In particular, it aims to draw attention to a possible measurement and data processing procedure allowing the rapid collection and post-processing of data in order to extract classical architectural products such as sections and profiles, and to build complete, accurate 3D models. The need is to structure a multiple data source procedure within a five-year project (still in progress) to survey and model the main spire of Milan Cathedral three-dimensionally. The spire is a very complex object and, for this reason, provides a really useful, challenging field test for new 3D survey technologies and, in particular, for integrating a variety of modelling methodologies. The paper describes survey workflow and processing steps, focusing on problems and justifying key choices.

Generation of a spatial information system for architecture with laserscanning data / Luigi Fregonese (2009)  

Public contenu dans ISPRS Workshop Laserscanning'09, Paris, France, September 1-2, 2009 / Frédéric Bretar (2009)   Titre : Generation of a spatial information system for architecture with laserscanning data Type de document : Article/Communication Auteurs : Luigi Fregonese, Auteur ; Marco Scaioni, Auteur ; Laura Taffurelli, Auteur Editeur : International Society for Photogrammetry and Remote Sensing ISPRS Année de publication : 2009 Collection : International Archives of Photogrammetry, Remote Sensing and Spatial Information Sciences, ISSN 1682-1750 num. 38-3/W8 Conférence : ISPRS 2009, Workshop LaserScanning 01/09/2009 02/09/2009 Paris France OA Archives proceedings Importance : pp 87 - 92 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] architecture [Termes IGN] base de données localisées 3D [Termes IGN] modélisation 3D [Termes IGN] patrimoine culturel [Termes IGN] surveillance d'ouvrage [Termes IGN] Venise Résumé : (Auteur) In architectural and cultural heritage documentation, laser scanning technology today offers several opportunities to approach the object to study and to extract manifold information levels from it. These account for point-clouds, 3-D models, and other data about the state of conservation. Georeferenced point-clouds can be adopted as the spatial framework of a Space Information System for Architecture, integrating all spatial information acquired by TLS, photogrammetry, geodetic surveying and direct survey, but also from other investigation techniques (e.g. GPR, thermal cameras, etc.). Such information system allows to make assessments that are important for the classification of structural elements or for the determination of the state of decay or preservation of each architectural element. With reference to the survey of two wooden domes of San Marco Basilica in Venice (Italy), the completion of the 3-D model of their complex structure is presented here through the description of its main stages, i.e. data acquisition, registration and modelling. The final 3-D model is then assumed as a 3-D database which clarifies the shape, the composition, the state of conservation and the structural function of the wooden beams of the domes.
