Advanced 3D recording techniques and reality-based modeling of multi-scale for the digital preservation of Cultural Heritage and Sites

Abstract eng:
The paper describes reading criteria for the interpretation/documentation and the procedures followed by integrated digital survey for important buildings in Rome and Trento as a case study of the research on the integration of new technologies to obtain 3D multi-scale representation architectures. Moreover affords an overview of the actual optical 3D measurements sensors and techniques used for surveying, mapping, digital documentation and 3D modeling applications in the cultural heritage field. Today new opportunities for an integrated management of data are given by multi-resolution models, that can be employed for different scale of representation. The study from the methodological point of view has made use of the identification of levels of study differentiated, each of which is capable of identifying categories. Detected by the various categories it was possible to extract a complex set of information in terms of structural, formal and functional. With the integration of all the techniques used in this paper, a 3D model with a relevant rich database of information was obtained as an interface to share and visualize information with web-based tools. It ensures today a proper preservation of the monuments, and an understanding of their evolution within the urban environment for the future, because of the various economic incentives.
