Description

technical field [0001] The invention belongs to the field of optical detection of printed matter, and relates to a smart card stain detection system and an implementation method based on image feature matching technology. Background technique [0002] With the rapid development of the application of vision and image processing technology, image-based detection technology has been widely used in many fields such as industrial inspection, visual measurement and industrial automation. [0003] There are many processes in the printing and card making process, and the production is highly automated. However, in the finished product inspection process, domestic manufacturers still mainly use manual inspection to test the quality of the printing process for the product. Determine the presence and cause of stains and damage. For example, due to various reasons such as degreasing, lamination, hair dust, printing offset, poor magnetic stripe, etc., stains and damages on the surface o...
