Zusammenfassung: | The invention discloses a vehicle brand recognition method. The method comprises the steps of firstly obtaining and extracting a vehicle lamp region from a to-be-identified vehicle picture; preprocessing the vehicle lamp area to obtain a to-be-detected vehicle lamp boundary contour; dividing the boundary contour of the to-be-detected vehicle lamp into 16 directions at equal intervals, and calculating direction chain codes in each direction in the boundary contour of the to-be-detected vehicle lamp to obtain 16 direction chain codes; calculating the similarity between the to-be-detected vehiclelamp boundary contour and each vehicle lamp boundary contour in a brand library according to all the direction chain codes, and outputting a selected vehicle lamp boundary contour from the brand library according to the similarity; and extracting the vehicle brand corresponding to the selected vehicle lamp boundary contour as the vehicle brand of the to-be-identified vehicle. By adopting the technical scheme of the inven |
