CROSS REFERENCE TO PRIOR APPLICATION

This application is a National Stage Patent Application of PCT International Patent Application No. PCT/JP2018/024080 (filed on Jun. 26, 2018) under 35 U.S.C. § 371, which claims priority to Japanese Patent Application No. 2017-134534 (filed on Jul. 10, 2017), which are all hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The present disclosure relates to information processing apparatus and method, and specifically to information processing apparatus and method that make it possible to suppress a reduction in encoding efficiency.

BACKGROUND ART

For example, there has been encoding with use of a voxel such as Octree as an existing method of compressing vertex data of a point cloud or a mesh (see, for example, NPTL 1). The point cloud represents a three-dimensional structure by position information, attribute information, and the like of a point set, and the mesh includes vertexes, edges, and faces and defines a three-dimensional shape using a polygon representation.

In the encoding with use of the voxel, as a precondition, it is necessary to normalize position information of an encoding target; therefore, an operation of setting a solid, called a bounding box, including the encoding target is performed.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

However, in a case of encoding with use of the voxel, there is a possibility that encoding efficiency is reduced if this setting of the bounding box is not appropriate.

The present disclosure has been made in light of such circumstances, and makes it possible to suppress a reduction in encoding efficiency.

Means for Solving the Problems

An information processing apparatus according to one aspect of the present technology is an information processing apparatus including a generator that generates information relating to quantization of a three-dimensional position of an encoding target.

An information processing method according to one aspect of the present technology is an information processing method including generating information relating to quantization of a three-dimensional position of an encoding target.

An information processing apparatus according to another aspect of the present technology is an information processing apparatus including a restoring unit that restores three-dimensional information of an encoding target from a signal string on the basis of information relating to quantization of a three-dimensional position of the encoding target.

An information processing method according to another aspect of the present technology is an information processing method including restoring three-dimensional information of an encoding target from a signal string on the basis of information relating to quantization of a three-dimensional position of the encoding target.
