Historical and cultural artifacts provide information about ancient life, language, religion,
literature, traditions and architecture. Documentation of cultural artifacts is of great
importance in terms of protecting and transferring them to future generations. In recent years,
Structure from Motion (SfM) can be used to generate dense point cloud, ortho-image, linedrawings, and 3D models in addition to the classical terrestrial photogrammetry methods. The
fast documentation and archiving studies can be carried out by SfM approach using low-cost
cameras with cost effective project budget. In this study, it is aimed to produce line-drawing,
ortho-image, and 3D models of Mehmet Ali Bey Fountain by using SfM approach. The Mehmet
Ali Bey Fountain is one of the registered historical structures in the "Monuments" class among
registered immovable cultural assets throughout Turkey, located in the Abbasaga District of
Besiktas/Istanbul from the Ottoman Sultan II. Mahmut period. The installation and
measurement of the control points were conducted, and the image acquisition was performed
with convergent image acquisition method. The 3D point cloud generation of Mehmet Ali Bey
Fountain was performed after image orientation steps. The productions of 3D model, orthoimage, and line-drawing have been carried out successfully using the produced point cloud. In
this study, all processes for the documentation of historical structure were carried out using
“Agisoft Metashape Professional” and “Autocad” software. The analyzed measured distances
between the GCPs and corresponding distances from 3D model (standard deviation of the
differences is 0.5 cm) proved the success of the SfM method for documentation of registered
historical artifacts and cultural heritage.
