Embodiment Construction

[0060] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0061] Such as figure 1 As shown, it is a magnetic tile surface defect detection system provided by an embodiment of the present invention. The system includes: an image acquisition device 4 and a computer system 12;

[0062] The image acquisition device 4 is used to collect the surface image of the magnetic tile and transmit the surface image of the magnetic tile to the computer system 12;

[0063] The computer system 12 is used to determine whether there is a suspicious area in the surface image of the magnetic tile, and when there is a suspicious area, the suspicious area is segmented to obtain an image of the suspicious area, and the geometric features, gray-scale features and texture features of the image of the suspicious ar...

Abstract

The invention relates to a magnetic shoe surface defect detection system and method, and relates to the field of magnetic shoe surface defect detection. The system comprises an image acquisition device and a computer system. The image acquisition device is used for acquiring magnetic shoe surface images. The computer system performs suspicious area judgment on the magnetic shoe surface image and divides the suspicious area to acquire a suspicious area image. The computer system extracts geometric features, gray features and texture features of the suspicious area image. The computer system inputs the geometric features, the gray features and the texture features into a classifier which is trained in advance. The detection result of the magnetic shoe surface defects is obtained, high-precision classification and identification of the magnetic shoe defects are realized through a classification and identification algorithm, automatic detection of the magnetic shoe defects is realized, thelabor cost is reduced, and the efficiency and the identification accuracy are improved.

Description

Technical field [0001] The invention relates to the field of surface defect detection of magnetic tiles, in particular to a system and method for detecting surface defects of magnetic tiles. Background technique [0002] Permanent magnet ferrite magnetic tile (magnetic tile for short) is a tile-shaped permanent magnet widely used in electric motors. Different kinds of defects are prone to appear in the production and processing process, and these defects directly affect the performance and life of the motor. At present, the method of detecting the surface defects of the magnetic tile is mainly manual visual inspection. This method has problems such as different standards, low efficiency, and missed inspections. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic tile surface defect detection system in view of the deficiencies of manual detection of magnetic tile surface defects in the prior art. [0004] The techni...
