The most common form of real world devices is head-up display (HUDs), for the helmet of fighter-pilot or tank driver,
To check various information while checking landform or object.In recent years, start to be applied to show on automobile front windshield
Show the information such as speed.Another example using augmented reality is the wearable glasses of " Google Glass " type.When user wears
When upper augmented reality device, the effect of true picture and virtual image overlapping is visually experienced simultaneously, and it is existing to reach enhancing with this
Real purpose.
Attached drawing 1 is traditional eyewear formula augmented reality schematic device.Traditional eyewear formula augmented reality device includes for giving birth to
At the projector 2' of image, the transparent prism 3' of eyes of user is reached for reflecting virtual image, frame 1' is for fixed projection
Device 2' and transparent prism 3' is to reflect the eyes that virtual image reaches user, so that user can while observing true picture
To observe the virtual image reflected by transparent prism 3'.
However, traditional eyewear formula augmented reality device passes through transparent rib due to the projection arrangement 2' planar virtual image generated
The reflection of mirror 3', when user watches the scene of real world attentively, user cannot watch the virtual image of generation simultaneously.In addition, by
In having used transparent prism 3', traditional eyewear formula augmented reality device has certain volume and weight, is not easy to wear and outer
It sees more general glasses or sunglasses is more clumsy.
Further, since projection arrangement 2' and transparent prism 3' are placed on the front of one eye eyeball, eyes watch image
Shi Jiwei is inconvenient.To solve this problem, Binocular displays mode can be used, but will appear weight and volume increase, it is difficult to is long
The problem of time wears.
Summary of the invention
According to technical problem set forth above, the present invention provides a kind of augmented reality device with depth of field regulatory function.
The technological means that the present invention specifically uses is as follows:
A kind of augmented reality device with depth of field regulatory function, which is characterized in that including can directly be worn for user
Frame mounting, there is on the frame mounting eyeglass, at least one is fixed on the frame mounting for generating virtual graph
The projection arrangement of picture is inlaid at least one in the eyeglass for the depth of field that the virtual image reflexes in user's eye and adjusts dress
It sets, the depth of field regulating device is made of the metal foil material of high reflectance.
The depth of field regulating device can be rounded or oval according to lens shape.Theoretically, the shape of depth of field regulating device
Shape should be round, practical in view of factors such as optical distortions, and it is most appropriate to be designed as elliptical shape.The reason is that, being taken for user
Band is convenient, the depth of field regulating device that depth of field regulating device is embedded in eyeglass, and is embedded into lens according to the incidence angle of light and
The difference of lens index can generate deformation.Therefore, the present invention is using oval design, elliptical shape and optical deformation
It is contrary so that the shape of depth of field regulating device is approximately round in visual effect.
The size of the depth of field regulating device is in 50-700 μ m.It is true that user's observation will not be influenced within this range
World Scene.The size is the diameter dimension of depth of field regulating device (if depth of field regulating device is ellipse, because of institute above
The contrary of oval shape and optical deformation is stated, keeps the shape of depth of field regulating device in visual effect approximate circle, institute
The size stated also approximate circle diameter dimension thus).
The depth of field regulating device can be made of the metal foil material of high reflectance, be such as made of silver foil.
At least two projection arrangements, and the quantity of the depth of field regulating device and institute are fixed on the frame mounting
The quantity for stating projection arrangement matches.The binocular or multi-eye stereo effect of the big depth of field may be implemented.
The image-forming principle of the depth of field regulating device used in the present invention is similar to pinhole camera or apeture lens, generation
Image has the very big depth of field, can be merged well with real world.As shown in Fig. 2, explaining myopia observation object
Generate fuzzy reason.Since the crystalline lens of myopia is thick and focus is in front of retina, the light from object point A is in retina
On be divided into tri- points of A1, A2, A3, can not focus on the retina, therefore the phenomenon for seeing that object is fuzzy can be generated.As shown in figure 3,
It illustrates to see the clearer reason of object after myopia wears pin hole mirror.Since the light from object point A after pin hole mirror by limiting
System relatively narrow regional imaging near retina is A' point, so that the object point observed is more more clear than before wearing pin hole mirror
It is clear.Based on the above principles, enable projection arrangement issue light pass through pin hole mirror up to observer eyes can solve tradition at
As unsharp problem.However, it is exactly diffraction phenomena that pin-hole imaging, which there is a further problem, diffraction makes the light across pin hole
Line diffuses, it is difficult to form clearly image.Principle based on the above pin hole effect is it is found that the image formed on retina is clear
Clear degree and diffraction effect all increase as pin hole becomes smaller, and have certain limitation.In view of the above-mentioned problems, adopting in the present invention
The control to light is realized with depth of field regulating device.As shown in figure 4, when depth of field regulating device is placed on drawing axis, object point A
By the A' of projection on the retina, B' is generated on the retina from the light B that projection arrangement issues at the same time, and heavy with A'
It is folded.In other words, because A' and B' projects same point on the retina simultaneously, can simultaneously clearly observation real world and
Virtual image.
Depth of field regulating device is based on pin hole principle control reflection virtual image in the present invention, and generates the virtual graph of the big depth of field
Picture makes user keep the high-visible of virtual image while paying close attention to real world.It therefore, is realization pin hole effect, the depth of field
The size of regulating device should be less than pupil of human size (6-8mm).Theoretically, the shape of depth of field regulating device should be round, real
It is most appropriate to be designed as elliptical shape in view of factors such as optical distortions for border.The reason is that, depth of field tune easy to carry for user
Regulating device is embedded in eyeglass, and the depth of field regulating device being embedded into lens according to the incidence angle and lens index of light not
It is same to generate deformation.Therefore, the present invention using ellipse design, elliptical shape and optical deformation it is contrary, make
The shape for obtaining depth of field regulating device in visual effect is approximately round.
In conclusion pin hole effect can be generated when the size of depth of field regulating device is less than pupil of human.In order to make user
Virtual image also keeps high-visible while paying close attention to real world, and the suitable size of depth of field regulating device is at 50-700 μm.This
Outside, the virtual image brightness that projection arrangement generates is reduced as the size of depth of field regulating device reduces, and is needed according to virtual graph
The acutance of picture and brightness are suitably set the size of depth of field regulating device.The size phase for the depth of field regulating device chosen in the present invention
To front (being located in eyeglass) that is smaller, and being placed on eyes, it will not affect that user observes real-world scene.
The material of depth of field regulating device is different from general glass lens, can be silver foil (or visible light region have
There is the metal foil of high reflectance).The reason is that, the surface suitable for the depth of field regulating device that the present invention designs is ultra-thin flat song
Face is not only easy to adjust its area and easily be embedded into eyeglass, without additional attachment device.In addition, increasing the depth of field adjusts dress
The area set, the depth of field is reduced while the acutance and brightness of virtual image not only can be improved, and (range that can be focused becomes
It is narrow), realize the Zoom effect similar to concave mirror to convex mirror.
Convenient for user's wearing and fixed projection arrangement and depth of field regulating device, frame mounting can be frame, eye protection
The forms such as cell mount, the helmet or HMD.Frame mounting includes eyeglass, and the material of eyeglass can be transparent or semitransparent.Based on this
The displaying principle of invention, projection arrangement and depth of field regulating device can any way be fixed on frame mounting.In actual production,
Depth of field regulating device is directly placed on drawing axis tool to acquire a certain degree of difficulty.For this purpose, depth of field regulating device is placed in eyeglass
It can effective solution this problem.For example, depth of field regulating device may be mounted on the spectacle lens or transparency cover of the helmet, it is contemplated that
The appearance and rigidity of protectiveness and device to depth of field regulating device, depth of field regulating device are suitable for that can be embedded in eyeglass.Moreover,
The transparency of eyeglass is arbitrarily adjusted according to the demand of user, can be suitable for the virtual visual field of person visually impaired.
