1. A method for linking optical flow across a plurality of images of an image detection device for a vehicle, the method comprising the following steps:
selecting at least one tile from a track map, the track map including a plurality of flow tracks and being subdivided into a plurality of tiles; and
extending at least one flow track of the flow tracks encompassed by the tile, using a flow vector of a flow map that is associatable with the flow track, the flow map including a plurality of flow vectors that are based on a present image of the plurality of images, wherein in the step of extending, a quantization error of the flow track is updated, wherein the quantization error indicates a deviation between a quantified end point of the flow track and an actual end point of the flow track.
