Embodiment Construction

[0034] The core idea of ​​the present invention is: the present invention introduces video as a texture into a three-dimensional platform of an open graphics library (OpenGL, Open Graphics Library), that is, converts video images into textures, and maps the textures to preset three-dimensional graphics, Realize 3D video special effects, realize 3D video special effects by combining video data and 3D graphics, greatly enrich the current video special effects, and generate better 3D video special effects, so that users can experience richer 3D video special effects, and at the same time It can also improve the operating efficiency of the system.

[0035] Referring to Fig. 1, the inventive method comprises steps:

[0036] S101. Convert video images into textures;

[0037] Preferably, adjust the length and width of each frame of image in the video image, and then convert the adjusted each frame of image into texture;

[0038] Preferably, the length and width of each frame of the...

Abstract

This invention discloses a method for realizing 3-D video result including: converting a video image to grains and mapping them onto a preset 3-D pattern to realize the 3-D video result. This invention also discloses a device for realizing it.

Description

technical field [0001] The invention relates to the technical field of video special effects, in particular to a method and device for realizing three-dimensional video special effects. Background technique [0002] In the existing video special effects technology based on the personal computer camera, either the video special effects are directly completed in the image space, or the motion information obtained in the video image data is used to drive the virtual 3D model, but these two kinds of video special effects technologies have potential Video image data and 3D graphics are fused. [0003] At present, the special effects combined with video are generally realized on the two-dimensional image plane. By positioning and tracking the faces in the video, the special effects are directly completed on the two-dimensional image space. These special effects are essentially realized through the filtering of two-dimensional images. , such as special effects such as mosaic, face...
