Description
Technical field
It the utility model is related to data presentation technique field, and in particular to a kind of CAVE using small spacing LED screen shows
Show system.
Background technology
CAVE systems can apply to any virtual emulation application field with feeling of immersion demand.For example, virtual design
Virtual to demonstrate with manufacture, collaborative planning etc., application is quite varied.In existing most of CAVE systems, virtual display space
Wall be generally made up of back projection wall.The display of above ground portion, can also be above display space except that can carry out rear-projection
Projector is disposed to ground.And with the development of technology, also occur by LCD 3D mosaic screens or large-scale LCD 3D
Screen replaces the technology of Projection Display.
Two kinds of common CAVE systems in the prior art.
(1) the CAVE systems based on back projection wall
By more than 3 faces (containing 3 faces), hard back projection wall forms CAVE system virtualizations display space.System utilization is more logical
Road what comes into a driver's simultaneous techniques, whole three-dimensional scenic content is shown in projection wall.Subscriber station wears use in virtual display space
In the empty frames glasses of viewing shadow wall three-dimensional imaging, infrared markers point is adhered to wherein on empty frames glasses.At the angle of virtual display space
Fall upper to place infrared camera respectively.Due on empty frames glasses the position of human eye of the position of infrared markers point and user at a distance of not
Greatly, the specification of whole system is contrasted, can be ignored, so as to which system utilizes the position of infrared camera acquisition infrared markers point
Parameter is to obtain the location parameter of user's eyes.System according to user's eyes location parameter of acquisition, adjustment shadow wall image with
With user viewing current location (such as：It will amplify from the nearly picture of shadow wall, will be reduced from the remote picture of shadow wall).And with reference to
Picture calibration system, the picture at knuckle is calibrated, display image is not produced distortion.
(2) the CAVE systems based on LCD 3D mosaic screens or based on large-scale LCD screen
The technical principle and technology (one) are basically identical, but virtual display space is substituted for LCD 3D by back projection wall and spliced
Screen or large-scale LCD screen form (except ground screen), and change over render pipeline and splicing device that display matches.
However, CAVE systems of the prior art have the following disadvantages：
Being made up of the CAVE systems virtually shown in technology (one) back projection wall needs in the dark ability of environment it is clear that to ring
Environmental light requires high.And the color saturation of display picture is not high, and viewing effect is bad.Projector's life-span is shorter.
CAVE systems in technology (two) based on LCD 3D mosaic screens or based on large-scale LCD screen, although compared with back projection
Wall need not have too high requirement to ambient light, and color saturation is also higher, but long-term use of, can cause brightness between unit
Decay with color inconsistent and irrecoverable.In addition there is physics piece between LCD screen, influence viewing effect.Large-scale LCD screen
The problem of bad transport also be present.
With the raising of display screen manufacturing technology, there is small space distance LED display screen.The small autologous hair of space distance LED display screen
Light, do not limited by ambient light；Display picture color saturation is high, splices that seamless, service life is long, detachable good between display screen
Transport.If it can be applied in CAVE systems, it is possible to greatly reduce the limitation that various terminals are shown in existing CAVE systems
Property.
