The invention relates to a method for guiding a flight device to track a target. The flight device tracks the target in a tracking mode that the flight device performs circumferential flight on a circular expected flight path around the target; the method comprises the following steps: guiding the flight device to fly from the first position to the direction close to the target through the first instruction; wherein the distance from the first position to the target is greater than or equal to a first threshold; monitoring the distance between the flight device and the target; guiding the flight device to fly at a preset yaw rate through a second instruction in response to that the distance is smaller than a first threshold value; in response to that the distance is less than or equal to asecond threshold, monitoring a first angle between the first direction and the second direction, wherein the first direction is the horizontal speed direction of the flight device, and the second direction is the tangential direction of the intersection point of the connecting line of the unmanned aerial vehicle and the target on the circular expected track; and guiding the flight device to enterthe circular expected track through a third instruction in response to the fact that the first angle is smaller than or equal to an angle threshold or the distance is smaller than or equal to a thirdthreshold.
Description
technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a method for guiding a flying device to track a target, a computer system and a medium. Background technique [0002] With the rapid development of artificial intelligence, automatic control, communication and computer technology, drones are increasingly used in many fields such as industrial and agricultural production, construction, logistics, and daily life. [0003] The tracking of fixed or moving targets is one of the important combat tasks of UAVs. For example, the target can be tracked by a tracking mode in which the UAV keeps a specified distance from the target and flies around the target on a circular expected track at a certain speed and altitude. [0004] However, in the process of implementing the concept of the present invention, the inventors found that there are at least the following problems in the prior art: the efficiency of the UAV converging ...
