Description

Technical Field

[0001] The present invention relates to iris recognition technology, and more particularly to iris recognition technology for correcting pupil deviation (bias) by the dominant eye.

Background Art

[0002] The dominant eye is the eye that provides a slightly stronger input to the brain and depends more on precise visual tasks such as aiming or focusing on distant objects. Just as most people have a dominant hand, eyes also tend to have a dominant tendency. However, such dominance is generally less noticeable in daily activities. For supplementary explanation, the dominant eye is the eye that the brain prefers for visual processing. When both eyes act together to form one image, it tends to be led.

[0003] Regarding the medical basis for the dominant eye, there is medical evidence for the existence of the dominant eye supported through research in fields such as ophthalmology, neurology, and psychology. The dominance of the eyes is a well-documented phenomenon, and in particular, it is recognized that in tasks that require concentration and accuracy, one eye plays a more important role in visual processing than the other.

[0004] Regarding the neurological basis, the brain processes visual information from both eyes in terms of cerebral hemisphere specialization, but generally one eye sends a stronger signal to the dominant cerebral hemisphere and becomes preferred. Such dominance is linked to the way the brain integrates binocular vision (vision using both eyes together) to create a single image. According to research using neuroimaging techniques such as functional MRI (fMRI) in terms of the asymmetry of the visual cortex, the visual cortex can exhibit asymmetry in the way it processes information from each eye. The dominant eye often has a greater impact on perception due to such cortical preference.

[0005] In iris recognition devices that lack guide bars to block the surrounding environment / background, the dominant / non-dominant eye problem arises. However, even when guide bars are present, such as in goggles that are within approximately 15 cm, the iris image can still be distorted due to the dominant / non-dominant eye problem. Furthermore, if iris recognition is used as a settlement method in financial markets, users with severe dominant eye symptoms may experience problems in terms of iris image quality, and this issue needs to be resolved.

[0006] On the other hand, Korean Registered Patent No. 10-1797948 discloses a "user guidance device and method" that uses a camera to acquire images of the user, illuminates the user's left or right eye and eye area with illumination light, and guides the user by adjusting the camera's focal position based on the user's images. [Overview of the project] [Problems that the invention aims to solve]

[0007] The present invention aims to avoid the phenomenon in which the iris image of the non-dominant eye is distorted due to pupillary deviation (bias) caused by the dominant eye.

[0008] Furthermore, the present invention aims to solve the problem that reflected light (spectral) does not occur at the precise iris recognition position due to pupillary displacement (deviation), and to capture an accurate image of the iris at all angles. [Means for solving the problem]

[0009] An iris recognition device for correcting pupil deviation using a dominant eye, according to one embodiment of the present invention for achieving the above-mentioned objective, comprises: an iris recognition unit that uses a camera module to recognize the user's face, the pupil positions of both eyes, and reflected light (SPECULAR) generated at the iris recognition position, and determines whether the pupil position and the position of the reflected light can be aligned; an indicator control unit that activates an IR-LED indicator for iris recognition to generate the reflected light at the iris recognition position and activates an additional indicator located on the eyeball side where the pupil position and the position of the reflected light were not aligned; and an iris image generation unit that captures iris images of both eyes when all the reflected light is aligned at the pupil positions of both eyes.

[0010] In this case, the iris recognition unit can determine that the pupil position and the position of the reflected light are not aligned if the center position of the reflected light is more than a predetermined distance away from the center position of the pupil.

[0011] In this case, the iris recognition device for correcting pupil deviation by the dominant eye may further include a half-mirror that reflects the user's pupils to guide the pupil positions of both eyes to the iris recognition position.

[0012] In this case, the additional indicator can be positioned within 2 cm of the iris recognition position reflected by the half mirror.

[0013] In this case, the additional indicator may include a visible light LED additional indicator and an IR-LED additional indicator, the visible light LED additional indicator may be positioned at the upper end of the half mirror, and the IR-LED additional indicator may be positioned on the rear surface of the half mirror.

[0014] Furthermore, an embodiment of the dominant eye pupil displacement correction iris recognition method for achieving the above-mentioned objectives includes the steps of: recognizing the user's face and the pupil positions of both eyes using a camera module; activating an IR-LED indicator for iris recognition to generate reflected light (SPECULAR) at the iris recognition position; recognizing the reflected light (SPECULAR) generated at the iris recognition position; determining whether the pupil position and the position of the reflected light can be aligned; activating an additional indicator located on the eyeball side where the pupil position and the position of the reflected light were not aligned if the pupil position and the position of the reflected light were not aligned; and capturing iris images of both eyes when the reflected light is aligned at the pupil positions of both eyes.

[0015] In this case, the determination step can determine that the pupil position and the position of the reflected light were not aligned if the center position of the reflected light deviates by a predetermined distance or more from the center of the pupil position.

[0016] In this case, the recognition step can be performed by using a half-mirror to reflect the user's pupils and guide the pupil positions of both eyes to the iris recognition position.

[0017] In this case, the additional indicator can be positioned within 2 cm of the iris recognition position reflected by the half mirror.

[0018] In this case, the additional indicator may include a visible light LED additional indicator and an IR-LED additional indicator, the visible light LED additional indicator may be positioned at the upper end of the half mirror, and the IR-LED additional indicator may be positioned on the rear surface of the half mirror. [Effects of the Invention]

[0019] This invention can solve the phenomenon in which the iris image of the non-dominant eye is distorted due to pupillary displacement (deviation) caused by the dominant eye.

[0020] In addition, the present invention solves the problem that specular light does not occur at the accurate iris recognition position due to pupil deviation (bias), and can capture accurate images of the iris at all angles.

[0024] The present invention can be modified in various ways and has various embodiments. These embodiments will be illustrated in the drawings and explained in detail.

[0025] However, this should be understood not as an attempt to limit the present invention to any particular embodiment, but rather as including any modifications, components, or substitutions that fall within the spirit and technical scope of the present invention.

[0026] In describing the components of the embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. Such terms are used to distinguish a component from other components, and the terms do not limit the nature, order, or procedure of the component.

[0027] Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as they would be generally understood by a person of ordinary skill in the art to which this invention pertains.

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, independent reference numerals will be used even for the same components in the drawings, in order to facilitate an overall understanding.

[0031] Figure 1 shows a situation in which an iris recognition error occurs due to pupillary displacement of the non-dominant eye relative to the dominant eye, according to one embodiment of the present invention.

[0032] As shown in Figure 1, it can be seen that the process of recognizing the iris in a situation where pupillary displacement of the non-dominant eye occurs is shown by removing the reflected light (Specular) 10 generated by other light from the iris image captured via the iris recognition device 100 according to one embodiment of the present invention, and recognizing the reflected light (Specular) 20 generated by the IR-LED used in the iris recognition device 100.

[0033] At this time, it can be seen that the IR-LED used in the iris recognition device 100 is located in the center of the iris and that reflected light (Specular) 20 is generated.

[0034] However, if the right eye is the dominant eye, it can be seen that the left eye, which is the non-dominant eye, rotates towards the right eye, preventing the reflected light 30 from being positioned at the center of the iris in the left eye, and thus preventing the capture of a complete iris image of the left eye.

[0035] Conversely, if the left eye is the dominant eye, the non-dominant right eye may rotate towards the left eye.

[0036] Therefore, changes in the position of the eyeballs can prevent accurate acquisition of biological information from both eyes, potentially leading to problems such as the inability to recognize the iris.

[0037] Figure 2 shows a goggle-type iris recognition device according to one embodiment of the present invention.

[0038] As shown in Figure 2, it can be seen that a goggle-type iris recognition device according to one embodiment of the present invention is shown.

[0039] The iris recognition device 100, which corrects pupillary deviation using the dominant eye, can be applied to general portable or standalone devices that do not have a guide device, even if they are not in goggle form.

[0040] The iris recognition device 100 for correcting pupil deviation by the dominant eye may include a half mirror 110, an IR-LED indicator for iris recognition 120, a camera module 130, additional indicators 131 and 132, and an eyeball position guidance unit 140.

[0041] The Half Mirror 110 displays an image of the user's pupils reflected in the mirror, while allowing infrared (IR) images to pass through.

[0042] The half-mirror 110 can guide the user to accurately align with the iris recognition position while confirming the pupil's reflection in the image.

[0043] The user can align their eyes with the predetermined iris recognition position of the iris recognition device 100 while viewing their own pupils reflected in the half-mirror 110. Through this, the user's gaze can be guided to the precise iris recognition position for iris recognition.

[0044] The Half Mirror 110 can collect iris information through an image transmitted via an IR-LED or camera.

[0045] The IR-LED indicator 120 for iris recognition can provide the infrared (IR) light source necessary for iris recognition.

[0046] At this time, the IR-LED indicator 120 for iris recognition directs infrared light to the center of the user's pupil, and when the reflected light (specular) is reflected back to the iris recognition position, which is the center of the camera module 130's shooting, it creates ideal conditions for the pupil displacement correction iris recognition device 100 for the dominant eye to capture an iris image at the correct iris recognition position.

[0047] The iris recognition device 100 can accurately obtain the data necessary for iris recognition by reflecting light from an IR-LED located at the center of the pupil, thereby providing highly reliable iris recognition.

[0048] At this time, the iris recognition IR-LED indicator 120 can turn the iris recognition IR-LED on and off and check the presence or absence of reflected light (specular) from the iris recognition IR-LED in the pupil using a difference image. The technology for recognizing the pupil and iris is not included in the scope of the present invention, and prior art can be used.

[0049] The camera module 130 can capture iris images.

[0050] The additional indicators 131 and 132 can be positioned within 2 cm above the iris recognition position reflected by the half mirror 110.

[0051] In this case, the additional indicator 131 is a visible light LED indicator.

[0052] In this case, the additional indicator 132 is an IR-LED indicator.

[0053] An IR-LED additional indicator 132 may be used on the rear of the half mirror 110. If a visible light LED additional indicator 131 were to be mounted on the rear of the half mirror, the user would not be able to see the visible light LED additional indicator 131.

[0054] The additional indicators 131 and 132 can recognize the dominant eye and activate the additional indicator on the non-dominant eye side, guiding the pupil center of the non-dominant eye to be positioned at the center of the camera module 130's imaging.

[0055] The visible light LED additional indicator 131 can be positioned at the "upper end" of the half mirror 110.

[0056] The additional IR-LED indicator 132 can be positioned on the "rear" side of the half mirror 110.

[0057] The additional IR-LED indicator 132 can be positioned within 2 cm of the iris recognition position reflected by the half mirror 110, which is captured by the camera module 130. For example, the additional IR-LED indicator 132 can be positioned within 2 cm of the "upper edge" of the iris recognition position reflected by the half mirror 110.

[0058] If this range is exceeded, the user's iris may produce specular reflections from the IR-LED indicator 132, obscuring the iris's biometric information.

[0059] The eyeball position guidance unit 140 can indicate the area and position where the user should align their eyes.

[0060] Figure 3 shows the dominant eye correction process according to one embodiment of the present invention.

[0061] As shown in Figure 3, the dominant eye pupil displacement correction iris recognition device 100 according to one embodiment of the present invention can guide the user to naturally focus their gaze on the right eye when the right eye is the dominant eye. As a result, the pupil of the left eye rotates toward the right eye, which can lead to a problem where the entire iris of the left eye cannot be accurately captured by the camera in the dominant eye pupil displacement correction iris recognition device 100 (41). Consequently, there is a risk that the left eye iris information will be incompletely collected, increasing the likelihood of errors occurring in the iris recognition process.

[0062] For example, if a right-eye dominant user aligns their gaze in front of the device, the pupil 41 of the left eye rotates to the right, and only a portion of the iris image is captured by the camera, rather than the entire iris image. In this case, the iris recognition device 100 that corrects pupil deviation based on the dominant eye becomes unable to accurately capture bilateral iris images.

[0063] To solve this problem, the iris recognition device 100 that corrects pupil deviation using the dominant eye can provide a function to adjust the user's left and right gaze using additional indicators (LEDs) 131 and 132.

[0064] The dominant eye pupil deviation correction iris recognition device 100 can activate additional indicators 131 and 132 so that the user's left eye looks at the correct position when the user, whose right eye is the dominant eye, is positioned in front of the device. The additional indicators 131 and 132 guide the user to instantly align their gaze to that position, thereby adjusting the pupil of the left eye in the correct direction (42).

[0065] With the additional indicators 131 and 132 attached to the dominant eye pupil deviation correction iris recognition device 100, the user gazes at the light source (indicator) for a while. At this moment, both of the user's eyes become aligned, and the dominant eye pupil deviation correction iris recognition device 100 can simultaneously capture bilateral iris images at the precise timing. The user focuses their gaze on the bright light of the additional indicators 131 and 132 for a while, and it can be seen that both the dominant and non-dominant eyes are precisely aligned with the camera.

[0066] The iris recognition device 100, which corrects pupil deviation using the dominant eye, can automatically turn off the additional indicator once all necessary iris images have been captured after adjusting the user's gaze.

[0067] In this method, even for users whose right eye is dominant, both iris images are perfectly captured, enabling highly reliable iris recognition. Eye alignment using additional indicators 131 and 132 allows for stable and accurate iris recognition in various user environments, thereby increasing the reliability of biometric recognition.

[0068] Figure 4 is a block diagram showing an iris recognition device that corrects pupil displacement using a dominant eye according to one embodiment of the present invention.

[0069] As shown in Figure 4, the iris recognition device 100 for correcting pupil deviation using a dominant eye according to one embodiment of the present invention may include an iris recognition unit 210, an indicator control unit 220, and an iris image capture unit 230.

[0070] The iris recognition unit 210 can recognize the user's face, the position of the pupils of both eyes, and the reflected light (SPECULAR) generated at the iris recognition position using the camera module 130.

[0071] At this time, the iris recognition unit 210 can sense the user's face using the camera module 130 and recognize the pupil positions of the left and right eyes.

[0072] For example, when a user is positioned in front of the device, the iris recognition unit 210 can detect the user's face using a camera and confirm the positions of the pupils of the left and right eyes. Through this, the iris recognition unit 210 can perform initial setup for iris recognition.

[0073] The indicator control unit 220 can activate (turn on) the iris recognition IR-LED indicator 120.

[0074] At this time, if the pupil position is recognized by the iris recognition unit 210, the indicator control unit 220 can activate (turn on) the iris recognition IR-LED indicator 120 and generate reflected light at the iris recognition position.

[0075] The iris recognition unit 210 can check whether reflected light (SPECULAR) is generated in the left and right pupils when the iris recognition IR-LED indicator 120 is activated (ON).

[0076] In this case, the iris recognition unit 210 can determine that the pupil position and the position of the reflected light are not aligned if the center position of the reflected light is more than a predetermined distance away from the center of the pupil position.

[0077] At this time, the iris recognition unit 210 can recognize the pupil, which has reflected light (SPECULAR) generated by the infrared light emitted from the IR-LED. Such reflected light can be useful in clearly distinguishing the position of the pupil from the iris image during the iris recognition process.

[0078] For example, the iris recognition unit 210 can confirm whether the reflected light is correctly aligned with both pupils.

[0079] The indicator control unit 220 can activate (turn on) the additional indicators 131 and 132 if no reflected light is detected in either of the two pupils.

[0080] For example, if the indicator control unit 220 does not detect reflected light in the right pupil, it can activate (turn on) the additional indicators 131 and 132 on the right pupil side to guide the user to accurately focus their eyes. Through this, the user's gaze can be adjusted to the correct iris recognition position.

[0081] The iris image generation unit 230 can capture iris images of both eyes if reflected light is detected in both pupils.

[0082] The iris image generation unit 230 can store iris biometric information as an iris image while ensuring the precise position of the pupil is determined by the reflected light generated by the iris recognition IR-LED indicator 120. This can then be used as data for biometric authentication.

[0083] The indicator control unit 220 can deactivate (turn off) the additional indicators 131 and 132 after the iris images of both eyes have been captured.

[0084] The stored iris image can be registered and used for user identity verification and authentication.

[0085] Figure 5 is an operation flowchart showing a method for correcting pupil displacement using a dominant eye for iris recognition according to one embodiment of the present invention.

[0086] As shown in Figure 5, the iris recognition method for correcting pupil displacement using a dominant eye according to one embodiment of the present invention can first recognize the face and pupil (S310).

[0087] In other words, step S310 uses the camera module to sense the user's face and recognize the pupil positions of the left and right eyes.

[0088] In this step, step S310 allows the user's pupils to be reflected using a half-mirror, guiding the pupil positions of both eyes to the iris recognition position.

[0089] In this step, step S310 uses a camera module to reflect the user's pupils with a half-mirror, allowing the user's face and the pupil positions of both eyes to be recognized, with the pupil positions of both eyes guided to the iris recognition position.

[0090] For example, in step S310, if the user is positioned in front of the device, the camera can detect the user's face and confirm the positions of the two pupils, the left and right eyes. Through this, step S310 can perform the initial setup for iris recognition.

[0091] Furthermore, the iris recognition method for correcting pupil deviation using a dominant eye according to one embodiment of the present invention can activate (turn on) the IR-LED indicator 120 for iris recognition (S320).

[0092] In other words, in step S320, if the pupil position is recognized in step S310, the IR-LED indicator 120 for iris recognition is activated (ON) to generate reflected light at the iris recognition position.

[0093] Furthermore, the iris recognition method for correcting pupillary deviation using a dominant eye according to one embodiment of the present invention allows for confirmation of the reflected light (SPECULAR) of the left and right pupils (S330).

[0094] In other words, step S330 allows you to check whether reflected light (SPECULAR) is generated in the left and right pupils while the IR-LED indicator 120 for iris recognition is activated (ON).

[0095] At this point, step S330 can determine whether the pupil position and the position of the reflected light can be aligned.

[0096] In this case, step S330 can determine that the pupil position and the position of the reflected light are not aligned if the center position of the reflected light is located more than a predetermined distance away from the center of the pupil position.

[0097] At this point, step S330 can recognize the pupil, which has been illuminated by the infrared light emitted from the IR-LED, generating a speculative reflection. This speculative reflection can be useful in clearly distinguishing the pupil's position from the iris image during the iris recognition process.

[0098] For example, step S330 can verify that the reflected light is properly aligned with both pupils.

[0099] Furthermore, the iris recognition method for correcting pupillary displacement using a dominant eye according to one embodiment of the present invention can activate (turn on) the additional indicators 131 and 132 on the pupil side that are not being identified (S340).

[0100] In other words, in step S340, if no reflected light was detected in either of the two pupils in step S330, the additional indicators 131 and 132 can be activated (turned ON).

[0101] For example, if no reflected light is detected in the right pupil, step S340 can activate (turn on) the additional indicators 131 and 132 on the right pupil side to guide the user to accurately focus their eyes. Through this, step S340 can adjust the user's gaze to the precise iris recognition position.

[0102] Furthermore, the iris recognition method for correcting pupillary displacement using a dominant eye according to one embodiment of the present invention can capture iris images of both eyes (S350).

[0103] In other words, step S350 can capture iris images of both eyes if reflected light is detected in both pupils in step S330 or step S340.

[0104] In this step, step S350 allows the iris biometric information to be stored as an iris image, with the precise position of the pupil ensured via the reflected light generated by the iris recognition IR-LED indicator 120. This can then be used as data for biometric authentication.

[0105] Furthermore, the iris recognition method for correcting pupil deviation using a dominant eye according to one embodiment of the present invention allows the additional indicator to be deactivated (OFF) (S360).

[0106] In other words, step S360 allows the additional indicators 131 and 132 to be deactivated (turned OFF) after the iris images of both eyes have been captured.

[0107] The stored iris image can be registered and used for user identity verification and authentication.

[0108] Figure 6 shows a computer system according to one embodiment of the present invention.

As shown in Figure 6, the computer system 1100 may comprise one or more processors 1110 communicating with each other via a bus 1120, a memory 1130, a user interface input device 1140, a user interface output device 1150, and storage 1160. The computer system 1100 may further comprise a network interface 1170 connected to a network 1180.
