Embodiment 1

[0033] When the UAV is in the vertical flight mode, if the flight attitude changes, the sensing direction of the distance sensor will also change with the flight attitude, which will easily lead to unsafe flight. For example, when the UAV adopts the flight action of oblique flight, since the distance sensor will also tilt the sensing direction with the oblique flight of the UAV, the above-mentioned oblique flight action of the distance sensor makes the vertical direction measured by the distance sensor Errors occur in the distance of obstacles, which reduces flight safety.

[0034] Such as figure 1 As shown, this embodiment provides a flow chart of a UAV flight control method, wherein the UAV includes a distance sensor, and the method includes:

[0035] Step 110: Obtain the vertical flight attitude of the drone;

[0036]Specifically, the vertical flight attitude of the UAV is the flight attitude in which the fuselage of the UAV is perpendicular to the flight direction. Gene...

[0079] Such as image 3 As shown, the embodiment of the present application also provides a UAV flight control device, the UAV includes a distance sensor, wherein the device includes:

[0080] A first obtaining unit 11, the first obtaining unit 11 is used to obtain the vertical flight attitude of the drone;

[0081] A second obtaining unit 12, the second obtaining unit 12 is used to obtain the first flight attitude of the drone;

[0082] A first adjustment unit 13, the first adjustment unit 13 is configured to adjust the second parameter information of the distance sensor according to the first parameter information between the first flight attitude and the vertical flight attitude, so that the The distance sensor is a vertical sensing direction.

[0083] Further, the device also includes:

[0084] a third obtaining unit, the third obtaining unit is used to obtain the first flight direction of the UAV;

[0085] A first determining unit, the first determining unit is config...

Abstract

The embodiment of the invention provides a flight control method for an unmanned aerial vehicle and relates to the field of aeronautical technology. According to the embodiment of the application, the method comprises the following steps of: obtaining a first flight attitude of an unmanned aerial vehicle by obtaining the vertical flight attitude of the unmanned aerial vehicle; and adjusting the second parameter information of a distance sensor based on the first parameter information between the first flight attitude and the vertical flight attitude, so that the distance sensor is a in a vertical sensing direction. Through the above technical scheme, the actual distance of the unmanned aerial vehicle from an obstacle can be effectively obtained and is in line with the distance sensed by the distance sensor, so as to effectively avoid the collision of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a method and device for controlling the flight of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. [0003] At present, with the continuous development of drone technology, drones are used more and more widely. Because drones have the advantages of no risk of casualties, strong survivability, good maneuverability, and convenient use, they have been widely used in Mapping, forest surveying, emergency rescue, logistics express, high-altitude photography and other fields. [0004] In the current drone control, the use of distance sensors equipped with drones, such as infrared distance sensors, ultrasonic sensors, etc., makes the application scenarios of drones more extensive, and the operation is more convenient and safer.
