Abstract
A method and a device for measuring flight parameters of an unmanned aerial vehicle (UAV) are provided, the method includes, capturing images and collecting an angular velocity of the UAC, extracting corner points from a current frame image, estimating an estimated area according to the angular velocity of the UAV, searching for a corresponding corner point in the estimated area, obtaining a speed of each of the corner points, obtaining a pixel velocity, and obtaining an actual speed of the UAV based on the pixel velocity and a flight altitude of the UAV.
