The work aims to design a set of instant noodle packaging quality detection system based on machine vision to solve the problems of fatigue and instability caused by manual detection, and improve the efficiency of online testing of package quality. The overall design scheme of the instant noodle packaging quality detection system was given, and the hardware design structure and the software design flow were described; besides, the principle and process of machine-vision detection system were analyzed. The results showed that the instant noodle packaging quality detection system using machine vision had a higher recognition rate of the production process. The detection system has low detection rate, low misdetection rate and high detection efficiency, which can meet the production demand.
