Flight device and flight control method
A flight device and a flight control method are disclosed. The method includes: acquiring an image and a height of the flight device; determining a scene in which the flight device is currently located; calculating an image X-offset and an image Y-offset of a second image frame of two adjacent image...

| description | A flight device and a flight control method are disclosed. The method includes: acquiring an image and a height of the flight device; determining a scene in which the flight device is currently located; calculating an image X-offset and an image Y-offset of a second image frame of two adjacent image frames relative to a first image frame of the two adjacent image frames; compensating for the image X-offset and the image Y-offset according to the acceleration and the angular velocity of the flight device to obtain image correction offsets comprising a corrected image X-offset and a corrected image Y-offset; calculating an X-offset and a Y-offset in world coordinates corresponding to the image correction offsets; and deriving a velocity of the flight device. |
