Detailed documentation and 3D model creation of Dalal Bridge using terrestrial photogrammetry in Zakhu, northern Iraqi Kurdistan
Original language description
In 2008, the Dalal bridge was documented by terrestrial digital photogrammetry using a calibrated digital camera Canon 20D and necessary geodetic measurement. Photomodeler ver.6 and AutoCAD software were used for creating a 3D model. About 120 digital images were originally taken, including vaults. 69 images and about 100 control points were used as a background for a 3D model in vector format. After this, a rendered model from original photos was created. Achieved accuracy of control points was approximately 1-2cm, in the case of processed object points about 2-5cm. Both sides of the bridge are approximately flat, but for arches it was necessary to use a special process - particular arch rings represented a special case where it was necessary to divide the arch surface to more flat surfaces which substituted the arch. The final model is now under construction and after finishing it will be used for future restoration of the bridge, which is now only under planning.
