Abstract

This invention discloses a single machine space image projection apparatus, which comprises plane image projection components, converter components for projection light path, conversion input module for different formats and projection image- forming screen. It is characterized by the following: to input the space image with left and right eyelets of different arrangements formats into signal input interface of the space projection apparatus and to horizontally or longitudinally spread compression images with different arrangement formats through the column lens in front of the projection lens; to locate the projection image way-operated components and polaroid adjust components to let the images of left and right eyelets to overlap and project images on the screen. The spectator can experience the cubic effect as were in the real space through wearing a pair of polaroid glasses which automatically separate the left and right images and integrates the vision system contraposition and mathematical logic calculation and sensory information.

Description

The unit stereoscopic image projecting device

The present invention relates to the unit stereoscopic image projecting device.Relate in particular to the unit stereoscopic image projecting device of the stereo-picture that adapts to upper and lower series arrangement form stereo-picture and left and right series arrangement form.

At present both at home and abroad popular stereoscopic video images has the doubly stereo-picture program source of field form and interlaced format, existing stereoprojection all is to adopt the two-shipper projection pattern, projector's projection left-eye image signal, another projector of projection eye image signal, modulate a left side respectively by the orthogonal polaroid of light transmission shaft direction, the projecting light path of right projector, make a left side, the overlapping projection imaging of right projected image is to the metal screen, this stereoprojection mode must be used two projectors, the cost height, three-dimensional programme signal must generate independently left-eye image signal and eye image signal by the synchrodyne separation, sends into a left side respectively, right projector.At present, doubly the stereo video signals of the three-dimensional program source of a form and interlaced format can be play on the teletron spatical television set of 100 hertz of parts at present, as existing small serial production on the brand name computers such as Hisense, Xia Hua, Skyworth, spectators put on liquid crystal glasses can see three-dimensional program.But the broadcast form of this solid exists a lot of shortcomings, the first, and it is very big that the kinescope TV screen can not be done, and picture is less; The second, the liquid crystal glasses that spectators wore has certain weight, wears very uncomfortable for a long time; The 3rd, what the left and right liquid crystal lens of liquid crystal glasses adopted is and the logical switch of the synchronous Electronic Control light of the corresponding timesharing of stereotelevision field scan display synchronization, long-time use easily causes eyes fatigue, particularly in the environment of power frequency fluorescent lamp lighting, the switch of liquid crystal is asynchronous with the power frequency component that drives daylight lamp work, produces tangible scintillation and damages spectators' eyes.

The purpose of this invention is to provide a kind of unit stereoscopic image projecting device, it adopts the unit projection pattern, be applicable to, the right and left eyes stereo-picture and the left side of following vertical series arrangement form, the right laterally broadcast of the right and left eyes three-dimensional image signal of series arrangement form, be applied to the digital three-dimensional film, numeral AV/TV stereoprojection, stereo game, the 3D design, the demonstration of virtual reality and the demonstration of three-dimensional computer, spectators separate the right and left eyes stereo-picture automatically with going up the special-purpose left and right sides orthogonal polaroid glasses of light transmission shaft direction, through the image pixel contraposition of the left and right sides of vision system, mathematical logic computing and fusion, spectators projection of sensation stereo-picture is separated with screen, provide more real three-dimensional perfect the enjoyment to spectators.

The objective of the invention is to realize the unit stereoscopic image projection by following projection arrangement.With the parts of common planar DLP digital-code projector as the right and left eyes plane picture projection of unit stereoscopic image projecting device of the present invention, for on both at home and abroad popular, the tactic three-dimensional program source of following form (promptly times field type on, the three-dimensional program of following form), being transported to plane DLP digital projection parts is projected on the screen to tactic up and down, two width of cloth plane pictures of vertical compression, a lens pillar is installed in the appropriate location of the projecting light path before the camera lens of corresponding D LP digital projection parts, the axis of symmetry of column camera lens is parallel with surface level and by projection optical axis and vertical with the projected light axis (promptly about symmetrical), make be projected in the screen on, two width of cloth left sides of following tactic vertical compression, the vertical amplification imaging of eye image, appropriate location on the light path before the column camera lens is equipped with a pair of refracting prisms, this birefringence prism is a symmetric offset spread up and down, each sheet refracting prisms be shaped as rectangle, the axis of symmetry of the close column camera lens in one side that each sheet refracting prisms is thicker, the projection ray that makes the upper image that sees through projection lens is through the suitable angle of the downward refraction of the refracting prisms of top, the downward translation of the upper image of imaging in the screen so; Make the projection ray of the bottom graph picture that sees through projection lens upwards reflect suitable angle through following refracting prisms, the bottom graph of imaging looks like the translation that makes progress in the screen so, making up and down, the right and left eyes projected image image space of format permutation overlaps substantially, respectively the mounted on surface of a pair of up and down refracting prisms a pair of with the refracting prisms shape, the orthogonal polaroid of the corresponding light transmission shaft direction of size, spectators are with the orthogonal polaroid glasses of corresponding left and right sides light transmission shaft direction to separate the right and left eyes stereo-picture automatically, through the image pixel contraposition of the left and right sides of vision system, mathematical logic computing and fusion, spectators projection of sensation stereo-picture is separated with screen, provide more real three-dimensional perfect the enjoyment to spectators.
