Description
Technical field
The invention belongs to the HUD of vehicle-mounted HUD display technology fields, more particularly to a kind of identification of combination voice and video to show
Device.
Background technology
HUD (Heads Up Display) new line numerical monitor, is called head-up display system, it can be important letter
Breath, such as rotating speed, navigation, time, using the principle of optical specular reflection project automotive windshield or erect come the small screen on allow
People feels that image is in several meters of distance, driver is bowed, with regard to that can see important information clearly in front of the headstock.Also have
Lens originally are added on the basis of windshield imaging, the content of display are amplified to farther place, driver is running over
The focal length of sight can not be adjusted in journey, the parallel situation of remote seen HUD and shown while seeing surface conditions clearly forward.
Existing HUD display systems can not be only capable of displaying limited content with reference to actual environment, and driver is running over journey
In the content that can not be shown with HUD effectively interacted and controlled.Such as need driver respond HUD display contents must sight leave
Front, manual contact associative operation interface so that driver is using the system by limitation, it is difficult to ensures driving safety.
The content of the invention
The problem of for overcome the deficiencies in the prior art, HUD display systems can not be only capable of displaying limited with reference to actual environment
Content, the content that driver can not show with HUD in the process of moving effectively interacted and controlled, and such as needs driver to respond
HUD display contents must sight leave front, manual contact associative operation interface so that driver is limited to using the system
Property, it is difficult to driving safety is ensured, it is existing to solve the invention provides a kind of HUD display devices of combination voice and video
Technical problem in technology.
The present invention is that the technical scheme for reaching above-mentioned purpose offer is：A kind of HUD of combination voice and video identification is shown
Device, have and be used to projecting information of vehicles into the HUD modules on vehicle front windshield, in addition to：
Photographing module, picture signal is converted into for shooting the image of vehicle and driver status, and by image；
Voice module, for recording the voice of driver's input, and voice is converted into voice signal；
Circuit module, the circuit module integrate GPU, arm processor, acceleration transducer, GPS sensor, wireless
The picture signal that WIFI and bluetooth module, wherein GPU obtain photographing module transmission is matched with prearranged image signal, at ARM
The voice signal that reason device obtains voice module transmission is matched with default voice signal, the action command to be matched；ARM
The voice of gesture that processor takes driver, the action of eyes, or typing is identified to obtain action command and automatic
The action is performed, the related data of mobile phone, the GPS sensor of combined circuit module, acceleration sensing are obtained by WIF or bluetooth
Device state, the interface finally shown is formed, is projected to by projection module in HUD modules and is shown to driver.
Further, driver is carried out interactive by the HUD display devices and automobile, and it is that the HUD shows to take gesture motion
One of recognizable action of showing device internal preset, gesture motion is analyzed for circuit module；The voice of collection is bag
Voice signal including word containing voice activation, sound identification module carry out Eigenvalues analysis to voice.The HUD display devices are final
The action command to be matched with reference to the result of gesture and voice.
Further, the photographing module passes through CSI interface, either MIPI video interfaces or bnc interface, or USB
Interface, or wireless module are electrically connected with circuit module, and the photographing module includes：Colour imagery shot and infrared camera.It is color
Color camera is arranged on immediately ahead of windshield, for shooting the ambient condition of vehicle periphery；Infrared camera faces driver
The profile of shooting driver's gesture and the eyes frequency of wink for analyzing tired driver state are set.
Further, the state of colour imagery shot shooting surrounding environment includes but is not limited to, front truck crossroads traffic light situation,
Leading vehicle distance, pedestrian's situation, each item data arm processor collected are shown in HUD according to the setting of different scenes and show mould
Block.
Further, the week side of boss of the infrared camera has LED infrared light supplies, and LED infrared light supplies actively send infrared
Line, the spectrum for the infrared light that surrounding scenes and Ambient are returned can be experienced using the CCD in infrared eye or CMOS
Characteristic, infrared lamp is coordinated to realize night vision monitoring as " light source ".The contour image and eyes of infrared camera collection gesture
Motion image is RAW optical signallings, and RAW optical signallings send data signal to after A/D converter is converted to data signal

The gesture or eye image of infrared shooting carry out background separation, for eliminating influence of the background to graphics filter；By background point
Image from after is classified with pre-set image contrast；Sorted picture is carried out according to the movement locus of gesture or eyes
Instruction identification, determine the action command that movement locus represents.
Further, HUD modules include optics and show structure, projection module, wherein optics show structure include it is positive throw into
As film and optical lens, projection module is based on micro- throwing module with DLP technologies or micro- throwing module based on laser projection
Or the LCD screen of high brightness；Projection module projects the positive throwing imaging film of relative projection module by being imaged, and positive throw is imaged
Film be exactly on the surface of film using chip typography in printed thereon close to the convex surface more than more than 100,000 of Nano grade
Structure, then nano level light sensitive layer is coated with by vacuum magnetron sputtering coating film technique, ensure have very well to projecting to imaging film
Diffusing reflection effect but also with high optical gain.It is positive to throw imaging film again by imaging line reflection to the HUD for just throwing imaging film relatively
On the optical lens of module, driver can see that projection module sends light through the optical lens before windshield
It is ultimately imaged.
Further, the optical lens two sides has identical curvature, and thickness is consistent, and the reflectivity of intrados plated film
Higher than the reflectivity of extrados plated film, such as：The reflectivity of intrados is 30%, the reflectivity 1% of extrados, ensures that driver sees
Have the normal images of 70% light transmittance outside car, and on just saturating imaging film into the picture light that can have 30% on intrados reflex to
Driver's eyes, possesses the effect for zooming into the virtual image.
Further, HUD modules are suspended on below the sunshading board of position of driver or immediately ahead of console.
Further, automobile or intelligent terminal can pass through controlled in wireless HUD display content.User passes through on automobile
Button or intelligent terminal communicated by the HUD modules of car networking and automobile, the content shown by HUD can be adjusted.
The beneficial effects of the invention are as follows：Compared to current vehicle-mounted HUD Display Technique, the present invention has advantages below：
1st, the content that HUD is shown by the data extreme enrichment of voice and acceleration transducer etc..
2nd, driver by the HUD content sights that show of viewing without departing from road surface, can obtain in time safely vehicle and
Peripheral information, human-computer interaction are rapid convenient.
3rd, for driver by carrying out information exchange with vehicle-mounted HUD systems, traffic information is shared in networking, improves traffic traveling
Efficiency.
