Abstract
In order to improve the autonomous operation ability and effectiveness of plant protection drones in obstacle environments, and meet the requirements of autonomous spraying, real-time obstacle avoidance, and precise operation of plant protection drones, this paper conducts relevant research from two aspects: obstacle avoidance and increasing the coverage of fog droplets around obstacles when avoiding obstacles. Aiming at obstacle avoidance of plant protection UAVs, it mainly involves research on field obstacle information recognition, obstacle avoidance algorithm improvement, obstacle avoidance system and flight platform design and construction; In order to increase the coverage of fog droplets around obstacles during obstacle avoidance and detour, the research on side spraying technology of plant protection drones is mainly carried out. The human-computer interaction interface is simplified and emotional designed to improve user comfort. The appearance of the plant protection UAV is designed with beautiful bionic seven-star ladybug shape, simple and easy-to-use human-computer interaction interface, solar endurance and retractable rotor, and it is equipped with high-definition camera and infrared detector to remotely collect field information. It has changed the shortcomings of the common plant protection UAV design, such as dull appearance, poor human-computer interaction, difficult operation, and single function. At the same time, the plant protection UAV designed by bionic appearance has not only powerful practical functions, but also more profound artistic spirit and value connotation through emotional communication with users on social, cultural and spiritual levels.
