3D Digital Reconstruction of Heritage Buildings by Using Old 2d Plans

Abstract

The paper describes a method of finding the optimal solution to use amateur digital cameras with lenses that are not designed for measuring purposes, including those installed on mobile phones, in the process of digitizing existing documents of architectural and other material heritage. By combining the data contained in the old 2D plans as well as the data from other preserved technical drawings with the data measured directly in the field, high-quality geometric data is obtained. In this way, a reliable basis is obtained for the creation of adequate 3D models of the considered cultural heritage buildings. Thanks to this, the versatile application of digital cameras in the preservation of cultural and historical heritage is enabled, through the high-quality and fast creation of permanent records for future generations. This creates predispositions for the effective management of digital spatial data within cultural heritage while ensuring a basis for their safe use. Through the necessary introduction of norms and specifications in the process of geospatial data collection, an important contribution is made to raising awareness of the importance of cultural and historical heritage.
