Abstract:
Panoramic video processing method and device are disclosed. The method includes steps of receiving a panoramic video waiting for processing; conducting inter frame motion estimation in regard to any two neighboring 2D panoramic images in the panoramic video so as to obtain an inter frame motion estimation result between the same two neighboring 2D panoramic images; acquiring, based on the respective inter frame motion estimation results, a historical motion trajectory of the panoramic video, and carrying out smoothing with respect to the historical motion trajectory; calculating, based on the historical motion trajectory after smoothing, a rotation matrix for motion compensation pertaining to each 2D panoramic image in the panoramic video; and performing reconstruction on each 2D panoramic image in the panoramic video by means of the corresponding rotation matrix for motion compensation so as to attain a panoramic video after image stabilization, and outputting the panoramic video after image stabilization.

Claim (Index 4):
The panoramic video processing method according to  claim 2 , wherein, the calculating, based on the historical motion trajectory after smoothing, a rotation matrix for motion compensation pertaining to each 2D panoramic image in the panoramic video; and performing reconstruction on each 2D panoramic image in the panoramic video by way of the corresponding rotation matrix for motion compensation so as to attain a panoramic video after image stabilization, and outputting the panoramic video after image stabilization includes\n determining, based on the historical motion trajectory after smoothing, that a change of a current 2D panoramic image relative to a previous 2D panoramic image is unconscious noise motion or conscious camera motion; calculating, if the change is unconscious noise motion, a rotation matrix for motion compensation of the current 2D panoramic image relative to the previous 2D panoramic image, and updating, if the change is conscious camera motion, a relevant reference 2D panoramic image, and computing, based on the relevant reference 2D panoramic image after update and the current 2D panoramic image, a rotation matrix for motion compensation between the relevant reference 2D panoramic image after update and the current 2D panoramic image; carrying out smoothing with respect to the rotation matrix for motion compensation; and applying the rotation matrix for motion compensation after smoothing to the current 2D panoramic image, so as to obtain a 2D panoramic image after image stabilization.
