Abstract

The invention discloses a crack identification method and device. Among them, the method includes: obtaining the magnetic tile product image of the magnetic tile product to be detected; obtaining the target detection area of ​​the magnetic tile product image based on a predetermined method; extracting the characteristic region in the target detection region, wherein the characteristic region is the magnetic tile product The area where cracks exist; the initial crack lines are extracted from the feature area, and the target crack lines are obtained according to the initial crack lines. The invention solves the technical problem of low reliability of detection results caused by manual detection of crack defects of magnetic tile products in the related art.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a method and device for identifying cracks. Background technique [0002] The consistency of magnetic tile products is poor, and the surface drawing texture characteristics and color uniformity are not good. At present, the detection of surface crack defects of magnetic tiles mainly relies on manual visual inspection, which not only leads to low detection efficiency of magnetic tile products. Low, it is impossible to accurately detect crack defects in magnetic tile products. On the other hand, humans cannot concentrate on focusing on tiny crack defects for a long time, which will lead to a high misjudgment rate in the test results of magnetic tile products. [0003] Aiming at the problem of low reliability of detection results caused by manual detection of crack defects of magnetic tile products in the above-mentioned related technologies, no effective solution has bee...
