V-PCC 3D Bounding Box Scale Parameter for AR Point Cloud Integration

The patent applies preliminary action by pre-defining a standard 3D bounding box size (e.g., 1 meter cube) for coding point clouds. This standardized coordinate system is established in advance during encoding, allowing efficient storage and transmission. The scale factor is pre-calculated based on the ratio between the standard bounding box and the actual object bounding box, enabling later scaling operations during AR integration without requiring re-encoding of the original point cloud data.

The patent applies parameter changes by introducing a scale factor parameter that transforms the point cloud from the standardized coordinate system to real-world dimensions. Instead of storing multiple versions of the point cloud or using complex coordinate transformation matrices, the solution changes the scaling parameter directly. The scale factor is signaled in the bitstream alongside existing bounding box parameters, allowing the decoder to apply uniform scaling to achieve proper AR integration while maintaining relatively simple processing requirements.
