Embodiment Construction

[0027] see figure 1 , figure 1 Shows a flow chart of a video capture method in an embodiment, specifically including steps S11-S14:

[0028] Step S11: Obtain the target to be collected;

[0029] In one embodiment, it is necessary to identify the acquisition target in the game, and the acquisition target can be identified through image. The acquisition target includes global target, focus target, hot spot target, and multi-focus mixed target. In a specific game, the acquisition target includes focus Players, Focus Field, Focus Audience Area, Multi-Focus Players, Global, etc.

[0030] Step S12: Obtain the viewing angle information of the collection target when the preset condition is met, and save the viewing angle information of the collection target;

[0031] In this embodiment, the preset condition includes waiting for a predetermined time interval, or every certain number of video frames. After the video collection terminal monitors the start of the game, it will start t...

Abstract

The invention discloses a video acquisition method, a video acquisition terminal and a video live broadcast system. The video acquisition method comprises the following steps: S1, acquiring a to-be-acquired target; S2, when a preset condition is met, obtaining view angle information of the collection target, and storing the view angle information of the collection target; S3, packaging view angle parameters of the collection target into video data; and S4, sending the video data. The invention also discloses a video acquisition terminal, by utilizing the method and the terminal, multi-view information is added in video acquisition and coding stages, and the watching requirement of multi-view playing at a playing end is realized by matching with a multi-view player, so that the watching experience of a user is obviously improved, and the deployment cost of an acquisition end is also reduced.Therefore, the method has obvious technical advantages and beneficial effects.

Description

technical field [0001] The invention relates to video playback technology, in particular to a video collection method, a video collection terminal and a video live broadcast system. Background technique [0002] At present, various competitive events at home and abroad, especially those with a large amount of information such as sports competitions, are usually presented to the audience through multi-camera and artificially switching camera perspectives. Although photographers can usually successfully capture and switch to the exciting moments of the game, this passive viewing of the audience makes the audience lose their autonomy and has a certain impact on the viewing experience. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the purpose of the present invention is to provide a solution for video collection. [0004] In order to solve the above problems, the present invention proposes a video acquisition method, compr...
