Rapid progress in digital technology enables us to create three-dimensional models using digital images. Low
cost, time efficiency and accurate results of this method put to question if this technique can be an alternative to
conventional documentation techniques, which generally are 2D orthogonal drawings. Accurate and detailed
3D models of archaeological features have potential for many other purposes besides geometric documentation.
This study presents a recent image-based three-dimensional registration technique employed in 2013 at one of
the ancient city in Turkey, using “Structure from Motion” (SfM) algorithms. A commercial software is applied
to investigate whether this method can be used as an alternative to other techniques. Mesh model of the some
section of the excavation section of the site were produced using point clouds were produced from the digital
photographs. Accuracy assessment of the produced model was realized using the comparison of the directly
measured coordinates of the ground control points with produced from model. Obtained results presented that
the accuracy is around 1.3 cm.
