Abstract
The present invention is applicable to the field of videos, and provides a panoramic video anti-shake method and a portable terminal. The method comprises: obtaining world coordinates of any reference point in a world coordinate system in real time, and simultaneously obtaining camera coordinates corresponding to the reference point in the portable terminal and an angular velocity value of a current state of a gyroscope in the portable terminal; smoothing the motion of a camera using an extended Kalman filter; decomposing the smoothed motion to synthesize virtual lens motion of a free lens mode, and calculating the rotation amount of the virtual lens; and re-projecting an original video to generate a stable video.
