Research Progress and Prospects of Obstacle Avoidance Technologies for Agricultural Unmanned Aerial Vehicles

With the rapid development of precision agriculture and smart agriculture, agricultural drones have demonstrated significant potential for application in the agricultural sector due to their efficiency and flexibility. However, agricultural drones face multiple challenges in practical operations, including complex environment perception, intricate data processing, and high-precision positioning, which limit the conversion of their potential into actual productivity. Therefore, the research and development of obstacle avoidance technology for agricultural drones is crucial. This study analyzes the current research progress in obstacle avoidance technology for agricultural drones, focusing on the application, advantages, and disadvantages of sensor technology in obstacle detection, innovations in environmental modeling technology to improve the accuracy of environmental understanding. The study also anticipates the development trends of obstacle avoidance technology for agricultural drones, suggesting that future research will concentrate on various combined obstacle avoidance forms to enhance the accuracy and robustness of obstacle avoidance, real-time active obstacle avoidance technology to adapt to more complex farmland environments, the development of obstacle avoidance assistance systems to improve user operating experience and work efficiency, and the standardization of obstacle avoidance processes to promote the standardization and industrialization of the technology.
