Knowledge and safeguarding of cultural heritage. new technologies for survey and restoration: Innovative methods and non-destructive investigation

Abstract

The new technologies related to survey and restoration offer significant applicative potentiality for the documentation and valorisation of cultural heritage, both in terms of data acquisition and for all representation, conservation and dissemination stages. The current methodologies and tools offered very promising opportunities for Cultural Heritage, either for the surveying process or for representation purposes, for objects of architectural, artistic and archaeological interest. This paper highlights how various illustration techniques can be used to create original visual narratives of existing urban realities and future ideas for the development of the city. The paper focuses on the case study of Villa Rivaldi in Rome; after a short discussion of the main questions connected to the field of urban representation, it illustrates the main techniques adopted and related products, with specific interest for photogrammetry and laser scanning. In particular, it shows an application of high resolution laser scanning survey, with photogrammetry data integration, in order to create a digital 3D model of a portion of the facades of Villa Rivaldi.
