| Abstract: | This paper presents a new method to regulate the traffic signs in the images taken from the real road environment.With this method,the traffic sign recognition system’s success rate can be improved.In this research,the theory of the affine transformation is first introduced,the shape change of the traffic signs in the images is analyzed,and the way to regulate the traffic signs through the affine transformation is also presented.The experimental results show the flexibility and algorithm validity of the proposed method. |
