Method and device for controlling unmanned aerial vehicle to rotate along with face

The invention provides a method and device for controlling an unmanned aerial vehicle to rotate along with the face. A camera is arranged on the unmanned aerial vehicle. The method includes the steps that the face in an image is detected through a Viola-Jones face detection framework; the face is tracked, and two-dimensional coordinates of the five sense organs of the face in the image are determined; a three-dimensional face standard library is searched for three-dimensional coordinates of the five sense organs of the face in a world coordinate system; the three-dimensional face standard library is obtained in advance; three-dimensional coordinates of the face relative to the camera on the unmanned aerial vehicle are obtained according to the two-dimensional coordinates of the five sense organs of the face in the image and the three-dimensional coordinates of the five sense organs of the face in the world coordinate system; the unmanned aerial vehicle is controlled for position adjustment to enable the camera to be aligned with the face through the three-dimensional coordinates of the face relative to the camera of the unmanned aerial vehicle. When the unmanned aerial vehicle tracks a user to take pictures or record videos, the unmanned aerial vehicle can move along with rotation of the face, and it is guaranteed that a camera lens of the camera on the unmanned aerial vehicle is always aligned with the face of the user.
