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 5):
The panoramic video processing method according to  claim 4 , wherein, the 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 includes\n calculating, based on the historical motion trajectory, a motion noise value of the current 2D panoramic image relative to the previous 2D panoramic image; and determining, if the motion noise value is less than or equal to a predetermined threshold, that the change is unconscious noise motion including unconscious noise motion within a predetermined noise tolerance range and unconscious noise motion exceeding the predetermined noise tolerance range, and if the motion noise value is greater than the predetermined threshold, that the change is conscious camera motion, the predetermined noise tolerance range being less than or equal to another threshold which is less than the predetermined threshold.
