The automatic filling scale uses the computer to realize the human vision function, the machine replaces the human eye to measure and judge, the Filling system uses the photoelectric imaging system to collect the image of the controlled target, the computer or a dedicated image processing module for digital processing, according to the image pixel distribution, brightness and color information, size, shape, color, etc. In this way, the speed and repeatability of the computer are organically combined with the high intelligence and abstract ability of human vision, and the large automatic Filling machine greatly improves the flexibility and automation of the production process detection, saves a lot of manpower, improves the inspection efficiency and ensures product quality.

Automatic filling machine vision technology includes light source lighting technology, optical imaging technology, sensor technology, digital image processing technology, mechanical engineering technology, detection and control technology, analog and digital video technology, computer technology, human-machine interface technology and other related technologies, is the basic technology to achieve computer integrated system. Therefore, the machine vision technology is applied to the online detection of chemical packaging drum quality, label, solution loading, packaging batch number, etc., in order to achieve rapid and automatic detection and control of drug production.
