Embodiment 1

[0086] The first embodiment of the present invention relates to a method for generating a stereo video pair. From the input display auxiliary information, the three-dimensional video sequence is processed to obtain a three-dimensional video pair P.

[0087] The display auxiliary information described in the present invention includes a virtual view point synthesis mark A and a virtual view point position parameter F, or includes a virtual view point synthesis mark A, a minimum viewpoint number viewpoint selection mark E, and a virtual view point position parameter F:

[0088] The processing of the three-dimensional video sequence includes:

[0089] 1) When the virtual viewpoint synthesis mark A indicates the situation (a1), the smallest viewpoint number video sequence and the second smallest viewpoint number video sequence in the three-dimensional video sequence are selected to form the stereoscopic video pair P; where the smallest viewpoint The serial number video sequence and the ...

Embodiment 2

[0094] The second embodiment of the present invention relates to a stereoscopic video pair generation method. From the input display auxiliary information, the three-dimensional video sequence is processed to obtain a stereo video pair P1. The difference from Embodiment 1 is that the display auxiliary information in the present invention also includes the minimum viewpoint number. The viewpoint is the left view. Mark B.

[0095] The processing of the three-dimensional video sequence includes the processing in Embodiment 1, and further includes:

[0096] 1) When the stereoscopic video pair P obtained in Example 1 is composed of the smallest viewpoint serial number video sequence and the second smallest viewpoint serial number video sequence (that is, the virtual viewpoint synthesis identifier A indicates the situation (a1)), if B Indicate situation (b1), regard the smallest viewpoint number video sequence and the second smallest viewpoint sequence video sequence as the left-view vi...

Embodiment 3

[0101] The second embodiment of the present invention relates to a stereoscopic video pair generation method. From the input display auxiliary information, the three-dimensional video sequence is processed to obtain a three-dimensional video pair P2. The difference from Embodiment 1 is that the display auxiliary information described in the present invention also includes the number C of shifted pixels.

[0102] The processing of the three-dimensional video sequence includes the processing in Embodiment 1, and further includes:

[0103] 1) When C * When it is a positive number or zero, the images in the left-view video sequence (referred to as the left-viewpoint image) in the stereoscopic video pair P obtained in Example 1 are oriented relative to the image at the same time in the right-viewpoint video sequence (referred to as the right-viewpoint image). Pan left (or right) C * Pixels to get the stereo video pair P2;

[0104] 2) C * When it is a negative number, translate the image...

Abstract

The invention provides a stereoscopic video pair generating method applied to the multimedia communication field. A three-dimensional frequency sequence is processed through input display auxiliary information, so that a stereoscopic video pair P is obtained. The display auxiliary information comprises a virtual view point combined mark A and a virtual view point position parameter F or comprises the virtual view point combined mark A, a smallest view point serial number view point selecting mark F and the virtual view point position parameter F. The virtual view point combined mark A processes the three-dimensional frequency sequence on one of the following conditions: a smallest view point serial number video sequence and a second-rate view point serial number video sequence constitute the stereoscopic video pair P; a smallest view point serial number video sequence or a second-rate view point serial number video sequence in a three-dimensional video sequence and a combined virtual view point video sequence constitute the stereoscopic video pair P; three conditions exist for processing the three-dimensional video frequency. The invention further discloses a generating device. The stereoscopic video pair generating method and device can improve visual perception of final three-dimensional display.

Description

Technical field [0001] The invention relates to the field of multimedia communication, in particular to a method and device for generating stereo video pairs. Background technique [0002] Three-dimensional video (3D video) sequences include multi-channel (usually 2 channels) video sequences (corresponding to texture information) and corresponding depth sequences (corresponding to depth information), and are usually called MVD (multi-view video) plus depth) format. The 3D video sequence also contains information such as camera parameters for each viewpoint. Three-dimensional video uses view synthesis technology to generate virtual viewpoint video sequences. Traditional stereoscopic video consists of only two video sequences with fixed viewpoints (that is, left viewpoint and right viewpoint), which is also called a stereos pair. The stereoscopic video pair obtained by the binocular camera may have the problem of excessive parallax between the two-view images. Watching such a s...
