Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0054] see figure 1 , figure 2 , image 3 , Figure 4 A method for identifying characteristic information of concrete cracks, the specific steps are as follows:

[0055] 1. Fracture image acquisition and fracture image preprocessing

[0056] The image acquisition device is used to collect the image of the crack, and then the crack image is pre-processed, and the pre-processing includes graying, smoothing and sharpening of the crack image;

[0057] 2. Crack image recognition processing

[0058] The fracture image obtained in step 1 is recognized and processed by the two-dimensional Otsu method and or the Markov segmentation algorithm. In the two-dimensional Otsu method, the fracture image For M gray levels, the crack image The interval between any pixel in the area and its neighboring pixels is (0~M-1), and the set of...

Abstract

The invention relates to a method for identifying concrete crack characteristic information. The method comprises the steps of acquiring an image of a crack, carrying out pretreatment on the crack image in sequence, wherein the pretreatment comprises image graying, smoothing and sharpening, identifying the crack image by adopting a two-dimensional OTSU method or a Markov segmentation algorithm, judging the type of the crack image by adopting a projection method, and finally analyzing the crack image by using a computer control system to extract the crack characteristic information. In the process of extracting the crack characteristic information, the computer control system can extract the crack characteristic information automatically and quickly in a mass mode, and structural state assessment is completed by combining with physical parameters, thereby accomplishing the whole process of identifying the concrete crack characteristic information. The method provided by the invention carries out long-distance, quick and accurate detection on surface cracks caused by cracking and damages of a concrete structure through the computer controls system, provides effective parameters for structural state assessment and the like, and greatly improves the rapidity, the accuracy and the scientificity of detection.

Description

Technical field [0001] The invention involves the field of concrete crack recognition technology, which is specifically an identification method of a concrete crack feature information. Background technique [0002] Concrete structures such as bridge structures, industrial and civil buildings, etc. will have different degrees of cracks during the construction and use.Become the qualitative and quantitative evaluation indicators during the destruction of the building, and the crack also affects the aesthetics of the structure and durability of the structure. Therefore, regular inspection and maintenance of the cracks is performed.very necessary.Traditional crack detection methods mainly depend on tools such as width and ruler, and manually operate, not only slow and time -consuming.With the development of photography technology and computer technology, the use of digital image processing technology provides new methods for the identification of concrete crack information. The rese...
