In some embodiments, the optical correction device 100 may be applied to a wearable device, such as AR, VR, MR glasses, and the like. When the user uses the wearable device, the visualization optical mechanical module 10 may be located in front of both eyes of the user (including a front or an area having a certain offset distance with respect to the front, such as left front, right front, upper front or lower front) to ensure that the user can better see the displayed image of the visualization optical mechanical module 10; the data acquisition device 20 may be located in a first predetermined region corresponding to the dual purpose of the user, for example, a peripheral region of a frame of the image development optical-mechanical module 10, or a position near the bridge of the nose corresponding to the user when the user uses the wearable device, so as to ensure that the data acquisition device can accurately acquire the dual purpose vision condition data of the user, such as myopia data, hyperopia data, and the like.

In some embodiments, the vision condition data may include at least one of myopia data, hyperopia data, presbyopia data, and astigmatism data.

The data acquisition device 20 may be used to acquire and obtain vision condition data of the user according to the physiological condition of the eyes of the user. In some embodiments, the data acquisition device 20 may include at least a vision correction device 21. More specifically, in some embodiments, the vision correction apparatus 21 may include at least one of an eye tracking sensor 211 and an eye gaze sensor 212. In some embodiments, at least one of the eye tracking sensor 211 and the eye gazing sensor 212 may be configured to collect binocular physiological response data of the user to the image displayed by the visualization optical mechanical module 10, such as pupil size change, and obtain the vision condition data of the user based on the physiological response of the user to the image displayed by the visualization optical mechanical module 10 and the image parameters displayed by the visualization optical mechanical module 10.

In some embodiments, the vision condition data collected by the data collection device 20 may be sent to the controller 30 for processing to determine the current user's vision condition. After determining the vision condition of the current user, the controller 30 may determine or obtain optical correction adjustment data based on the vision condition of the current user, and then control the visualization optical-mechanical module 10 to display a corresponding image based on the optical correction adjustment data.

In some embodiments, the controller 30 is configured to match the corresponding vision correction image according to the vision condition data, and obtain the optical correction adjustment data according to the matched corresponding vision correction image, and the visualization optical mechanical module 10 displays the matched vision correction image according to the optical correction adjustment data. For example, when the current user's eyesight is determined to be 500 degrees myopia, the controller 30 controls the imaging opto-mechanical module 10 to display an eyesight correction image frame with 500 degrees myopia; when the user's eyesight is determined to be 200 degrees far, the controller 30 controls the image processor module 10 to display an image of the eyesight correction image with 200 degrees far.

In some embodiments, the vision correction image displayed by the image development optical-mechanical module 10 and matched with the vision condition of the current user may be pre-stored, or may be obtained by processing the original image in real time according to the vision condition of the current user. In some embodiments, the vision correction image that matches the current user's vision condition may be processed in conjunction with a model algorithm, such as a machine learning model or the like. Through the corresponding vision correction image of concrete vision situation data matching, to the corresponding image that different users pertinence ground clear display accords with its vision situation, satisfy different user demands, can make the user that has visual disorder (for example myopia, hyperopia, astigmatism etc.) can see clearly under the condition of not wearing vision correction devices such as glasses and develop the demonstration image of ray apparatus module 10, improved user's use experience in the very big degree.

In some embodiments, the binocular parameters of the current user may be obtained from the cloud, and the blur kernel matching the binocular parameters in the vision status data may be determined: deconvoluting the target image by using the fuzzy core to obtain a vision correction image: the vision correction image is output to the controller 30, so that a vision correction image with higher accuracy and matching degree is obtained. Like this, the user sees the image that the eyesight of display device demonstration when correcting the image in the condition of bore hole, compares in the current correction mode of wearing the equipment in addition correction lens, need not to carry out the hardware adjustment to display device, and when reduce cost, keep the laminating of display device and user's skin to increase and immerse the sense, further improved user experience.

In some embodiments, the binocular parameter may be at least one of diopter, interpupillary distance, refractive index, astigmatic axial power, and interpupillary distance of both eyes. In some embodiments, when the target image is deconvoluted by using the blur kernel, the calculated RGB values may not be in the normal range that the human eye views, for example, the calculated RGB values are negative or larger positive values, so to form an image that can be viewed by the human eye, after the target image is deconvoluted by using the blur kernel and a deconvoluted image is obtained, the deconvoluted image may be normalized to obtain a vision correction image in which the RGB values of the pixels are all in the normal range that the human eye views.

In some embodiments, the aforementioned blur kernel may be constructed based on coefficients of terms in a zernike polynomial: and the coefficients of all terms in the Zernike polynomials are determined by the binocular parameters corresponding to the fuzzy core. In some embodiments, the zernike polynomial may include a plurality of terms, e.g., a focus term, an astigmatism term, a defocus term, a coma term, a translation term, a horizontal tilt term, a vertical tilt term, etc., each having a corresponding coefficient. Due to the fact that binocular parameters of different users are different, coefficients of all items in a Zernike polynomial describing human eyes are different, and an image perceived by naked eyes of the users is equivalent to a blurred image formed after a clear target image is subjected to blurring kernel convolution.

In some embodiments, a large number of binocular parameters and corresponding fuzzy kernels thereof may be used as training samples to construct a fuzzy kernel training model, so that the corresponding fuzzy kernels can be calculated efficiently and accurately based on the binocular parameters in the following.

In some embodiments, the data acquisition device 20 can continuously acquire the vision condition data of the user while the visualization optical mechanical module 10 displays the vision correction image picture matched with the vision condition of the current user, and dynamically adjust the display image of the visualization optical mechanical module 10 based on the vision change condition of the user in the using process.

Referring to fig. 2, in some embodiments, the mirror holder of the visualization opto-mechanical module 10 may be located at a lower portion of the visualization opto-mechanical module 10. In some embodiments, the vision correction device 21 may include two mounts (two carrier substrates may be employed) for mounting the eye tracking sensor 211 and the eye gaze sensor 212. In some embodiments, at least one eye tracking sensor 211 and at least one eye gaze sensor 212 may be mounted on each mount. In some embodiments, the two brackets may be hinged or slidably engaged with the frame of the visualization opto-mechanical module 10, so that the two brackets may be rotatably adjusted relative to the frame of the visualization opto-mechanical module 10, respectively, to adjust the dual-purpose viewing angle of the eye tracking sensor 211 and the eye gaze sensor 212 relative to the user, so as to ensure that the physiological change of the eyes of the user can be accurately collected.

In some embodiments, the position of two supports contact user's bridge of the nose can include to have elastic laminating structure, for example soft package of sponge, elasticity rubber etc to promote the wearing experience of user when using, avoid wearing for a long time and arouse the contact site discomfort afterwards.

With continued reference to fig. 2, in some embodiments, the data acquisition device 20 may include an iris recognition device 22, and the iris recognition device 22 may be used to match and recognize iris information of the user, and obtain user identity information through iris recognition to facilitate confirmation of the user identity. In some embodiments, the iris recognition device 22 may be disposed in a second predetermined area of the frame of the visualization optical mechanical module 10 corresponding to the user's dual purpose, such as near the vision correction device 21. In some embodiments, the iris recognition device 22 may be disposed between the vision correction device 21 and the display area of the visualization optical machine module 10.

In some embodiments, the iris recognition device 22 may include an optical lens (not shown) for imaging the iris on an image sensor (not shown) for acquiring an iris image. An image sensor may be communicatively coupled to the controller 30, and the image sensor may convert the iris image into a digital signal and transmit the digital signal to the controller 30. Further, the controller 30 may be configured to extract iris feature information according to the received digital signal, and perform user identity matching and identification according to the iris feature information.

FIG. 3 is a block diagram of a controller in an optical correction device according to some embodiments of the present application. Referring to fig. 3, in some embodiments, the controller 30 may include a fatigue determination unit 31 and a vision verification processing unit 32.

In some embodiments, the vision verification processing unit 32 may be configured to process the identity information obtained after matching and recognizing according to the iris information and the vision condition data of the user obtained through the foregoing processes to obtain vision verification result information. Further, the controller 30 may be configured to obtain optical correction adjustment data according to the vision condition data and the vision verification result information, and control the image development optical-mechanical module 10 to perform corresponding image display based on the optical correction adjustment data.

In some embodiments, after determining the identity information of the user according to the iris information, the controller 30 may search a database (including a local database or a remote database) for a preset operating parameter (or a historical operating parameter, such as vision condition data, etc.) matching the iris information, and control the development opto-mechanical module 10 to perform a corresponding image display based on the searched preset operating parameter. For example, when the current user is identified as the user a through the iris information, the controller 30 may search the working parameters corresponding to the user a from the database, and if the vision condition data of the user a in the historical use process is found to be 300 degrees of myopia, the controller 30 may control the development optical mechanical module 10 to display an image frame matched with 300 degrees of myopia. Because the safety detection technology based on the iris in the eyes for identity recognition has higher accuracy and superiority compared with the current popular biometric identification technologies such as fingerprint recognition, face recognition and the like, the method can omit the process of detecting the vision condition of the user, thereby saving the processing resources of the controller 30 to a certain extent and further improving the processing efficiency.

In some embodiments, eye tracking sensor 211 may comprise an eye tracking sensor that may be used to acquire user eye change data or user pupil change data. The fatigue determination unit 31 may determine or acquire fatigue state data according to the user eyeball variation data and/or the user pupil variation data, and determine whether the current user is in a fatigue state. In some embodiments, the image development optical-mechanical module 10 can perform corresponding adjustment operations on the display image thereof according to the fatigue state data, such as adjusting the display brightness, pausing the image display image, and the like. The fatigue state of the user is obtained through monitoring data of the eye movement state of the user, so that the fatigue is relieved through display adjustment, and the user experience is further improved.

In some embodiments, in order to avoid the problem that the displayed image is not matched with the user's eyesight due to the above method, after the user's historical eyesight condition data is used to show a corresponding picture to the user, the user's eyesight condition data may be continuously collected, and the displayed image of the development opto-mechanical module 10 may be dynamically adjusted based on the real-time collected eyesight condition data.
