Abstract

The invention relates to the technical field of flight control, in particular to a target tracking method and device and an aircraft. The method includes the steps of receiving GPS information of a tracking target, calculating a first speed and a first direction of the tracking target according to the GPS information, estimating a target position of the tracking target at the next time point according to the first speed and the first direction, obtaining a second speed and a second direction of the aircraft according to the first speed and the first direction, and controlling the aircraft to fly to the target position according to the second speed and the second direction to achieve target tracking. The target tracking method has a good tracking effect.

Description

technical field [0001] The present invention relates to the technical field of flight control, in particular to a target tracking method, device and aircraft. Background technique [0002] The commonly used method of drone follow-up shooting is based on GPS tracking, that is, the GPS information of the aircraft is compared with the GPS information of the target. The aircraft maintains a position relative to the GPS on the ground, and uses the camera to aim at the target. The angle of the camera is the angle calculated from the height of the ground to the target distance, and the direction of the nose is the angle between the coordinate relationship between the aircraft point and the target point, so that the tracking target can be tracked and photographed using GPS. However, because the GPS update frequency is relatively slow and there is a certain delay, the following UAV responds slowly when the target changes its running direction, and it is difficult to point the camera ...
