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.

Abstract: A method of labelling a water surface within an image is provided. The method includes: receiving image data of the image generated by a camera, the image including at least one water surface; receiving water surface extension data, the water surface extension data being representative of an area over which the water surface extends in the real world; matching the water surface extension data to the image data based on a spatial relationship between the camera and the area of the water surface; and labelling the water surface in the image based on the matched water surface extension data.
