Abstract
A method and system for calibrating a camera which is arranged on an ego vessel are disclosed. The method comprises receiving image data captured by the camera, the image showing at least one imaged solid object and at least one imaged solid object interface between the imaged solid object and the imaged sky, or between the imaged solid object and an imaged water surface of a waterbody. The method further comprises extracting the imaged solid object interface from the image and determining a pose of the ego vessel at the time at which the image is captured. The method additionally comprises extracting a real solid object interface from received reference data. Furthermore, the method comprises determining a difference between the extracted imaged solid object interface and the extracted real solid object interface, and determining calibration values for the camera depending on the difference such that the difference is reduced.
