Problems solved by technology

In the field of VR live broadcasting, immersive experience is gradually coming into people's field of vision. However, the traditional immersive experience needs to buy and wear professional VR glasses, which are not only very expensive, but also not conducive to people's carrying and live broadcast promotion. Therefore, watching live broadcasts anytime, anywhere become people's higher pursuit
In addition, the previous live broadcast mode does not support the change of the viewing angle of the user, and there are problems such as a very limited field of view and unsmooth switching. Therefore, eliminating blind spots in the field of view and improving the visual experience of users has become an urgent problem to be solved in the field of live broadcasting

Embodiment Construction

[0020] In order to describe in more detail the adaptive control playback method of a VR live broadcast system proposed by the present invention, in conjunction with the accompanying drawings and specific implementation methods, the examples are as follows:

[0021] figure 1 Shown the gravity sensing rendering method based on the VR live broadcast system of the present invention, the method mainly includes the following steps:

[0022] Step S101, the present invention uses threejs engine to construct a virtual scene;

[0023] Step S102, establishing a three-dimensional spherical object with a radius r of 500 and horizontal and vertical split planes of 60 and 40 respectively in the virtual scene, and constructing a grid model through the three-dimensional spherical object and video texture material;

[0024] Among them, the threejs engine creates a video texture object based on the ts live stream, uses the video texture as a material, and pastes a small segment of the ts video ...

Abstract

The invention provides a self-adaptive control playing method based on a VR live broadcast system, and relates to the field of VR live broadcast, and the method comprises the steps: collecting live broadcast streams in real time through employing a panoramic camera, combining and splicing the live broadcast streams into a 360-degree panoramic image, and carrying out the compression coding; pushing the encoded panoramic live broadcast stream to a streaming media server in real time for slice storage; enabling a client browser to obtain the VR live broadcast stream from the streaming media server, decoding the VR live broadcast stream, using an open source three-dimensional drawing engine for conducting 360-degree panoramic drawing on the decoded VR live broadcast stream in combination with gravity induction, and changing the position and direction of the virtual camera accordingly according to the change of the position and direction of the user terminal so as to generate and display live broadcast pictures of different view angles; by means of a feedback memory model, achieving the self-adaptive playing effect on different users. According to the invention, the degree of freedom of watching the live video by the user and the fluency of direction switching are greatly improved, the visual field range is expanded, and the user can enjoy immersive experience without wearing VR glasses.

Description

technical field [0001] The invention belongs to the field of VR live broadcast, in particular to an adaptive control playback method based on a VR live broadcast system. Background technique [0002] With the advent of the 5G era, while bringing huge business opportunities to the online live broadcast industry, people's requirements for the experience and comfort of watching live broadcasts are also getting higher and higher. In the field of VR live broadcasting, immersive experience is gradually coming into people's field of vision. However, the traditional immersive experience needs to buy and wear professional VR glasses, which are not only very expensive, but also not conducive to people's carrying and live broadcast promotion. Therefore, watching live broadcasts anytime, anywhere It has become a higher pursuit of people. In addition, the previous live broadcast mode does not support the change of the viewing angle of the user, and there are problems such as a very limi...
