Abstract
Provided is a real-time aliasing rendering method for a 3D VR video and a virtual three-dimensional scene, including: capturing 3D camera video signals in real time and process the same to generate texture data; creating a virtual three-dimensional scene according to the proportion of a real scene; generating virtual camera rendering parameters according to a physical position of the 3D camera and a shooting angle relationship; aliasing the texture data onto a virtual three-dimensional object in a virtual scene, and adjusting the position of the virtual three-dimensional object according to a physical positional relationship between the virtual three-dimensional scene and the real scene, so as to form a complete virtual reality combined three-dimensional scene; rendering the virtual reality combined three-dimensional scene by using the virtual camera rendering parameters to obtain a simulated rendering picture.
