The invention discloses a concrete structure surface crack detection method and system, and relates to the technical field of concrete crack detection. The method includes: obtaining regional images of multiple regions on the surface of the concrete structure to be tested captured by an industrial camera; splicing and fusing the regional images to obtain a panoramic image; using a crack detection algorithm based on a seepage model to detect cracks in the panoramic image to obtain a panoramic image Cracks in the image; the coordinates, width and length of the cracks are calculated and stored. The invention adopts the regional image of the surface of the concrete structure to be measured by the industrial camera to realize the long-distance and long-term detection of the width, length and distribution of the cracks in a certain area on the surface of the structure. The advanced crack detection algorithm performs crack detection on panoramic images, which can detect tiny cracks larger than 1 / 5 pixel size, which greatly improves the resolution of crack detection.
Description
technical field [0001] The invention relates to the technical field of concrete crack detection, in particular to a method and system for detecting cracks on the surface of concrete structures. Background technique [0002] Among the cracks, honeycombs, pockmarks and pits of concrete structure diseases, cracks are the most destructive and threatening one. Taking the bridge structure as an example, the relevant literature data show that cracks cause more than 90% of the total number of damaged bridges to be damaged. Cracks are very harmful to concrete bridges, and are especially prone to safety accidents such as bridge collapse. Based on this, people pay more and more attention to the regular detection and maintenance of bridge cracks. [0003] The most traditional method of detecting bridge cracks is manual detection, but the manual detection method is easily affected by human subjective factors, the measurement results are unstable, and the accuracy and efficiency are ver...
