The invention relates to a bridge steel cable fracture detection method and system based on target segmentation, and belongs to the technical field of bridge steel cable detection.The method comprises the steps that multiple bridge steel cable images are collected to serve as a data set, and the bridge steel cable images comprise steel cable fracture images; constructing a broken cable segmentation network; training a broken cable segmentation network by adopting the data set to obtain a broken cable segmentation model; carrying out bridge steel cable fracture detection on the to-be-detected bridge steel cable image by adopting the broken cable segmentation model; the broken cable segmentation network comprises an encoder, a first multi-type information focusing structure, a second multi-type information focusing structure, a third multi-type information focusing structure and a decoder; through convolution operations of convolution kernels of different scales and up-sampling operations of different multiples, semantic information and fine-grained information of different degrees are captured from each coding unit, the information proportion of different features in an output feature map can be adjusted and optimized, the broken cable segmentation accuracy is improved, and meanwhile, the low detection cost is ensured.
Description
technical field [0001] The invention relates to the technical field of bridge steel cable detection, in particular to a method and system for bridge steel cable fracture detection based on target segmentation. Background technique [0002] Suspension bridges are the main bridge type used for long-span and extra-long-span highway bridges in China. As the main load-bearing member of the suspension bridge, the steel cable bears the coupling effect of the external environment and random loads for a long time, and is prone to fracture during the service period. serious threat. [0003] At this stage, the monitoring of the service condition of steel cables mainly relies on various cable force detection technologies. Among them, the fiber grating method has the best test effect and repeatability, but it has the disadvantages of high application cost and irreplaceable after damage. . Therefore, there is an urgent need to explore an accurate, reliable and low-cost method for bridg...
