Abstract:

Traffic sign recognition plays an important role in safe driving, especially under the condition of illumination change and occlusion. Automatic recognition of traffic signs with high accuracy and high real-time performance needs to be resolved. This paper reviews the detection of traffic sign and the recognition of traffic sign. And the principles, steps, characteristics and performances of the algorithms are introduced, as well as the common traffic sign databases for algorithm research. Compared with traditional detection and recognition methods, deep learning algorithms is helpful to solve the difficult problems of traffic sign recognition under the condition of illumination change and partial occlusion, which is the main way to improve the performance of automatic driving and unmanned driving in the future.

Key words: traffic sign detection, traffic sign recognition, deep learning
