- 요약The three-dimensional line laser scanning technology (3D laser technology) allows transportation agencies to collect high-resolution pavement range images for achieving detailed pavement condition assessment. However, the automated and accurate detection of cracks from the collected pavement data is an essential prerequisite for achieving this goal. In recent years, deep learning (DL), particularly the convolutional neural network (CNN), has emerged as the most dominant approach for automated crack detection at the pixel level (crack segmentation). However, two major bottlenecks hinder the performance of DL-based crack segmentation. First, the diverse scenarios of real-world pavement data, such as the varied geometry of cracks and diverse patterns on the pavement, challenge the robustness of CNNs for crack segmentation. Second, the CNNs for crack segmentation have poor detail-preserving capability in capturing the precise boundary, width, and connectivity of cracks, leading to incorrect estimation of crack length and width.The objective of this study is to advance automated pavement crack segmentation by addressing the two major bottlenecks that hinder the performance of CNNs on this task. To achieve this objective, we propose two methodologies. First, we propose to improve the robustness of CNNs on crack segmentation by leveraging the local geometry inherent in pavement data. To this end, we propose the Dense Local Geometry (DLG) features based on the minimal-path technique. These features are incorporated as an additional input to the CNN, providing the network with a sense of local geometry that is tailored specifically to cracks during training. To leverage the DLG features effectively, we introduce the Hybrid Fusion UNet (HFUNet), a CNN for crack segmentation based upon the hybrid fusion strategy in deep multimodal semantic segmentation. Second, we propose to enhance the detail-preserving capability of CNNs on crack segmentation by introducing the Boundary Enhancement (BE) loss. The BE loss constructs a supervisory signal on the boundaries of segmentation regions, enhancing the network's capability to perceive small deviations and disconnectivity at the boundary of cracks during training.The proposed methodologies for crack segmentation were evaluated on a realworld range image dataset with diverse conditions. The results show that the HFUNet outperforms existing CNNs in terms of Enhanced Hausdorff Distance (EHD)score (91.13), F1-score (81.82%), Intersection over Union (IoU) (69.23%), and precision (76.55%) on pavement crack segmentation. With the additional geometrical information provided by the DLG features, the major advantage of HFUNet lies in its enhanced robustness against diverse patterns on the pavement. With the BE loss, the CNNs implemented in this study achieved improved EHD, IoU, and F1-score on crack segmentation and a significant reduction in relative crack width and length errors. The results demonstrate the effectiveness and flexibility of the BE loss in enhancing the detail-preserving capability of any network. With the BE loss, the HFUNet still achieved the best EHD score (91.79), F1- score (83.47%), IoU (71.63%), and precision (78.33%) on pavement crack segmentation.The outcomes of this research will support transportation agencies in achieving detailed pavement condition assessments by providing high-granularity and precise crack segmentation from pavement range images collected with 3D laser technology.
