Automatic crack detection is a critical task in the generation of a crack map for existing concrete infrastructure inspection. This paper describes an automatic crack detection and classification method based on a genetic algorithm (GA) for optimizing image processing technique parameters (IPTs). Under various complex photometric conditions, the crack detection results of concrete infrastructure surface images remain noise pixels. Following that, a deep convolution neural network (CNN) method is used to automatically classify crack candidates and non-crack candidates. Furthermore, the … Continue reading “Research on Automatic Crack Detection for Concrete Infrastructures Using Image Processing and Deep Learning”

Vision-based Measurement of Geometric Parameters of Cracks in Concrete

The geometrical parameters of a cracked concrete surface are estimated using an optical microscope and an 8-bit RGB image generated with a high resolution camera based on close distance photography. The image’s pixel intensity distribution can be used to determine factors such as fracture breadth, depth, and shape. To estimate the crack’s geometrical dimensions, the image is converted to 16-bit grey scale, and then a mathematical relationship connecting the intensity distribution to the depth and width is derived using the … Continue reading “Vision-based Measurement of Geometric Parameters of Cracks in Concrete”
