Embodiment 1

[0039] figure 1 It is a schematic flowchart of an embodiment of the UAV automatic tracking method of the present invention.

[0040] In step S100, taking the position of the target in the N-1th frame image as the reference position, extracting the features of the image within a predetermined range near the reference position of the Nth frame image, where N is greater than or equal to 2 A natural number; in step S110, calculate the response value between the target and the images within the predetermined range and use the maximum response value as the new position of the target.

[0041] For example, extract the features of the sub-window image near the target frame of the next frame image, and detect the maximum classifier response value, and use the position of the maximum response value as the tracking result. More specifically, the position of the target in the previous frame image is used as the reference position, and a predetermined ratio (for example, 1.5 times) is exp...

Abstract

The invention discloses a UAV automatic tracking method, a UAV automatic tracking device and a UAV. The UAV automatic tracking method includes the steps of extracting, by using the position of a target in the N-1 frame image as a reference position, features of images within a predetermined range near the reference position of the N-th frame image, N being a natural number greater than or equal to2; calculating response values of the target and the images within the predetermined range and taking the maximum response value as a new position of the target; calculating the distance dN between the target and a camera based on the corrected position after the new position is corrected; and adjusting the attitude of a UAV according to the difference between the distance dN and the distance dN-1 from the target at the N-1-th frame to the camera. The technical scheme of the invention can also stably follow the target without a mechanical pan-tilt and can be used for target tracking in various outdoor complex environments.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an automatic tracking method for an unmanned aerial vehicle, an automatic tracking device for an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] With the rapid development of drone technology, various functions of drones have gradually been developed. Target tracking technology is applied to some drones, which can realize the tracking and shooting of targets by drones. The main principle of target tracking technology is to realize the detection of the target position by identifying the target. The drone can then track the target based on changes in its location to take the shot. [0003] The current mainstream UAVs with follow-up function basically use mechanical gimbals and target detection algorithms to follow. Shaking will cause rapid shaking of the image, and the target is easily lost, so the following function of the drone is a...
