Abstract
For recognizing road signs, a camera captures image data of the surroundings of a vehicle. The image data are analyzed to determine a region that contains a potential road sign. The image region is evaluated by a first classification unit to identify a road sign belonging to a particular class based on a recognized class-specific feature. Then, the brightness or color intensity of at least a portion of the road sign is analyzed along radially extending scanning beams, to determine potential contour points of an information-bearing part of the road sign, which is then extracted and semantically interpreted in a second classification unit to determine the information content thereof.
