“…However, this is a local analysis of cracks and parameters of individual cracks are measured, e.g., the opening width, crack length, etc. [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. There is a lack of research work, in which the cluster crack structure is analyzed in a global way, and the results obtained are related to material properties.…”

“…Alternatively, the displacement field-based method identifies cracks according to the displacement field of the measurement region, where the displacement field is analyzed by image analysis techniques [24,34]. Due to the high precision of image-based displacement field measurements, displacement field-based methods are capable of detecting thin cracks with widths of much less than one pixel.…”

“…Cracking in reinforced concrete structures can lead to catastrophic failure of the entire structure, due to the fact that cracks provide access to corrosive chemicals (Krauss & Rogalla, ). The current empirical methods, such as manual visual inspection for bridge condition assessment, generally involve sending trained inspectors onsite to highlight cracks with physical markings and to capture images of defects for photographic record (Dias‐da‐Costa, Valença, Júlio, & Araújo, ; G. Li, He, Ju, & Du, ; Y. Yang, Yang, & Huang, ). However, the use of manual bridge inspection to perform crack detection is subjective, time consuming, qualitative, and incapable of evaluating areas that are difficult to access or inspect (Yeum & Dyke, ).…”
