Özet:

In this study; Underwater Photogrammetry (SAF) methods and their usage areas are discussed. Studies on underwater photogrammetry have been researched and general information has been presented. Underwater photogrammetry is used for various purposes. It is mostly used in 3D modeling of archaeological remains such as shipwrecks and coral reefs. The method known as Structure from Motion (SfM), in which three-dimensional (3D) data can be generated from motion records of objects, is also used in underwater photogrammetry. In addition, software used in other photogrammetry methods can also be used in underwater photogrammetry. But in the applications: There are differences in the photographs taken under water compared to the photographs taken in other photogrammetry methods. It was predicted that some corrections such as color and contrast correction, removing shadows and highlight reduction should be applied with image processing before being evaluated in software. Like other photogrammetry methods, underwater photogrammetry has kept pace with technological developments. Especially in the beginning, underwater photogrammetry, which was applied by divers, has gained a new momentum with the use of Unmanned Underwater Vehicles (UUV). With this study, underwater studies were researched and presented to researchers. Underwater photogrammetry also find little in the literature uses the application area within the borders of Turkey. Since such a deficiency was observed for researchers who will work in this field, general information about underwater photogrammetry was given.
