Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with accompanying drawings and examples.

[0028] see Figure 1 As shown, the method of watching 3D panoramic video on the network video live broadcast platform in the embodiment of the present invention comprises the following steps:

[0029] The shooting step is to use the left camera and right camera dedicated to virtual reality to perform video panoramic shooting of the real scene respectively. The left camera collects the content of the left eye, and the right camera collects the content of the right eye. Because the collected left and right eye contents are all video content, Therefore, the left and right eye contents all contain a plurality of video frames (video frame images), and then the left and right eye contents are time-synchronized, even if the left and right eye contents in the left and right eye contents The video frames are time-synchronized and aligned, and the video frame...

Abstract

The invention discloses a method and system for watching a 3D panoramic video based on a network video live broadcast platform. The method comprises an establishment step of establishing two 3D models in a panoramic player of a terminal device, splitting video data into left and right part content corresponding to left and right eyes, adding the left and right part content to the 3D models, thereby forming panoramic video textures, establishing left and right three-dimensional coordinate spaces in the player of the terminal device, and establishing a 3D visual angle sphere on which the panoramic video textures are mapped, in each coordinate space; an addition step of adding two 3D cameras to each three-dimensional coordinate space and placing the lenses of the 3D cameras at the sphere centers of the3D visual angle spheres; and a rendering step of dividing a display window of the terminal device into left and right parts and rendering the two 3D visual angle spheres on which the panoramic video textures are mapped to the left and right parts of the display window.

Description

technical field [0001] The invention relates to the field of 3D panoramic video display, in particular to a method and system for watching 3D panoramic video based on a network video live broadcast platform. Background technique [0002] When the existing network video live broadcast platform performs live video broadcast, it generally only uses a camera to shoot video data, encodes the video and transmits it to the terminal device used by the user through the network. After the terminal device decodes, it is directly rendered to the display window of the device player . However, in this case, the user can only see a single 2D video without a sense of three-dimensionality, and cannot freely choose a viewing angle. The user experience is poor when watching a live broadcast. Therefore the present invention proposes a method and system for viewing 3D panoramic video based on a network video live broadcast platform with 3D panoramic video effects, wherein the 3D panoramic video...
