Abstract
This application pertains to the field of encoding and decoding technologies, and discloses a point cloud encoding method and apparatus, a point cloud decoding method and apparatus, and an electronic device. The point cloud encoding method in embodiments of this application includes: obtaining, by an encoder, a to-be-encoded node in a point cloud sequence and m encoded reference nodes in the point cloud sequence, where m is a positive integer; determining, by the encoder, a context of a to-be-encoded subnode based on occupancy information of the m reference nodes and a position of the to-be-encoded subnode in the to-be-encoded node, where the to-be-encoded subnode is any subnode obtained by partitioning the to-be-encoded node based on a structure tree; and performing, by the encoder, entropy encoding on the to-be-encoded subnode based on the context to generate a target bit stream.
