhang et al, 2012;Zlot et al, 2013). The visual appearance or photometric properties is also of utmost importance.…”

Abstract:3D virtual reconstruction of cultural heritage is a useful tool to reach many goals: the accurate documentation of our tangible cultural legacy, the determination of mechanical alteration on the assets, or the mere shape acquisition prior to restoration and/or reconstruction works, etc. Among these goals, when planning and managing tourism enhancement of heritage sites, it demands setting up specific instruments and tools to guarantee both, the site conservation and the visitors' satisfaction. Archaeological sites are physical witnesses of the past and an open window to research works and scientific discoveries, but usually, the major structures do no exist nowadays, and the general public takes long time and many efforts to elaborate a mental reconstruction of the volumetry and appearance from these remains. This mental reconstruction is essential to build up a storyline that communicates efficiently the archaeological and historic knowledge and awares the public about its conservation. To develop this process of awareness about conservation, heritage interpretation starts with the mental inmersion of the visitors in the archaeological site, what 3D reconstruction definitely helps to achieve. Different technologies exist nowadays for the 3D reconstruction of assets, but when dealing with archaeological sites, the data acquisition requires alternative approaches to be used, as most part of the assets do not exist nowadays. In this work, we will deal with the virtual reconstruction and visualisation of the archaeological site Castellet de Bernabé by following a mixed approach (surveying techniques and archaeological research). We further give a methodology to process and merge the real and virtual data in order to create augmented views of the site.Key words: virtual archaeology, digital archaeology, cultural heritage interpretation, 3D reconstruction, tourism enhancement Resumen:La reconstrucción virtual 3D del patrimonio cultural es una herramienta muy útil para alcanzar varios objetivos: el registro preciso de nuestro legado cultural tangible, determinar alteraciones físicas en los bienes o simplemente registrar las formas y estructuras previamente a trabajos de restauración y/o reconstrucción, etc. Entre estos objetivos, cuando se planifica y gestiona la puesta en valor turístico de sitios patrimonio, es necesario establecer instrumentos y herramientas para garantizar la conservación del patrimonio, a la vez que la satisfacción del visitante. Los yacimientos arqueológicos son testimonios del pasado y son una ventana abierta a los trabajos de investigación y hallazgos científicos, pero a menudo las estructuras principals ya no existen y el público general necesita mucho tiempo y esfuerzo para elaborar una reconstrucción mental de la volumetría y apariencia a partir de las ruinas. Esta reconstrucción mental es esencial para construir una línea argumental que comunique de forma eficiente el conocimiento arqueológico e histórico, y así se conciencie al público sobre su conservación. Para desarrollar este...

“…Macroscopic analysis of degradations affecting the surfaces has been carried out through high definition photographic survey, an essential support to draw up a comprehensive picture of the state of conservation. The integrated methodology leaded to a geometric model of spatial coordinates hierarchically-defined and with a single reference system (Zlota et al, 2014). DEM from instrument source have been used as the basis for editing CAD representations of all the architectural elements and the sectionplans.…”

ABSTRACT:Documentation of cultural assets through improved acquisition processes for advanced 3D modelling is one of the main challenges to be faced in order to address, through digital representation, advanced analysis on shape, appearance and conservation condition of cultural heritage. 3D modelling can originate new avenues in the way tangible cultural heritage is studied, visualized, curated, displayed and monitored, improving key features such as analysis and visualization of material degradation and state of conservation. An applied research focused on the analysis of surface specifications and material properties by means of 3D laser scanner survey has been developed within the project of Digital Preservation of FAUUSP building, Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo, Brazil. The integrated 3D survey has been performed by the DIAPReM Center of the Department of Architecture of the University of Ferrara in cooperation with the FAUUSP. The 3D survey has allowed the realization of a point cloud model of the external surfaces, as the basis to investigate in detail the formal characteristics, geometric textures and surface features. The digital geometric model was also the basis for processing the intensity values acquired by laser scanning instrument; this method of analysis was an essential integration to the macroscopic investigations in order to manage additional information related to surface characteristics displayable on the point cloud.
