3D Modeling Techniques for the Restoration and Conservation of Historical Buildings

Summary/Abstract: In the restoration and conservation of historic buildings and monuments, for verification and repairs of any kind, accurate information on shape, size and architectural details are of utmost importance. The field of photogrammetry plays an important role in this process, through the possibilities of 3D modeling and representation of historical buildings and monuments. At present, there are a series of photogrammetric software with expertise in image processing algorithms, with digital photogrammetric techniques that establish the direction of development of the applied instruments. The process of photogrammetric modeling uses terrestrial and aerial images of the building attached to the solid model, obtaining a 3D realistic model. This is easily visualized, analyzed and modified by users, even in other fields, such as architecture or history. The advantage of the “multi-view 3D reconstruction technology” is the possibility to use images no matter the shooting distance, as long as each two images contain common points.
