Description
Technical field
The invention belongs to vehicle-mounted HUD technique of display field, particularly relate to a kind of HUD read out instrument in conjunction with voice and video identification.
Background technology
HUD (Heads Up Display) new line numerical monitor, be head-up display system again, it can important information, as rotating speed, navigation, time, the small screen utilizing the principle of optical specular reflection to project automotive windshield or to erect allows people feel, and image is in the distance in several meters, headstock front, chaufeur need not be bowed, just can see important information clearly.Also have and add lens on the basis of original Windshield imaging, the content of display is amplified to farther place, chaufeur can not regulate the focal length of sight line in the process of moving, parallelly while seeing surface conditions clearly forward sees the vehicle condition information that HUD shows.
Existing HUD display system only cannot can show limited content in conjunction with actual environment, and the content that chaufeur can not show with HUD is in the process of moving carried out effectively mutual and controlled.Respond HUD displaying contents as needed chaufeur and sight line must leave front, manually contact associative operation interface, makes chaufeur apply this system and is subject to limitation, is difficult to ensure driving safety.
Summary of the invention
In order to overcome the problem of the deficiencies in the prior art, HUD display system only cannot can show limited content in conjunction with actual environment, the content that chaufeur can not show with HUD is in the process of moving carried out effectively mutual and is controlled, respond HUD displaying contents as needed chaufeur and sight line must leave front, manual contact associative operation interface, make chaufeur apply this system and be subject to limitation, be difficult to ensure driving safety, the invention provides a kind of HUD read out instrument in conjunction with voice and video, in order to solve technical matters of the prior art.
The technical scheme that the present invention provides for achieving the above object is: a kind of HUD read out instrument in conjunction with voice and video identification, having the HUD module for being projected by information of vehicles on vehicle front windshield, also comprising:
Photographing module, for taking the image of vehicle and driver status, and is converted into picture signal by image;
Voice for recording the voice of chaufeur input, and are converted into voice signal by voice module;
Circuit module, the integrated GPU of described circuit module, arm processor, acceleration pick-up, GPS sensor, wireless WIFI and bluetooth module, the picture signal that wherein GPU acquisition photographing module transmits is mated with prearranged image signal, the voice signal that arm processor identification microphone gathers the transmission of sample sound acquisition voice module mates with default voice signal, obtains the action command matched; The gesture that chaufeur is taked by arm processor, the action of eyes, or the voice of typing carry out identification and obtain action command and automatically perform this action, the relevant data of mobile phone are obtained by WIF or bluetooth, other sensor states of combined circuit module, as GPS sensor, acceleration pick-up, forms the interface of final display, is projected in HUD module be shown to chaufeur by projection module.
Further, chaufeur carries out interaction by this HUD read out instrument and automobile, takes gesture motion to be one of identifiable design action of this HUD read out instrument internal preset, analyzes for circuit module to gesture motion; The voice gathered are the voice signals comprising voice activation word, and sound identification module carries out Eigenvalues analysis to voice.This HUD read out instrument finally obtains the action command matched in conjunction with the result of gesture and voice.
Further, described photographing module is by CSI interface, or MIPI video interface, or bnc interface, or USB interface, or wireless module and circuit module are electrically connected, and this photographing module comprises: colour imagery shot and infrared camera.Colour imagery shot is arranged on Windshield dead ahead, for taking the ambient condition of vehicle periphery; Infrared camera takes the profile of chaufeur gesture and the eyes frequency of wink for analyzing tired driver state in the face of chaufeur is arranged.
Further, colour imagery shot shooting surrounding environment state include but not limited to, front truck crossroads traffic light situation, leading vehicle distance, pedestrian's situation, the every data arm processor collected according to the set and display of different scene at HUD display module.
Further, all sides of described infrared camera have LED infrared light supply, LED infrared light supply initiatively sends infrared ray, utilize CCD or CMOS in infrared eye can experience the spectral characteristics of the infrared light that surrounding scenes and Ambient are returned, coordinate infrared lamp to realize night vision monitoring as " light source ".Infrared camera gathers the contour image of gesture and the motion image of eyes is RAW optical signalling, and RAW optical signalling is converted to after digital signal through A/D converter, and GPU digital signal being sent to circuit module carries out Modulation recognition and instruction identification.One infrared perspective layer is also set below LED infrared light supply, for intercepting visible ray and eliminating visible ray to the interference of video identification.This infrared absorption filter photosphere can be made up of saturating infrared polycarbonate, also can be made up of saturating infrared acrylic, also can be made up of the saturating infrared fileter of plastics.
