Description
Technical field：
The present invention relates to a kind of VR Helmet Mounted Displays, more particularly, it is related to a kind of visual angle broadening, it is changeable monocular, double
The VR Helmet Mounted Displays of item stereo vision, the display can be used for 2D/3D video display, 360 ° of panoramas, VR game etc..
Background technology：
As the display terminal of virtual reality, VR Helmet Mounted Displays be by image caused by small two-dimension display by
Optical system is amplified, and the light that miniscope is launched makes image produce similar distant place effect, profit because of refraction by convex lens
Near objects are amplified to this effect and views and admires at a distance and reaches so-called panoramic vision.VR Helmet Mounted Display abbreviation VR heads show,
Mainly point three classes：VR glasses, the VR helmets and VR all-in-ones.
VR glasses, it is the headset equipment (Mobile VR) of the mobile phone with glasses box, representational equipment has
Google Cardboard, Gear VR and storm wind witch mirror, although it is good to experience no VR helmets, because its cost is cheap, portable
Formula and convenient operation, with the fast lifting of smart mobile phone performance, turning into what the VR helmets were being shown under current technical conditions
Main flow.
The VR helmets, it is necessary to which connect computer immerses headset equipment (HMD), and its representative is exactly Oculus Rift, Sony's
PlayStation VR, and HTC/Valve VIVE), the VR helmets it is leading at this stage be Game Market.
VR all-in-ones, its design have taken into account light and performance, have allowed user to break away from the constraint of external equipment, built-in processing
Device, internal memory, display screen can meet the needs of most game and video are to hardware, and cost is higher.
It is well known that the primary factor for determining VR effects is exactly the display performance of equipment.Existing VR heads show, either intelligence
The single screen of energy mobile phone separates, or the double screen structure of VR all-in-ones, and simple eye corresponding viewing area width is usually no more than 70mm,
Obtaining the broad visual field needs bigger optical magnification, causes pixel lattice high-visible, and common thinking is to use
4K the or even 8K screens of more high definition eliminate pixel lattice, but superelevation cls improving display frame frequency and meeting image transmitting bandwidth,
And bring new pressure again in terms of hardware cost.Using existing software and hardware resources, display frame frequency and transmission belt are being kept
It is wide it is constant under conditions of, do not increase added burden to improve image definition, pixel lattice phenomenon is mitigated or eliminated be the present invention
The first purpose.
No matter video display, image, or VR pan-shots, 2D contents are far more than 3D contents, and the current VR helmets are shown
Device is also inhibited the third dimension of itself by VR Binocular displays without this concept of single eye stereo vision, panoramic video.Mesh of the present invention
Two be to apply single eye stereo vision in VR heads are aobvious, lift the third dimension and feeling of immersion of 2D contents.
Existing VR heads, which show, is showing 2D/3D films and during video, the display height of single screen image be screen two/
One, i.e. 3840*2160 4K video frequency programs, monocular display resolution is 1920*1080 on 4K screen smart mobile phones, and display is differentiated
Rate, VR visual fields are not effectively utilized.The three of the object of the invention be using visual angle broadening technology improve display resolution,
Expand and show visual field.
The content of the invention：
The invention discloses a kind of principle and method of the changeable VR Helmet Mounted Displays of the monocular binocular of visual angle broadening.Purpose
It is resolution ratio and the available field of view for by image broadening, making full use of display screen, improves the definition that 2D/3D is shown, expands
Big display visual field；The monocular stereoscopic display of 2D videos is realized by the switching of monocular binocular, improves VR third dimension and feeling of immersion.
The aobvious structure of existing VR heads is as shown in figure 1, the right screen image projection of left screen that VR heads show is amplified to by a pair of eyepieces (5)
At a distance.It is too many no more than interpupillary distance to be limited to viewing area width, can only rely on and improve eyepiece enlargement ratio to obtain big visual field, this
3 points of deficiencies can be brought：
A. pixel lattice is fairly obvious；
B. it is not consistent with the oval wide visual field of human eye by the circular visual field obtained after the shade of the visual field；
When c. playing movie and video programs, the utilization rate of viewing area is less than 50%, therefore video display regional vision is not broad enough, clearly
Clear degree is not high enough.
VR heads disclosed by the invention show structure as shown in Fig. 2 being kept off by display screen, broadening mirror, light path switch, eyepiece, separation
Plate forms.Display screen can be double screen or single screen or so multi-section display；Light path switch is preferentially fast using liquid crystal light valve
Door, can also use mechanical shutter.
It is to by left and right screen image broadening, be obtained under conditions of display all over the screen to increase broadening mirror between eyepiece and screen
Obtain wide field-of-view image.For the purposes of reaching 110 ° of horizontal field of view, after increasing broadening mirror, the magnifying power of eyepiece can be reduced to original
50~60% come, pixel lattice is substantially improved, and the oval visual field obtained under the shade of the visual field more meets human eye and regarded
Open country, definition is high when watching movie and video programs, and the visual field is bigger.The position of broadening mirror (3) is between display screen and eyepiece (5), broadening
Mirror (3) and eyepiece (5) front and rear can be adjusted, and broadening mirror weakens close to screen, broadening effect, and broadening mirror is clear close to eyepiece, image
Clear degree reduces, it is therefore desirable to adjusts broadening mirror to suitable position and is fixed up.Eyepiece, broadening microscope group into amplification light path
Optical axis (8) can left and right adjusting, allow eyes to see more comfortable.
Broadening mirror (3) refers to a kind of lens, and it is that laterally one-dimensional broadening, longitudinal direction are constant by image that it, which is acted on,.As shown in Figure 3
Cylindrical lens be most typical broadening mirror, can also be into a line by parallel light focusing not only with one-dimensional broadening function.
The sectional views of cylindrical lens (10) as shown in figure 4, be that the planoconvex cylindrical lens that a part is formed are intercepted on the area of a circle, when
Focal length F is smaller, and when H is larger, thickness is excessive, and this is the disadvantage of cylindrical lens.Cylindrical lens (10) are to whole figure
As the ratio of broadening is consistent, it is therefore desirable to by shown in original image (19) transverse compression into Fig. 8 to be shown and face of cylinder
Compression image (20) is shown again corresponding to lens, and normal rates image is reduced into by broadening.
Elliptic cylinder lens (11) are second of broadening mirrors provided by the invention, are not possessed parallel light focusing is into a line
Function, but with the preferable broadening effect required for us.The sectional view of elliptic cylinder lens (11) is as shown in figure 5, be
The planoconvex elliptic cylinder lens that a part is formed are intercepted on ellipse area, are gradually reduced equivalent to focal length F from centre to both sides,
Image gradually increases from centre to the ratio of both sides broadening, i.e., high both sides are low among image resolution ratio, meet resolution of eye from
Medium field-of-view is gradually lowered to rule to the both sides visual field, in addition, the visual field of light path is amplified in the amplification being made up of broadening mirror and eyepiece
The definition at edge is also relatively low, that is to say, that elliptic cylinder lens (11) also retains middle graph while the broadening visual field
The fine definition of picture.Need original image (19) horizontal control with changed scale to be shown being compressed into as shown in Figure 8 saturating with elliptic cylinder
Compression image (21) is shown again corresponding to mirror, and normal rates image is reduced into by broadening.
Compound cylindrical lens is the third broadening mirror provided by the invention, the section of compound cylindrical lens as shown in fig. 6, by
Right semi-circle cylindrical lens (12), left semicircle cylindrical lens (13) and the plano lens (14) of centre are combined.With the compound of size
Cylindrical lens is smaller than cylindrical lens thickness, and middle plano lens does not have broadening effect, the semi-cylindrical lens on both sides to image
With the left and right edges part of larger ratio broadening image, i.e., high both sides are low among image resolution ratio, while the broadening visual field
Remain the definition of intermediate image.Need original image (19) both sides transverse compression to be shown into as shown in Figure 8 with answering
Close the corresponding compression image (22) of cylindrical lens to show again, normal rates image is reduced into by broadening.
The major parameter of broadening mirror (3) includes length L, height H, focal length F, in addition to cylindrical lens (10), broadening mirror
Focal length F is parameter, and without focussing force, L, H are less than 70mm under normal circumstances, and the distance that eyepiece (5) arrives display screen is also little
In 70mm.Ratio by original image transverse compression is related to the structure of broadening mirror and focal length, can calculate or pass through experiment
Measure.It is combined in addition, two panels planoconvex broadening mirror (3) is put down to smooth, still can forms the broadening of our needs
Mirror.
Three kinds of broadening mirrors disclosed by the invention can mitigate weight by Fresnelization.As shown in fig. 7, only with the face of cylinder
Illustrate the light-weighted process of broadening mirror (3) Fresnel exemplified by lens：Cylindrical lens (10) play refraction action to light
The superficial layer of gas contact, we split the face of cylinder in the straight line of camber Fresnel post lens refracting layer (16) and cylindrical lens
Transmissive portion (15), line transmission part is removed, and straight Fresnel post lens refracting layer (17) is obtained after remainder processing,
Directional light can be pooled to a focal line (18).
The amplification light path of broadening mirror and eyepiece composition has the characteristics of non-paraxial photoimaging, visual field is wide, display image quilt
Horizontal broadening, after eyepiece amplifies, there is larger pincushion distortion, it is necessary to be compensated again to the image after transverse compression,
It is set just to be reduced into standard picture after amplifying.
In addition to binocular stereo vision, the present invention by single eye stereo vision be also applied to vision broadening VR heads it is aobvious in.
VR shows that 2D/3D has three kinds of modes：
A. eyes see 3D rendering, have binocular parallax, third dimension is strongly；
B. eyes see 2D images, due in the absence of binocular parallax, enhancing the flatness of display in itself, weakening image
Third dimension, particularly close shot and feature, shifted onto by force at a distance, occurred " giant's phenomenon ", lose sense within reach
Feel；
C. it is simple eye to see 2D images, when particularly seeing 2D video display, 2D panoramic videos, due to the presence of motion parallax, have non-
Often good third dimension and feeling of immersion.
First two mode need not switch, and be the aobvious display methods used of current VR heads, and the present invention switches monocular binocular
Be applied to VR heads it is aobvious in, realize the monocular stereoscopic display of 2D images.The switching of monocular binocular can use two methods of software and hardware
Realize.
Software chang-over method is to set handoff functionality to realize in VR plays APP：
A. when broadcasting content is 3D rendering and video, 3D rendering on the double screen of left and right to showing simultaneously；
B. when broadcasting content is 2D images and video, 2D images are shown simultaneously on the double screen of left and right；
C. when broadcasting content is 2D videos, alternately single screen shows that not shown screen is arranged to black on the screen of left and right,
As shown in Figure 9；
D. when broadcasting content is 2D videos, one in closing left and right screen, single screen is shown.
It is only to need the installation APP on VR heads are aobvious to can be achieved with the switching of monocular Binocular displays using the advantages of software exchange,
Simple and easy, pent screen black background does not reach black when being disadvantageous in that monocular display, our eyes
In it is seen that grey, the 2D images seen with another eyes exist in brains slight harasses.
Hardware exchange method is that shutter is set in two groups of the left and right light path that VR heads show, and shutter can see correspondingly when opening
Screen picture, corresponding screen picture is can't see during shutter close, realizes that monocular Binocular displays switch by the break-make of shutter.
Shutter can be using mechanically or electrically minor structure, the position of shutter can be arranged on any position of light path, it is contemplated that what VR heads showed
Design feature, we use liquid crystal light valve shutter (6,7), shutter are positioned close into eyepiece (5) place, as shown in Fig. 2 can subtract
Light eyes are harassed.Liquid crystal light valve shutter can also be used cooperatively with software chang-over method, the control of liquid crystal light valve shutter (6,7)
Signal and voltage can be shown by VR heads or the USB port of smart mobile phone provides.
Identical with software chang-over method, hardware exchange can also realize above-mentioned 4 kinds of displays, it is apparent that the third left and right is alternate
Monocular stereo display method is recommendable, sets suitable alt time T, and monocular, which is shown, brings third dimension and feeling of immersion
Highly significant is lifted, caused visual fatigue is smaller.The purpose that alternately monocular is shown is to be regarded to releive caused by simple eye viewing
Fatigue, therefore make periodically alternately to be not required in that, in playing process, alt time T can change, as long as meeting：
Do not cause and alternately flash, monocular stereo vision can be achieved, simple eye visual fatigue can be mitigated.Experiment shows that T was at 2~30 seconds
Scope is appropriate, and alt time can be adjusted according to the degree of fatigue of right and left eyes, will can also more show that the time distributes
Give eyesight preferable dominant eye.
