Line-staggered and tessellated rendering method and device for three-dimensional video

Abstract

The invention discloses a line-staggered and tessellated rendering method for a three-dimensional video, comprising the steps of storing left view and right view of an image of each frame of the three-dimensional video in a first storage space; carrying out smooth scaling on the left view and the right view in the first storage space, and storing the left view and the right view in a second storage space and a third storage space respectively after the views are smoothly scaled; and storing corresponding pixel points of the smoothly-scaled right view and a line-staggered and tessellated module in the third storage space according to the line-staggered and tessellated module stored in the second storage space in advance. The invention also discloses a line-staggered and tessellated rendering device of the three-dimensional video. The method has the advantages that the rendering speed is high and the rendered image is clear. In addition, the device is simple in structure and easy to implement.

Description

technical field [0001] The present invention relates to the field of computer multimedia technology, and especially designs a fast stereoscopic video line interleaving and checkerboard rendering method and device. Background technique [0002] The vigorous development of stereoscopic video has brought about changes in audio-visual playback technology. Three-dimensional stereoscopic video will replace flat video and become the main form of multimedia technology. 3D stereoscopic blockbusters such as "Avatar" are popular all over the world, heralding the arrival of the stereoscopic era. It can be seen that the basic principle of stereoscopic vision perception is that there is a certain parallax in the horizontal direction between the images viewed by the left eye and the right eye, thereby generating a stereoscopic impression in the brain. Stereoscopic video technology is based on this principle. Through certain rendering and display methods, the left and right eyes of the aud...

Problems solved by technology

[0004] The disadvantage of the prior art is that the traditional stereoscopic video line interleaving and checkerboard rendering methods have slow rendering speed, so when playing high-bit-rate high-definition stereoscopic video, the rendering operation speed is slow, which may lead to unsmooth playback

In addition, in the process of playing while rendering, the rendering speed is always slow, causing the playback to stop and wait for rendering. Therefore, the viewing effect is not good, so that the user is always in the process of intermittent waiting, which affects the viewing effect
