    摘要: A convertible 2D/3D autostereoscopic display includes of an electronically controllable display screen for displaying two dimensional images thereon and a permanently mounted first lens sheet for projecting 3D autostereoscopic images in a region of space in front of the display. Another lens sheet is pivotally attached to the display to allow it to be swung into and out of physical optical engagement with the first lens sheet. The lens sheets each have complimentary physical structure and optical properties such that when the lens sheets are engaged, the combined lens sheets have a substantially negligible effect on the two dimensional screen image; while disengagement of the lens sheets resumes the display to the 3D autostereoscopic display mode. Complimentary alignment structure is also provided in corresponding non-lens regions of the lens sheets for aligning the respective lenslets when the sheets are engaged. Conventional latches are also provided to secure the lens sheets when they are engaged. In another embodiment, a lens sheet is selectively engageable with a 2D display to form 3D autostereoscopic images when in a closed position and allow 2D viewing when in an open position.

    摘要: A rolling loop motion picture projector is convertible for projecting images either from a 2-D film strip or from a 3-D film strip. The film is advanced through the same incremental amount irrespective of whether a 2-D film of a 3-D film is being projected. The projector has a single central aperture for projecting 2-D images and respective 3-D images on opposite sides of the central aperture. The images on the 3-D film strip are anamorphically compressed in the direction of film travel by a factor of two and the 3-D apertures are correspondingly sized. Projection lenses associated with the 3-D apertures decompress the images so that images of comparable size appear on the screen irrespective of whether a 2-D film or a 3-D film is being shown.

    摘要: A stereoscopic remote viewing system includes a pair of spaced apart cameras mounted on a platform which is movable along a semicircular support track for azimuth aiming of the cameras. The track is pivotable about a diametric axis for elevation aiming of the cameras. The cameras are connected through selection switches to a head worn video display unit having a pair of cathode ray tubes (CRT's) mounted therein. Lenses and mirrors are positioned to project the images reproduced by the CRT's indirectly into the eyes of a viewer. A digital computer is connected through the selection switches and is employed for the storage and retrieval of texts and graphic information related to the operations viewed with the system.

    摘要: The embodiments of the present disclosure relate to the technical field of virtual reality, and disclose a free viewing method for a three-dimensional video and an electronic device. In some embodiments of the present disclosure, respective rotation matrices of a current viewpoint in three dimensional directions are calculated; a current viewing orientation is calculated according to the rotation matrices in the three dimensional directions and an original viewing orientation; an orientation matrix of a viewer is calculated according to the current viewing orientation; a three-dimensional video is played by using an inverse matrix of the calculated orientation matrix as a position of a three-dimensional video in the coordinate system of the viewer. Adopting the embodiments of the present disclosure enables the display of a three-dimensional video to automatically adapt to a current viewpoint position of a user along with free change of the position of the user.
