Abstract

The invention relates to a bridge cable fracture detection method and system based on target segmentation, which belongs to the technical field of bridge cable detection. The method includes: collecting multiple bridge cable images as data sets, and the bridge cable images include cable fracture image; build a broken cable segmentation network; use the data set to train the broken cable segmentation network, and obtain the broken cable segmentation model; use the broken cable segmentation model to detect the bridge steel cable fracture in the bridge cable image to be detected; the broken cable segmentation network includes encoder, The first multi-type information focusing structure, the second multi-type information focusing structure, the third multi-type information focusing structure and decoder; through convolution operations of different scale convolution kernels and upsampling operations of different multiples, capture from each coding unit Different levels of semantic information and fine-grained information, and the ability to adjust and optimize the information ratio of different features in the output feature map, improve the accuracy of broken cable segmentation and ensure the low cost of detection.

Description

technical field [0001] The invention relates to the technical field of bridge steel cable detection, in particular to a bridge cable fracture detection method and system based on target segmentation. Background technique [0002] Suspension bridge is the main bridge type adopted by long-span and extra-long-span highway bridges in China. As the main load-bearing component of the suspension bridge, the steel cable has been subjected to the coupling effect of the external environment and random loads for a long time, and it is prone to breakage during service. serious threat. [0003] At present, the service state monitoring 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 non-replacement after damage, so it is difficult to be widely used. . Therefore, it is urgent to explore an accurate, reliable and low-cost ...
