摘要

A method of capturing data for use in a video conference includes capturing data of a first party at a first location using an array of one or more video cameras and/or one or more sensors. The three-dimensional position(s) of one or more features represented in the data captured by the video camera(s) and/or sensor(s) are determined. A virtual camera positioned at a three-dimensional virtual camera position is defined. The three-dimensional position(s) determined for the feature(s) are transformed into a common coordinate system to form a single view of the feature(s) as appearing to have been captured from the virtual camera. The video image and/or sensor data of the feature(s) viewed from the perspective of the virtual camera and/or data representative of the transformed three-dimensional position(s) of the feature(s) are then transmitted or stored.

說明書

Video conferences allow parties who are in different locations, e.g. rooms, buildings, cities and even countries, to communicate with each other by exchanging video image and sound data over a video conferencing call. Some exemplary systems, in accordance with embodiments of the present invention will now be described.

FIG. 1 shows a room 1 in which at least part of a video conferencing system according to an embodiment of the present invention is installed. The system includes multiple video cameras 2 mounted in an array around a video display screen 3. The video cameras 2 are arranged to capture video image data of the users of the video conferencing system who will typically be sitting on the chairs 4 around the table 5 in the room 1 (the users are not shown for the purposes of clarity). The display screen 3 is arranged to display video image data of users at the other end of the video conferencing call.

The system also includes a microphone and loudspeaker unit 6 (or an array of multiple such units) on the table 5 (or other suitable location). The microphone and loudspeaker unit 6 is arranged to capture sound data of the users of the video conferencing system and to output the sound captured from the users at the other end of the video conferencing call.
