1 Project summary, description or abstract: SDNET2018 is an annotated image dataset for training, validation, and benchmarking of artificial intelligence based crack detection algorithms for concrete. SDNET2018 contains over 56,000 images of cracked and non-cracked concrete bridge decks, walls, and pavements. The dataset includes cracks as narrow as 0.06 mm and as wide as 25 mm. The dataset also includes images with a variety of obstructions, including shadows, surface roughness, scaling, edges, holes, and background debris. SDNET2018 will be useful for the continued development of concrete crack detection algorithms based on deep learning convolutional neural networks, which are a subject of continued research in the field of structural health monitoring. The dataset is accessible online from USU digital commons: https://doi.org/10.15142/T3TD19
2 Brief description of collection and processing of data: 230 images of cracked and non-cracked concrete surfaces (54 bridge decks, 72 walls, 104 pavements) are captured using a 16 MP Nikon digital camera. The bridge decks were located at the Utah State University system, material, and structural health (SMASH) laboratory. The inspected walls belong to Russell/Wanlass Performance Hall building located on USU campus The pavement images were acquired from the roads and sidewalks on USU campus. Each image is segmented into 256 × 256 px subimages. Each subimage is labeled as C if there was crack in the subimage or U if there was not a crack. Description of files (names, or if too numerous, number of files, file type(s): 56,092 two dimensional color images with .JPG extension. Definition of acronyms, codes, and abbreviations: SDNET2018: Structural Defects Network 2018 Instruments used and units of measurements: COOLPIX L830 Nikon Digital Camera Location/GIS Coverage: Utah State University Campus, Logan, Utah, USA
