Abstract

The invention discloses a video picture switching method, a video picture switching system, a recording and broadcasting server and a video recording and broadcasting system, which are used for switching video pictures in a speaker tracking mode in the recording and broadcasting process of a meeting. The video picture switching method comprises the following steps that trigger conditions of video picture switching in a target tracking mode are preset; a cloud platform camera continuously tracks a target to acquire a video picture of the target, and when the trigger conditions are met, a recorded and broadcast video picture is switched into a meeting place panoramic video picture from the video picture shot by the cloud platform camera; and when the cloud platform camera completes regulation and the trigger conditions are not met, the recorded and broadcast video picture is switched back into the video picture shot by the cloud platform camera. The problem that in the prior art, the video picture is discontinuous due to a mechanical process, an installation position and a tracking technology of a cloud platform, or due to the excessive moving speed of a lens of the camera, a video is unsmooth so that a user generates a dizzy feeling is avoided; and user experience is promoted.

Description

technical field [0001] The invention relates to the technical field of video recording and broadcasting, and more specifically relates to a video screen switching method, system, recording and broadcasting server and video recording and broadcasting system. Background technique [0002] The existing intelligent tracking and shooting products used in multimedia education or intelligent recording and broadcasting classrooms can analyze the behavior of characters in real time, so as to control the movement of the camera to track the shooting target and realize the switching between multiple shots. [0003] Existing devices on the market unilaterally emphasize the accuracy of video analysis, with little improvement in user experience. The recorded video file is not good, lacks the end of the transition, has a lot of shaking shots, and the transition between shots is unnatural. figure 1 It is an existing camera layout scheme for the recording and broadcasting system of a multime...
