Abstract

This application discloses a three-dimensional mesh inter-frame prediction encoding method, decoding method, and apparatus, and an electronic device, and belongs to the field of three-dimensional dynamic mesh encoding and decoding technologies. The encoding method in embodiments of this application includes: performing, by an encoder side, first processing on a to-be-encoded three-dimensional mesh, to obtain a basemesh; performing, by the encoder side, submesh division on the basemesh, to obtain a P submesh; determining, by the encoder side, a target encoding mode of a to-be-encoded mesh vertex in the P submesh and a first target motion vector prediction MVP value, where the first target MVP value is one of N MVP values included in a first candidate list, each MVP value in the first candidate list corresponds to one index, and N is an integer greater than 1; and encoding, by the encoder side, the target encoding mode and an index corresponding to the first target MVP value, to obtain a bitstream including first information, where the first information is used to indicate the target encoding mode and the index corresponding to the first target MVP value.
