METHOD FOR DETERMINING THE POSITION OF A WATERCRAFT BY MEANS OF OPTICAL BEARING

The invention relates to a method for determining the position of a watercraft (CS) by taking a bearing on at least two marks (M1, M2) of known position, characterized by the steps of: capturing at least one first image containing at least one first mark (M1) of known position by means of a camera arranged on board the watercraft (CS), the optical axis of which camera is oriented at a known camera angle relative to a predefined coordinate system and which camera has a conformal resolution at least in the horizontal; ascertaining the first line of position (S1) connecting the first mark (M1) to the camera by marking the first mark (M1) in the first image captured by the camera; ascertaining a second line of position (S2) connecting a second mark (M2) to the camera by marking a second mark (M2) in the first image captured by the camera or in a second image captured by the camera; and determining the position of the watercraft (CS) by means of the first line of position (S1) and the second line of position (S2).
