Title:
METHOD AND DEVICE FOR DETECTING FLIGHT ALTITUDE, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/058288
Kind Code:
A1
Abstract:
A method and device for detecting flight altitude, and an unmanned aerial vehicle (100). The method comprises: acquiring a flight speed of an unmanned aerial vehicle (100) (S101); calculating, according to the flight speed, a compensation value for an atmospheric pressure measurement (S102); correcting the atmospheric pressure measurement according to the compensation value (S103); and determining, by referring to the corrected atmospheric pressure measurement, a flight altitude of the unmanned aerial vehicle (100) (S104). The present invention corrects, by referring to a positive correlation between a negative pressure within a body provided with a barometer and the flight speed of the unmanned aerial vehicle (100), and by using the flight speed of the unmanned aerial vehicle (100), the atmospheric pressure measurement measured by the barometer. The corrected atmospheric pressure measurement has high accuracy, and prevents a measured flight altitude of the unmanned aerial vehicle (100) from exceeding an actual altitude of the unmanned aerial vehicle (100), thereby preventing loss of flight altitude of the unmanned aerial vehicle (100).
