Terrestrial photogrammetry and application to modeling architectural objects

Abstract

In this paper terrestrial photogrammetry is analyzed and its applications in architecture presented. Photogrammetry is a technique of representing and measuring 3D objects using data stored on 2D photographs and it has many advantages over traditional methods. We give theoretical background for the methods used in creating 3D models from photographs and then, using the appropriate software, we apply these methods to create 3D models of architectural objects. Using the described photogrammetric methods we constructed detailed 3D models of over 100 sacral objects in Vojvodina built from 18th until the first half of the 20th century. Many of these objects were seriously damaged, some in a critical condition and it was the last moment to record their present state.U ovom radu analizirana je terestrijalna fotogrametrija i njene primene u domenu arhitekture. Fotogrametrija je metoda kojom se predstavljaju i dimenzioniraju 3D objekti koristeci podatke sa 2D fotografija i ona ima mnoge prednosti u odnosu na tradicionalne postupke. Date su teorijske osnove metoda koji su korisceni u kreiranju 3D modela na osnovu fotografija a onda, koristeci odgovarajuci softver, ti metodi su primenjeni na kreiranje 3D modela arhitektonskih objekata. Koristeci opisane fotogrametrijske metode konstruisali smo detaljne 3D modele preko 100 sakralnih objekata u Vojvodini izgradjenih od 18. do prve polovine 20. Veka. Mnogi od tih objekata su bili veoma osteceni, neki od njih u kriticnom stanju, i ovo je bio poslednji trenutak da se zabelezi njihovo sadasnje stanje.
