Description
Technical field
The present invention relates to nearly eye display field more particularly to a kind of nearly eye display devices with eyeball tracking function.
Background technique
Currently, the eyeball tracking on the near-eye display of augmented reality (Augmented Reality, abbreviation AR)
System generallys use infrared ray tracing scheme, and infrared light supply or infrared light supply group are placed on the main body frame of equipment, transmitting
Infrared ray simultaneously enters in infrared camera or infrared image sensor after human eye reflects, and is acquired, realizes to eyeball image
Eyeball tracking function.For example ocular imaging sensor is fixed on to the edge or outside of the visible angle of near-eye display, or will
Infrared light supply group is placed on the frame of eyeglass surrounding, and infrared camera is placed in front of eyeball or in front of side.
As noted previously, as carry eyeball tracking device on existing common near-eye display, be by infrared light supply and
Infrared camera exists independently of near-eye display, and in front of near-eye display or in front of side and increases near-eye display people
Equipment volume in front of side or side at the moment so that near-eye display overall weight is unbalanced, it is preceding it is heavy after it is light, be not easy in wearing solid
Fixed problem.
Summary of the invention
Based on the problems of prior art, the object of the present invention is to provide a kind of nearly eyes with eyeball tracking function
Display device reduces the volume in front of nearly eye display device human eye or in front of side under the premise of not influencing eyeball tracking.
The purpose of the present invention is what is be achieved through the following technical solutions:
Embodiment of the present invention provides a kind of nearly eye display device with eyeball tracking function, comprising: micro display screen, red
Outer light source, infrared camera and conduction optical path；The infrared light supply and infrared camera are each provided at the periphery of the micro display screen, are in
The side of user's eyeball；
The infrared light emission end of the infrared light supply and the infrared optical receiving end of the infrared camera are towards the conduction
The infrared light of optical path, the infrared light supply transmitting is conducted described in entrance after user's ocular reflex again by the conduction optical path
Infrared camera.
As seen from the above technical solution provided by the invention, provided in an embodiment of the present invention to have the function of eyeball tracking
Nearly eye display device, it has the advantage that:
By the way that infrared light supply, infrared camera are each provided at micro display screen periphery, and it is in the side of user's eyeball, to pass
Guide path as infrared light supply infrared light reflection user eyeball to infrared camera optical path so that by infrared light supply and infrared
Camera is advantageously integrated inside nearly eye display device, and far from user's eyeball, rather than independently of nearly eye display device and is located at
In front of its front or side, the volume in front of nearly eye display device or in front of side is effectively reduced, so that nearly eye display device is whole
Weight is more balanced, and user's wearing of being more convenient for is more convenient for consolidating in wearing.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment

In figure: 1- micro display screen；2- infrared light supply；3- infrared camera；4- conducts optical path；5- user's eyeball.
Specific embodiment
Below with reference to particular content of the invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts,
Belong to protection scope of the present invention.The content being not described in detail in the embodiment of the present invention belongs to professional and technical personnel in the field
The well known prior art.
As shown in Figure 1, the embodiment of the present invention provides a kind of nearly eye display device with eyeball tracking function, comprising: micro-
Display screen, infrared light supply, infrared camera and conduction optical path；The infrared light supply and infrared camera are each provided at outside the micro display screen
Week, the side in user's eyeball；The infrared light emission end of the infrared light supply and the infrared light-receiving of the infrared camera
End is towards the conduction optical path, and the infrared light of the infrared light supply transmitting is by the conduction optical path by user's ocular reflex
It is conducted again afterwards into the infrared camera.
In above-mentioned nearly eye display device, infrared light supply and infrared camera are respectively at outside the projection eyeglass of the micro display screen
Week.Preferably, infrared light supply and infrared camera are symmetrical arranged centered on the projection eyeglass of micro display screen.
In above-mentioned nearly eye display device, common infrared light supply and infrared is can be used in the infrared light supply and infrared camera
Camera.
In above-mentioned nearly eye display device, conduction optical path is using conduction eyeglass composition.
The present invention has been integrated in nearly eye and has shown by the way that infrared light supply and infrared camera are each provided at micro display screen periphery
In device, and dependent is located in front of the front or side of nearly eye display device, while realizing eye tracking function, effectively
The volume in front of nearly eye display device or in front of side is reduced, so that entire nearly eye sized display, weight are more balanced, is not deposited
In pre-large post-small, preceding heavy rear light problem, more it is fixed easily when so that wearing, the stability of wearing is more preferable.
The embodiment of the present invention is specifically described in further detail below.
Referring to Fig. 1, the nearly eye display device provided in an embodiment of the present invention with eyeball tracking function, by infrared light supply and
Infrared camera is mounted in nearly eye display device, is located at micro display screen periphery attachment, is in the side of user's eyeball (i.e. human eye)
Face, far from user's eyeball, the infrared ray that infrared light supply issues is transferred to user's eyeball by projection eyeglass and conduction eyeglass
On；According to the reversible principle of optical path, the light after infrared ray reflects on user's eyeball can be returned with original optical path, be installed in
The infrared camera of micro display screen periphery captures, to obtain the infrared view of user's eyeball, realizes tracking user's eye
The function of ball.The nearly eye display device, since infrared light supply to be set to the micro display screen periphery of nearly eye display device, cooperation conduction
Optical path realizes the infrared view acquisition of user's eyeball, since infrared light supply and infrared camera are in user's eyeball (i.e.
Human eye) side volume of the nearly eye display device in front of user's eyeball is reduced, so that entirely far from user's eyeball
Nearly eye sized display, weight are more balanced, and there is no pre-large post-small, preceding heavy rear light problems, improve nearly eye display device
Wearing when firm.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
