“…Although the several applications of photogrammetric measurements are currently in use and demonstrated to provide very accurate measurements for a wide variety of disciplines, its use is usually limited to small measurement volumes and experiments that are performed in laboratories or similar controllable environments. Within this small measurement volume it can be efficiently used for different purposes such as; -3D shape determination, modeling and reverse engineering (4), (5), (6) -Static or dynamic deformation measurements (7), (8), (9), (10), (11), (12), (13) , (14), (15) -Modal analysis and system identification (16), (17), (18), (19), (20), (21) This technology was for the first time applied on a MW scale wind turbine within the scope of this work. The 3D dynamic response of the rotor was captured at 33 different locations simultaneously by using 4 CCD (charge coupled device) cameras while the turbine was rotating.…”
