Lock method, tripper and the AR glasses of AR glasses.
To unlock AR using iris to a kind of disclosed in the embodiment of the present invention first convenient for understanding the present embodiment
The method of glasses describes in detail.
Embodiment one
A kind of method using iris unlock AR glasses provided in an embodiment of the present invention, is applied to AR glasses.For example, working as AR
When glasses are worn or when unlock operation carries out, start iris recognition program.As shown in Figure 1, this method comprises the following steps:
Step 102, the iris image of user is acquired by image acquisition device.
Wherein, image acquisition device can be camera or iris scan sensor.Specifically, image acquisition device may include
One or at least two cameras, alternatively, image acquisition device may include one or at least two iris scan sensors.
Step S104 extracts the iris information of user from the iris image of acquisition.
Since iris area itself is small, the variation of illumination, the interference of noise, the blocking of photographer's eyelashes and eyelid, pupil
The scaling in region can all cause the image of acquisition imperfect, and the accuracy that may result in iris recognition is low.It therefore can be to rainbow
Film image is pre-processed, to improve the discrimination of iris information in image.The pretreatment includes at enhancing processing or denoising
Reason.The enhancing processing, includes at least: any one of contrast adjustment or smoothness adjusting are multinomial.For example, can use
Trained depth convolutional neural networks model carries out denoising to iris image and details enhancing is handled.
Pretreated iris image is normalized.Normalization is exactly (to utilize figure by a series of transformation
The not bending moment of picture, which finds one group of parameter, can eliminate the influence that other transforming function transformation functions convert image), by original to be processed
Beginning image be converted into corresponding sole criterion form (the canonical form image to translation, rotation, scaling equiaffine transformation and it is trapezoidal
Distortion correction has invariant feature).
Image normalization technology basic functional principle based on square are as follows: constant first with having in image to affine transformation
Property square determine the parameter of transforming function transformation function, original image is transformed to a mark by the transforming function transformation function then determined using this parameter
The image of quasi- form (image is unrelated with affine transformation).It is, in general, that the image normalization processes based on square include 4 steps
Suddenly, i.e., coordinate centralization, x-shearing are normalized, scaling normalizes and rotational normalization.
Image normalization allows image to resist the attack of geometric transformation, and it is constant that those of it can find out in image
Amount, to learn these images originally and be exactly that the same or one serial.Normalized mainly includes based on gray scale ladder
The method of degree and method based on binary border point.The method based on shade of gray includes calculus methods.It is described to be based on
The method of binary border point includes least square method and Hough transform.
It is illustrated so that image acquisition device includes one or at least two cameras as an example, when image acquisition device includes one

When image acquisition device only includes a camera, the eye of user may the face camera, it is also possible to take the photograph
As being angularly offset between head.Therefore, if image acquisition device includes a camera, the bat of the camera can be first determined
Take the photograph angle.The shooting angle of camera is camera between the line of eye central point and the central axes of camera of user
Angle.Specifically, the bat of camera can be determined by position of the eye central point of user in the image that camera is shot
Take the photograph angle.For example, if the eye center of user in the left side of image center, illustrates that camera is located at the eye of user
Right side；If the eye center of user in the downside of image center, illustrates that camera is located at the upper of the eye of user
Side.According to the relative position between the eye central point and image center of user, the eye of camera to user can be determined
Angle between the line of portion's central point and the central axes of camera.After the shooting angle for determining camera, according to camera
Shooting angle, to camera shooting image be normalized, eliminate shooting when camera and the eyes of user between
Inclination effect obtains the iris image of user.Normalized includes at least: image scaling, position adjusting, angular adjustment or bright
Any one of degree adjusting is multinomial.
When image acquisition device includes at least two camera, camera can be uniformly distributed on a circumference, acquisition
When client iris image, user can be prompted to be placed in eye in the circumference of camera formation.Camera will be from different angles
Degree shooting, obtains multiple iris images.It therefore, can be respectively to camera shooting if image acquisition device includes at least two cameras
The image zooming-out eye feature point of head shooting, the eye feature point of extraction is matched, identical eye feature point is closed
And and then it is spliced into the iris image of user.
Iris Location identification is carried out to the iris image after normalized, the image of the iris region is extracted, goes
Fall extra background image.The eye structure of people is made of the part such as sclera, iris, pupil crystalline lens, retina.Iris is position
Annular formations between black pupil and white sclera.Inner circle, outer circle can be determined in iris image after the pre-treatment
With the position of conic section in the picture.Wherein, the inner circle is the boundary of iris and pupil, and the outer circle is iris and sclera
Boundary, the conic section be iris and upper lower eyelid boundary.
In addition, since different shooting times, shooting distance or shooting angle can make the image of shooting of different sizes, it can
To adjust to the fixed dimension of setting, the image generated when being shot with eliminating is big by the way that iris image is normalized
The disturbing factors such as small difference, angle difference.Iris image is normalized, further includes: iris image is cut and is tiled,
Lines after cutting tiling is digitally converted into fixed-size image.
It include the minutia of many interlaced spot, filament, coronal, striped, crypts etc. in the iris of people.Rainbow
Film will be to maintain constant after prenatal development stage is formed in entire life course.These features determine iris feature
Uniqueness, therefore be determined for the identity of user.For example, can be extracted from iris image using specific algorithm
