Problems solved by technology

[0017] This correlation-based optical flow method has its own shortcomings. First, it calculates the motion vector point by point. When dealing with high-resolution images, the amount of calculation will be quite huge; second, it uses a full search method to find the best The

Embodiment

[0086] (1) Download the Akko&Kayo_p00026 standard test code stream encoded by H.264 from the Internet. This video file is the 2D video file to be converted. Figure 4 It is a screenshot of Akko&Kayo_p00026 video.

[0087] (2) Decode the video file, extract the motion vector of each 4×4 pixel block from the H.264 video decoder, convert it into motion amplitude, and generate a description map. Figure 5 that is Figure 4 The description map corresponding to the video screenshot. (3) The description map is linearly enlarged by 16 times to obtain the initial depth map. Figure 6 that is Figure 4The initial depth map corresponding to the video screenshot.

[0088] (3) Iteratively perform edge correction filtering to obtain a dense depth map with clear and accurate object edges, and complete the expression of 3D video. Figure 7 that is Figure 4 The dense depth map after 1 iteration filtering corresponding to the video screenshot, Figure 8 that is Figure 4 The dense dept...

Abstract

The invention discloses a method for converting 2D video into 3D video in a three-dimensional television system, which comprises the following steps: (1) obtaining a 2D video file to be converted, which is compressed by a video coding standard; (2) decoding to obtain original video, extracting the motion vector information of each 4*4 pixel block from a video decoder and converting the motion vector information into the motion amplitude; (3) describing an initial depth figure of each frame image by the motion amplitude; (4) iterating an edge correction filter wave to obtain a clear, accurate and dense depth figure of an object edge and finishing the expression of the 3D video. The invention obtains the initial depth figure by a middle result of the video decoder and well saves the processing time of signals and the cost of a final product; and an edge correction wave filter is designed so that the problem of obtaining the clear, accurate and dense depth figure of the object edge in an algorithm for obtaining depth based on an image is solved.

Description

technical field [0001] The invention relates to a method for converting 2D video to 3D video in a three-dimensional television system. Background technique [0002] In recent years, the view that "3D TV will become a new technological leap after high-definition digital TV" has become the consensus of academic circles and industrial circles. The 3D TV system can bring people an immersive 3D effect, allowing people to enjoy a visual feast. [0003] When trying to formulate standards for 3D TV content, encoding and transmission in many ways, a topic is naturally on everyone's table. That is how to deal with the 2D video content accumulated over the years? Will future 3D TVs be compatible with traditional 2D content playback, or will the original 2D content be converted into 3D in real time through some technical means, and then played three-dimensionally? Undoubtedly, once the latter technology matures, it will bring unimaginable economic value and unprecedented financial su...
