Digital Modelling and Accuracy Verification of a Complex Architectural Object Based on Photogrammetric Reconstruction

Data concerning heritage buildings are necessary for all kinds of building surveying and design. This paper presents a method creating precise model historical architectural landscape object with complex geometry. Photogrammetric techniques were used, combining terrestrial imaging photographs taken using UAVs. In large-scale objects, it is to divide the reconstruction into smaller parts adopt an iterative approach based on gradual completion missing fragments, especially those resulting from occlusions. The developed via was compared geometrically reliable data (LAS point clouds) available in public domain. degree accuracy achieved can be used conservation, example, construction cost estimates. Despite extensive research photogrammetric their applicability reconstructing cultural sites, results obtained have not yet been by other researchers LAS clouds information system land cover (ISOK).
