The traditional surface quality inspection of hardware and electronic products adopts the method of manual inspection by the quality inspector. However, these manual methods have the disadvantages of low sampling rate, low accuracy, poor real-time performance, low efficiency and high labor intensity, and the automatic surface detection method based on machine vision can overcome these disadvantages to a large extent.

At present, the application of machine vision technology, that is, the addition of vision systems on machines or automated production lines, has become an indispensable technical means of quality control in the electronics manufacturing industry. The surface inspection system based on machine vision mainly consists of two processes: image acquisition and defect detection. The image acquisition module consists of an industrial camera, an optical lens, a light source and a clamping device. The function of the image acquisition module is to collect the surface image of the target product, and the defect detection process is to identify the defect through image processing and classification technology according to the acquired image.
