Problems solved by technology

[0006] However, when encoding and compressing the panoramic video, since the panoramic image is a curved surface image, when it is mapped to a two-dimensional plane for encoding, in order to preserve the complete information of the curved image, there will usually be some stretching and distortion, so that the objects in the panoramic video The motion is not necessarily rigid motion, and the GMV information calculated by this is not necessarily accurate, thus reducing the quality of video coding

Abstract

Disclosed are an image processing method and device. The method comprises: determining at least one second region for obtaining a first region on a first planar image, the second region being a regionon a second planar image, and the first planar image being obtained by mapping of a curved surface image, the curved surface image being obtained from at least one second planar image; determining amotion vector of the first region using a motion vector of the at least one second region; and encoding the first planar image using the motion vector of the at least one first region included in thefirst planar image. According to the technical solution of embodiments of the present application, more accurate vector information can be obtained, thereby enhancing video encoding quality.
