Abstract
The invention discloses a three-dimensional space imaging projection device, comprising a screen and a regular triangular pyramid. The video image on the screen is mapped into the air inside the triangular pyramid based on the specular reflection principle, so that the feeling of the three-dimensional image is generated in the human brain in combination with the rotation of the video image content. The three-dimensional space imaging projection device is very simple in structure, high in luminance, simple in process, very high in three-dimensional imaging quality, and suitable for exhibition and advertising industries.
Description
Technical field
The present invention relates to the 3D hologram technical field of imaging, particularly relate to three dimensions imaging grenade instrumentation.
Background technology
The 3D display technique has had the development course of last 100 years, and as far back as 1903, scientist found the principle of " parallax is created three-dimensional ".The 1950's, the color TV technical development is to approaching the practical stage, and " three-dimensional minute picture TV tech of complementary colors " begins to be applied to stereotelevision.Basic skills is to remove to take the Same Scene image with the video camera that two camera lens front ends install optical filtering additional, spectators see on the screen of colour television set is that the image of two secondary different colours is superimposed mutually, just can see three-dimensional television image when spectators observe by corresponding optical filtering.
The 3D display technique is in the develop rapidly stage at present, has a variety of display techniques to occur.Can be divided on the large direction and can be divided into technically bespectacled technology and not bespectacled 3D display technique.Need bespectacled technology to be divided into: active-shutter and polarization type 3D technology, but for beholder especially friend with regard to wearing glasses itself, it is very inconvenient to use.Not bespectacled technology can be divided into: plane three-dimensional display technique, body 3-D technology.
The plane three-dimensional display technique can be divided into optical barrier type (Barrier), lens pillar (Lenticular Lens) technology and point to light source (Directional Backlight) three kinds.These three kinds of technology disadvantage are in order to guarantee viewing effect, and the position at beholder place must be over against screen, and eyes also will keep level with screen.3D display frame is watched and can not that works when watching the 2D picture be indiscriminately ad. as one wishes selected multi angle view in the past.
The body 3-D technology substantially can be divided at present rotary scanning type and show that (swept-volume display) and solid bodies show (solid-volume display) two kinds.Wherein the former representative be Perspecta and Felix3D and the latter be represented as Depth Cube.The advantage of these technology maximums is constraints of having broken away from glasses, but rotary scanning type body three-dimensional stereo display technique low cost of manufacture, simple in structure but exist at present many insoluble problems: low such as brightness, freedom from vibration is poor and be not suitable for giant-screen application scenario etc.Also there are a lot of deficiencies at aspects such as resolution, visible angle and visual ranges.
Above invention has high cost, and size is restricted, and angular field of view is narrow, can not make the large three-dimensional display apparatus of square level
Summary of the invention
For dumb on the size that overcomes above-mentioned prior art, with high costs, and display effect is poor, brightness waits not enough not, the invention provides a kind of three dimensions imaging grenade instrumentation, comprise: the first screen 1, the first reflecting surface 6, the second screens 2, the second reflecting surface 5, the 3rd screen 3, the three reflectings surface 4, light source 7.
According to a further aspect of the invention, described first shields 1, the second screen 2, the 3rd screen 3 can adopt the LCD liquid crystal display, PDP display, LED screen or projector's screen, the first reflecting surface 6, the second reflectings surface 5, and the angle of the side of the 3rd reflecting surface 4 and bottom surface is 45 degree, all reflectings surface can adopt single-layer and transparent or partially transparent reflectance coating, glass, organic glass, holographic film, perhaps other transparent or part transmission material are made, and light source 7 can adopt the LED lamp, shot-light, perhaps common bulb.
According to a further aspect of the invention, the first reflecting surface 6, the second reflectings surface 5, the 3rd reflecting surface 4 is three sides of positive triangular pyramid, and the first screen the 1 and first reflecting surface 6 angles are 45 degree, the second screen the 2 and second reflecting surface 5 angles are 45 degree, and the 3rd screen the 3 and the 3rd reflecting surface 4 angles are 45 degree.
This technology is utilized transparent or partially transparent reflecting surface reflection and transmission theorem exactly, and the three-dimensional digital model that rotates is projected on spectators' the retina, allows the audience's feeling arrive real three-dimensional and experiences.Do not need wears glasses, angle of visibility is very wide, the degree of 360 about can reaching, the up and down visual range of 120 degree.Our technology can allow the display device cost of manufacture very low in addition, and it is very flexible that size is how done, and is all very flexible to the huge display device that is made into the square level from 6 cun skinny devices.
Compared with prior art, the invention has the beneficial effects as follows on the size that cost is low flexibly, display effect is good, high brightness, and display area is large, and can also support audio function.

Embodiment
The present invention is further described below in conjunction with accompanying drawing.
As shown in Figure 1, three dimensions imaging grenade instrumentation comprises three triangle display screens and three triangle reflectings surface, forms the different display system of three cover directions.The first display system comprises: the first screen 1, the reflecting surface 6.The second display system comprises: the second screen the 2 and second reflecting surface 5.The 3rd display system comprises: the 3rd screen the 3 and the 3rd reflecting surface.
Described the first screen 1, the second screen 2, the three screens 3 can adopt the LCD liquid crystal display, PDP display, LED screen or projector's screen.The first reflecting surface 6, the second reflectings surface 5, and the transparent or partially transparent material of the 3rd reflecting surface 4 employings can be films, or glass, organic glass.
As shown in Figure 2, the three-dimensional perspective projection resolution on three angles of object is presented on the first screen 1, the second screen 2, the three screens 3.These three angles are respectively 0 degree, 120 degree, 240 degree.
As shown in Figure 3, take the first display system as example, first the screen 1, with the first reflecting surface 6 angles be 45 the degree.The skeleton view of three-dimensional body is presented at the position of A on the first screen 1, and according to principle of reflection, by reflecting surface 6, its virtual image meeting appears at the B position.By this principle, add the effect of perspective projection, people and high-quality stereoscopic sensation are given in the virtual image that demonstrates 3-D view that can be very true to nature.
