Abstract: Marine piles form base support for all sorts of structures installed around the ocean, which means that it is highly critical to ensure their stability. Thus, this study set out to detect damaged parts of piles with a drone-based photogrammetric system. The study obtained spatial imagery information by using drone operation technologies and location and photogrammetric devices installed in drones in piles constructed at the base of marine structures or independently in zones of huge tidal differences. Obtained spatial imagery information was made into ortho-images through location information and three-dimensional rotational transformation. All kinds of altered parts of pile surfaces were detected through imagery analysis based on pre-processing and edge extraction techniques. Analysis results were presented by the damaged zone and type.The findings show that three-dimensional spatial information became available by using a drone-based photogrammetric system in marine piles whose access was very low. The mean damage of 1.9 cm was detected in 21 parts in piles with 48% and 52% of damage happening in splash and intertidal zones, respectively. Damage took place in polygonal forms close to a round rather than a line. Analysis results were used to assess damage to marine piles by the zone and form and raised a need for continuous management in splash and intertidal zones. These findings can be put to active use in work related to marine spatial information as well as the maintenance of marine structures and are expected to bring extended demands and development in related industries based on various scenarios of availability
