Computer vision technology plays an important role and becomes one of key technologies in the intelligent automation of food processing because of its outstanding advantages, such as its high speed of detection, contactless nature, and high precision. In recent years, both theoretical methods and practical technologies in the field of computer vision have been developed rapidly. In this paper, the research achievements and successful applications of computer vision technologies in food industry are reviewed, including some key topics, such as process monitoring, quality supervision and food safety. Moreover, the authors elucidate the significance of computer vision technologies in the intelligent optimizing controls and the cooperation and coordination of networked multi-robot food processing systems for the intelligent automation of food industry. Finally, the prospect and development trends of computer vision technologies for food processing are discussed.
