Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. This embodiment is only a first embodiment of the present invention but not all embodiments.

[0026] Perform 2D to 3D processing on a 2D video sequence, store the processing results and distribute them through the Internet, and decode and display the 3D video by the client. A simple depth template and a smoothness template are used to describe the depth and depth change smoothness of each image of the 2D video, and the depth template and the smoothness template use the same triangular mesh division. The triangle mesh of the depth template and smoothness template used is described as: using one or two of the two diagonal lines in each image of a rectangular 2D video, divide the rectangular picture into 2 or 4 triangles Area, assign a depth value and smoothness value to the three vertices of each triangular area; the depth value and smoothness value of ...

Abstract

The invention discloses a transmitting and rebuilding method of converting a two dimensional (2D) video to a three dimensional (3D) video based on a depth template. The method comprises the steps that a triangle gridding is adopted to describe the depth template and a smoothness template, the smoothness template indicates depth change intensity of each pixel, the triangle gridding description is encoded by an entropy coding and is stored in a picture head of a video sequence, a decoding end regards a 2D picture as a viewpoint, uses the depth template, the smoothness template and the decoded 2D picture to form a depth picture, and a picture of another viewpoint is generated according to the depth picture and the decoded 2D picture. The method of converting the 2D video to the 3D video based on the depth template can effectively help the decoding end to improve quality of converting the 2D video to the 3D video and be low in transmitting cost.

Description

technical field [0001] The invention relates to the technical field of converting 2D video to 3D video, in particular to a transmission and reconstruction method for converting 2D video to 3D video assisted by a depth template. technical background [0002] At present, 3D video technology is rapidly entering the market, and more and more monitors, TV sets, projectors, etc. of major manufacturers support the playback of 3D video. However, the current 3D video resources are not rich enough, and 3D video shooting and production are difficult and costly. On the other hand, it is also a great pity that a large number of original 2D videos cannot be viewed through a 3D display terminal because they do not have depth information. Therefore, the technology of converting 2D video into 3D video has become a hot topic. [0003] The technology of converting 2D video to 3D video is to generate a depth map of each frame according to the 2D video, and generate a 2D frame from another vie...
