Problems solved by technology

The problem with the above-mentioned live broadcast method is that the viewing angle of the audience is relatively single and uncontrollable. The audience can only passively accept the current live broadcast angle, but cannot freely choose the angle they want to see
However, the traditional bullet time is a late-stage special effect, which cannot be applied to live broadcasts, and the clip selection and speed of the bullet time effect are determined by the special effects producer. Users cannot watch the bullet time effect at any moment they like. very restrictive

Abstract

The invention discloses a live video broadcast processing method, equipment and system based on a free viewpoint, a chip and a medium. The method comprises the following steps: collecting a pluralityof synchronous videos at multiple angles; splicing the plurality of synchronous videos into a large graph, and transmitting the large graph to a server; and decoding on a server to obtain a large graph, and selecting an angle for playing. According to the invention, a user can freely switch viewpoints, and the effect of customizing the bullet time is realized through sliding control.

Description
