Abstract
The invention discloses a double-optical-machine three-dimensional protection display method and system based on chromatographic separation. The system comprises a double-optical-machine protection system of an LED (Light-Emitting Diode) light source, a chromatographic separation filter and a pair of glasses corresponding to the wave band of the chromatographic separation filter. By adding a specific filter into a double-optical-machine optical system, two projected images are non-overlapped specific spectra; the two filtered projected images are reflected by a projection curtain or a white wall, the audience wear filter glasses of a corresponding wave band, one image enters the left eye while the other image enters the right eye, and two images with parallax signals form a three-dimensional image in the brain. Compared with the conventional active three-dimensional display technology, the display method and system have the advantages that the glasses do not need to be charged, and pictures do not flash. Compared with a passive three-dimensional display technology, the display method and system have the advantages that a special metal curtain is not needed, the curtain cost is saved, and installation and application become easier.

Background technology
Stereo projection display technology is that two overlapped images are projected in screen by stereo projecting equipment, makes beholder can experience the depth feelings of image.Project to two width images in screen, a width is received by left eye, and another width is received by right eye, the two width different images that receive by right and left eyes, and synthetic stereo image in brain, makes beholder experience the stereoscopic sensation of picture.To have cost low because of it for stereo projection display technology, and the advantages such as large scale, are widely used in the fields such as film, game, education, commercial affairs, mobile phone, and developed into a kind of mode of people's life, amusement.
Stereo projection display technology be according to wearing spectacles can be divided into spectacle and bore hole formula, due to bore hole stereo display technique exist at present resolution low, watch the shortcomings such as visual angle is little, be not also used widely.Therefore, the stereo display technique of main flow mainly contains three classes: aberration formula, passive polarization type, active-shutter.
Chromatographic resolution formula stereo display technique is a kind of of aberration formula stereo display technique.Chromatographic resolution filter plate is to utilize the characteristic manufacture of photonic crystal to form.Photonic crystal is the material that the material by different refractivity rearranges according to certain rule, wherein 1-D photon crystal has a wide range of applications, for example, be used to comprehensive high-efficiency reflective mirror, ultra-low loss waveguide, nonlinear optics diode, optical switch, optical limiter, second harmonic generator, Photonoc band-edge generator.Chromatographic resolution filter plate is divided into projection light source without the different-waveband overlapping, and in three-dimensional display system, by two different camera lenses, projects, and after selecting to pass through again after reflection, enters viewing person's eyes by chromatographic resolution glasses, forms stereopsis in brain.
Chromatographic resolution formula stereo display technique, more traditional active stereo display technique, glasses are without charging, and picture flicker free; Compared with passive stereo display technique, without special-purpose metal curtain, save curtain cost, and more easily install and use.Advantage due to its integrated initiatively stereo display technique and passive stereo display technique, is widely used at aspects such as large-scale movie theatre, advertising, product introduction and home entertainings.
Summary of the invention
The object of the invention is to adopt chromatographic resolution formula stereo display technique, having made up stereo display technique initiatively needs the shortcoming of the aspects such as charging, film flicker, glasses be expensive and the shortcoming that passive stereo need to be used special metal curtain at glasses.It is a kind of simple in structure, stereo projection display system of conveniently installing and using.
To achieve these goals, the present invention realizes by the following technical solutions:
Two ray machine stereo projection display method and system based on chromatographic resolution, comprise two ray machine optical projection systems, chromatographic resolution filter plate of LED light source, corresponding to the glasses of chromatographic resolution filter plate wave band.By add specific filter plate in two ray machine optical systems, making two images of projection is non-overlapping special spectrum; Filtered two projects images are after projection screen or white wall reflection, viewing person wears the filtering glasses of corresponding wave band, make wherein piece image enter left eye, another piece image enters right eye, and the image that two width have parallax signals forms stereopsis in brain.
As further scheme of the present invention, described ray machine is projector ray machine.
As further scheme of the present invention, the light source in described ray machine is LED tri-looks (red, green, blue) light sources, but is not limited only to LED three-color light source, also can be LED white light source, mercury lamp light source, LASER Light Source or other light source of projector.
As further scheme of the present invention, the quantity of described ray machine is two.
As further scheme of the present invention, described chromatographic resolution filter plate is that the wavelength of projection light source is divided into two wavelength band in left and right according to transmitance peak value.Left wave band image projects by a ray machine, and right wave band image projects by a ray machine.
As further scheme of the present invention, described projection screen is common projection screen or white wall.
As further scheme of the present invention, described filtering glasses are the filtering glasses corresponding with chromatographic resolution filter plate wave band, and every eyeglass can only be by the projection image of a certain camera lens from ray machine.
Two ray machine stereo projection display method and system based on chromatographic resolution, comprise the following steps:
(1) chromatographic resolution filter plate is installed at light source of projector position, this filter plate is arranged between digital micro-demonstration eyeglass and light source, and this light source can be, three-color light source separately, or the white light source of three-color light source after synthetic, or be only white light source, or be other projection light sources;
(2) image of latter two different-waveband projects through two ray machines after filtering;
(3) projection image is through common curtain and white wall reflection;
(4) viewing person wears the filtering glasses of corresponding wave band, makes wherein piece image enter left eye, and another piece image enters right eye, and the image that two width have parallax signals forms stereopsis in brain.
In sum, the present invention compares with conventional art and has following beneficial effect:
Display packing of the present invention and system, more traditional active stereo display technique, glasses are without charging, and picture flicker free; Compared with passive stereo display technique, without special-purpose metal curtain, save curtain cost, and more easily install and use.
