Problems solved by technology

[0003] However, the detection of bridge cracks with this device still requires manual observation. Not only does each person have different criteria for judging whether cracks in different parts, widths, and lengths belong to stressed cracks, but also the responsibility of the observers is different. There is also "turning a blind eye" Fraudulent acts, etc., directly affect the authenticity, correctness, and reliability of the load test data of bridge components

Embodiment approach

[0137] As an optional implementation, the detection method also includes:

[0138] Obtain pre-collected crack image information;

[0139] Based on the crack image information, extract the crack commonality in the image containing cracks;

[0140] Cracks in images of components are identified based on crack commonality.

[0141] This implementation scheme adopts a machine self-learning method to learn to identify cracks, which reduces the difficulty of identification and improves the identification rate.

[0142] Another object of the present invention is to provide an automatic detection system for cracks in concrete components, including:

[0143] an image acquisition unit, configured to acquire the image of the component;

[0144] a grayscale information extraction unit, configured to extract grayscale information in an image;

[0145] a gray area determination unit, which determines the gray area in the image according to the gray level information;

[0146] A crack id...

Abstract

The invention discloses a concrete member crack auto-detection apparatus, method and system. The apparatus, method and system acquire a crack image generated when a bridge member is under loading through an image acquirer and transmit the image to an image processing system for processing, and image information of a crack generated in the member is acquired. The apparatus, method and system acquires the crack information of a member by means of automatic image acquisition, whether cracks at different parts and having different widths and lengths belong to qualification criteria for stressed cracking can be judged objectively according to the image information, the image information allows data to be uploaded to a railway engineering construction information management platform data center, it is convenient to acquire loading test data of a bridge member, and loading test data of the bridge member is truer, more correct and more reliable.

Description

technical field [0001] The invention relates to the field of component quality inspection equipment, in particular to an automatic detection device, method and system for concrete component cracks. Background technique [0002] Such as Figure 8 As shown, there is an automatic control device for bridge static load test in the prior art, which includes a test master control device for controlling the entire test process, and also includes a loading execution device, a load measurement device, and a deflection measurement device all connected to the test master control device. device, deviation checking device and abnormal alarm device. The test master control device is also equipped with a remote monitoring device for data upload and image remote monitoring, a manual emergency device, a fully automatic / semi-automatic device, and a one-key control device for completing the entire test process through one-key operation. The device realizes synchronous loading of bridge static ...
