The machine vision based farm intelligent inspection system is agricultural autonomous vehicle based and can complete the inspection task using machine vision under complex farm conditions. This system has the functions of data collection, video processing, object detection, data encapsulation, video transmission, and remote control. The system can evaluate crop growth and detect pests more efficiently than manual work. This Recommendation specifies requirements and functional architecture for machine vision based farm intelligent inspection system, and provides use cases. It is intended to guide the design and development of machine vision based farm intelligent inspection system.
