The present disclosure relates to an image processing device and method according to which partial decoding of 3-D data is facilitated. Management information is generated for blocks which are partial regions of a prescribed three-dimensional space region including 3-D data representing three-dimensional structures. On the basis of the management information for the blocks which are partial regions of the prescribed three-dimensional space region including the 3-D data representing the three-dimensional structures, a block satisfying a condition designated by a user is selected, and coded data of the 3-D data within the selected block is decoded. The present disclosure may be applied to an image processing device, an electronic device, an image processing method, a program, or the like.
Description
technical field [0001] The present disclosure relates to an image processing device and method, and in particular, to an image processing device and method capable of more easily performing partial decoding of 3D data. Background technique [0002] Conventionally, for example, there is encoding using an Octree, for example, as a method of encoding 3D data representing a three-dimensional structure such as a point cloud (see Non-Patent Document 1, for example). [0003] The octree is obtained by converting voxels obtained by quantizing position information into a tree structure, and has dependencies between nodes. Therefore, even in the case of decoding a part of the octree, after searching the entire octree and reproducing the configuration of the entire octree, it is necessary to cut out a desired area. Therefore, the amount of processing and usage of resources such as memory are unnecessarily increased. [0004] Incidentally, in the case of encoding a two-dimensional ima...
