Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The unmanned aerial vehicle flight control method and device provided by the present invention are used to control the unmanned aerial vehicle to take off and land on the preset platform, such as figure 1 and figure 2 As shown, the flying platform is provided with a supporter for taking off and landing of the unmanned aerial vehicle and for carrying the unmanned aerial vehicle, and is also equipped with a geographic location coordinate transmitter. Users can set up one or more platforms on the ground for selective landing and takeoff of UAVs. In the present invention, the geographic location coordinate information sent by the geographic location coordinate transmitter is collected by the receiver of the unmanned aerial vehicle, and the information containing the guide mark used by the platform to guide the un...

Abstract

The invention discloses a flight control method for an unmanned aerial vehicle. The method includes the first step of collecting coordinate information transmitted by a platform for landing and taking-off of the unmanned aerial vehicle, the second step of targeting the landing platform according to the collected coordinate information, the third step of controlling the unmanned aerial vehicle to fly to the place near the targeted platform and then collecting image information of guiding marks, used for guiding the unmanned aerial vehicle to land at the position and orientation on the platform, of the platform, and the fourth step of controlling the unmanned aerial vehicle to land onto a supporting device prearranged on the platform according to the guiding marks and distance information detected by a prearranged distance sensor. The invention further discloses an unmanned aerial vehicle control device. Through the flight control method and device for the unmanned aerial vehicle, the control accuracy of the unmanned aerial vehicle is improved, the weight of the unmanned aerial vehicle is reduced, and the flight time is prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aircraft control, in particular to a flight control method and device for an unmanned aircraft. Background technique [0002] As we all know, unmanned aerial vehicles in the prior art usually use six-axis gyroscopes and flight controllers to achieve attitude-stabilized flight, and use satellite positioning systems (such as GPS), compass and barometer sensor information to assist in inertial navigation and autonomous positioning. Take off, land. The six-axis gyroscope includes a three-axis gyroscope and a three-axis accelerometer, which can provide acceleration and angular velocity information of the corresponding axis; a satellite positioning system (such as GPS) receiver can provide the current three-dimensional position coordinates and flight speed of the aircraft, and the compass can be used for Auxiliary to correct the flight direction, the barometer can provide the relative altitude of the ...
