Research on the Conservation of Historical Buildings Based on Digital 3D Reconstruction

Abstract

As a cultural carrier, historical buildings embody the humanistic atmosphere of different periods and regions, and contain a profound cultural heritage, being the crystallization of the wisdom of the Chinese nation for thousands of years. At present, when repairing and protecting existing historic buildings, without complete construction information to maintain the "authenticity" they contain, any conservation action may cause irreversible secondary damage, making the restoration of historic buildings particularly difficult. Compared to traditional conservation methods, digital conservation has the advantages of efficiency, accuracy, three-dimensionality, realistic reproduction and preventable simulation, and the application of digital technology can improve the overall level of conservation of historic buildings. Therefore, for the better conservation of historic buildings, this paper summarises a feasible and realistic approach to the digital conservation of historical buildings by collecting information on Building A, using software to numerically simulate the 3D model for virtual restoration, and using digital technology for virtual restoration research.
