摘要：TSR (Traffic sign recognition) has been studied for realizing drivers assisting system and automated navigation and is an importantstudied field in ITS (Intelligent traffic system). In this paper, a recognition method of traffic signs separated from real image wasstudied. Images were divided into several categories according to the actual weather, distance and angle of view etc. SIFT was firstlyused to detect keypoints and describe them because the SIFT(Scale Invariant Feature Transform) features were invariant to imagescale and rotation and were robust to changes in the viewpoint and illumination. And then the Bag-of-words method was applied torecognition. Finally, the SVM(Support vector machine) approach was used in classification. As shown by the experiment results, theproposed method is effective.
