Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for detecting changes in concrete cracks, which solves the problem that the existing concrete cracks proposed in the above background technology have less detection data during the detection process, and cannot accurately determine the location, location, and location of concrete cracks. The direction, depth and width are fully detected, and there may be interference data, which cannot fully understand the changes in concrete cracks, and it is not convenient to predict the changes in concrete

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0025] A method for detecting changes in concrete cracks, comprising the following specific steps:

[0026] (1) Collect images of concrete cracks

[0027] The image acquisition device moves horizontally above the concrete to acquire images of concrete cracks. During this process, the light intensity can be increased through the supplementary light to improve the shooting effect. The image acquisition device moves horizontally, and the movement method is on the concrete detection surface. Set up a horizontal moving track;

[0028] (2) Drawing concrete crack images

[0029] Send the concrete crack image to the image processing system for processing to obtain the crack in...

Abstract

The invention discloses a method for detecting concrete crack changes. A concrete crack detection method relates to the technical field of concrete crack detection, and comprises the following specific steps: (1) acquiring a concrete crack image; (2) drawing the concrete crack image; (3) acquiring concrete crack data; (4) acquiring a concrete crack three-dimensional composition; the invention discloses a method for detecting concrete crack change. A concrete crack image can be obtained through the image collection device; the position, direction, depth and width information of the concrete crack can be obtained through the ultrasonic detection device; the three-dimensional construction graph of the concrete crack is convenient to construct, the data detection precision is improved throughmultiple times of repeated data detection, sufficient detection data can be obtained, the change condition is convenient to compare, and the change condition of the concrete crack is fully understood.

Description

technical field [0001] The invention relates to the technical field of concrete crack detection, in particular to a method for detecting changes in concrete cracks. Background technique [0002] Concrete is a general term for composite materials that are composed of gel material, aggregate and water in an appropriate proportion, and then hardened after a certain period of time. Concrete cracks are the physical structural changes of concrete structures due to the effects of internal and external factors, and cracks are the main reason for the reduction of the bearing capacity, durability and water resistance of concrete structures. Therefore, in the process of building construction, it is necessary to detect the changes of concrete cracks. [0003] Existing concrete cracks have less detection data during the detection process, and the position, direction, depth and width of concrete cracks cannot be fully detected, and there may also be interference data, so it is impossible...
