The utility model provides a projected image warp and the problem of ghost image, can increase driving safety.
Description
Technical field
This utility model relates to a kind of automobile intelligent new line head up displays, particularly relates to automotive windshield formula head-up display system.
Background technology
In prior art, automobile head up displays (Head Up Display), is called for short HUD, is a kind of electronic display unit being made up of electronic component, display element, control element and power supply etc..It can be projected on shield glass by optics with image, character style, and makes driver just need not to bow in startup procedure it can be seen that information needed.
When driver drives, sight line leaves front, then be the most extremely easily caused the generation of traffic accident.Generally driver bows and reads the information above navigation or mobile phone and at least need the time of 0.5 second, this if there is run at high speed or vehicle relatively more in the case of, easily there is vehicle accident, driving dangerousness improves the most therewith.Automotive windshield formula head up displays has great application market.Recent year some synthesis types automobiles head up displays manufacturing enterprise has carried out the research of automotive windshield formula head up displays correlation technique in succession, and makes some progress.Though required running information (such as navigation information, traffic information, vehicle condition information etc.) can be projected on automobile front windshield by the automotive windshield formula head up displays developed at present; driver is made to obtain in the case of Herba Plantaginis road conditions by head-up display projection information on windshield paying close attention to; but due to different automobile types windshield inclination angle, curved surface inconsistent; frequently can lead to head-up display projection distortion; in use; the problems such as deformation and the ghost image that would generally occur projection picture on front windshield, greatly have impact on driving safety.
Utility model content
The purpose of this utility model is to provide a kind of intelligent automobile windscreen formula head up displays, can effectively solve problems of the prior art, realize driver to need not bow in startup procedure and just can be clearly apparent information needed, and projection picture will not be distorted and ghost phenomena, thus improve drive safety further.
nullThe purpose of this utility model is achieved in that a kind of intelligent automobile windscreen formula head up displays，Including the image control unit being connected with the outfan of car running computer，Described image control unit is powered through SPU，The outfan of image control unit connects image-display units，Image-display units outputs signal to optical projection unit，Projected on automobile front windshield by optical projection unit，Also include image feedback mechanism，Described image feedback mechanism includes optically detecting device、Image conversion unit and data storage cell，Optically detecting device is for gathering the picture signal of projection on automobile front windshield and giving image conversion unit，After the metaboly of picture is eliminated by image conversion unit by the corrected parameter being previously implanted，Output revises signal to described data storage cell，The outfan of data storage cell is connected with the input of image control unit，Image control unit is by revising signal correction image，Again by optical projection unit by revised image projecting to automobile front windshield.
During this utility model initialization, first show through car running computer outfan provide initial pictures, this image because of different automobile types windshield inclination angle, curved surface inconsistent, and cause head-up display projection distortion or distortion, by image feedback mechanism output correction signal to image control unit, then by optical projection unit by revised image projecting to automobile front windshield.Compared with prior art, the beneficial effects of the utility model are: this device can project correcting image on windshield glass, revise that the picture making to be incident upon on windshield glass is undistorted and ghost phenomena by reverse, observe surrounding to driver and provide the most convenient, so that drive safer.
Being as further improvement of the utility model, described optical projection unit includes that surface is coated with the eyeglass composition of reflectance coating, and reflecting mirror is by revised image reflective projection to automobile front windshield.Described lens surface shape can be plane, it is also possible to for arcwall face.The image being incident upon on windshield glass is sampled, is analyzed by described image acquisition units, by contrasting with desired ideal image, calculates the photogrammetric distortion of real image and ideal image；Additionally, make the picture being incident upon on windshield glass that undistorted and ghost phenomena not occur by reverse correction, corrected parameter is saved in data storage cell simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model schematic block circuit diagram.
Detailed description of the invention
nullAs shown in the figure，For a kind of intelligent automobile windscreen formula head up displays，Including the image control unit being connected with the outfan of car running computer，Described image control unit is powered through SPU，The outfan of image control unit connects image-display units，Image-display units outputs signal to optical projection unit，Projected on automobile front windshield by optical projection unit，Also include image feedback mechanism，Described image feedback mechanism includes optically detecting device、Image conversion unit and data storage cell，Optically detecting device is for gathering the picture signal of projection on automobile front windshield and giving image conversion unit，After the metaboly of picture is eliminated by image conversion unit by the corrected parameter being previously implanted，Output revises signal to described data storage cell，The outfan of data storage cell is connected with the input of image control unit，Image control unit is by revising signal correction image，Again by optical projection unit by revised image projecting to automobile front windshield.
In this device, optical projection unit includes that surface is coated with the eyeglass composition of reflectance coating, on reflecting mirror reflective projection to automobile front windshield；Described lens surface shape is plane, it is also possible to for arcwall face.
During initialization, first show through car running computer outfan provide initial pictures, this image because of different automobile types windshield inclination angle, curved surface inconsistent, and cause projection distortion or distortion, by image feedback mechanism output correction signal to image control unit, then by optical projection unit by revised image projecting to automobile front windshield.Revise that the picture making to be incident upon on windshield glass is undistorted and ghost phenomena by reverse, observe surrounding to driver and provide the most convenient, so that drive safer.
This utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in this utility model; those skilled in the art is according to disclosed technology contents; need not performing creative labour and some of which technical characteristic just can be made some replacements and deformation, these are replaced and deformation is all in protection domain of the present utility model.
