Fig. 3 is a schematic flowchart of a method for implementing a teleconference, provided by an embodiment of the present application. The method steps may be performed by a server. As shown in fig. 3, the method includes the following steps S310 to S340.
Step S310: and receiving a conference participation request of a specified conference sent by the conference participation client.
For example, the designated meeting may be an xx academic meeting, and the server may store a virtual meeting scene screen of the xx academic meeting in advance. The conferencing clients may include an instructor-side client, a support person-side client, and an audience-side client. All persons (instructor, audience and host) who need to participate in the conference can send a conference joining request to the server through respective client sides, and the conference joining request can carry the identities of the participants (instructor, audience and host) and the names of the participated conferences (xx academic conferences). And the server receives the participation request sent by the participation client. Step S320: and responding to the conference participating request, and acquiring a virtual conference scene picture of the specified conference.
After receiving the conference participating request, the server can obtain a three-dimensional virtual conference scene picture corresponding to the conference name according to the conference name carried by the conference participating request. The three-dimensional virtual conference scene picture refers to a picture in a three-dimensional virtual conference scene, and the three-dimensional virtual conference scene is an imaginary three-dimensional conference scene, so that an environment for participating in a conference is created for a user. As shown in fig. 4, a three-dimensional virtual meeting scene may include a virtual table and chair 401, a virtual character 402, a virtual curtain 403, and the like. Wherein a participant may be represented by a virtual character. The three-dimensional virtual meeting scene picture comprises virtual characters corresponding to the participants. The virtual meeting scene picture is the picture of the virtual meeting scene.
In an alternative embodiment, the conference client may be a game client, may be a local game client (e.g., a PC-side mobile-side game software application), or may be a cloud game client (e.g., a cloud game access software, a browser, etc.), and the virtual conference scene of the designated conference may be a three-dimensional virtual scene in the game.
Step S330: and streaming the three-dimensional virtual conference scene picture to the participating client.
With the joining, quitting and moving of the virtual characters, the scene picture of the virtual conference can change in real time along with time. "Streaming" is a technology for compressing and transmitting video and audio in real time over a network. The participating client does not need to download complete multimedia data and then play the multimedia data, but continuously transmits the multimedia data from the server to the participating client in real time like water flow. Because the three-dimensional virtual conference scene picture can be changed in real time, the server side can transmit the real-time virtual conference scene picture to the participating client side in a streaming mode, so that the participating client side can obtain the latest three-dimensional virtual conference scene picture in time.
In an embodiment, the participant can click a designated button, so that the participant client receives a first operation instruction triggered by the participant and sends a control instruction to the server. And the server receives the control instruction sent by the participating client, and can control the virtual character corresponding to the participating client to execute the action corresponding to the control instruction. The control instruction can be a moving instruction, a jumping instruction and the like, so that the virtual character corresponding to the participant is controlled to move or jump to form a new three-dimensional virtual conference scene picture.
Step S340: and streaming the captured conference demonstration interface to the participating client so as to play the conference demonstration interface in a demonstration area of the three-dimensional virtual conference scene picture.
The conference presentation interface is a presentation interface corresponding to a presentation file played in a three-dimensional virtual conference scene corresponding to the teleconference. For example, the meeting presentation interface may be the interface when a computer plays a video, PPT, or text file. In one embodiment, the real-time demonstration interface of the computer can be obtained by means of screen capture. The computer may be a virtual machine or a physical desktop computer, which may be remotely controlled by the instructor through another computer or a computer directly controlled by the instructor.
The server side can acquire the captured conference demonstration interface and stream the conference demonstration interface to the participating clients, and captures a frame and sends the frame to the participating clients in real time, so that the conference demonstration interface received by the participating clients is consistent with the interface controlled by the instructor. In order to enable the conference to be more real, a virtual curtain (or a scene area for displaying such as a virtual display) is arranged in a scene picture of the three-dimensional virtual conference, and the conference client can play a streaming conference demonstration interface in the virtual curtain area (equivalent to a demonstration area) of the scene picture of the three-dimensional virtual conference through an embedded browser, so that the visual experience of watching PPT and video in the conference is more real.
In one embodiment, the multiple participating clients can perform real-time audio and video communication through the server, the server can establish connection among the multiple participating clients and forward the audio and video signals of one participating client to other participating clients, so that participants can receive voice signals and video signals sent by the participating clients while watching a conference demonstration interface in a three-dimensional virtual conference scene, and the amount of information available for a teleconference is enriched.
In an embodiment, the acquiring, in response to the meeting participation request, a virtual meeting scene picture of the specified meeting includes: and according to the participant identity carried by the participant request, capturing a three-dimensional virtual conference scene picture in the three-dimensional virtual conference scene from a view angle corresponding to the participant identity.
The participant identities may include the instructor, the audience, and the moderator. The participant identity can be input into the participant client by the user and sent to the server by the participant client. In one embodiment, the lecturer is located at a lecture station, the audience is located at an auditorium, and the host is located at a corner of the venue, so that the venue areas visible to the lecturer, the audience, and the host are different, and the viewing angles corresponding to the identities of the participants can be considered as the area visible to the lecturer, the area visible to the audience, and the area visible to the host. In order to present a more real visual effect, a picture consistent with the visual angle of the participant identity can be captured from the three-dimensional virtual conference scene according to the difference of the participant identities, and the picture is taken as a three-dimensional virtual conference scene picture and sent to the participant client corresponding to the participant identity.
In an embodiment, because the identities of the participants are different, the requirements of the lecturer, the audience and the host on the understanding degree of the situation in the conference hall are different, for example, the audience does not need to know the situation of the whole conference hall, and only needs to see the content played by the surroundings, the lecturer and the virtual curtain (as shown in fig. 5), and the lecturer needs to know the situation of the whole conference hall (as shown in fig. 4), so that the conference hall range to be presented corresponding to the different identities, that is, the corresponding viewing angle of the identities of the participants, can be set in advance. And according to the meeting place range corresponding to the participant identity and needing to be presented, capturing the three-dimensional virtual meeting scene picture in the range from the three-dimensional virtual meeting scene, and sending the three-dimensional virtual meeting scene picture to the participant client corresponding to the participant identity.
In an embodiment, a user may operate a control such as a virtual joystick or operate in a designated angle-of-view adjustment area, trigger the client to send an angle-of-view adjustment instruction to the server, and the server receives the angle-of-view adjustment instruction sent by the participating client. The visual angle adjusting instruction may include a specific visual angle, and the server acquires a three-dimensional virtual conference scene picture of the corresponding visual angle from the three-dimensional virtual conference scene according to the visual angle adjusting instruction, and streams the three-dimensional virtual conference scene picture to the participating client again. Therefore, the user can independently adjust the visual angle and observe pictures in different directions in the three-dimensional virtual conference scene.
In an embodiment, as shown in fig. 6, before the step S310, the method provided in the embodiment of the present application further includes a step S301 and a step S302.
Step S301: and receiving user registration information which is sent by the participant client and contains the personal photos of the participants and the selected virtual roles.
Each participant can send user registration information to the server in advance through the respective client. The user registration information may include personal photographs of the participants, selected virtual characters (e.g., fairy, rancher). The user registration information may also include participant contact details, such as phone calls, mailboxes, etc., as desired.
Step S302: and generating a virtual character corresponding to the participant in the three-dimensional virtual conference scene through an intelligent face pinching technology according to the personal photo of the participant and the selected virtual character.
The intelligent face-pinching technique refers to approximating the facial features of a virtual character to the facial features of a participant. In one embodiment, the server may take the face photos of the participants as input through the trained network model, and output the face-pinching parameters. The face pinching parameters include continuous bone parameters (displacement, size, rotation angle, such as eye size, eyebrow height, cheek fat and thinness, etc.) and discrete maps and color sequence numbers (such as eyebrow shape, lip color, beard pattern, etc.). The facial parameters of the virtual character are adjusted based on the pinching parameters to form a virtual character similar to the participant. A virtual character refers to a character within an imaginary scene that is similar to the face of a participant. The three-dimensional virtual meeting scene comprises virtual characters corresponding to the participants, so that a more real scene of the meeting is created.
In an embodiment, the user registration information may further include a user contact address; before the step S310, the method provided in the embodiment of the present application further includes: and sending a meeting notification to a meeting client corresponding to the user contact information according to the user contact information.

The server responds to the remote demonstration instruction and plays the demonstration file. The presentation file may be a PPT, PDF file, video file, word file, etc.
The conference presentation interface refers to a presentation interface corresponding to a presentation file played in a three-dimensional virtual conference scene corresponding to a teleconference. Optionally, the presentation interface may be a virtual display, a virtual curtain, or the like in the game scene.
In an embodiment, the server may receive a remote demonstration instruction sent by the instructor terminal by operating a virtual machine, and the virtual machine plays a demonstration file and captures a conference demonstration interface corresponding to the demonstration file under the control of the remote demonstration instruction.
The virtual machines may be deployed on a single server, i.e., the virtual machines may be independent virtual machines. The independent virtual machine is an emulator of a computer system, and can provide the functions of a physical computer by simulating a complete computer system having the functions of a complete hardware system and running in a completely isolated environment through software, that is, the independent virtual machine is equivalent to a computer.
The independent virtual machine is controlled by the remote of the instructor terminal, and can receive remote demonstration instructions of the instructor terminal, such as instructions of showing PPT, turning pages, opening pdf and the like. After the independent virtual machine receives the remote demonstration instructions, the demonstration file can be played in the independent virtual machine. In the process of displaying the presentation file, the independent virtual machine can also record a screen, that is, the conference presentation interfaces are stored in one frame, for example, 60 times in one minute, so that 60 conference presentation interfaces are obtained every minute.
