Abstract: The present disclosure relates to an imaging processing apparatus and method by which degradation of the quality due to two-dimensional projection of 3D data can be suppressed.
All pieces of data for each position included in 3D data representative of a three-dimensional structure are projected to a two-dimensional plane of plural layers. Further, all pieces of data for each position of 3D data projected to a two-dimensional plane having the number of layers indicated by layer number information are projected to a three-dimensional space. The present disclosure can be applied, for example, to an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, and a program.

Abstract: The present disclosure relates to an image processing apparatus and a method that allow for easier and more appropriate rendering. Coded data is generated by encoding a two-dimensional plane image in which position information and attribute information for a point cloud that represents an object having a three-dimensional shape as a group of points are projected onto a two-dimensional plane, and a bitstream that includes the generated coded data and metadata to be used to render the point cloud is generated. The present disclosure can be applied to, for example, an image processing apparatus, an electronic device, an image processing method, a program, or the like.
