[0002] Visual inspection is to use machines instead of human eyes to make measurements and judgments. Visual inspection refers to the use of machine vision products (i.e. image capture devices, which are divided into CMOS and CCD) to convert the captured target into image signals, which are transmitted to a dedicated image processing system and converted into digital signals based on pixel distribution, brightness, color and other information. 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 based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging, and it has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.
