In traditional industrial production and processing, due to the constraints of scientific skills, manual inspection is still the primary choice to check the appearance of the product. This method, due to the constraints of manual labor and skills falling behind, not only slow and inefficient inspection of the product, but also makes mistakes in the inspection process, resulting in inaccurate inspection.

In today's society, with the emergence and development of scientific skills such as computers and artificial intelligence, and the deepening of considerations, there has been a product appearance inspection based on visual technology. The emergence of this technology has greatly improved the efficiency of production operations. Fortunately, due to the operating environment, one-sided speculation, and other factors that affect the accuracy of the inspection, it is possible to better inspect the appearance defects and quickly identify the defects of the product.

Appearance inspection belongs to a type of visual technology that uses computer vision to imitate the effectiveness of human vision, and conducts practical observation and application of image collection, processing, and accounting from specific objects. The inspection of the appearance defects of the product is a crucial aspect of visual inspection, as the correct level of inspection will directly affect the quality of the product. Given that the use of manual inspection methods is no longer satisfactory for the production and improvisation of inventions, and the use of machine vision inspection has effectively overcome this, the widespread use of appearance defect inspection systems has encouraged high-quality production in factories and the development of intelligent automation in the invention industry.

Product appearance inspection is a major highlight of Tongguang Technology's inspection products. Generally, everything can be inspected. If you want to test the appearance defects of a trial product, the material appearance includes moving objects, precipitates, frosting, discoloration, foreign objects, pollutants, etc., while the unknown objects include powder, liquid, particles, etc. However, other inspections require other instruments: component testing generally involves detecting the components of a product, relying on the qualitative and quantitative (or quantitative) analysis and testing skills of chemical materials to accurately determine the various components, elemental content, and filler content of the material.

The product is subjected to various differentiation methods, scientifically analyzed through qualitative and quantitative analysis instruments, and then analyzed through reverse thinking to complete the process of qualitative and quantitative differentiation of sample components. In this process, in addition to relying on advanced equipment support, the skilled personnel must also possess abundant operational and theoretical knowledge.
