Application of digital techniques in monument preservation / Xavier Brunetaud in European journal of environmental and civil engineering, Vol. 16 N° 5 (Mai 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 5 (Mai 2012) . - pp. 543-556 Titre : Application of digital techniques in monument preservation Type de document : texte imprimé Auteurs : Xavier Brunetaud, Auteur ; Livio De Luca, Auteur ; Sarah Janvier-Badosa, Auteur Année de publication : 2012 Article en page(s) : pp. 543-556 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Conservation  3D  reconstruction  Monument  Mapping  of  deterioration  Stonework  dating Résumé : Health records for monuments are produced to provide a basis for scientific monitoring and planning of restoration work. The collected data (locations of deterioration, and architectural and historical archives) must be referenced in a single documentation platform to establish a detailed diagnosis of the state of degradation of the monument. This paper presents the application of digital techniques for production of a health record of a monument, applied to the castle of Chambord (Loire Valley, France). The first step is to provide a 3D digital reconstruction of the monument. This 3D modelling consists in constructing a finely refined and relevant graphic base to spatially reference all data acquired during the project. Topography is used to precisely locate the relative position of the main architectural components, while photogrammetry can set in detail each of these elements. The application of textures extracted from pictures on surfaces of the 3D model provides a realistic appearance. Additional data from a laser scanner can be included to detail complex forms or specific degraded areas for monitoring or documentation purpose. The state of deterioration of the structure is evaluated through a visual in situ survey. Dating and identification of rocks are determined by searching in the historical and architectural archives that are sometimes incomplete. Finally, the NUBES web-based platform is used to spatially associate data with the 3D model of the monument. This database underpins the health record of the castle of Chambord.

Comparison between photomodelling and laser scanning to create a 3D model for a digital health record / Xavier Brunetaud in European journal of environmental and civil engineering, Vol. 16 Supplément N° 1 (Juin 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 Supplément N° 1 (Juin 2012) . - pp. s48-s63 Titre : Comparison between photomodelling and laser scanning to create a 3D model for a digital health record Type de document : texte imprimé Auteurs : Xavier Brunetaud, Auteur ; Chiara Stefani, Auteur ; Sarah Janvier-Badosa, Auteur Année de publication : 2012 Article en page(s) : pp. s48-s63 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Photogrammetry  Laser  scanner  3D  modelling  Cultural  heritage Résumé : This work deals with the creation of a digital health record for the Castle of Chambord (Loire Valley, France) to establish a detailed diagnosis of the state of deterioration of the monument. This digital health record aims to provide a basis for scientific monitoring and planning of restoration work by referencing data (mapping of deterioration and architectural and historical archives) on a Web-based documentation platform. The starting point is building a 3D model of the monument. This 3D model must meet specific requirements for its subsequent use, including the ability to be unfolded in 2D with visual consistency. The method to be used for 3D acquisition depends on a balance between speed of execution, cost, and compatibility with respect to data organisation. This paper presents a comparative study between photomodelling and laser scanning. The different steps needed to build a reliable 3D model with both techniques are demonstrated along with a critique of the advantages and disadvantages of each.
