METHOD AND DEVICE FOR MEASURING FLIGHT PARAMETERS OF UNMANNED AIRCRAFT

摘要

A method and device for measuring flight parameters of an unmanned aircraft. The method comprises: acquiring an image and collecting an angular speed of an unmanned aircraft; extracting angular points from a current frame image; estimating a predetermined area of each angular point in a previous frame image in the current frame image according to the angular speed of the current unmanned aircraft; searching for a corresponding angular point from the predetermined area in the previous frame image according to an angular point position of the current frame image; acquiring an angular point speed according to the angular point of the current frame image and the angular point corresponding to the previous frame image; acquiring a pixel speed according to the angular point speed; and acquiring an actual speed of the unmanned aircraft according to the pixel speed and the flight height of the unmanned aircraft. By means of the above-mentioned method, the measurement of flight parameters with high precision and high accuracy can be realized.
