Description
Technical field
The present invention is relevant a kind of optical system framework, particularly relevant a kind of multi-pass new line display that is applicable to portable carrier.
Background technology
New line display (Head Up Display, HUD), it is the flight supplementary instrument that is implemented in the earliest on the aircraft, can allow the driver not need to bow just can to see information on the instrument, interrupt and lose the grasp of state being realized (Situation Awareness) to avoid notice, because use the new line display not only to have convenience and can improve flight safety, therefore can use on any portable carrier, singly be not that airliner can use, even automobile and boats and ships also can use.
Yet, new line Presentation Function of the prior art in the past, all be the simple instrumented data information that some minimum indication range areas are provided in driver's visual line of sight, the demonstration information for example guiding of carrier working temperature, engine speed, speed per hour or some small arrows shows etc.; Nowadays; progress along with Technology Times; the driver can have more other polynary selections; the new line display can also show tire pressure; gearshift is pointed out or is turned to; the reversing prompting; the barrier caution; flying height; flying speed; the course; vertical speed rate changes; any relevant portable carrier such as craft inclination angle and wind direction information is advanced or the relevant portable carrier such as idling institute palpus information; but all be to belong to the single light path display as can be known with present any new line display on the market just; want this cover single light path display and instrument desk to be done a device integration in fact and be not easy; because the new line display is volume required excessive concerning the former instrument desk of having filled electric wire and joint; and according to optical imaging concept as can be known; use any lens or face mirror no matter be; the input image; imaging area all and lens; the optical element dimension size of face mirror is proportional; discuss based on projection quality still more; the optical element dimension of new line display also should not be dwindled again; therefore in the driving cabin of limited space, want to accomplish that large video picture area can be described as is very difficult to implement; moreover the too small video picture information of display area scope also only can allow the driver use remaining light to take a glance at momently instrument control platform; therefore the driver still can't can filter out important crucial information immediately; if the driver too carefully is careful the crucial information of new line display, easily takes sb's mind off sth on the contrary and make the driver crisis-ridden.
In view of this, the present invention be directed to above-mentioned problem, a kind of multi-pass new line display is proposed, the size that not only can have the optical element of direct minimizing lens or face mirror, having more large tracts of land video picture scope, is a kind of high-order multi-pass new line display that has the Mobyneb of safety and efficiency concurrently.
Summary of the invention
Fundamental purpose of the present invention, that a kind of multi-pass new line display is being provided, utilize the multi-pass apparatus structure that image is cut or producing at least two input images with a plurality of visualization unit is aided with the technological means of again compiling video picture again, can make the present invention directly reduce the size of the optical element of lens or face mirror, have more large tracts of land video picture scope, the information picture that the multi-pass display device provides can be fully superimposed with extraneous scene or be made the corresponding scene of information picture do the collocation demonstration, can help the driver to note the crucial information of required portable carrier, the single light path display only can be with the disappearance of small size scope demonstration in the past with effectively solving.
Another object of the present invention, that a kind of multi-pass new line display is being provided, compiled video picture with multi-pass structure generation at least two input images, and the adjustability by the perspective plane mirror can be adjusted suitable angles of display at any time along with height and the sitting posture driven, the single light path display that adopted compared to the past, the present invention more can provide the condition of road surface that the driver is absorbed in the place ahead and the comfort level of driving.
In order to achieve the above object, the invention provides a kind of multi-pass new line display, comprising: at least one visualization unit, to produce at least two input images; A plurality of relay lenss, the refraction angle of capable of regulating input image receives and transmission input image so that difference is corresponding; One virtual image generation unit can correspondingly respectively receive the input image and produce a plurality of virtual images; And a plurality of perspective plane mirrors, receive the virtual image and be reflected into a large tracts of land virtual image with corresponding respectively.
Beneath by the appended graphic in detail explanation of specific embodiment cooperation, when the effect that is easier to understand purpose of the present invention, technology contents, characteristics and reaches.
