Embodiment Construction
[0025] Certain terms are used throughout the description and claims to refer to particular components. It should be understood by those skilled in the art that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] figure 1 It is a structural schematic diagram of the control device of the unmanned aerial vehicle according to the embodiment of the present invention. Such as figure 1 As shown, the device includes: a first acquisition module 10 , a second acquisition module 20 , a judging module 30 and a control module 40 .
[0027] The first acquisition module 10 is used to acquire the first distance information between the UAV in the current state along the ver...

The invention discloses a control method and device for an unmanned aerial vehicle. The control method comprises the steps that information of a first distance between an obstacle arranged above the unmanned aerial vehicle and the unmanned aerial vehicle in the current state in the vertically-upward direction and information of a second distance between an obstacle arranged below the unmanned aerial vehicle and the unmanned aerial vehicle in the current state in the vertically-downward direction are obtained; whether a ratio of the information of the first distance to the information of the second distance meets a preset condition or not is judged; if the ratio of the information of the first distance to the information of the second distance does not meet the preset condition, the flight height of the unmanned aerial vehicle is adjusted, so that the ratio of the information of the first distance to the information of the second distance obtained after the flight height is adjusted meets the preset condition. By the adoption of the mode, the flight height of the unmanned aerial vehicle can be controlled only according to the information of the first distance and the information of the second distance, and the control method is simple and easy to implement; meanwhile, the phenomenon that the unmanned aerial vehicle collides with the obstacle arranged above the unmanned aerial vehicle or the obstacle arranged below the unmanned aerial vehicle in the flight process can be avoided, and the flight capacity of the unmanned aerial vehicle in a complex environment is further improved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a control method and device for an unmanned aerial vehicle. Background technique [0002] An unmanned aerial vehicle is an unmanned aerial vehicle mainly controlled by radio remote control or its own program. When the UAV is flying freely, it is necessary to control the flying height of the UAV to prevent the UAV from colliding with obstacles in the vertical direction. [0003] An existing method for controlling the flying height of the unmanned aerial vehicle is: acquiring the flying height of the unmanned aerial vehicle from the ground by adding a sensor at the bottom of the aircraft. The disadvantage is that in actual situations, when the flying environment of the aircraft is relatively complicated, such as when there are obstacles above the aircraft, the aircraft cannot detect the obstacles above, which may cause the aircraft to collide with the obstacles. ...
