Crevice inspection method in bridge quality inspection

Abstract

The invention relates to a crevice inspection method in bridge quality inspection. According to the crevice inspection method in the bridge quality inspection, a machine visual technology, a modern sensor technology, a datum analyzing and treatment technology and a computer technology are merged into the bridge quality inspection, and continuous and stable crevice images of an inspected bridge areobtained, so that automatic crevice detection for bridge quality is achieved, and safe using of a bridge is ensured. The crevice inspection method comprises the steps that devices are installed, thecrevice images are collected, pre-treatment of image graying, graying level switching and image smoothing to the images is conducted, and crevice targets and image backgrounds are distinguished, so that the crevice is identified, crevice parameters are extracted, a skeleton ridge line is obtained after the crevice is thinned, burrs are removed, the crevice width is calculated, and thus the actuallargest width of the bridge crevice is obtained. According to the crevice inspection method in the bridge quality inspection, the method is scientific, the operation is easy, the inspection effect isgreat, the bridge crevice can be quickly and accurately identified, the automatic inspection level of the bridge crevice is improved, and smoothness and safety of traffic transportation are effectively ensured.

Description

technical field [0001] The invention relates to traffic construction, in particular to a crack detection method in bridge quality detection. Background technique [0002] With the increasing economic and technological development, the highway transportation industry is also developing rapidly. Bridges are an important part of traffic road construction, and are closely related to people's travel safety and smooth traffic. But at present, in view of the advantages of concrete bridges and the national conditions of our country, bridge construction is still dominated by concrete bridges. [0003] Concrete bridges are vulnerable to natural forces and human factors during construction and use, such as temperature stress, load, material aging, artificial pouring methods, etc., and damage will inevitably occur over time. There are many forms of these damages, such as concrete falling off, carbonization, cracks, steel bar corrosion, pier sinking, etc., which pose a serious threat t...

AI Technical Summary

Problems solved by technology

This method is flexible and simple to operate, but there are mainly: first, it requires technicians to go deep under the bridge, which is labor-intensive, time-consuming and labor-intensive, and it is difficult to guarantee the safety of technicians; Larger errors, high technical level requirements for technicians, and the stability and accuracy of the obtained measurement results are difficult to guarantee
