Title:
VOLUME RENDERING METHOD AND SYSTEM FOR EMBEDDING 2D/THREE-DIMENSIONAL (3D) VIDEO DURING NERF 3D SCENARIO RECONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2024/031251
Kind Code:
A1
Abstract:
The present invention provides a volume rendering method and system for embedding a 2D/three-dimensional (3D) video during NeRF 3D scenario reconstruction. The method comprises: acquiring a viewing angle parameter and a 2D/3D video embedding position, and inputting same into a trained NeRF offline model to obtain an NeRF 3D space scenario; performing image frame voxelization processing on a 2D/3D video stream to be embedded and then embedding same into the NeRF 3D space scenario to obtain a video-embedded 3D space scenario; and performing joint volume rendering on the video-embedded 3D space scenario to obtain a 3D video in which the 2D/3D video stream is embedded under the viewing angle parameter. According to the present invention, existing 2D/3D video resources are fully utilized, and the richness of a volumetric video material library is improved. The production period of existing volumetric videos is shortened, and production costs are reduced.
