Problems solved by technology

The disadvantage of the magnetic sensor-based approach is that it is invasive: a special marker is attached to the observer
The disadvantage of position detection units based on ultrasonic sensors is that they are not robust enough

Embodiment Construction

[0031] Figure 1A An embodiment of a 3D video conferencing station 100 is schematically shown, including:

[0032] - a video camera 102 for capturing video signals;

[0033] - a depth map calculator 104 for creating a depth map 120 of the user 114 of the 3D video conferencing station 100;

[0034] - a transmitter 106 for transmitting 3D video data based on the video signal and the depth map 120;

[0035] - a receiver 110 for receiving 3D video data that has been acquired by the second 3D video conferencing station 301; and

[0036] - A stereoscopic image generator 108 for generating a stereoscopic image based on the 3D video data received by the receiver 110 . The stereoscopic image generator 108 requires information about the location of the user 114 . This information is retrieved from the depth map 120 generated by the depth map calculator 104; and

[0037] - A stereoscopic effect display device 112 for displaying the stereoscopic image generated by the stereoscopic ima...

Abstract

A 3D video conferencing station includes a video camera for capturing video signals and a depth map calculator for creating a depth map of a user of the 3D video conferencing station. The video signals together with the depth map are transmitted as 3D video data. A stereoscopic display device displays stereo images, which are calculated on the basis of received 3D video data. The depth map which is generated by the depth map calculator is also used for estimating the position of the user in order to control the calculation of the stereo images.

Description

technical field [0001] The present invention relates to a 3D video conferencing station and method. Background technique [0002] In US 5,872,590 an image display device is described which allows viewing of video images in stereoscopic effect. The position of the observer in the stereoscopic effect viewing area is detected by the position detection unit. A right-eye image and a left-eye image are formed by the image forming unit and displayed on the display. By setting the aperture position of the projection optical system, the right eye image is projected to the observer's right eye position, and the left eye image is projected to the observer's left eye position, thereby allowing observation of images with stereoscopic effects. The position detection unit is based either on two magnetic sensors or on two ultrasonic sensors. A disadvantage of the magnetic sensor based approach is that it is invasive: a special marker is attached to the observer. A disadvantage of positi...
