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.
The paper associated with this dataset (ArchScanLib and ArchImageLib: Libraries of point cloud and photogrammetry data of ageing masonry arch bridges and viaducts) is currently embargoed, and will be available through this link once published.
