A camera parameters field calibration method using dynamic control points created by unmanned aerial vehicle (UAV) is presented for large field camera difficult to calibrate air photograph on sway platform. The camera continuously shoots images when UAV is flying at the field of view, the position of UAV is measured by the designed system fixed on the sway platform, thus all the UAV′ s positions in the entire flight are used as control points for camera calibration, and the control points are easily distributed in space or in the calibration image rationally, the camera parameters are solved accurately by using the sufficient number of control points and images. The proposed method overcomes the contradiction that the condition of traditional camera calibration methods often cannot be constructed in some field experiments. The proposed camera calibration method requires low field experimental conditions that demand a minimum of coordinates of two reference points and azimuth camera optical center in the reference coordinate system on sway platform. The proposed method is successfully used in applications, such as calibrating the camera in the berthed ship.
