Description
Technical field：
The present invention relates to a kind of VR Helmet Mounted Displays, more particularly, are related to a kind of changeable monocular, binocular tri-dimensional
The Virtual Reality Helmet Mounted Display of feel, the display as display terminal can be used for 2D/3D video display, 360 ° it is complete
Scape, 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 because refraction produces similar distant place effect by convex lens,
Near objects are amplified to using this effect and views and admires at a distance and reaches so-called panoramic vision.VR Helmet Mounted Display abbreviations VR
Head is aobvious, 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 low
Honest and clean, portable and convenient operation, with the fast lifting of smart mobile phone performance, is turning under current technical conditions
The main flow that the VR helmets are shown.
The VR helmets, it is necessary to which connect computer immerses headset equipment (HMD), and its representative is exactly Oculus Rift, Sony
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 place
Reason device, internal memory, display screen can meet the needs of most game and video are to hardware, and cost is higher.
Shown using the VR heads of Binocular displays, its display content includes 2D/3D films, 360 ° of panoramic videos, roaming,
Picture, VR game etc., these contents can be divided into 2D and the major classes of 3D two.Binocular displays 3D rendering, due to binocular
Parallax, third dimension is strongly；Binocular displays 2D images, due in the absence of binocular parallax, weakening image in itself
Third dimension.No matter video display, image, or VR pan-shots, 2D contents are and current far more than 3D contents
VR Helmet Mounted Displays do not have this concept of single eye stereo vision, even panoramic video also inhibits part by Binocular displays
Telepresenc, this viewing for the 2D movie and television contents of magnanimity is very unfavorable.The present invention is by single eye stereo vision application
In VR heads are aobvious, third dimension and feeling of immersion that lifting 2D contents are shown.
The content of the invention：
The invention discloses the principle and method of a kind of changeable VR Helmet Mounted Displays of monocular binocular, it is therefore intended that by aobvious
Show switching, the 3D videos and image of high-resolution can be not only played with binocular, can also be by way of single eye stereo vision
2D video display and panoramic video are played, improves third dimension and feeling of immersion.
In order to illustrate single eye stereo vision can improve 2D movie and television contents third dimension and feeling of immersion, it is necessary to simply illustrate three-dimensional
The mechanism and foundation of vision.
Human stereo vision can be divided into binocular stereo vision and single eye stereo vision.Because spacing be present in two eyes of people,
Average value is 6.5cm, and for same scenery, the relative positions of right and left eyes is different, this generates binocular parallax,
That is right and left eyes form binocular stereo vision it is seen that discrepant image, is merged in the brain, and binocular parallax is not
Whole foundations that stereoscopic vision is formed, but be most strong in various factors；Motion parallax is by observer and scenery hair
Caused by raw relative motion, this motion makes the size of scenery and position be changed in the projection of retina, makes production
Raw depth perception, can form single eye stereo vision, stereo perception caused by motion parallax is weaker than binocular parallax；Human eye is
Fine-tune to focus on by crystalline lens, the change of focal length allows us to see far and near different scenery, focuses on
Functioned both in binocular stereo vision and single eye stereo vision are formed, stereo perception caused by focusing is weaker than binocular parallax
And motion parallax.
The objective factors such as linear perspective, shadow distribution, air scattering, color, background density, composition, and people
The experience of life is memory of the Stereo Vision of objective object in human brain, can also help people to establish and strengthen three-dimensional
Vision.In addition, completely cut off image boundary using increase visual field in VR is shown and the method in the extraneous visual field, reduction are emphasized
The environmental factor of the plane of delineation, stereoscopic visual effect can also be strengthened.In a word, stereoscopic vision is many factors synthesis
The result of effect.
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 tentacle
Can and sensation；
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 very
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 contents.The switching of monocular binocular can use two kinds of software and hardware
Method is realized.
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, such as on the screen of left and right
Shown in Fig. 1；
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, letter using the advantages of software exchange
Single easy, pent screen black background does not reach black when being disadvantageous in that monocular display, our eye
It is seen that grey, the 2D images seen with another eyes are harassed in brains in the presence of slight in eyeball.
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, monocular Binocular displays are realized by the break-make of shutter
Switching.Shutter can be arranged on any position of light path using mechanically or electrically minor structure, the position of shutter, consider
The design feature shown to VR heads, we use liquid crystal light valve shutter, and shutter is positioned close into eyepiece (5) place, such as scheme
Shown in 2.Liquid crystal light valve shutter can also be used cooperatively with software chang-over method, accordingly even when liquid crystal light valve occurs slightly
Light leak, be also not in harass.The control signal and voltage of liquid crystal light valve shutter can be shown by VR heads or smart mobile phone
USB port 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 with immersing
The lifting highly significant of sense, caused visual fatigue are smaller.The purpose that alternately monocular is shown is for simple eye viewing of releiving
Caused visual fatigue, therefore make periodically alternately to be not required in that, in playing process, alt time T can become
Change, as long as meeting：Do not cause and alternately flash, monocular stereo vision can be achieved, simple eye visual fatigue can be mitigated.Examination
Test and show, T is appropriate in the scope of 2~30 seconds, and alt time can be adjusted according to the degree of fatigue of right and left eyes, may be used also
So that more display times are distributed into the preferable dominant eye of eyesight.
