Embodiment 1

[0039] An embodiment of the present invention provides an audio and video teaching recording and broadcasting system, such as figure 1 As shown, it includes: a first camera 1 , a second camera 2 , a third camera 3 , a switching module 4 and a control module 16 .

[0040] in,

[0041]The first camera device 1 is set in the classroom, and is used for taking panoramic shots of the person to be detected when the first person to be detected is located in the first area. The first person to be tested here can be a teacher or other people. The first camera device 1 here can also be a camera or a pan-tilt camera, which is set in the classroom and can be installed above the wall of the fixed recording and broadcasting blackboard 5 , which is connected to the switching module 4 . The first area in the above can be the podium area in the classroom, and the second area in the above can be the student area in the classroom where students attend classes, for example: for remote online lis...

Embodiment 2

[0069] An embodiment of the present invention provides an audio and video teaching control method, which is used in the audio and video teaching recording and broadcasting system in Embodiment 1, such as figure 2 shown, including the following steps:

[0070] Step S1: When the first person to be detected is located in the first area, control the switching module to switch to the first camera device to take a panoramic shot of the first person to be detected.

[0071] Step S2: When the first person to be detected is giving lectures, when the first person to be detected is gesturing for body and / or facial expressions, control the switching module to switch to the second camera device to take close-up shots of the person to be detected.

[0072]Step S3: When the first person to be detected is located in the second area, the control switching module is switched to the third camera device to take a panoramic shot of the first person to be detected, or, when the second person to be...

Abstract

The invention discloses an audio and video teaching recording and broadcasting system and a control method thereof. The system comprises first camera equipment which is used for carrying out the panoramic shooting of a to-be-detected person; the second camera shooting equipment is used for carrying out close-up shooting on the first to-be-detected person; the third camera shooting equipment is used for carrying out panoramic shooting on the first to-be-detected person or carrying out panoramic shooting on the second to-be-detected person and the surrounding environment of the second to-be-detected person when the second to-be-detected person stands up, and then switching from panoramic shooting of the second area to close-up shooting on the second to-be-detected person; and the control module is connected with the switching module and is used for controlling the switching module to mutually switch the first camera equipment, the second camera equipment and the third camera equipment. The interactive details between the first to-be-detected person and the second to-be-detected person can be fully displayed, so that the audio and video recording, playing and publishing effects of remote online education or field teaching are enhanced, and the effect of full-automatic tracking audio and video teaching recording is achieved.

Description

technical field [0001] The invention relates to the technical field of audio and video recording and broadcasting, in particular to an audio and video teaching recording and broadcasting system and a control method thereof.
