in particular, when a user at a different location needs to conduct a video conference, it is often necessary to arrange a display screen for displaying other video conference participants at a remote end.
As shown in fig. 3, a local conference table may be provided locally, and a display screen may be provided in front of which a plurality of cameras may be provided, which may capture dynamic image information of local video conference participants.
Similarly, a video participant at another remote location may also set a local conference table and a camera, which are not described in detail.
202, separating the user image from the background image to obtain an independent user image;
specifically, after the camera collects the image information of the video conference participant, the image information is sent to the data processing subsystem, and the image processing program running in the data processing subsystem separates the image affecting the participant from the background image in the image data, as shown in fig. 4.
203, creating at least one virtual conference table;
specifically, the image processing software running in the data processing subsystem may create a plurality of virtual conference tables through a 3D effect graph, for example, as shown in fig. 5, the virtual conference table may be a complete conference table, or a conference table with a large volume formed by splicing a plurality of conference tables with a small volume, and may further include one or more speaking tables. For example, the first row of virtual conference tables in the upper left corner of fig. 5 are speech tables on both sides.
204, overlapping the independent user image and the virtual conference table to obtain an overlapped image;
specifically, the image processing software running in the data processing subsystem may arrange the created virtual conference tables into a required number of rows, and adjust the display size of the virtual conference tables in the order of distance, height, and the like.
Similarly, the image processing software running in the data processing subsystem may also combine the independent images of the video conference participants with the created virtual conference table according to the set sequence, so that the image sizes of the video conference participants also need to be adjusted according to the sequence of distance, height, and the like, and the effect is as shown in fig. 6.
