Abstract
The present invention relates to the technical field of encoding and decoding. Disclosed are a three-dimensional mesh encoding method and apparatus, and a three-dimensional mesh decoding method and apparatus. The three-dimensional mesh encoding method comprises: acquiring a reference mesh and division of the reference mesh, and on the basis of the division of the reference mesh, dividing the reference mesh into at least one sub-reference mesh; acquiring a mesh to be encoded and division of the mesh to be encoded, and on the basis of the division of the mesh to be encoded, dividing the mesh to be encoded into at least one sub-mesh to be encoded; and determining whether information of all or part of the sub-reference mesh is used to encode the sub-mesh to be encoded. The present invention can provide more accurate encoding and decoding methods.
