This technology uses a small drone as a carrier, carrying a camera to manually manipulate and shoot, and sends the image back to the cloud to identify the litchi stink bugs of different ages. Finally, the results and positioning are sent back to the mobile APP and integrated into Google map for visualization Shows the places where the litchi stink bugs are common. Cooperate with the UAV to spray on the spot where litchi stink bugs occur, and fly according to different slopes, greatly improving the control efficiency and reducing the amount of pesticides.This technology integrates agricultural, engineering and other academic research units, integrates real-time image recognition, environmental sensing and other Internet of Things functions and establishes a UAV identification litchi stink bug occurrence system, introduces intelligent path planning, improves the efficiency of unmanned vehicle prevention and control, and achieves precise medication. Prevention target.This technology uses the UAV to identify the location and hazard degree of the litchi stink bug. Quantification of the hazard situation and the visualization of the distribution location are used as a reference for the effective prevention and operation of the prevention of the litchi stink bug. Using UAV with ceramics hollow cone nozzles carried appropriate pesticide dose, to establish a set of prevention strategies for litchi stink bug that can effectively control the litchi stink bug and achieve the goal of precise pesticide application. The strategies can be the standard of control litchi stink bugs on slop field for pesticide spraying service technicians, improve the overall control efficiency, also solve the problem of unmanned management of orchard.
