Embodiment
Below by embodiment, the invention will be further described, and its purpose is only that the research for more fully understanding the present invention
The protection domain that content is not intended to limit the present invention.
Fig. 1 is a kind of structural representation of HUD by 3D display technology augmented reality of the present invention.Fig. 2 is
The operating diagram of the HUD by 3D display technology augmented reality of the present invention.Fig. 3 is being shown by 3D for the present invention
Show the navigation effect schematic diagram of the HUD of technology augmented reality.Fig. 4 is the optical amplifier and projecting unit of the present invention
Schematic diagram.Fig. 5 is the 3D display unit depth of field of the present invention apart from schematic diagram.With reference to Fig. 1~5 pair technical scheme
It is described in detail.
With reference to figure 1~5, the HUD 10 of the invention by 3D display technology augmented reality includes：Housing 1,3D
Display unit 2, optical amplifier and projecting unit 3 and optical imagery film 4.The 3D display unit 2 and the optical amplifier and
Projecting unit 3 is arranged in the housing 1, and the optical imagery film 4 is arranged at the windshield 5 of automobile.
The 3D display unit 2 is used to provide 3D image strips, and the virtual screen of solid can be presented before driver.
The tridimensional virtual image that the 3D display unit provides includes virtual navigation information.The virtual navigation information includes turning, directly
OK, the arrow information including going up a slope.Specifically, 3D display unit 2 includes 3D LCDs 21, the three-dimensional He of virtual screen 22
The distance l of liquid crystal display plane 21 is the depth of field of tridimensional virtual picture, as shown in Figure 5.
The optical amplifier and projecting unit 3 are amplified and projected on windshield 5 to the 3D image strips.Tool
Body, the optical amplifier and projecting unit 3 can be made up of n optical mirror plane, and the amplification coefficient of optical mirror plane 1 is z1, light
The amplification coefficient for learning minute surface 2 is z2......Optical mirror plane n amplification coefficient is zn, then (that has amplified is vertical for the stereoscopic picture plane projected
Body picture) stereoscopic depth be L=l*z1*z2*…zn.And the eyes (i.e. gaze area) of driver arrive the stereoscopic picture plane of amplification
The depth of field distance of farthest is that the depth of field distance of HUD should meet to be equal to stereoscopic depth L+ mirror image distances.Wherein, mirror image
Distance is the eyes of driver to the stereoscopic picture plane distance most nearby of amplification, and the mirror image distance is by optical mirror plane relative to keeping out the wind
The installation site of glass 5 determines, and is changeless after installing.That is, can be by adjusting 3D display unit 2
Tridimensional virtual picture depth of field l, to adjust the stereoscopic depth L of the stereoscopic picture plane amplified, so as to adjust the relief painting of amplification
The depth of field distance in face.For example, if the depth of field distance between the eyes and real road of driver were 10 meters or so, mirror image distance
2 meters can typically be accomplished, then (can be zoomed in or out vertical by the depth of field l for the tridimensional virtual picture for adjusting 3D display unit 2
Body virtual screen) L is adjusted to 8 meters or so, so that tridimensional virtual scene and actual scene (such as the actual road of projection
Face) (farthest of the tridimensional virtual image amplified is substantially at same plane with actual road surface) suitably, is fully coincide,
So as to realize the effect for strengthening reality.
The optical imagery film 4 is used to be imaged the 3D image strips of amplification, realizes tridimensional virtual image and reality
Road surface is combined.
The tridimensional virtual image provided below the 3D display unit in the present invention illustrates.The tridimensional virtual image is
Real time image collection by camera to front road conditions, and image recognition, analysis are carried out by image recognition technology road pavement
Go out shape, bending curvature, track, angle of turn and radius, the angle of inclination information on road surface, calculate road surface model, further according to
The data such as map datum parameter that navigation engine provides, direct of travel, distance, calculate the road surface and track to be walked.Again
The realtime graphic that virtual navigation image gathers with camera combines, there is provided gives car owner's most intuitively navigation instruction.Vehicle-mounted
After virtual navigation configured information is output to HUD by navigation host, HUD is by the virtual navigation configured information
Project on windshield, realize the virtual navigation information superposition to the effect on actual road surface.
In this way, the tridimensional virtual image including navigation configured information can be kissed completely with actual road surface
Close, driver when steering wheel is held, can clearly, it is direct, effectively obtain direction of advance, realize the effect of augmented reality
Fruit.
As shown in figure 3, virtual navigation instruction directly will be superimposed with road surface, the effect of augmented reality, driver's observation are played
Road surface is with regard to that can be easy for that the direction travelled can be judged, without missing crossing.
Obviously, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Invention, and be not used as limitation of the invention, as long as in the spirit of the present invention, to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
