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...
