Document Type and Number:
WIPO Patent Application WO/2018/141198
Kind Code:
A1
Abstract:
A method and a device for detecting the flight altitude of an unmanned aerial vehicle, and an unmanned aerial vehicle. The method for detecting the flight altitude of an unmanned aerial vehicle comprises: determining, on the basis of a second flight altitude detected by an ultrasonic altitude measuring device, the confidence of the detection using the ultrasonic altitude measuring device (103); and determining the flight altitude according to the confidence, a first flight altitude detected by an air pressure altitude measuring device, and the second flight altitude (104). The method and the device for detecting the flight altitude of an unmanned aerial vehicle and the unmanned aerial vehicle obtain the confidence of using the ultrasonic altitude measuring device by means of the flight altitude detected by the ultrasonic altitude measuring device, and perform fusion calculation of the confidence and the flight altitudes detected by the air pressure altitude measuring device and the ultrasonic altitude measuring device so as to generate a smooth fusion altitude value, making full use of the advantages of the ultrasonic altitude measurement and the air pressure altitude measurement, such that the problem of the discontinuity of flight altitude detection values in the existing fusion calculation can be solved, avoiding sudden changes in flight altitude detection values, improving the accuracy of the flight altitude measurement, and improving the stability of the control of the unmanned aerial vehicle.
