Description
Technical field
The present invention relates to HUD technical field more particularly to a kind of AR-HUD light path systems of convertible adjusting.
Background technique
AR-HUD (Augmented Reality-Head Up Display, augmented reality head up display) will increase at present
Strong reality is combined with head up display, is used primarily in the auxiliary driving procedure of automobile.For the angle of software, in order to subtract
The algorithm difficulty that small reality is merged with virtual image, it is desirable that the picture position of projection remains stationary, so eyeglass does not allow to overturn
(movement that overturning will lead to image planes) directly results in needed for eyeglass due to needing to meet the height requirement of different drivers again
Area increases, this is also one of the main reason for causing AR-HUD volume excessive.And the eyeglass of AR-HUD is than common HUD's
Greatly, and projector distance is remote, and more sunlight is caused to be gathered on image source by imaging lens, and the heat of generation is extremely easily damaged picture
Source part.
Higher and higher to interior space status requirement if AR-HUD optical path volume is excessive, space is limited in the car
In the case of, AR-HUD volume is the smaller the better, so how to reduce AR-HUD under conditions of guaranteeing the imaging of preferable augmented reality
Volume at key.Meanwhile preventing image source component from damaging because of the heat that solar ray collecting generates is also an emphasis.

In order to solve the above technical problems, the present invention provides a kind of AR-HUD light path system of convertible adjusting, including generates
Image source display module, optical path adjusting mould group and the windshield of AR-HUD optical path, the optical path adjusting mould group are equipped with the first reflection
Mirror and the second reflecting mirror；First reflecting mirror and second reflecting mirror are the reflecting mirror or described that may be reversed and adjust
First reflecting mirror is static reflecting mirror and second reflecting mirror is that the reflecting mirror adjusted may be reversed.
Preferably, first reflecting mirror and second reflecting mirror be free-form surface mirror or it is a piece of for from
By curved reflector and another is plane mirror.
Specifically, the flip angle state of first reflecting mirror and second reflecting mirror according to the height of driver and
Setting.
In more preferably embodiment of the invention, the image source display module includes that projection light machine, diffuser plate and projection are adjusted
Save mirror.
Preferably, the projection light machine uses DLP, LOCS, LCD or Color Laser Projection Technology.
Preferably, it is plane mirror or curved reflector that the projection, which adjusts mirror,.
Specifically, after the picture that the projection light machine projects adjusts mirror reflection by the projection, it is shown in the diffusion
On plate, the picture shown on the diffuser plate reaches second reflecting mirror by first reflecting mirror reflection, further across anti-
The effect of penetrating reaches the windshield, and the projection virtual image is formed in front of driver.
In another embodiment of the invention, the image source display module includes illuminating optical wand, TFT screen, on the TFT screen
The picture of display reaches second reflecting mirror by first reflecting mirror reflection, keeps out the wind further across described in reflex arrival
Glass forms the projection virtual image in front of driver.
A kind of AR-HUD light path system of convertible adjusting provided by the invention, optical path adjusting mould group is using turnover the
Two-mirror greatly reduces the required usable floor area of eyeglass, and (projection adjusts mirror) containing a face reflecting mirror is used in image source display module
With the projecting light path that turns back, keep whole optical path more compact, to greatly reduce the volume of AR-HUD, in FOV, projector distance parameter
When identical, which is far smaller than other not turnover AR-HUD volumes.Image source display module uses Projection Display
Mode, i.e. the picture of projection light machine, which is projected on diffuser plate, to be shown, and diffuser plate high temperature resistant, and sunlight is effectively avoided to focus and damage picture
Source part.
Meanwhile the horizontal FOV of the light path system>10 °, vertical FOV>3.3 °, projector distance>7.5 meters, play augmented reality
Effect adjusts the overturning of convertible reflecting mirror in use, driver can determine to select one such state according to itself height
Angle selects suitable viewing projection virtual image position, there is good augmented reality to assist driving experience.
