Description
Technical field
The invention belongs to emulate Display Technique field, the holographic display system of a kind of identical topography and geomorphology especially set out,
Have very in the place such as operational commanding, virtual reality, smart city, holographic monitoring, Entertainment, display and demonstration
Purposes widely.
Background technology
Sand table is the micro-landscape of outdoor scene, and sand table can be that policymaker shows topography and geomorphology shape the most intuitively, extensively
General it is applied to the fields such as operational commanding, real estate, city planning design, three-dimensional map.Common sand table is by sand
Daughter root is piled up according to the shape of landform, landforms and is formed, and then coated with color, microcosmic view, and then ratio is more fully
Show the view of outdoor scene.The sand table in modern age makes and presents diversified trend, including: timber, plastics, gold
Sand table that the composites such as genus, broadcasting and TV are made and the goods electronic sand map etc. being combined landform curtain by front projection.
In recent years, along with super bright shadow casting technique and the development of multiple cameras image fusion technology, in military field, intelligence
Intelligent city, monitoring field, the most important place, stereo sand table+front projection+holography of monitoring visual fusion in real time is supervised
Control comes into vogue, and monitor in a certain region in the way of getting a bird's eye view in real time is dynamic, compares the monitoring of flat image formula, can
To obtain more intuitively, more real image, have huge side beyond doubt for improving correct judgement rate, correct decisions rate
Help.Realizing holographic monitoring in the way of projection combines 3D stereo sand table, the uneven meeting of 3D stereo sand table makes projection
The focal length of machine cannot accurately focus on, and projection picture contrast under high illumination environment, color saturation are the most also
Cannot overcome, scialyscope light dazzle and high etc. the problem of big, the maintenance cost of taking up room is the most inevitable.
The present invention proposes the manufacture method of the holographic display screen of a kind of identical topography and geomorphology, can be by image from coincideing
Topography and geomorphology is led as the rear projection of screen is to leading as screen is upper and is leading the shadow demonstrating identical topography and geomorphology before as screen
Picture.
Summary of the invention
It is an object of the invention to provide the holographic display system of a kind of identical topography and geomorphology, it is compared to using scialyscope
System, there is higher definition, longer life-span, lower maintenance cost.
The principle of the present invention is to lead as the holography of screen composition system shows with the optical fiber of flat faced display and identical shape of mountain
Show part；The computer graphical that 3D modeling composition system with computer with for the topography and geomorphology specifying region shows
Framework part；Real-time to cover the panorama in the appointment region that the multiple stage specifying region gets a bird's eye view video camera visual fusion
The dynamic image display part of image composition system；The landform that computer 3D models is entered by monitoring visual fusion in real time
Among landforms, the display screen of identical shape of mountain shows, formed for topography and geomorphology to get a bird's eye view formula real-time
Holographic what comes into a driver's.
The present invention includes holographic display unit 1, full scenery picture splicing system 2, splicing framework 3, full what comes into a driver's
The output of image mosaic processing system 2 is connected on holographic display unit 1, and splicing framework 3 is aobvious for fixing holography
Show unit 1.As shown in Figure 1.Wherein, holographic display unit 1 refers in particular to constitute being more than of image displaying part of the present invention
The holographic display unit being stitched together of 1, splicing framework 3 refers in particular to spell one to one with holographic display unit 1
Connecing framework, the connecting method of holographic display unit 1 can be arbitrary, but is with closest for specific landform
The mode of landform ratio combines, to reduce on the combination large-size screen monitors being made up of holographic concatenation unit 1 over the ground as far as possible
The redundancy section of shape figure.
The holographic display unit 1 of the present invention include flat faced display 11, coincide shape of mountain lead as screen 12, strongly
Tensionless winkler foundation adhesive tape 13；Strongly the picture of leading of flat faced display 11 and identical shape of mountain is shielded 12 admittedly by tensionless winkler foundation adhesive tape 13
It is scheduled on together, as shown in Figure 2.The flat faced display 11 of the present invention include LCD liquid crystal display screen, OLED display screen,
QLED display screen, LED display etc..Leading as screen 12 is by fiber optic conduction pixel of the identical shape of mountain of the present invention
Lead as screen, the manufacturing process of its shape include according to shape of mountain arrangement molding and according to shape of mountain carve molding
Two kinds, leading as the forming method of screen 12 is first by the optical fiber reference ZL 2,007 1 of equal length of the shape of mountain that coincide
" guide-lighting image amplifies for 0176399.9 " a kind of high gain transmissive viewing screen " and patent ZL 2,007 1 0176403.1
Screen " method that the proposes optical fiber of equal length is arranged in rectangular shape light is slim, and shape, then use
The method of engraving, by the shape of slim for the rectangle light 3D plastic relief being engraved as and setting, forms the shape of mountain that coincide
Lead as screen 12.
The full scenery picture splicing system 2 of the present invention is to have holographic display unit splicing function, multichannel video camera
The modeling of image co-registration function, specific topography and geomorphology 3D computer graphical and the full scenery picture splicing of output function
System.The image stitcher function of full scenery picture splicing system 2 possesses the merit of normal image splicing device
