Main feature of photogrammetry is the measurements which are made on photographic projection of the objects instead of making them directly on the object. Because of its indirect measurement feature, it has various application areas. Widespread use of photogrammetry increases the importance of calibration of cameras in the frame of photogrammetric principles. In this study, images of test fields shot by Nikon Coolpix 950 digital camera were analyzed using Bundle adjustment method while images of test fields obtained from portable roentgen device were analyzed using Direct linear transformation (DLT) method and all the results obtained from different methods were compared.


Key words: X-ray photogrammetry, calibration, digital photogrammetry, direct linear transformation.
