Photogrammetric techniques have known an important development during the last decade and today they are widely employed for 3D acquisitions in different fields of application. In the paper underwater photogrammetry was taking into account with the aim to analyze the effects of different parameters (ambient light and water turbidity) on the quality of the 3D reconstruction. Several experimental tests were performed on a wind turbine blade using a common action camera, the GoPro 4 black edition and commercial software.
