Description

technical field [0001] The invention relates to the fields of unmanned aerial vehicle system application, photoelectric stabilization, image processing, photogrammetry, and telemetry data processing, and in particular to an unmanned aerial vehicle system and method for dynamic positioning of ground moving targets. Background technique [0002] During the use of drones, image reconnaissance is the main focus. With the need for target positioning, such as guiding fighter jets or missiles for fire strikes, correcting artillery targeting parameters, etc., UAVs begin to have target positioning capabilities. [0003] In the prior art, the realization method of target positioning is as follows: the wireless link receives the spatial position of the drone and the camera parameters of the optical axis stabilization platform, and after "freezing" the reconnaissance image at a certain moment, the target positioning calculation and the turret Whether the servo mechanism is still tracki...

Problems solved by technology

Although this method can describe the information in the field of view at the same time in a relatively large degree, but because multiple targets do not move at the same time or in the same direction in practical applications, there is a large lag in information acquisition in this method

[0007] In addition, there are other methods that are only at the theoretical stage, such as the target positioning method based on image matching, which has high accuracy but poor practicality, and has not yet been engineered; the positioning method of dual UAVs under the constraint of communication distance and the rendezvous of two points in space are unmanned. Machine positioning method, the principle is simple, the error introduces fewer elements, but it lacks operability

These methods are difficult to implement in engineering, and in the actual application process, they cannot locate moving targets on the ground in real time, and the calculation accuracy of fixed target positions is not high, and they cannot realize dynamic positioning and target behavior prediction.
