Description

Real-time transcoding method and system for stereoscopic video based on internet server

Technical field

The invention belongs to the technical field of video conversion, and relates to a stereoscopic video conversion method, in particular to a real-time transcoding method based on an Internet server stereoscopic video; and the invention also relates to a stereoscopic video real-time transcoding system based on an Internet service end. Background technique

With the development of video networks, video programs are experiencing massive growth. More and more netizens are watching videos online, but most of the videos in the network are ordinary two-dimensional video. For network users who like to watch stereoscopic video, it is difficult to find enough stereo video sources to watch. How to convert ordinary video into a body video in real time and display it to the user for viewing, becoming an urgent problem for Internet video.

Currently, the common stereo video formats are: left and right format, top and bottom format, red and blue format, shutter format, etc., wherein the left and right format stereoscopic video is regarded as a general stereo format, because the left and right format stereo video can be converted into other formats. Stereo video. Therefore, if you want to convert ordinary flat video into stereo video, you only need to convert ordinary flat video into left and right stereo video. Other stereo video formats can also be converted according to the same principle. In the 1997 Visual Studies (Vision Research, 1997, pp. 1683-1698), Ning Qian and Richard A. Andersen published "A Physiological Model of a Stereoscopic Combination of Motions and a General Interpretation of the Pulquish Phenomenon" (A Physiological Model for Motion-Stereo Integration and a Unified Explanation of Pulfrich-l ike Phenomena). In this article, they expose a way to convert flat video to left and right stereo video. This patent uses this method to convert planar video and stereo video.

In addition to the above-mentioned techniques for planar video conversion to form a body video, this patent also includes the entire system framework for converting video to form a video on the Internet and converting the stereoscopic video into other formats, including how to transmit video over the Internet. How to convert video on the server side, and how to display modules such as stereo video on the client. Summary of the invention
