Sony patents method to speed up 3D point cloud decoding
Sony has been granted a patent for a method that organizes 3D point cloud data in a specific order to make decoding faster. The system arranges the data so that the computer processes the shape information in the same sequence as the color or texture details, reducing the workload on the processor.
In the filing’s own words
There is provided an information processing apparatus and method which enable an increase in a load of decoding processing of coded data of a point cloud to be suppressed. Positional information of a point cloud expressing an object with a three-dimensional shape as a set of points is encoded in an order which causes a decoding result of coded data of the positional information to be output in a processing order of attribute information of the point cloud, and coded data thereof is generated. In addition, coded data of positional information of a point cloud expressing an object with a three-dimensional shape as a set of points is decoded and a decoding result thereof is to be output in a processing order of attribute information of the point cloud. For example, the present disclosure can be applied to an information processing apparatus, an image processing apparatus, a coding apparatus, a decoding apparatus, an electronic device, an information processing method, a program, or the like.
What exactly they claim (claim 1)
1. A coding apparatus for point cloud data expressing a three-dimensional object, comprising: circuitry configured to: encode first geometry data of the point cloud data to represent an octree structure in a Morton order as an output point order of the geometry data corresponding to a processing order of attribute data of the point cloud data; encode second geometry data of the octree structure on a basis of a direct coding where the second geometry data directly belongs to a corresponding node of the octree structure; and generate control information representing an output point order of the second geometry data in accordance with the Morton order.
