Abstract

The invention provides a smart card stain detecting system based on image feature matching technology and detection and a detecting method, wherein the detecting system comprises a collection camera, a lighting light source, a background light source and an adsorption transmission platform, wherein the collection camera is arranged above a detected card surface, the lighting light source is arranged between the collection camera and the detected card surface, and the lighting light source and the collection camera are arranged coaxially, the background light source is arranged below the detected card surface, the detected card surface is placed on the adsorption transmission platform; the detecting system further comprises a controller connected with the lighting light source and the background light source to adjust luminance of light source, and a processing unit connected with the collection camera and the adsorption transmission platform, for processing the images collected by the collection camera and outputting a control signal to the adsorption transmission platform.

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...
