To lighten the drivers' burden, vision based traffic sign recognition is developed as one important function in driver assistant system. In order to accurately locate traffic signs in continuous frames, traffic sign detection and tracking method is proposed in this paper. The shape and color information of traffic sign is used to detect traffic signs in single frame. To maintain detection result about traffic sign in continuous frames, Kalman filter is adopted in tracking step. The experiment results demonstrate that the proposed method can effectively detect traffic signs and track them. 收起
