A visual localization method based on roadside landmarks is proposed in this paper. This method uses a single image obtained by a high-speed camera fixed on the top of the vehicle to accomplish real-time positioning. The information and characteristics of roadside landmarks is extracted and recognized from the image obtained. The distance between landmark and camera optical center is calculated according to the shape of the landmark. Finally, the vehicle position is calculated with the distance and the landmark database, which contains the characteristics and position of the landmark. Static and dynamic experiments are carried out and the results demonstrate that the proposed method can achieve vehicle positioning. Under the condition of an actual distance is below 40 m, the average positioning error is below 1m.
