La documentazione del patrimonio culturale perduto mediante fotogrammetria e intelligenza artifi ciale

Abstract

This research aims to give an analysis and assessment through the extraction of metricinformation from historical images and to experiment with its potentialities in the heritage fi eldwith the aim of valorising historical iconographical documentation. In particular the paperdeals with photogrammetry applied to historical images. A classifi cation and a state of the artof historical archives material considering their possible use in metric documentation and thussuitable for photogrammetry is performed. A photogrammetric workfl ow is proposed to processhistorical images and the maximum metric quality level reachable by the photogrammetricprocessing is investigated. Two case studies in Paris were chosen: the UNESCO HeritageTour Saint Jacques and the pavilions of Les Halles of the architect Victor Baltard. The twostudies represent different situations of heritage because the tower was transformed over timebut still exists and the pavilions were destroyed in 1971. Thus, it is possible to compare thedifferent results obtained from the implementation of the workfl ow to the two case studies.
