SYSTEM AND METHOD FOR ENCODING AND DECODING THREE-DIMENSIONAL OBJECT DATA

摘要

PURPOSE: A system and method for encoding and decoding three-dimensional object data are provided to compress depth image information through effective predictive coding. CONSTITUTION: A three-dimensional object data encoding system includes a tree structure generator(1100), a merging order selector(1110), a node encoder(1120), and a bit stream generator(1130). The tree structure generator receives one of point texture data, voxel data and octree data that represent three-dimensional object data to generate three-dimensional object data having a tree structure in which a label indicating a node type is attached to each node. The merging order selector merging the tree-structure three-dimensional object data with reference to the label. The node encoder encodes the merged node. The bit stream generator generates a bit stream from the encoded node data.
