Problems solved by technology

[0004] The traditional manual detection method is dangerous, high cost and low work efficiency
Therefore, at present, some bridge crack detection methods based on image processing algorithms have been developed to liberate manpower. Connectivity causes breakage, which changes the continuity of cracks and affects the reliability of bridge crack detection

Abstract

The invention discloses a bridge crack detection method and system. The method comprises the steps that S1,conducting image collection on a bridge crack area; S2, minimizing the influence of texturesand details outside the crack region by adopting wavelet transformation; S3, removing noise blocks in the image by adopting an image morphological analysis method, and preliminarily segmenting crackinformation; and S4, connecting the disconnected cracks by adopting a crack connection method, filling small connected domains between the connecting lines, and further segmenting out complete cracksto realize bridge crack detection. When the cracks are detected, the connectivity of the cracks is not damaged, and the connectivity in a crack area or between edge pixels is not influenced, so that the complete skeleton structure of the crack can be truly represented, the detection reliability of the bridge cracks is improved, and the accurate assessment of the damage degree of the bridge is facilitated.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge crack detection method and system. Background technique [0002] With the rapid development of national projects such as my country's economic development, urbanization, and high-speed rail, the number of bridges built to cross obstacles in the construction of roads, railways, or urban and rural water conservancy has increased rapidly. Bridges play an important role in the development of the national economy. It plays a pivotal role and is also a manifestation of our country's comprehensive strength. [0003] As the hub of traffic systems such as roads, highways, and railways, bridges need to be regularly evaluated for their health status, and bridge cracks, as one of the most important bridge diseases, seriously affect the safe operation of bridges, and more serious ones will occur Bridge crash accident. Therefore, it is very important to detect bridge crack...
