Observation；When without using convertible mixing virtual reality display device, display unit can be rotated around the shaft, to drive display
Unit, lens unit and speculum and associated satellite device rotate to overhead, you can very easily observe the external world, do not have to
By convertible mixing virtual reality display device from the beginning on remove, and very easily speculum can be rotated to around the shaft again make
Angle, it is convenient, fast, greatly improve the usage experience of observer.Especially, when convertible mixing virtual reality is aobvious
When display unit, lens unit and the speculum and associated satellite device of showing device rotate to overhead, display unit, lens list
Member and speculum and associated satellite device and power supply are at the top of the number of people, can make convertible mixing virtual reality display device
In the middle part of the crown, torque becomes smaller center of gravity as far as possible, more balanced to the pressure on head, will be dropped to most to the pressure of the bridge of the nose
It is low so as to wear more comfortable when convertible mixing virtual reality display device.
When head and processing unit articulating device are the gear or ratchet that can be limited, can quickly by
Display unit, lens unit and speculum and associated satellite device rotate to the angle used around the shaft, without being debugged, make
With more convenient.
Lens unit is arranged in central space between display unit and the speculum.
Display screen is oppositely arranged with lens, and the plane where display screen is parallel with the plane where convex lens, and by one
It is an entirety to open there are two the fixed setting of the box body of mouth, and the opening of box body just accommodates two pieces of convex lenses, the top in box body
Be fixedly installed display screen, box body is provided with the one of convex lens down, and speculum is located at the lower section of convex lens, and convex lens with instead
It is opposite to penetrate mirror.Box body is integrally provided on head-wearing device, is located at the upper forepart of the number of people, the upper front of human eye, display screen, convex lens
Mirror, speculum are in integrally to be vertically arranged.The image that display screen is shown projects after convex lens deforms on speculum, then reflects
Enter human eye.Display screen, convex lens and the speculum being vertically arranged make the light path part of script horizontal direction be transferred to vertical side
To saving space.Processing unit is fixed at the display unit on the head-wearing device outer surface.Because of head-wearing device
For rigid mount, so processing unit can flexibly be fixed on the top of head-wearing device, make the stress on head evenly, and
So that the torque of convertible mixing virtual reality display device becomes smaller, become smaller therewith to the pressure on head, the bridge of the nose so that wearing is turned over
It is more comfortable when rotatable mixing virtual reality display device.
In the present embodiment, the two-end-point of the cambered surface cross section of cambered surface speculum is formed by straight line and the horizontal direct projection of human eye
Direction be in 42 ° of angles, the image that display screen is shown projects after convex lens deforms on speculum, then reflects into human eye.
Speculum is located at below convex lens, can be directly fixedly connected by connecting rod or connection sheet outside the box body where convex lens
On wall, to firm light path of the display screen to convex lens to speculum, ensure display effect.
Embodiment three refers to Fig. 1, Fig. 2 and Fig. 3.
A kind of convertible mixing virtual reality display methods comprising following steps：
S1, the position for obtaining observer and azimuth information, the position for obtaining observer and azimuth information；
S2, image data crawl, according to the observer positions obtained step S1 and azimuth information, crawl is obtained with step S1
Observer position and azimuth information it is corresponding indicate virtual three-dimensional space computer graphics data；
S3, image data processing, what is had according to the lens unit includes without the curvature being confined to, focal length, diameter
Parameter carries out reverse distortion processing to image data, then carries out mirror image processing, and then output is by reverse distortion and mirror image processing
Image data.
When handling image data, the point of the normal picture randomly selected and the corresponding points of fault image are first obtained
Cartesian coordinate：The cartesian coordinate is converted into polar coordinates by spherical model：According to the distortion of the radius vector in polar coordinates
Front and back value obtains then reversely being distorted by rate radius to calculate frame out distortion rule for the spherical model, because
It also needs to reflect by speculum, so, after reversed distortion, then mirror image processing, that is, reverse mirror image is carried out, to make display screen display
The image shown, projects after lens distortion on speculum, then it is normal picture to reflect into human eye.
In step s3, image can be interchanged the step of inversely distortion and image mirrors are handled.Image data is carried out
After mirror image processing, what is had further according to the lens unit includes without that the curvature being confined to, focal length, diameter parameters and cambered surface are anti-
The curvature of mirror and the distance parameter of cambered surface speculum and lens unit are penetrated, reverse distortion processing is carried out to image data, it is then defeated
Go out the image data by mirror image processing and reverse distortion processing.
After step S3, image and extraneous image that Overlapping display unit is shown.At this point, what is be imaged in human eye is aobvious
The Overlay of image and extraneous image that display screen is shown, you can generate augmented reality effect to increase on the basis of virtual reality
Fruit shows that equipment can obtain more preferably effect compared to common enhancing
Example IV refers to Fig. 1.
In the present embodiment, lens unit uses two pieces of planoconvex lens, two pieces of planoconvex lens to correspond to the right and left eyes of people respectively.Reflection
The mirror back side of mirror is in 25 ° of angles with the direction of the horizontal direct projection of human eye, and the light that display screen is sent out projects after planoconvex lens deforms
Onto speculum, then reflect into human eye.When the two-end-point of the cambered surface cross section of cambered surface speculum is formed by straight line and human eye water
When the straight direction penetrated is in 25 ° of angles, the spacing of planoconvex lens and speculum can contract shorter, reduce display screen and arrived to planoconvex lens
The vertical dimension of speculum.
Embodiment five refers to Fig. 1.
In the present embodiment, lens unit uses two pieces of Fresnel Lenses, two pieces of planoconvex lens to correspond to the right and left eyes of people respectively.
The mirror back side of speculum is in 60 ° of angles with the direction of the horizontal direct projection of human eye, and the light that display screen is sent out becomes by Fresnel Lenses
It projects on speculum, then is reflected into human eye after shape.When the mirror back side of speculum and the direction of the horizontal direct projection of human eye are in 60 ° of angles
When, the spacing of Fresnel Lenses and speculum increases, and the vertical dimension of display screen to Fresnel Lenses to speculum increases, but can
More effectively shorten the size of the horizontal direction of entire virtual reality display device, and display screen, Fresnel Lenses and speculum
Center of gravity is more close to the number of people so that the torque of virtual reality display device becomes smaller, and becomes smaller therewith to the pressure on head, the bridge of the nose, carries
Height wears comfort level when virtual reality display device.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as be without departing from technical solution of the present invention content, it is right according to the technical essence of the invention
