the synthesis module synthesizes a demonstration file, the demonstration area portrait and the demonstrator audio to obtain a demonstration video;
and the synchronization module synchronously displays the demonstration video and the portrait of the participation area.
The technical effect shows that the participants need to synchronize videos shot by own camera videos in real time, so that the presenter can watch the head portrait list of the participants in real time, and the students can conveniently monitor the class situations. Meanwhile, the participants can also acquire videos shot by the cameras of the presenter in real time for watching the presentations of the presenter.
It should also be noted that the participants can watch the demonstration file played by the presenter, the portrait of the presenter and listen to the audio of the presenter in real time, and the richness and the demonstration effect of the remote video conference demonstration can be greatly improved through the effect that the demonstration file and the camera video stream appear and interact simultaneously.
In addition, the step of acquiring the image of the presentation area, the audio of the presenter and the image of the participation area in real time comprises the following steps:
acquiring an image of a demonstration area shot by a camera in real time;
acquiring images of the participating areas shot by a camera in real time;
and acquiring the audio of the presenter recorded by the recording equipment in real time.
Correspondingly, the obtaining module further includes:
the first acquisition unit is used for acquiring images of the demonstration area shot by the camera in real time;
the second acquisition unit is used for acquiring images of the participating areas shot by the camera in real time;
and the third acquisition unit acquires the audio of the presenter recorded by the recording equipment in real time.
The technical effect is that to realize smooth remote video conference, a video recording device and a sound recording device are needed, a camera of a presenter aims at a presenter to shoot images of a presentation area in real time, and the images of the presentation area are transmitted to a computer of a participant from a computer of the presenter in real time through a remote network; the camera of the participant aims at the presenter, the image of the participation area is shot in real time, and the image of the participation area is transmitted to the computer of the participant from the computer of the presenter in real time through a remote network; when the presenter gives a speech, the recording device can record the audio frequency of the presenter in real time, and the audio frequency of the presenter is transmitted to the computers of the participants from the computers of the presenter through a remote network.
It should be noted that the present invention creatively transmits the images and audio of the presenter to the participants in real time, and simultaneously transmits the images of the participants to the presenter, so as to realize the function of synchronizing the images of the presenter and the participants with each other, and the participants can simultaneously receive the audio of the presenter, thereby increasing the vivid degree of the presentation video and enabling the remote video conference to be more orderly.
In addition, the step of identifying the portrait of the demonstration area image and the participation area image to obtain the portrait of the demonstration area and the portrait of the participation area comprises the following steps:
identifying whether a portrait exists in the image of the demonstration area;
if the portrait exists, acquiring an area contained in the portrait;
processing the area which does not contain the portrait in the demonstration area in a pixel blank mode;
identifying whether a portrait exists in the images of the participating area;
if the portrait exists, acquiring an area contained in the portrait;

Technical effects show that images of a presenter and participants shot by a camera of the presenter usually contain a portrait and a background, and the participants and the presenter only need to see the portrait and do not need to show the background behind the portrait. Therefore, in the application, whether a portrait exists in an image shot by a camera can be firstly identified, if the portrait exists, a region containing the portrait is extracted through a portrait edge detection technology, and a background region except the portrait in the image is transparently processed according to pixels, so that the portrait watched by a presenter or the portrait watched by a participant is only a human body part, and the background part except the human body part cannot be seen. The mode of only showing the portrait by scratching out the portrait highlights the human body, and is beneficial to the demonstrator and the demonstrator to observe the expression of the other side more clearly.
