Abstract

The invention discloses a method and a device for identifying the collapse area of a magnetic tile. The method comprises the following steps: acquiring a magnetic tile product image of a magnetic tileproduct to be detected; acquiring a magnetic tile detection area in the magnetic tile product image in a predetermined way; determining a feature area in the magnetic tile detection area by Fourier transform, wherein the feature area is an area where the magnetic tile product is in collapse; and performing image enhancement processing on the feature area, and determining a collapse area in the magnetic tile product based on the feature area being subjected to the image enhancement processing. Through adoption of the method and the device, the technical problem of relatively low reliability ofa detection result caused by manual inspection of the collapse defect of the magnetic tile product in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a method and device for identifying a magnetic tile collapse area. 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 chipping 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 the chipping defects of magnetic tile products. On the other hand, humans cannot concentrate on focusing on small cracks and defects for a long time, which will lead to a high misjudgment rate in the detection results of magnetic tile products. [0003] Aiming at the problem of low reliability of detection results caused by manual detection of chipping defects of magnetic tile products in the above-mentioned rela...
