Description

Simple eye visual field is adaptive to match method of adjustment and device, wear-type visual device
Technical field
The present invention relates to computer fields, match method of adjustment and device, head in particular to a kind of simple eye visual field is adaptive Wear formula visual device.
Background technique
With the rapid development of virtual reality technology (VR), worn with Oculus Rift, Cardboard, Gear VR etc. Formula visual device (HMD), refers mainly to VR glasses, constantly rises for the VR game of carrier, and institute is not before bringing game player Some degrees of verisimilitude have very strong substitution sense so that game player can be immersed in gaming world completely.However, mesh Preceding VR game the biggest problems are that: game player will appear during game experiencing it is uncomfortable, such as: dizzy, nausea, Wherein, a more important reason is two built-in cameras shortages and game in the HMD device worn and VR game The interpupillary distance of player is adapted to well.Not only VR game, when user using HMD device carry out other activity, such as: see When seeing TV programme, film, can also there be the above problem.
The number obtained after being investigated according to the U.S. for sample size crowd is it has been found that everyone interpupillary distance changes from 52 Millimeter is differed to 78 millimeters, wherein the average interpupillary distance of male is 64.7 millimeters, and the average interpupillary distance of women is 62.3 millimeters.Thus As it can be seen that interpupillary distance varies with each individual.
When the interpupillary distance of user is difficult to match with the eyeglass of HMD device, interpupillary distance when common spectacles will be generated and worn It mismatches equally, user will feel that significant discomfort, eye muscle and eyesight are easy to appear fatigue.However, current HMD device passes through The modes such as knob, support the interpupillary distance value of manual adjustment eyeglass, but generally require artificially to differentiate picture corresponding to current interpupillary distance value Whether face effect reaches most preferably, this is not a good solution for ordinary user.In addition to this, if HMD device is that the picture that user's right and left eyes are shown is not inconsistent with user interpupillary distance itself, then equally will also result in the bad experience of user. By taking VR game as an example, when the spacing in the interpupillary distance of game player and game between two built-in cameras mismatches, if game In two built-in cameras spacing be greater than game player interpupillary distance, it will generate a volume rendering visual field being exaggerated, hold Easily cause the visual fatigue of player；Conversely, if the spacing of two built-in cameras is less than the interpupillary distance of game player in game, depending on The three-dimensional sense on boundary will greatly weaken.And the Software Development Kit (SDK) of VR game user's eye pupil is away from mean value at present The spacing of (63.5 millimeters) as two built-in cameras, it is good that such setting does not ensure that all VR game players obtain Game experiencing.
It can be seen that the interpupillary distance matching scheme of current HMD device, shows in equipment optical element (eyeglass) and picture It is all unable to get and solves well in the process.
Currently, usually used interpupillary distance measurement method is cornea optical reflection method, widely used pupil in reality in the related technology Distance meter is to carry out interpupillary distance measurement according to the design principle of cornea optical reflection method, rough measuring principle and steps are as follows:
The first step, by the sighting target illuminated by light source, (i.e. during inspection light, optometry, guidance is detected the icon that personnel watch attentively Or image), utilize the optical system imaging in centrometer；
Centrometer nose volume pad is placed horizontally at the detected positive middle part of personnel's nasion by second step, so that sighting target is imaged on Immediately ahead of the personnel of being detected；
Third step makes being imaged at the particular job distance of detected personnel at the moment of sighting target；
4th step, when be detected personnel binocular fixation sighting target when, the optical axis of left eye and right eye intersects at above-mentioned specific Operating distance at；
5th step, due to a large amount of light of the corneal reflection of human eye, light will be in the left eye and cornea of right eye for the personnel of being detected A reflective spot (virtual image) is respectively formed on surface；
6th step, observer can observe that reading balance spring (is mounted on the machine on the graduated scale of centrometer by eyepiece Tool device) and the two reflective spots, it is overlapped by mobile reading balance spring with reflective spot, so that reading balance spring shelters from corneal reflection Light (i.e. the virtual image), at this time the position of two balance springs just correspond to two corneas position, to realize balance spring, cornea, the virtual image three One line of point；
Detected personnel's left eye and right eye is calculated in 7th step, the scale difference that can read balance spring by two at this time Distance between cornea；
8th step, since the cornea of human eye is among pupil, thus can obtain be detected personnel interpupillary distance.
In addition to this, by measuring distance of the pupil center for being detected the one of eyes of personnel to bridge of the nose middle line, just Available monocular interpupillary distance, monocular interpupillary distance can more accurately reflect the interpupillary distance information of detected personnel；In addition, passing through change The distance for the sighting target imaging mentioned in above-mentioned steps can also obtain the close with interpupillary distance and far with interpupillary distance of detected personnel, lead to In normal situation, it can be closely slightly less than with interpupillary distance and far use interpupillary distance.
Centrometer based on cornea optical reflection method is widely used, although being counted as accurate and convenient and fast interpupillary distance measurement side Method, but the above method need establish can be realized under precondition existing for observer, when interpupillary distance detection not as One special detection, but user using HMD device viewing VR image before pretreatment operation when, cornea optical reflection method will be shown Must be very clumsy, specific defect is:
(1) it needs one to assist the personnel of detection interpupillary distance, and needs to understand basic measurement knowledge；
(2) need to detect the auxiliary tool of interpupillary distance, such as: centrometer or interpupillary distance meter；
(3) if using the auxiliary tools such as interpupillary distance meter or interpupillary distance meter, it is also necessary to the intensity of illumination for ensuring to detect environment is suitable, So as to clearly view the corneal reflection of detected personnel；
These defects are totally unfavorable for one needs using the user of HMD device.In order to avoid measuring pupil Away from the cost spent, the game player of VR game is carried out especially with HMD device, it is more likely that can directly using and obtain Poor VR experience, or even abandon using VR equipment.
In conclusion interpupillary distance detection method general at present very relies on testing staff and auxiliary detection instrument can It realizes, for wishing to experience the user of VR image using HMD device immediately, such mode of operation is difficult to receive.
In addition to the interpupillary distance detection method of above-mentioned introduction, another more common interpupillary distance detection method be eye movement with Track technology.Eye-tracking technology (or visual trace technology) has extraordinary application prospect in terms of VR.Eye-tracking refers to logical It crosses the position of blinkpunkt for measuring eyes or the movement of eyeball opposing headers and realizes to oculomotor tracking.It is set in HMD By using eye-tracking technology, the current direction of visual lines of available usertracking user, to be provided for user suitable in standby The VR image (being different from head tracking technology) matched.
Eye-tracking technology again can be with further division are as follows: based on software and is based on the two different methods of hardware.It is based on The eye-tracking technology of software obtains the image of face or human eye first with video camera, then using in software realization image The positioning and tracking of face and human eye, thus estimate user on the screen watch position attentively, this method is for image procossing Algorithm have higher requirement, and precision is lower；Hardware based eye-tracking technology, generally using the eye that can lock eyes Motion tracking device continuously records sight variation from eye cornea and the infrared ray of pupillary reflex by intake, to reach note The purpose of record analysis eye tracking process, precision are higher.Also, hardware based eye-tracking technology generally requires user and wears The upper special helmet uses head fixing bracket, is very suitable for the usage scenario of VR.
In hardware based eye-tracking technology, the implementation " pupil-corneal reflection vector method " of extensive utilization includes Following processing step:
The first step, the image that eyeball is obtained using fixed eye-tracking device；
Second step, by the light source coaxial with eye-tracking device, obtain bright pupil image；
Third step, by the light source cheap with eye-tracking device, obtain dark pupil image；
4th step, by by bright pupil image and dark pupil image superposition difference, to obtain relatively sharp pupil image；
5th step, the light spot position that cornea transmitting is obtained using fixed eye-tracking device, and obtained in conjunction with pupil position Emit vector to cornea；
6th step emits vector by cornea, estimates the direction of visual lines (angle) of user.
Eye-tracking technology can obtain sight movement and the direction of user, be applied in HMD device, solution is fitted With property problem with: due to game player's sight change required for VR image change, such as: game player head keep not In the case where dynamic, eyeball is moved, then the VR image seen also moves).However, this method still can not solve user The suitability problem of interpupillary distance and HMD device itself not can avoid even if the sight situation of user can be obtained in real time due to pupil yet Away from being difficult to be adapted to caused image distortion, fuzzy in turn result in that user is dizzy, nausea.
For above-mentioned problem, currently no effective solution has been proposed.
