基于机器视觉的工业屏幕缺陷检测系统设计

In the production of industrial electronic screens, due to the influence of industrial shooting equipment, there are often defects such as point defects, line defects, mass defects and light leakage defects, so the detection of defects on the production line is an important part of the production. At present, many production lines still use the way of manual observation, the results depend on manual experience, judgment is unstable, and waste of human and material costs. In the detection system, the preprocessing of screen data is the key of the detection system, which directly determines the effect of system flaw detection. Therefore, based on the digital image processing algorithm, this paper studies the image preprocessing module of the screen detection system, which can effectively obtain the screen area of interest and suppress the background influence, enhance the contrast between defects and background, and effectively improve the detection performance and efficiency.
