Abstract
A method and a system for determining a region of water clearance of a water surface are disclosed. The method includes receiving image data of an image captured by a camera, determining water surface pixels of the image from the image data, determining image coordinates of at least a first group of the determined water surface pixels in an image coordinate system, determining a position and an orientation of the camera at the time the image has been captured, determining real-world coordinates of the corresponding water surface in the real world by transferring at least the image coordinates of the first group to a real-world coordinate system under consideration of the determined position and orientation of the camera, and determining a region of the water surface, which is defined by the determined real-world coordinates of the first group, as the region of water clearance.
