Abstract: In order to improve the recycling precision and recycling rate of unmanned aerial vehicles (UAV) in complex environment, a precise recycling method of UAV based on laser terminal guidance was adopted. The principle and process of precise UAV recycling by means of laser terminal guidance were analyzed and verified. The relationship between the guide distance of UAV and laser guidance light radiation field and the relationship between yaw angle information of UAV departure and system precise recycling were discussed. The results show that in the range of rough guide distance of 1km to 2km from the landing point, keeping a constant laser guided field of 40m, the UAV can quickly enter the laser radiation field, adjust yaw angle information and improve the reliability of recycling. In the range of middle distance, the relationship between laser radiation field and landing distance changes linearly, which is beneficial for transferring from the rough guidance to the precise guidance. In the range of precise guide distance within 500m and constant laser guided field of 20m, the system can improve the precision of recycling. The scheme is applied to UAV recycling system, which can significantly improve the recycling precision of UAV in complex environment.
