Problems solved by technology

In order to make the images of the participants clear and have high contrast, the current Telepresence system selects the background color based on the premise that the image of the participants is darker and can form a greater contrast with the background. Therefore, usually All adopt lighter gray colors, such as yellow-gray, brown-gray, etc. Otherwise, if the color of the participants' clothing is close to the background color, the video effect will be poor
[0004] During the research and practice of the existing technology, the inventor found the following problems in the existing technology: the background color of the conference room of the Telepresence system is fixed, determined by the decoration, and it is difficult to change
That is to say, the background color of the current video conference venue cannot be changed, so the changed background color cannot be used for related processing

Embodiment Construction

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0060] An embodiment of the present invention provides a method for changing the background of a video conference site, which can realize the change of the background color of the video conference site.

[0061] The background color of the video conference in the prior art cannot be changed, so the background of the conference room of the Telepresence system in the prior art cannot be synthesized in a virtual scene. This is because the current virtual scene synthes...

Abstract

The embodiment of the invention discloses a background replacement method, a virtual scene synthesis method and related systems and devices. The method for changing the background in a video conference site, comprising: obtaining a background color determined according to predetermined rules; sending a switching command carrying the determined background color, controlling the background device to switch according to the determined background color, and converting the The switched background color is used as the background color of the video conference site. A method for synthesizing a virtual scene in a video conference, comprising: acquiring a switched background color, wherein the switched background color is determined by a background control device after acquiring a background color determined according to a predetermined rule, and then sending a switched background color carrying the determined background color The command controls the background device to be switched according to the determined background color; and the virtual scene synthesis is performed according to the obtained background color. The technical solution of the embodiment of the present invention can realize the change of the background color of the video conference.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a background replacement method, a virtual scene synthesis method, and related systems and devices. Background technique [0002] Telepresence (Telepresence) system is a video conferencing system that creates a virtual meeting environment. The created virtual meeting environment fully reflects the human factors of the participants and replicates the real experience of the participants as much as possible. The advantages of the Telepresence system over traditional video conferencing systems include: life-size images, smooth motion, precise body behavior, high-definition studio-level video, and approximate eye contact for large user groups, etc., so the Telepresence system can Greatly improve user acceptance, thereby increasing usage and improving user satisfaction. [0003] The environmental engineering decoration of the meeting room of the Telepresence system is a...
