Intelligent front end system of video conference

Abstract

The invention discloses an intelligent front end system of a video conference, comprising a set of voice and video recording equipment, a video conference camera, a conference system control unit, an audio and video matrix switcher and a video processor. In the intelligent front end system, by collecting voices and video images of a speaker at a conference scene and a full-view video image at the conference scene, priority level managements of the voices and video signals of a whole conference system are controlled, a plurality of audio and video signals in the conference system are synchronously switched, the face of the speaker is detected and a image of the face is cut, the full-view video image at the conference scene is recovered and the face of the speaker is overlapped with the full-view video image at the conference scene. The intelligent front end system of the video conference has the beneficial effects as follows: in one video image, not only the face of the speaker can be accurately seen, but also the full view of a conference place can be seen; and on the condition of not changing the traditional video conference system basically, the intelligent upgrade of the video conference can be realized.

Description

technical field [0001] The invention relates to the field of video conferencing systems, in particular to an intelligent front-end system for video conferencing. Background technique [0002] With the rapid development of video camera technology, network broadband technology, video compression technology and storage technology, video conferencing is widely used in local or remote meetings in various occasions. [0003] Such as figure 1 As shown, the basic working principle of the video conferencing system is: collect audio signals and video signals through the front-end acquisition device 10 of the microphone and camera, use the video conferencing host 20 to compress the collected audio and video signals and store them locally or use the network device 30 After being transmitted to the remote end, local or remote compressed audio and video signals are selected according to the control signal of the main control system 40, decoded by the video conferencing host 20, and sent ...

Problems solved by technology

However, on the one hand, this solution is easily affected by noise or the voice of a non-speaker, which leads to inaccurate judgment of the source of the sound, which leads to the inability to rotate the control camera and capture the face of the speaker; on the other hand, the placement of the camera or The rotation control is more complicated, and the bigger disadvantage is that even if the camera can be adjusted in place, you can only see the speaker clearly, but you cannot see the whole picture of the venue, which is very different from our real conference site
