Embodiment Construction

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

[0061] Such as figure 1 As shown, 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 judge whether there is a suspicious area in the surface image of the magnetic tile, and when there is a suspicious area, segment the suspicious area to obtain an image of the suspicious area, and extract geometric features, grayscale features and texture features of the image of the suspi...

Abstract

The invention relates to a magnetic tile surface defect detection system and method, and relates to a magnetic tile surface defect detection collar. The system includes: an image acquisition device and a computer system; the image acquisition device is used to collect the surface image of the magnetic tile, and the computer system judges the suspicious area on the surface image of the magnetic tile and divides the suspicious area to obtain the suspicious area image, and extract the geometric features, grayscale features and texture features of the suspicious area image, and the computer system inputs the geometric features, the grayscale features and the texture features into a pre-trained classifier to obtain The detection results of magnetic tile surface defects, through the classification recognition algorithm, realize high-precision classification and identification of magnetic tile defects, and realize automatic detection of magnetic tile defects, reduce labor costs, improve efficiency and recognition accuracy.

Description

technical field [0001] The invention relates to the field of magnetic tile surface defect detection, in particular to a magnetic tile surface defect detection system and method. Background technique [0002] Permanent ferrite magnetic tile (abbreviated as magnetic tile) is a tile-shaped permanent magnet widely used in electric motors. Different types 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 surface defects of magnetic tiles is mainly manual visual inspection. This method has problems such as inconsistent standards, low efficiency, missed detection and false detection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic tile surface defect detection system for the deficiencies of manual detection of magnetic tile surface defects in the prior art. [0004] The technic...
