Embodiment 1

[0028] Such as figure 1 As shown, a UAV flight control method provided in the embodiment of the present application, the UAV is equipped with a distance sensor, the method includes:

[0029] Step 110: The UAV obtains a first distance from the UAV to the obstacle through the distance sensor.

[0030] Specifically, the drone has a distance sensor, and the distance sensor may be an infrared distance sensor, an ultrasonic distance sensor, a laser distance sensor, or the like. The application does not specifically limit the type of the distance sensor. The above-mentioned distance sensor is arranged on the UAV, and its main function is to monitor the real-time distance between the UAV and the obstacle, and obtain the first distance between the UAV and the obstacle according to the distance sensor. When the UAV is in the flight state, the flight state can be the flight state in the case of performing a variety of different tasks, for example: map surveying, forest survey, emergenc...

Embodiment 2

[0045] The embodiment of the present application also provides a UAV flight control device, the UAV includes a distance sensor, wherein the device includes:

[0046] A first obtaining unit 11, the first obtaining unit 11 is used for the UAV to obtain a first distance from the UAV to obstacles through the distance sensor;

[0047] The first execution unit 12, the first execution unit 12 is used to execute the first shutdown instruction of the UAV when the first distance reaches a predetermined distance, wherein the first shutdown instruction is the unmanned The machine stops at the first speed;

[0048] The second obtaining unit 13, the second obtaining unit 13 is used for the distance sensor to obtain the moving second distance of the obstacle during the shutdown process of the UAV according to the first shutdown instruction;

[0049] The second execution unit 14, the second execution unit 14 is used to execute the second shutdown instruction of the drone according to the sec...

Abstract

The invention provides an unmanned aerial vehicle flight control method and device, and relates to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle comprises a distance sensor. The method comprises the steps that the unmanned aerial vehicle acquires the first distance from the unmanned aerial vehicle to an obstacle through the distance sensor; when the first distance reaches the preset distance, the unmanned aerial vehicle performs a first stop instruction, wherein the first stop instruction refers that the unmanned aerial vehicle stops according to first speed; when the unmanned aerial vehicle stops according to the first stop instruction, the distance sensor acquires the second distance moved by the obstacle; and the unmanned aerial vehicle performs a second stop instruction according to the second distance, wherein the second stop instruction refers that the unmanned aerial vehicle stops according to second speed. The problems in the prior art that the unmanned aerial vehicle encounters the moving obstacle in the flight and the instruction performed by the unmanned aerial vehicle cannot be adjusted and then the operation performed by the unmanned aerial vehicle is unsuitable and thus the unmanned aerial vehicle collides with the obstacle and has other risk can be solved by the unmanned aerial vehicle flight control method and device.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a flight control method and device for an unmanned aerial vehicle. Background technique [0002] At present, drones are widely used in map surveying, forest surveying, emergency rescue, logistics express, high-altitude photography and other fields. [0003] With the development of drone technology, in order to ensure the safety of drones or operators in the prior art, a security mechanism for drones is set to ensure the safety of drones or operators. For example, when the drone encounters an obstacle during flight, the drone is operated so that it does not collide with the obstacle. [0004] But, the inventor finds that there are following deficiencies in the prior art in daily work: [0005] The obstacles encountered by the UAV during the flight are often moving. When the obstacle moves, although the UAV will obtain the distance between the UAV and the obstacl...
