Abstract:
A method is provided. The method includes: generating a tracking plane image of a next video frame by using reference polar coordinates of a central position of a play plane image of a current video frame as a center based on a panoramic image of the next video frame in a spherical polar coordinate system; determining updated polar coordinates of a central position of a target object in the tracking plane image of the next video frame in the spherical polar coordinate system based on an object feature of the target object; and using the updated polar coordinates as the reference polar coordinates to re-perform the generating a tracking plane image of a next video frame by using reference polar coordinates as a center based on a panoramic image of the next video frame in a spherical polar coordinate system.
