Deep transformer networks for precise pothole segmentation tasks

Abstract

Potholes on the road surface are a significant safety hazard and can cause severe damage to vehicles. Identifying and repairing potholes is a challenging task that requires efficient and accurate methods. In recent years, deep learning models, such as U-Nets and transformers, have been used for image segmentation tasks with promising results. This paper proposes a transformer-based model and in particular the SegFormer framework, for pothole segmentation using high-resolution images captured from a road inspection vehicle. The proposed network outperformed the traditional U-Net model that demonstrates state-of-the-art performance in various segmentation tasks, achieving an average F1-score close to 80%. The results show that the proposed method can effectively identify and localize potholes, providing a useful auxiliary tool for road maintenance and safety.
