Embodiment 1

[0053] Such as figure 1 As shown, the method for switching video objects in video communication provided by the embodiment of the present invention includes the following steps:

[0054] 11. Obtain the video image signal and sound information of the venue.

[0055] Video image signals and sound information in the venue can be collected through the camera equipment and the microphone array in the venue.

[0056] 12. According to the video image signal and sound information of the venue, determine the video image signal including the video object that needs to be switched.

[0057] Combined with the acquired video image signal and sound information of the venue, it can be determined which participant in the venue is the current speaker through image recognition technology and microphone array technology, and it can be regarded as the video object.

[0058] 13. Send the switched video image signal to other conference sites.

[0059]The above-mentioned sending of the video imag...

Embodiment 2

[0062] It is assumed that there are four participants P1, P2, P3, and P4 in the first conference site, and the video display device in the second conference site can only display two participants in the first conference site.

[0063] Such as figure 2 As shown, the method for switching video objects in video communication provided by the embodiment of the present invention specifically includes the following steps:

[0064] 21. Acquiring video image signals and sound information of the first conference site.

[0065] 22. Determine the orientation information of each participant in the first conference site relative to the camera device according to the video image signal of the conference site.

[0066] First, through image recognition technology, the images of all participants are identified from the video images acquired by the camera;

[0067] Then, according to the imaging principle of the camera, calculate the orientation of all participants relative to the camera, the...

Embodiment 3

[0100] In order to better implement the above method for switching video objects in video communication, an embodiment of the present invention provides a conference terminal for video conferences; the conference terminal will be described in detail below with reference to the accompanying drawings.

[0101] Such as Figure 11 As shown, the conference terminal provided by the embodiment of the present invention includes a terminal device 111 and a video presentation device 112, an audio output device 113, a camera device 114, and a microphone array 115 respectively connected to the terminal device 111, wherein the terminal device 111 further includes: an acquiring unit 1111, a determining unit 1112, and a sending unit 1113; wherein,

[0102] The acquisition unit 1111 acquires the video image signal and sound information of the venue in the venue through the camera device 114 and the microphone array 115 in the venue, and then the determination unit 1112 determines the video ob...

Abstract

The embodiment of the invention discloses a method, a device and a system for video object switching in video communication, which relates to the technical field of video conferences and is used for realizing the automatic switching of video images during the video conferences. The method for the video object switching in the video communication comprises the following steps: acquiring a video image signal and sound information of a meeting place; determining a video image signal which needs to be switched and contains a video object according to the video image signal and the sound information; and sending the switched video image signal to other meeting places. The method, the device and the system realize the automatic switching of video image signals during the video conferences, thereby avoiding the switching error caused by human factors and improving meeting efficiency.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a method, device and system for switching video objects during a video conference. Background technique [0002] Video conferencing systems enable people in different locations to communicate and collaborate remotely face-to-face. Participants in one conference site can see the participants in other conference sites through the display screen, and hear the voice of the current speaker in other conference sites through the audio equipment, so that the participants feel as if they are in the same physical environment as the participants in other conference sites It's the same as attending a meeting in the venue. Nowadays, in order to improve the efficiency and effect of communication between participants in different venues, many video conferencing systems usually display the participants in real-life size, so it is difficult for the display screen in one venue to displ...
