ArchImageLib: libraries of annotated and unannotated image data of masonry railway bridges and viaducts

This 'ArchImageLib' dataset contains image data for 13 masonry arch railway bridges and viaducts in the UK. Overall, it includes 44 surveyed arch spans and a total surface area of masonry of approximately 15,300 square meters. A subset of the images has been processed to generate annotations, capturing mortar joints and damage including cracking, spalling, mortar loss, and vegetation. These bridges and viaducts present in a range of structural conditions, and the dataset therefore presents a valuable resource for the training and validation of algorithms for automated inspection and damage classification. Given the increasing threats to ageing masonry infrastructure from extreme loading, including climate-driven wind and flood loading, the development of such algorithms is critical to safeguarding these assets for future generations.本"ArchImageLib"数据集收录了英国境内13座砖石拱铁路桥梁及高架桥的图像数据。整体而言，该数据集涵盖44个已勘测的拱跨，砖石结构总表面积约15300平方米。其中部分图像子集已完成标注处理，标注内容包含灰缝以及裂缝、剥落、灰浆流失、植被滋生等病害类型。这批桥梁与高架桥呈现出多样的结构状态，因此该数据集可为自动化巡检与病害分类算法的训练与验证提供极具价值的研究资源。鉴于极端荷载（包括气候驱动的风力与洪水荷载）对老化砖石基础设施的威胁与日俱增，开发此类算法对于为后世守护这类基础设施资产至关重要。
