All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The general head-mounted display equipment does not have degrees, and a myopia person needs to additionally wear a pair of glasses while using the head-mounted display equipment, so that the burden of eyes is increased, and the experience of the head-mounted display equipment is influenced; the head-mounted display equipment with a fixed degree can only be used by people with the same myopia degree. In order to solve the above problems, a head-mounted display device provided in the related art can achieve degree adjustment, and needs manual degree input for automatic adjustment, so that user experience is poor.
Based on the above technical problem, the present embodiment provides a power adjusting method, which can be applied to AR glasses, VR glasses and MR glasses, and the following embodiments take AR glasses as an example for description. According to the method, the automatic adjustment of the glasses can be realized without manually inputting the degrees, the accuracy of degree determination is high, the customer experience is improved, and specifically, referring to fig. 1, fig. 1 is a schematic flow diagram of a degree adjustment method provided by an embodiment of the application, and specifically includes:
s101, when the fact that the user wears the glasses is detected, displaying a corrected image.
In this embodiment, the detection method is not limited. The glasses can be provided with a pressure sensor, and when pressure data sent by the pressure sensor is received, whether the glasses are worn or not is determined according to the pressure data. Further, determining whether to wear the eyewear based on the pressure data includes: when the pressure data is larger than the preset pressure threshold value, the glasses are determined to be worn, and when the pressure data is not larger than the preset pressure threshold value, the glasses are determined not to be worn by the user. The glasses can be further provided with an infrared sensor, when infrared data sent by the infrared sensor are received, the distance is determined based on the infrared data, and whether the glasses are worn or not is determined based on the distance. Further, determining whether to wear the glasses based on the distance includes: when the distance is smaller than the preset distance threshold, the user is determined to wear the glasses, and when the distance is not smaller than the preset distance threshold, the user is determined not to wear the glasses. It is understood that the case where the user does not wear the glasses determined in the above manner includes the case where the user does not wear the glasses and the case where the user does not wear the glasses regularly.
The corrected image includes, but is not limited to, an image in the eye chart, and may be another image as long as the object of the present embodiment can be achieved. It will be appreciated that each of the corrected images corresponds to a degree, for example, corrected image 1 corresponds to degree 1 and corrected image 2 corresponds to degree 2.
In this embodiment, after the user wears glasses, the correction image can be played automatically, that is, the correction image can appear on the glasses lens (AR glasses lens), the AR glasses can virtually image in real life, and the correction image can be set to be a virtual image (distance for testing eyesight) at a position 3 meters away from the person.
Further, in order to ensure the accuracy of the target power determination, when it is detected that the user wears glasses and displays the corrected image, the method further comprises the following steps: judging whether the current wearing state of the glasses is a stable state or not; if the wearing state is a stable state, the corrected image is displayed.
When the user wears the glasses and the human eyes are kept relatively stable, the current wearing state is determined to be a stable state, the corrected image is automatically played, and the corrected image appears on the AR glasses. Only when the glasses of the user are worn stably, the observation result obtained by observing according to the displayed correction image is more accurate, and the acquired eye state is more accurate. Further, determining whether the current wearing state of the glasses is a stable state includes: the method comprises the steps of obtaining an image of an eye contour of a user, determining that the current wearing state is a stable state if the change of the relative position of the eye contour of a continuous preset frame number is within a preset change range, and determining that the current wearing state is an unstable state if the change of the relative position of the eye contour of the continuous preset frame number is not within the preset change range any more. It can be seen that, the display of the corrected image is only performed when the current wearing state of the glasses of the user is a stable state, so that the user can observe more accurately, and the collection of the eye state is more accurate.
In an implementable embodiment, to simplify the calculation process, when it is detected that the user wears glasses, the corrected image is displayed, comprising: and when the user wearing the glasses is detected, sequentially displaying the corrected images.
In this embodiment, one corrected image is displayed in the glasses each time, that is, the corresponding corrected images are sequentially displayed according to the degree of vision from low to high, further, when the corrected images are changed, a preset action of the eyes of the user may be acquired, for example, when the corrected image 1 is displayed, the camera acquires an image of a preset number of blinks of the user, that is, when the user cannot see the corrected image, the next corrected image is displayed. Of course, other actions of the eyes may be detected, and the user may customize the setting as long as the purpose of the present embodiment can be achieved. Further, when the human eye state is in a preset state, determining a target correction image, including: when a preset correction image is displayed, the state of human eyes is collected; detecting the human eye state, determining that the user can clearly see the corrected image if the human eye state is in a preset state, and taking the corrected image as a target corrected image. It can be seen that, in the embodiment, by sequentially displaying the corrected images, the degree can be determined by the corrected images, and the method is simple.
In another implementable embodiment, to reduce waste of time and improve efficiency, when it is detected that the user wears glasses, a correction image is displayed, comprising: when detecting that the user wears the glasses, displaying all the corrected images; correspondingly, when the human eye state is in a preset state, determining a target correction image, including: when the human eye state is in a preset state, acquiring a human eye image; determining the target position of the iris center point relative to the glasses contour by utilizing an image analysis technology based on the human eye image; a target corrected image is determined from all the corrected images based on the target position.
When detecting that a user wears glasses, displaying all correction images, namely setting all correction images as virtual patterns at a position which is about 3 meters away from the user (the distance of testing vision, the correction images with different sizes are distributed on all the directions of the images and are used for correcting the vision of the human eyes, and the correction images do not need to be displayed in sequence, so that the time for determining the vision is saved, correspondingly, when the state of the human eyes is in a preset state, carrying out image analysis through an image processing technology according to the image data of the human eyes to determine the position of an iris central point relative to the outline of the eyes and recording the position of the eye orientation, calculating pattern information according to the position of the eye orientation to obtain a target correction image, and obtaining the calibration degree, namely the target degree based on the target correction image, storing information related to the calibration image in the glasses, wherein the information comprises comparison table information of the patterns and the degrees, and the like, when the specific state of the human eyes can be a, then an image of the human eye is acquired, and according to the orientation position of the eye, which corrected image the human eye looks at when the human eye is still is analyzed and calculated. Specifically, obtaining the target power according to the determined target correction image may be calculating the eye power according to a comparison table of the correction image and the power when the information of the target correction image includes the calibration mark, where the power is the target power. As can be seen, in the present embodiment, by displaying all the corrected images at one time, the problem of time increase caused by displaying a single corrected image is avoided, and although the tracking determination of the target position needs to be performed, the calculation time is short, so that the technology provided by the present embodiment can effectively reduce the time and improve the efficiency of determining the target degree.
S102, acquiring the state of human eyes by using a camera, and determining a target correction image when the state of the human eyes is in a preset state, wherein the correction image comprises a target correction image.
In the embodiment, the preset state is not limited, and the preset state may be a preset time for which the human eye keeps still on the target correction image, or may be a preset number of blinks for which the time for which the human eye keeps still on the target correction image exceeds the preset time; of course, other states are also possible, and the user can customize the setting as long as the purpose of the present embodiment can be achieved. The specific method for determining the state of the human eye is in the preset state is not described in detail in this embodiment.
The camera automatically captures the state of human eyes, the human eyes scan the correction images presented on the glasses, and when the correction images which can just be seen clearly are found, the eyes stay on the correction images for a certain time so that the system can judge and process. The specific determination method comprises the following steps: when the system enters timing judgment, the camera periodically scans the state of the human eyes, and when the human eyes are found to be out of the set time threshold range, the glasses are always in a static state, and the system considers the corrected image as a target corrected image of subsequent calibration processing; otherwise, if the eyes move within the time threshold range, timing judgment is carried out again, and the time threshold is set according to the actual debugging condition. The corrected image comprises corrected images corresponding to a plurality of degrees.

The glasses are provided with a driving device, and after the target power of the wearer is determined, the controlled driving device can drive the convex-concave lens on the lens to move according to the calculated data so as to enable the convex-concave lens to reach the required power.
When the degree of the glasses is the first degree, calculating the difference value between the first degree and the target degree; and determining the movement distance according to the difference, the preset difference and the movement relation, controlling the driving device to move according to the movement distance so as to realize the movement of the lens, and adjusting the degree of the eyes to the target degree from the first degree. For example, if the number of degrees of the glasses is 0 and the target number of degrees is 100, the difference value is-100, the movement distance is determined to be a according to the preset difference value and the movement relation, and the lens is controlled to move based on a; for example, the power of the eye is 200, the target power is 100, the difference value is 100, the movement distance is determined as b from the preset difference value and the movement relation, and the lens movement is controlled based on a.
In an implementable embodiment, to simplify the target degree obtaining method, the present embodiment employs a process of target degree determination, wherein the target degree is determined based on the target correction image, including: acquiring image information corresponding to a target correction image; and analyzing the image information to obtain the target degree.
In the embodiment, image information is set for each correction image, and the image information includes, but is not limited to, corresponding degrees, so that the target degrees are obtained by analyzing the image information, the method is simple, and the target degrees can be quickly determined.
In another implementable embodiment, in order to simplify the target degree obtaining method, the present embodiment employs a process of target degree determination, wherein the target degree determination based on the target correction image includes: acquiring an image identifier corresponding to a target correction image; and matching the image identification with the image degree correlation information to obtain a target degree.
In this embodiment, each corrected image is provided with an image identifier, which may be in the form of letters, numbers, and the like, image degree association information is preset in the system, and the image identifier and the image degree association information are matched to obtain a target degree, for example, the preset image degree association information includes a degree 1 corresponding to the image identifier 1, a degree 2 corresponding to the image identifier 2, and a degree 3 corresponding to the image identifier 3. And when the image identifier 2 corresponding to the target correction image is obtained, obtaining the target degree as degree 2 based on the preset image degree correlation information. Therefore, in the embodiment, the image and the image identifier are associated, and the degree corresponding to the image identifier is determined according to the preset image degree relation information, so that the target degree is obtained, and the calculation is simple.
Therefore, the target degree can be automatically obtained, the degree of the glasses can be automatically adjusted, manual control is needed, the use is convenient, and the experience effect is improved; this embodiment can be according to the automatic adjustment glasses degree of the person's of wearing eyes situation, and the simple structure of this glasses, convenient to use is swift, is applicable to all crowds.

When the glasses are worn, all the corrected images, which may be eye charts or the like, appear automatically in the lenses. The correction images with different degrees are distributed at different positions on the correction sheet. Each correction image is different and one for each correction image is the number of optotypes. The wearer can scan the correction image on the correction picture according to a certain rule until a certain correction image is clearly seen. When a clear correction image is found, the human eye needs to observe the correction image for a certain time while keeping still.
During the period from the time when the user wears the glasses to the time when the user finds out the clearly corrected image and stops, the camera continuously scans the state of the user's eyes in the same time interval. When the human eyes are still, the needed correction image is considered to be found at the moment, and the camera captures the position state of the human eyes at the moment. When the human eye is still, the central point of the iris moves in a certain direction in the eye. The eye orientation position is calculated by image processing techniques. And calculating the position of the corrected image which is clearly seen by human eyes according to the orientation position of the eyes. At this time, the eye approximation degree of the person wearing the human body, namely the target degree, is calculated according to the corrected image and the comparison table of the pattern and the degree.
