Embodiment Construction

[0052] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and specific conditions.

[0053] In the specific implementation of the present invention, a crack detection method in bridge quality detection comprises the following steps:

[0054] (1) Installation equipment:

[0055] Depend on figure 1 As shown, the detection vehicle 1 is driven to the top of the area to be detected on the bridge 2, and the downward mechanical arm 3 is installed on the detection vehicle 1, and the linear track 5 parallel to the bridge to be tested part 10 is installed on the lower part of the mechanical arm 3. The track 5 is fixed on the working platform installed on the pier 4, and the traveling trolley 8 is installed on the linear track 5, so that the traveling trolley 8 reciprocates along the linear guide rail 5, and the traveling trolley 8 and the control host (optional, shown in the figure (not shown) are connec...

Abstract

The invention relates to a crack detection method in bridge quality detection, which can effectively solve the problem of integrating machine vision technology, modern sensing technology, data analysis and processing technology, and computing technology into bridge quality detection to obtain continuous and stable cracks for the bridge to be detected Image, in order to realize the automatic detection of bridge quality cracks and ensure the safe use of bridges, the method is to install equipment, collect crack images, and perform image grayscale, grayscale transformation, and preprocessing of image filtering on the image. The crack target and The image background is distinguished to identify cracks, extract crack parameters, refine cracks to obtain skeleton ridges, remove burrs, calculate crack width, and obtain the real maximum width of bridge cracks. The method of the invention is scientific, easy to operate and good in detection effect, can quickly and accurately realize the identification of bridge cracks, improves the automatic detection level of bridge cracks, and effectively guarantees smooth and safe transportation.

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...
