Abstract
An inter prediction method includes parsing, by a processor, a bitstream to obtain a location of a target adjacent image block of a current image block. The method further includes obtaining a preset correspondence between an adjacent image block location and a motion vector precision, wherein in the preset correspondence, locations of at least two adjacent image blocks correspond to different motion vector precisions. The method further includes determining, based on the location of the target adjacent image block and the preset correspondence, a target motion vector precision corresponding to the target adjacent image block. The method further includes determining a motion vector predictor of the current image block based on the location of the target adjacent image block and the target motion vector precision.
