China's agricultural drones, like those from EAVision and DJI, heavily utilize binocular vision systems for advanced perception, enabling autonomous navigation, obstacle avoidance (even in complex terrain like mountains), and precise spraying without pre-mapping, allowing for day/night operation, effective canopy penetration (trees/crops), and improved efficiency with features like dual-atomized nozzles and radar integration. These intelligent systems offer real-time reaction, precise droplet control, and can adapt to varied farming needs, boosting yields and sustainability.
