Abstract
Traffic sign recognition technology is very important in intelligent transportation systems. Aiming at the problem that the imbalance of existing traffic sign data sets affects the recognition accuracy. Firstly, this paper introduces the Weighted-Hybrid loss function in VGG-16 to enhance the feature extraction ability of the model. The model can reduce the contribution of easy-to-classify samples to the decline of the loss function. Then, we introduce the HDC-VGG lightweight model to ensure the accuracy of model recognition on the basis of reducing model parameters. Finally, the experiment results show that the recognition accuracy of the proposed model can reach 98.2%.
