Problems solved by technology

However, the original subject research knowledge has completed the preliminary identification and rapid recording of crack images, but there are still problems such as too many long-distance acquisition equipment, not easy to operate on site, and unable to intelligently and quickly identify the nature of cracks. The integrated mechanism of crack automatic collection, at the same time, it is necessary to upgrade the original crack intelligent processing software so that it can quickly and intelligently judge the nature of cracks

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] A method for intelligent identification and classification of cracks, comprising the following steps:

[0036] (1) If figure 1 Shown: First create the crack template database:

[0037] (1) read the crack sample image, and process the color image into a grayscale image;

[0038] (2) Using image analysis method to automatically obtain cracks;

[0039] Use the image projection and peak detection method to separate the crack area, process the read image into a histogram, and locate the image area to be processed according to the peak value of the histogram, and then segment it;

[0040] (3) Extract the features of the crack;

[0041] Generate fracture templates using vertical and horizontal projections and normalization;

[0042] (4) save the generated crack template to the database;

[0043] (2) If figure 2 Shown: Then the identific...

Abstract

The invention discloses a crack intelligent identification classification method. A crack can be automatically obtained by means of an image analysis method, for example, the cracking area is separated by image projection and a peak value detection method; the features of the crack are extracted, for example, a crack template is generated by means of vertical and horizontal projection and normalization processing; and at the end, the crack type is determined by comparing with a known database, for example, the type of the crack can be automatically identified by the high-speed matching with the known standard template of a crack template base. The crack intelligent identification classification method can be used for rapidly determining the crack property.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic intelligent identification and classification method for crack patterns on walls. Background technique [0002] After the building is built and put into use, due to various human or natural factors, a large number of cracks will be generated on the surface, especially now that a large number of subways and deep foundation pits are excavated, causing large areas of surrounding houses to vibrate and generate cracks. At the same time With the improvement of people's living standards, the requirements for the quality of life will also increase accordingly. Users will worry about whether these cracks will affect the safety of the house, so the demand for the identification and detection of these cracks will also increase. Timely and effective investigation and identification of these houses may cause residents' dissatisfaction with government departments, and eve...
