Description

Technical Field

[0001] The invention relates to the technical field of printed glass visual inspection, and in particular to a printed glass visual defect inspection device. Background Art

[0002] Printed glass is a kind of glass surface coated with a layer of colorful fusible inorganic glaze through screen printing, inkjet printing and other technologies. After heating or tempering, it forms a stable and lasting color, acid and alkali resistant, translucent glazed glass. It is a decorative glass with patterns formed on the glass surface through a special process. Printing methods include screen printing, digital printing, etc. It is generally used in building facades: printed glass is often used in building facades, creating unique visual effects through different patterns and transparency changes; interior decoration: such as partitions, screens, doors and windows, etc., printed glass is favored for its unique artistry and decorativeness; commercial spaces: such as shopping malls, hotels and other places, printed glass can be used to create a specific atmosphere and brand image.

[0003] Visual inspection is an automated inspection method that uses machine vision technology for measurement and judgment. Visual inspection uses machines to replace human eyes for measurement and judgment. Through machine vision products, that is, image capture devices, which are divided into CMOS and CCD, the captured target is converted into an image signal and transmitted to a dedicated image processing system. According to pixel distribution, brightness, color and other information, it is converted into a digital signal; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on site according to the judgment results. The characteristics of visual inspection are to improve the flexibility and automation of production. In some dangerous working environments that are not suitable for manual operations or where manual vision cannot meet the requirements, machine vision is often used to replace manual vision; at the same time, In the process of mass industrial production, manual visual inspection of product quality is inefficient and not very accurate. The use of machine vision inspection methods can greatly improve production efficiency and the degree of automation of production. Typical structures include: lighting, lenses, cameras, image acquisition cards, and visual processors. In industrial production, visual inspection can be used to identify product appearance defects, dimensional deviations and other problems to improve product quality and production efficiency. In the medical field, visual inspection can be used for medical image analysis, disease diagnosis, etc., to assist doctors in more accurate diagnosis and treatment. In the field of security monitoring, visual inspection can be used for face recognition, behavior analysis, etc. to improve safety prevention capabilities. In the field of intelligent transportation, visual inspection can be used for traffic flow monitoring, license plate recognition, etc. to optimize traffic management and planning.
