Abstract

The invention discloses a method and a device for identifying cracks. The method comprises the following steps: acquiring a magnetic tile product image of the magnetic tile product to be detected; acquiring a target detection region of an image of a magnetic tile product based on a predetermined manner; extracting a feature region in a target detection region, wherein the feature region is a region in which cracks exist in a magnetic tile product; the initial crack line being extracted from the characteristic region and the target crack line being obtained according to the initial crack line.The invention solves the technical problem of low reliability of the detection result caused by detecting the crack defect of the magnetic tile product in an artificial manner 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...
