Description

Artificial intelligence liquid glasses

Technical Field

The invention relates to liquid glasses, in particular to artificial intelligence liquid glasses.

Background

At present, the number of shortsightedness people in China exceeds six hundred million, wherein the number of young people accounts for one third. Since they are in their growth stage, the number of degrees increases rapidly with the increase in the axis of the eye, typically 75-125 degrees per year, requiring frequent replacement of the glasses. China has a huge presbyopia base number, is troubled by many people, shows a trend of youthfulness, and generally compensates for the weak self-adjusting capacity of presbyopia by configuring a plurality of glasses or wearing zone glasses. The users of the split-zone bifocals glasses generally look far from the upper part of the lenses and look near from the lower part, and need to change the visual field through different parts when looking at the far and near objects. However, such glasses have a limited field of vision, which can cause significant damage to vision and, in some cases, can cause dizziness and discomfort. Meanwhile, the current AR display is to display the overlay at a fixed focal plane without display in depth space, and this difference often causes dizziness, blurred vision, fatigue, nausea, etc., resulting in poor product experience. In addition, with the miniaturization and weight reduction of various devices, the current telescopic devices cannot meet the requirements of miniaturization, weight reduction and intellectualization.

Disclosure of Invention

The invention provides artificial intelligent liquid glasses. As shown in fig. 1, the glasses comprise an eyeball tracking module, a data processing module, a glasses frame, a driving module, an integrated lens screen, a semi-reflecting and semi-transmitting lens and a real capture camera.

Wherein the glasses picture frame, integrate the lens screen, half reflect half pass through the mirror, constitute artificial intelligence liquid glasses's major structure jointly. A data processing module and a driving module are embedded in the glasses leg part of the glasses frame; a pupil tracking module is embedded above the lens; there is the reality in the middle of the double pupil and catches the camera, and it is used for realizing more intelligent functions. The invention has a myopia and hyperopia correction mode, a telescopic mode and an AR self-adaptive adjustment mode.

When the artificial intelligent liquid glasses are in a myopia and hyperopia correction mode, the eyeball tracking module tracks eyeballs through the half-reflecting and half-transmitting lens and collects data of pupil diameter, pupil positions and pupil center coordinates. The real capture camera realizes synchronous measurement of the anterior ocular position through depth sensing data to determine the precise distance between the eyes and the target object. The intelligent chip in the data processing module uses an artificial intelligent correlation algorithm to carry out corresponding processing and analysis, and outputs driving data of the focal length required by correcting the myopia and the hyperopia. The driving module drives according to the data, so that the curvature of the liquid lens is changed, and the diopter compensation of myopia or hyperopia meeting the eye requirements is obtained.

When the artificial intelligence liquid glasses recognize that the pupil size exceeds a certain value and keeps for a certain time, the artificial intelligence liquid glasses are switched from a normal mode to a telescopic mode. And in the telescopic mode, the intelligent chip in the data processing module performs corresponding processing and analysis by using an artificial intelligent correlation algorithm and outputs driving data of the required focal distance for telescopic. Because the telescopic distances are different, the diameters of pupils are different, and corresponding driving parameters are also different, the telescopic with different magnification factors can be realized.

When the artificial intelligence liquid glasses are in an AR self-adaptive adjustment mode, the real capture camera is used for acquiring external images and data, the data processing module is used for carrying out image recognition and intelligent analysis, and the analysis result is used for carrying out drive control on the integrated lens screen to realize real-time display.

Preferably, the data collected by the eyeball tracking module comprises the diameter size of the pupil, the pupil position and the pupil center coordinate.

Preferably, the driving method of the variable focus spectacles is electrowetting, dielectric force, electromagnetic force, mechanical force, or the like.

Preferably, the diameter of the variable focus spectacles is between 30mm and 50 mm.

Detailed Description

To further understand the structure and function of the present invention, an artificial intelligence liquid glasses will be further described with reference to the following embodiments. It should be noted that the following examples are only for illustrative purposes and should not be construed as limiting the scope of the present invention, and that the skilled person in the art may make modifications and adaptations of the present invention without departing from the scope of the present invention.

As shown in fig. 1, the intelligent variable focus glasses of the present invention includes an eyeball tracking module 1, a data processing module 2, a glasses frame 3, a driving module 4, an integrated lens screen 5, a semi-reflective and semi-transparent lens 6, and a real capture camera 7.

Take artificial intelligence liquid glasses based on electrowetting drive as an example, wherein, eyeball tracking module 1 can be realized by raspberry pi + OpenCV + high definition wide-angle camera, but is not limited to use raspberry pi + OpenCV + high definition wide-angle camera. The system tracks the eyeball and collects the diameter of the pupil, the position of the pupil, the coordinate of the center of the pupil and other related data. The intelligent chip of the data processing module 2 can use an ARM chip, but is not limited to use of the ARM chip. The intelligent chip uses an artificial intelligent correlation algorithm to carry out corresponding processing and analysis, and obtains the lens driving voltage and a data result required by real-time display. The driving module 4 realizes the driving control of the voltage and the display driving control of the integrated lens screen 5 according to the intelligent analysis result of the data processing module 2. The integrated lens screen 5 takes an AR display screen as a substrate, and is filled with two kinds of transparent liquid with equal density, wherein the filling liquid can be silicone oil, electrolyte liquid, ionic liquid and the like, and a liquid-liquid interface is formed inside the integrated lens screen. When the driving voltage provided by the driving module 4 at both ends thereof is changed, the contact angle of the two liquids is also changed, thereby changing the curvature of the liquid-liquid interface and realizing zooming. The substrate AR screen in the integrated lenticular screen 5 can be implemented using, but is not limited to, an OLED screen. The reality capturing camera 7 acquires the depth information of the target object and also acquires the picture content of the target object.

After wearing this artificial intelligence liquid glasses, glasses get into operating condition, when eyeball tracking module 1 tracked the eyeball, gathered eyeball relevant data, and the reality is caught camera 7 and is also carried out depth data and gather picture. The two data are transmitted into the data processing module 2 to be intelligently identified, analyzed and processed, and the diopter size which needs to be adjusted when the human eyes clearly see the target object and the zoom range which can be independently provided by the human eyes at present are judged, so that the focal length value which needs to be compensated by the integrated lens screen 5, the corresponding driving data and the data which needs to be displayed in real time are obtained. The driving module 4 performs driving control on the integrated lens screen 5 according to the above, and realizes the zooming function and the real-time display function of forming clear images of the eyeballs.

The invention can not only replace single or multiple fixed focus glasses, but also realize the functions of telescope vision aid and real-time AR display. When the diameter of the pupil is within the range of 2-4mm, namely, under the myopia and hyperopia correction mode, the data collected by the eyeball tracking module 1 and the reality capturing camera 7 are intelligently analyzed by the data processing module 2 to realize the process, and diopter compensation is carried out on the myopia or hyperopia, so that the retina can be clearly imaged and displayed in real time, and the compensation can be subjected to real-time feedback updating. Myopic diopter compensation is shown in figure 2. When the eyeball keeps a certain state for more than 5s, the eyeball tracking module 1 automatically identifies the size of the pupil through the half-reflecting and half-transmitting mirror 6. If the size of the pupil exceeds 5.8mm, the data processing module 2 can judge that the state belongs to the telescopic state and transmit the analysis result to the driving module. The driving module outputs corresponding driving control voltage and displays required data in real time, so that the focal length and the display result of the integrated lens screen are changed. After the above adjustment process, the light is converged to the retina through the artificial intelligence liquid glasses and the human eyes to form a telescopic image, as shown in fig. 3.

Fig. 4 is a graph showing diopter of the integrated lens panel and variation of driving voltage applied thereto.

The artificial intelligent liquid glasses provided by the invention can actively adjust the degree in real time according to the vision condition of an individual, perform vision compensation, improve the vision and obtain a clear image. Besides self-adaptive zooming, the artificial intelligent liquid glasses can also realize the projection effect of deeper space and more layers, and multiple functions such as real-time data display function, simulated 3D glasses function, translation function, navigation function and the like.
