Description

The method for correcting image of head-mounted display apparatus and system

Technical field

The present embodiments relate to technical field of image processing, particularly relate to a kind of head-mounted display apparatus Method for correcting image and system.

Background technology

Head-mounted display apparatus is generally filled by display device (display floater or micro-projection arrangement) and optics Put composition, by Optical devices, image source is amplified, reach shown object actual size the biggest The imaging effect of size, gives, in conjunction with audio system, the telepresenc that wearer is good.As virtual reality Important component part in (Virtual Reality, VR) system, military training, technical training, The fields such as consumer entertainment also exist extensively application.

Along with the continuous upgrading of handset processes ability and display screen, there is a kind of Simple head-worn formula and show and set Standby, only include Optical devices and structure member, there is no independent display device and picture processing chip, Mobile phone is put into wherein, complete display and process function.

Owing to the wearing mode of head-mounted display apparatus determines that it is being perpendicular to the horizontal direction chi of head Very little can not be excessive, otherwise can make the wearable device at equipment centroidal distance head too far, cause having Effect is decomposed stress and is made weight concentrate too much on face, causes the strongest constriction, it is difficult to wear for a long time Wear.Simultaneously as the reason of human eye physiological make-up, the near point of vision (can focus on and make observing object Body forms the proximal most position of blur-free imaging at retina) need beyond 10cm, and the near point of vision Vary with each individual, and increase with the age and gradually become remote.So, head-mounted display apparatus uses Two independent Optical devices show image to images of left and right eyes respectively, and the structure of head-mounted display apparatus is shown Being intended to as it is shown in figure 1, wherein, each Optical devices can include independent lens, and display device is (aobvious Display screen) it is that images of left and right eyes shows two width images according to centrage.

In order to make different wearers all be obtained in that imaging clearly, need to make Optical devices and wear The binocular vision situation of person and interior interpupillary distance (In Pupil Distance, IPD) match.Wear-type shows Show that the regulation of equipment mainly has two aspects: one, by instrumentality away from changing left and right Optical devices pair Image light source aggregation extent, to mate the diopter of wearer's eyes.Two, by changing left and right light Learn the spacing of device, make wearer images of left and right eyes pupil center be positioned on primary optical axis.

One, diopter regulation:

At present, main employing images of left and right eyes adjusted in concert and independent regulation two ways.Adjusted in concert is i.e. Change the left and right Optical devices (lens) distance to display device simultaneously, generally more serious with myopia Eyes be as the criterion, another eyes then rely on physiological structure oneself regulate ciliary muscle, change crystalline lens bend Luminosity accomplishes self adaptation.But the regulating power of human eye is very limited, being generally up to about the rectification number of degrees is About 200 degree, when the vision difference of images of left and right eyes exceedes adjustable extent, will cause the eyes cannot Observe simultaneously and obtain blur-free imaging.And in order to adapt to unmatched Optical devices, will make the human eye cannot Being maintained at natural state, long-time use is easily caused fatigue, in some instances it may even be possible to deteriorated vision.Independent Regulation uses the adjusting means entirely without association, so that images of left and right eyes can be regarded by Optical devices Power situation reaches accurately to mate, it is to avoid problem present in above-mentioned adjusted in concert.

Above two changes the regulative mode of image light source degree of divergence after Optical devices, it is possible to Make light after the crystalline lens through wearer's difference vision condition, can obtain clearly at retina Imaging.But the size projecting the picture on retina is not the most the most identical.When binocular vision feelings When condition difference is the biggest, the difference of imaging can exceed the distinguishable degree of human eye, causes the stereopsis vision system of people System cannot well synthesize the image that images of left and right eyes obtains, and wearer cannot see very picture rich in detail. In this case may result in the physiological reaction that vision is relevant, for a long time may deteriorated vision.

Two, interpupillary distance regulation:

At present, interpupillary distance regulation is divided into picture position regulation, lenticular spacing regulation two ways.Figure image position Put regulation and can make picture centre and pupil position coupling, but due to pupil position not at primary optical axis On, for range image vertical center line remote position, can be because optical distortion degree difference causes Imaging is unintelligible.Lenticular spacing regulation can make pupil position and primary optical axis coupling, but due in image The heart leaves primary optical axis, also results in the unsharp problem of imaging.

Summary of the invention

The embodiment of the present invention provides method for correcting image and the system of a kind of head-mounted display apparatus, in order to solve Certainly diopter of the prior art regulation and interpupillary distance regulation can cause imaging unintelligible, even deteriorated vision Problem.

The embodiment of the present invention provides the method for correcting image of a kind of head-mounted display apparatus, and described wear-type shows Show that equipment includes displacement measuring device, processor, left and right Optical devices and display device, described method Including:

The described left and right Optical devices length apart from described display device is obtained by institute's displacement measurement device Degree, and, described left and right Optical devices with the relative displacement in described display device parallel direction;

According to described length and described relative displacement, use described processor to images of left and right eyes original graph image source It is corrected, to make revised images of left and right eyes original graph image source imaging on images of left and right eyes retina identical, And make the center of revised images of left and right eyes original graph image source respectively with the center of described left and right Optical devices Alignment.

The embodiment of the present invention additionally provides the image correction system of a kind of head-mounted display apparatus, described in wear Formula display device includes displacement measuring device, processor, left and right Optical devices and display device, described System includes:

Length information acquisition module, fills for obtaining described left and right optics by institute's displacement measurement device Put the length apart from described display device, and, described left and right Optical devices with described display device Relative displacement in parallel direction;
