1. A method for detecting beacons in the surroundings of an ego vehicle, the method comprising:
capturing a sequence of camera images of a section of the surroundings by a camera system of the ego vehicle,
detecting bright light spots in at least one camera image of the sequence of captured camera images, wherein the bright light spots are ten to fifty brightest regions in a particular color channel,
cutting out regions containing the detected bright light spots in the camera image,
classifying the cut-out regions, classifying the bright light spots as beacons if the classified bright light spots are
detected repeatedly and therefore a threshold value of a counter is exceeded, and incrementing the counter until a predetermined number of positive detections of the classified bright light spots is achieved, wherein the counter is incremented after each detection of the classified light spots and is decremented if a detection of the classified light spots is not achieved.
