The invention relates to a method for correlating optical flow on a plurality of images of an image detection device for a vehicle (100). At least one tile is selected from a track map, wherein the track map comprises a plurality of flow tracks and is divided into a plurality of tiles. Subsequently, at least one flow track comprised by the tile is extended using flow vectors of a flow map which can be assigned to the flow track. Here, the flow map comprises a plurality of flow vectors based on a current image of the plurality of images.
