Abstract

A dynamic range mapping method and apparatus for a panoramic video that relate to the field of video image processing are provided. The method includes: splitting a two-dimensional panoramic projection image corresponding to any frame of three-dimensional panoramic image in a panoramic video, to obtain a plurality of regions of the two-dimensional panoramic projection image; obtaining metadata of the two-dimensional panoramic projection image, where the metadata includes metadata information elements separately corresponding to the plurality of regions, and a metadata information element corresponding to one region includes dynamic mapping information of the region; determining dynamic mapping information of each pixel in a current angle of view range based on respective dynamic mapping information of the plurality of regions; and performing dynamic range mapping on each pixel in the current angle of view range, to obtain a two-dimensional panoramic projection image that is used for display or subsequent processing.
