Using photogrammetric data for establish finite element model of masonry structures

ABSTRACT There are various methods of documentation the historical and cultural heritage. Besides photographs, sketch, perspectives, video records etc photogrammetry is also a method for collecting the data. Photogrammetry became a widespread method in architecture, with developing computer industry. In comparison with the other documentation methods, photogrammetry is faster and more precise. Metric cameras and laser scanning are used as measurement techniques in photogrammetric method. Data collected from both of the techniques can be used in architecture. In this way, time and effort is reduced while making as built drawings. Structure's 3D model should be formed for determining the existing situation of the building. With the structural analysis of the model existing situation of building is determined. Various analyses methods are used for these processes. The most widespread one is finite element method. The finite element model of the structure can be evaluated by different ways. In this thesis, the photogrammetric data analysis model is studied. Several methods are studied and the application is done on the historical Eğrikemer. Without depending a specific program, the finite element models are studied by using photogrammetric datas. 3D node points model and 3D solid model are evaluated. Participated projects of architecture and photogrammetry disciplines can make the historical and cultural heritage documentation faster and more precise. With developing computer technology, by taking advantage of photogrammetric data acquisition, finite element model of masonry buildings can be evaluated.
