With the continuous progress of science and technology, the magnetic material industry continues to emerge new types of magnetic materials, such as high-performance permanent magnet materials, soft magnetic materials, improve the permeability, etc., to promote the development of the magnetic material industry.

The popularity of the magnetic material market and the increasing complexity of the process, accompanied by various appearance defects, poor size and other problems have gradually become prominent, seriously affecting the quality of magnetic materials, magnetic materials because of small size, large batch to the production process of the detection of greater difficulty. The traditional magnetic material size detection depends on manual, subject to subjective, condition, speed and other reasons, the detection efficiency is low, the stability is poor, easy to appear false detection and missing detection phenomenon.

Machine vision technology enables traditional mechanical equipment, improves the quality of detection and classification, improves the efficiency of detection, saves labor costs and other advantages gradually replace the traditional manual detection, and meets the needs of automated production detection.

Magnetic dimension visual inspection scheme

The size detection content mainly includes the length, width and height of the magnetic material.

Use a camera or other image acquisition equipment to photograph the measured object and obtain its image data.

The feature information of the object, such as edge, corner, contour, etc. is extracted by image processing algorithm, and the position and shape of the object to be measured are identified in the image.

Based on the result of feature extraction, the size of object is measured and analyzed by computer vision algorithm.

Finally, the results of the dimensional measurement are output in digital form, usually in the form of length, width, height and other parameters.
