Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. It should be noted that, the terms "upper", "lower", "left", "right", and the like in the embodiments of the present invention are described in terms of the angles shown in the drawings, and should not be construed as limiting the embodiments of the present invention. In addition, in the context, it will also be understood that when an element is referred to as being formed "on" or "under" another element, it can be directly formed "on" or "under" the other element or be indirectly formed "on" or "under" the other element through intervening elements. The terms "first," "second," and the like, are used for descriptive purposes only and not for any order, quantity, or importance, but rather are used to distinguish between different components. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Fig. 1 is a schematic structural diagram of an eye tracking device in the prior art. Referring to fig. 1, the eye tracking apparatus performs direct photographing by a camera 1 under the human eye while performing mapping of illumination light supplement and purkinje using a detection light source 2 of infrared rays.
Among them, the widely used method of eye tracking technology is called "pupil-cornea reflex method" (the pupil center cornea reflection technique), which uses the feature of keeping unchanged during eye movement, and is Purkinje image (Purkinje image) on the outer surface of the cornea of the eyeball, which is a bright spot on the cornea of the eyeball, and is generated by the reflection of light entering the pupil on the outer surface of the cornea.
Because the camera 1 is fixed in position, the screen (the detection light source 2) is fixed in position, the center of the eyeball is unchanged (assuming that the eyeball is spherical and the head is motionless), the absolute position of the purkinje is not changed with the rotation of the eyeball (in fact, the small-amplitude movement of the head can also be calculated by cornea reflection). But its position relative to the pupil and eye ball is constantly changing-for example, when the user stares at the camera, the purkinje spot is between the user's pupils; and when the user lifts his head, the purkinje spot is just below the user's pupil. Thus, the pupil and purkinje positions on the eye image are positioned in real time, and the cornea reflection vector is calculated, so that the line of sight direction of the user can be estimated by using the geometric model. Based on the relationship between the user's eye characteristics and the screen presentation content established in the pre-calibration process (i.e., letting the user look at a specific point on the screen), the instrument can determine what the user is looking at on the screen.
However, the direct photographing method in fig. 1 results in a large size of the device, which cannot be applied to the miniaturization requirement of the display device. In order to increase the working distance of the camera, there is a variant scheme in the prior art, in which the image acquisition of the eyes needs to be performed within a certain angle range under the eyes, and the working distance of the camera is slightly increased by rotating the angle of the camera, but the effect is general, and the problem that the acquisition distance of the camera is limited is not basically solved.
In another prior art scheme, a camera is used for reflection, and fig. 2 is a schematic structural diagram of another delay tracking device in the prior art. Referring to fig. 2, in order to increase the working distance of the camera 1 based on the conventional direct photographing scheme, a plate 3 that can transmit visible light while reflecting infrared light needs to be added, at this time, the optical path of the camera reflects on the surface of the plate 3 when passing through the plate 3, and at this time, the optical path can be greatly increased. But the volume, weight and cost are increased correspondingly due to the need to add an additional reflective plate.
In view of the above, an embodiment of the present invention provides an eye tracking device. Fig. 3 is a schematic structural diagram of an eye tracking device according to an embodiment of the present invention.

In the embodiment, for example, in order to improve the definition of the infrared spots in the eyeball image, and for protecting the eyeball of the user, infrared light with a wavelength between 850nm and 940nm is generally used. The detection light source 10 may comprise at least one infrared lamp, such as an infrared light emitting diode. For example, the detection light source 10 may include an annular lamp panel, on which a peripheral infrared lamp (not shown in fig. 3) is disposed for providing light required for imaging the human eye. The camera 30 is configured to receive light to image the human eye 20, and the specific structure of the camera 30 is not limited in the embodiment of the present invention, and may be selected according to practical situations.
In this embodiment, the type of the reflecting device is not limited, alternatively, the reflecting device 40 includes a reflecting mirror, a prism or an infrared cut-off filter, and other devices that reflect infrared light may be selected to replace the reflecting device, and when implementing, the reflecting surfaces of the reflecting mirror and the prism may be further coated with a reflection enhancing film, and when implementing, the reflecting device may be designed according to practical situations. Compared with the prior art adopting direct shooting, the refraction of the optical axis angle of the reflection optical path of the human eye 20 realized in the embodiment improves the space utilization rate of the eye visual axis direction, and reduces the image acquisition angle (optical axis angle), so that the image acquisition can be carried out in the range of the virtual reality display equipment and the augmented reality display equipment which are closer to the human eyes.
According to the technical scheme, the reflecting device is arranged on the reflecting light path of the human eye, so that the optical axis of the reflecting light path of the human eye is not perpendicular to the imaging surface of the camera, the thickness of the system in the direction parallel to the visual axis is reduced, eyeball tracking is carried out at a shorter working distance, and the size of equipment is reduced.

In this embodiment, the reflecting device 40 is disposed inside the imaging lens 31, so as to realize the refraction of the optical path inside the imaging lens 31, the specific refraction angle can be designed according to practical situations, the imaging surface of the photosensitive element 32 after reflection is no longer parallel to the surface of the first lens group 311, and the thickness of the system in the direction parallel to the viewing axis can be reduced.

By way of example, fig. 5 shows that the first lens group 311 includes two lenses, and the second lens group 312 includes one lens, wherein the dotted line represents the optical axis of the lens group, and the shape, number, and type of the lenses may be designed according to practical requirements.
Optionally, the imaging lens comprises a poloxamer lens or a periscope lens.
It is understood that a Mooney lens refers to a lens designed to satisfy Mooney's law, the law of the Moire's law is that when the extension surfaces of the three surfaces of the object plane, the image plane and the lens plane are intersected in a straight line, a comprehensive and clear image can be obtained, and the imaging quality can be improved by utilizing the Moire's lens. The imaging lens may also adopt a periscope lens, for example, the structure shown in fig. 5, the specific angle of the deflected optical axis is not limited to 90 °, any other angle can be designed according to the actual structure, the positions of the specific imaging lens and the photosensitive element are not under the human eyes, and the imaging lens and the photosensitive element can be designed according to the actual requirement, and the embodiment of the invention is not limited.
In some embodiments, the imaging lens may be a complete module, and the optical path in the lens cannot be folded, and in other embodiments, the optical path may be folded, that is, the reflecting device is disposed outside the imaging lens. Fig. 6 is a schematic structural diagram of an eye tracking device according to another embodiment of the present invention. Referring to fig. 6, optionally, a camera 30 includes an imaging lens 31 and a photosensitive element 32; the reflecting device 40 is disposed at a side of the imaging lens 31 away from the photosensitive element 32, and light reflected by the human eye 20 is reflected by the reflecting device 40 and transmitted by the imaging lens 32, and then is incident on the photosensitive element 32.

Referring to fig. 7, optionally, a camera 30 includes an imaging lens 31 and a photosensitive element 32; the reflecting device 40 is disposed on the optical path between the imaging lens 31 and the photosensitive element 32, and the light reflected by the human eye 20 is sequentially transmitted through the imaging lens 31 and reflected by the reflecting device 40 and then enters the photosensitive element 32.
The same technical effect can be achieved by disposing the reflecting device 40 before or after the imaging lens 31.
Optionally, the eyeball tracking device is further used for realizing iris recognition according to the eyeball image.
It is understood that the iris is an annular portion between the black pupil and the white sclera that contains many interlaced spots, filaments, crowns, fringes, crypts, etc. of detail. And the iris will remain unchanged throughout the life cycle after the fetal development stage has formed. These features determine the uniqueness of the iris features and also the uniqueness of the identification. Thus, the iris feature of the eye can be regarded as the identification object of each person. In this embodiment, the identity recognition function of the user can also be realized by using the eyeball image shot by the camera.
In particular, in order to avoid formation of infrared spots in the iris region during recognition, an infrared lamp which does not directly irradiate the eyeball of the user may be disposed in the detection light source, and the wavelength of the infrared lamp may be between 760nm and 850nm, where the fact that the infrared lamp does not directly irradiate the eyeball of the user means that the infrared lamp does not directly irradiate the human eye when reaching the effective working brightness, but irradiates other places, such as the eyelid of the user, irradiates the human eye through diffuse reflection, and then images on the infrared camera, the infrared camera obtains an eyeball image of the user, and the iris region on the eyeball image has no infrared spots.
