Remote presenting system, device, and method
View Patent ↗A remote presenting system, includes: a plurality of displays, configured to display a remote image; an audio output apparatus, configured to output remote audio information; a multimedia communication terminal, configured to process and control audio/video information obtained by a local end and audio/video information sent by a remote end; a plurality of video cameras, configured to shoot a local video image and send the shot video image to the multimedia communication terminal to be processed; an audio collection apparatus, configured to collect local audio information, and send the collected audio information to the multimedia communication terminal; and a plurality of user locations, corresponding to the plurality of video cameras respectively, and respectively being in an approximately perpendicular relationship with optic axes of camera lenses of the plurality of video cameras.
1. A remote presenting system, comprising:
a plurality of displays configured to display image information of a multimedia communication remote end;
a multimedia communication terminal, connected to the plurality of displays, and configured to process a video signal of the multimedia communication remote end, display a video image of a remote end through the plurality of displays, process local video data information and send the processed video data information to the multimedia communication remote end;
a plurality of video cameras, connected to the multimedia communication terminal, and configured to shoot a video image of a multimedia communication local end, and send the shot video image to the multimedia communication terminal for processing; and
a plurality of user locations, corresponding to the plurality of video cameras respectively, wherein visual field perpendicular planes of the plurality of user locations are respectively in an approximately perpendicular relationship with optic axes of camera lenses of the plurality of video cameras; and
wherein the displays are placed on a presenting desktop, the video cameras are disposed at a frame above the displays, and a conference table and conference chairs are placed at the other side of the display desktop; by utilizing the frame size of the remote display, the distance from a display to a conference table, the location placement between video cameras, and the range of a shooting visual angle of a video camera, the image missing zone or the image overlapping zone shot by the remote video camera may be just obstructed by the frame of the local display.
2. The system according to claim 1 , wherein parameters of the plurality of video cameras of the system, parameters of the user locations, and dimensions of the remote displays are set, so that content represented by the plurality of remote displays appears continuous.
3. The system according to claim 1 , wherein an included angle of a shooting range of each video camera of the plurality of video cameras is determined by a ratio of the width of a user location corresponding to the video camera to the distance from an optical center of the video camera to the user location, and a range of the included angle is between 26° to 36°.
4. The system according to claim 1 , wherein a range of an included angle between principal optic axes of every two adjacent video cameras of the plurality of video cameras is between 29° to 37°.
5. The system according to claim 1 , wherein the plurality of user locations is placed in multiple rows.
6. The system according to claim 5 , wherein the user locations placed in multiple rows are placed in a step manner.
7. The system according to claim 1 , wherein the plurality of displays is placed on a presenting desktop, and a back of a presenting direction of the presenting desktop is used to mount a user seat, wherein the plurality of displays on the presenting desktop are placed into the presenting desktop in a lifting manner.
8. The system according to claim 1 , further comprising: a video camera, configured to perform target positioning and tracking on a speaking conference participant.
9. The system according to claim 1 , wherein the displays are displays having a diagonal dimension greater than or equal to 60 inches.
10. The system according to claim 1 , wherein a plurality of auxiliary displays is placed on a conference table disposed at the plurality of user locations, and the auxiliary displays are configured to display shared multimedia data information.
11. The system according to claim 10 , wherein the auxiliary displays are hidden into the conference table in a lifting manner.
12. The system according to claim 10 , wherein a centralized control apparatus is disposed on the conference table, and the centralized control apparatus is connected to the multimedia communication terminal, and is configured to implement control on multimedia communication.
13. The system according to claim 12 , wherein the centralized control apparatus is configured to set up or release a call, set a system parameter, adjust lighting of a conference room, and control window curtains of the conference room.
