Modeling of historical bridges using photogrammetry and virtual reality
Seker, Dursun Z. ... [et al.]
Anatolian civilizations left their marks on the development of science, culture and art and as a result, many scientists, engineers, artists and architects were born. No doubt the most important of these was Architect Sinan. He was an architect of high capability who has left his impact on the Golden Age of Architecture during the Ottoman Empire. After he was promoted to the position of Head Imperial Architect in 1558, he retained his position for 50 years and built more than 350. Among these small or large monuments or structures, water arches, bridges and mosques have the majorities. In this study Kapuağası Bridge, which is one of the built of the Architect Sinan, has been selected as study object. This Bridge was built on Harami Stream in the 16th Century which is the closest bridge built by Architect Sinan to Istanbul city centre. It is approximately 75 meters in length and 6 meters in width with three arches. After the construction of a new bridge on the Edirne-Istanbul Highway, Kapuağası Bridge has become out of usage. The aim of the study is to digitally photograph the historical bridge by means of the terrestrial photogrametric techniques. 2D and 3D coordinates of each single stones of the bridge were obtained from digital images. These coordinates were used to prepare sketches of the bridge in different scales. Those data also used to forming virtual model of the bridge. Using this model a short video that is in avii format was prepared. This model and video indicates the capability of these techniques in the preserving and documentation of cultural heritage, which is very difficult and time consuming with the conventional methods.
