Preservation of Architectural Heritage Through 3D Digitization

Abstract

Continuity and relation to the past are inherent in human nature.The remains of the past constitute culture and cultural heritage. Preservation and dissemination of cultural heritage appear to be, nowadays, a universal priority. Historic/architectural monuments are among the most significant categories of cultural heritage and their 3D digitization appears to be a chief way towards that direction. 3D digitization of architectural heritage is a very specific problem in the digitization domain. Since size, budget and applicability are some of the most important factors in choosing an appropriate digitization method, and since there is not an all-in-one solution in digitization, this problem cannot be always addressed by using one technique. In this paper we review methods that are available for 3D digitization of architectural heritage and we present two case studies of real-world digitization projects involving monuments and urban areas.

Application of three-dimensional technologies in restoration of architectural decor elements

“…At present, restoration of historical building facades more often than ever uses innovative 3D scanning and printing techniques, which produce an exact digital threedimensional copy of an object within minutes. Application of the three-dimensional scanning technology produces high accuracy of digital copies of the elements scanned [1][2][3][4][5][6], enables repeated reproduction of undistorted architectural items and parts, and makes it possible to produce shallow (lightweight) and solid elements of exterior and interior decor…”
