Image processing system for surface detection of coiled material

Abstract

The invention discloses an image processing system for the surface detection of an coiled material, which comprises a light source, a linear array camera group and a control cabinet, wherein the light source is used for providing light for the linear array camera group; the linear array camera group is used for capturing the original image information of the surface of the coiled material, performing early image processing of the original image information to obtain the result of the early image processing; and the control cabinet is used for performing post image processing according to the result of the early image processing to obtain the result of the post image processing. The image processing system for the surface detection of the coiled material can overcome the defects of high labor intensity, high cost, high loss rate, low detection precision and the like in the prior art and has the advantages of small labor intensity, low, cost, low loss rate and high detection precision.

Description

technical field [0001] The invention relates to coil surface detection technology, in particular to an image processing system for coil surface detection. Background technique [0002] As we all know, coiled material refers to thin materials such as film, paper, tin foil and steel plate. These materials have a common characteristic in the production process, that is, high speed. The speed of the production line is basically hundreds of meters per minute. Some even Can reach thousands of meters. In addition, due to the processing technology of coil products, defects or flaws often occur in the product itself during the production process; for example, film paper may have oil spots, voids and wrinkles, etc., while steel plates may have print defects. [0003] In the prior art, the detection of such defects is basically completed by the naked eyes of the operators on site. However, due to factors such as operator fatigue and technical quality, problems such as missed inspect...

AI Technical Summary

Problems solved by technology

[0007] (1) Large amount of manual labor: due to the high speed of the coil production line, the detection of defects is completed through the naked eyes of the on-site operators, and the labor intensity of the operators is relatively high;

[0008] (2) High cost: Missing detection has brought irreparable losses to the manufacturer; at the same time, with the rise of labor costs, the demand for automatic detection is also increasing;

[0009] (3) High missed inspection rate: due to factors such as operator fatigue and technical quality, missed inspections and other problems often occur;

[0010] (4) Low detection accuracy: when the speed of the production line reaches more than 300 meters using dual technology and other detection technologies, software calculations will cause problems such as frame loss, which will affect the detection accuracy
