Abstract

Bridge is an important part of traffic infrastructure, and its maintenance is related to smooth traffic and even the safety of people's lives and property. Automatic detection of concrete bridge cracks is an important part of bridge maintenance. However, it is still a challenging task due to the inhomogeneous strength of concrete bridge cracks, the complexity of the background, and the weakness of the target. Currently, traditional image processing-based technology cannot detect bridge cracks well, and the typical deep learning model is not very effective when directly used to detect bridge cracks. In response to this problem, this paper proposes a bridge crack detection model based on the improved U-Net deep learning model. Compared with the original U-Net model, the convolution block of our improved model is wider in the encoding stage, and the wider convolution block enables the model to learn more semantically discriminative information. Finally, the performance of the improved model is validated on a dataset with 600 images. Experimental results show that compared with other advanced detection models, the proposed method achieves better performance in terms of average intersection ratio and pixel accuracy. Therefore, the method proposed in this paper can detect concrete bridge cracks automatically, which provides a certain reference value for bridge crack maintenance engineers based on image recognition technology.
