Method and terminal for realizing virtual rocker arm

Abstract

The invention provides a method and a terminal for realizing a virtual rocker arm. The method comprises the following steps: calculating spatial position parameter information of a real camera in a real scene; assigning the spatial position parameter information of the real camera in the real scene to a virtual camera; generating a vertical rendering surface, wherein the vertical rendering surface is parallel to a projection plane in a three-dimensional view frustum; mapping a video image of the real scene shot by the real camera onto the vertical rendering surface; corresponding the vertical rendering surface into a virtual three-dimensional scene, wherein there is a three-dimensional virtual object in the three-dimensional scene; if a motion parameter is received, controlling the virtual camera to move according to the motion parameter; and rendering the vertical rendering surface together with the three-dimensional virtual object, wherein the vertical rendering surface is consistently located on the mot bottom layer during the rendering. By adopting the method and the terminal, an effect of the virtual rocker arm of a virtual implantation system is achieved, the operation is simple, the use is convenient, and no goof phenomenon is generated.

Description

technical field [0001] The invention relates to the field of virtual technology, in particular to a method and terminal for realizing a virtual rocker. Background technique [0002] Virtual implant technology is to digitally synthesize the virtual 3D scene produced by the computer and the moving images of the characters captured by the camera in real time. When the camera scene changes, it can keep the characters and the virtual 3D scene changing synchronously, so as to realize the seamless integration of the two. Blend for the perfect composite picture. Virtual implant technology specifically involves tracking and positioning, virtual 3D scene graphics, subtitles, animation, editing, broadcasting, special effects, keying and other technologies. The virtual implant system is a virtual reality implementation method that uses virtual implant technology for real-scene studios or live-scene stages. In the virtual implant system, it is necessary to realize the virtual rocker ef...

Problems solved by technology

[0004] The essence of the virtual studio is to integrate the foreground characters into the virtual three-dimensional scene as a one-dimensional depth, and the essence of the virtual implant system is to integrate the three-dimensional virtual objects into the three-dimensional real studio or stage. This kind of object can no longer be regarded as a one-dimensional depth patch, but has a three-dimensional depth of field relationship, so the virtual rocker implementation method based on the virtual studio system cannot be directly used in the virtual implant system.

At present, the application of the virtual rocker arm has not been seen in the virtual implant system, so the realization of the virtual rocker effect in the virtual implant system is of great significance to the magnificent and atmospheric video program effect based on the real stage or live studio.
