[0002] In the field of industrial manufacturing, plating parts are widely used, from daily necessities to precision mechanical parts. The surface quality of plating parts directly affects product performance and appearance.

In severe cases, it may even cause the product to be unable to use normally, so plating part surface defect detection is very important.

[0003] Traditional plating part surface defect detection mainly relies on manual visual inspection or simple automated optical detection equipment. Although manual detection can be adjusted flexibly for different products, it is low in efficiency and easily affected by subjective factors, making it difficult to ensure consistency and accuracy of detection. Early automated optical detection equipment can achieve a certain degree of automatic detection by scanning the workpiece with fixed optical sensors. This type of equipment usually includes a fixed-position camera or other optical sensor and corresponding image processing software to capture and analyze the surface image of the plating part and identify possible defects.
