    摘要: A telepresence system includes a camera pair remotely controlled by a control module affixed to an operator. The camera pair provides for three dimensional viewing and the control module, affixed to the operator, affords hands-free operation of the camera pair. In one embodiment, the control module is affixed to the head of the operator and an initial position is established. A triangulating device is provided to track the head movement of the operator relative to the initial position. A processor module receives input from the triangulating device to determine where the operator has moved relative to the initial position and moves the camera pair in response thereto. The movement of the camera pair is predetermined by a software map having a plurality of operation zones. Each zone therein corresponds to unique camera movement parameters such as speed of movement. Speed parameters include constant speed, or increasing or decreasing. Other parameters include pan, tilt, slide, raise or lowering of the cameras. Other user interface devices are provided to improve the three dimensional control capabilities of an operator in a local operating environment. Such other devices include a pair of visual display glasses, a microphone and a remote actuator. The pair of visual display glasses are provided to facilitate three dimensional viewing, hence depth perception. The microphone affords hands-free camera movement by utilizing voice commands. The actuator allows the operator to remotely control various robotic mechanisms in the remote operating environment.

    摘要: A stereoscopic 3D display comprises a light source and condenser optics which direct light through a spatial light modulator and a polarisation modulator. Each of the modulators is pixellated with the pixels of one modulator being optically aligned with respective pixels of the other modulator. Each pixel of the spatial light modulator is controlled so as to provide a light amplitude which is equal to the square root of the sum of the squares of the corresponding pixels of the stereoscopic images. Each pixel of the polarisation modulator is controlled so as to supply output light with a polarisation angle give by the arc-tangent of the quotient of the pixel amplitudes of the stereoscopic images. Polarising glasses with suitably aligned polariser lenses allow an observer to perceive the 3D effect, for instance on a polarisation preserving screen on which the encoded stereoscopic image is projected by projection optics.
