System for carrying out image acquisition and analysis on crack defects of bridge structure

Abstract

The invention discloses a system for carrying out image acquisition and analysis on crack defects of a bridge structure. The system comprises a crack image acquisition subsystem, a crack analysis and database management subsystem and a power-supply and support subsystem, wherein the image acquisition subsystem mainly comprises a crack imaging device (1), a distance sensor (2), an angle sensor (3) and a data transmission device (4); the crack analysis and database management subsystem is composed of a portable computer (5) and a set of self-researched image processing and database management software; and the power-supply and support subsystem is composed of a high-energy battery (6) and a support platform (7). The system disclosed by the invention has the characteristics of high efficiency, rapidness and convenience, and can be widely used in the field of bridge inspection.

Description

technical field [0001] The invention relates to the field of bridge detection, in particular to an image acquisition and analysis system for crack defects in bridge structures. Background technique [0002] Highway traffic is the main artery of the national economy, and the bridge engineering structure is the throat of highway traffic, which plays a vital role in ensuring the smoothness of the highway. However, after the bridge is completed and opened to traffic, with the passage of time, various factors will reduce the safety of the bridge, such as: the original design does not meet the requirements for use, the construction does not meet the design requirements, the bridge has diseases, and the materials are aged and corroded and not in time. Maintenance, increase in vehicle load or sharp increase in traffic volume, damage to bridge expansion joints or adverse effects on bridge structure caused by uneven bridge deck, etc. At present, only from the factor of increased vehi...

Problems solved by technology

[0008] The traditional detection method is the method of artificial visual recognition. Usually, the search and shape of cracks are measured and recorded by investigators through microscopes. This method has the disadvantages of closed traffic, heavy detection workload, long detection time, high detection cost, and artificial detection results. Factors greatly affect the shortcomings. At the same time, the inspectors need to go deep into the area where the crack is located through the inspection vehicle or scaffolding, which also brings many unpredictable safety hazards to the inspection.
