In order to better understand the technical scheme of the application, intelligent glasses in some technologies are briefly introduced here. The intelligent glasses comprise a main control device and a glasses assembly; the main control device comprises a main control chip, and the main control chip is used for processing signals transmitted by the glasses component and controlling the glasses component. The glasses assembly comprises a display screen and a camera, wherein the display screen is used for receiving and displaying image information transmitted by the main control chip, and the camera is used for receiving and shooting control signals transmitted by the main control chip.

In the embodiment of the application, the main control device comprises a screen brightness adjusting chip, and the screen brightness adjusting chip can execute the screen brightness adjusting method of the intelligent glasses provided in the embodiment of the application. The camera in the glasses assembly can receive the control signal of the screen brightness adjusting chip to shoot. Optionally, the screen brightness adjusting chip may be externally arranged on the intelligent glasses, and is connected with the intelligent glasses in a wired or wireless manner, so as to execute the screen brightness adjusting method of the intelligent glasses provided by the embodiment of the application.

Example 1

Fig. 1 is a flowchart illustrating a method for adjusting screen brightness of smart glasses according to an embodiment of the application. The screen brightness adjusting method of the intelligent glasses provided by the embodiment of the application comprises the following steps:

s10: when a user wears the intelligent glasses, a first screen brightness value of the intelligent glasses and a first pupil diameter of the user are obtained.

In the embodiment of the application, the first screen brightness value is the current screen brightness value of the display screen of the intelligent glasses when the user wears the intelligent glasses. The screen brightness adjusting chip can acquire a first screen brightness value from the main control device of the intelligent glasses, and specifically, the main control device of the intelligent glasses is connected with the display screen, so that the screen brightness value of the display screen can be acquired in real time. The screen brightness adjusting chip can also directly acquire the first screen brightness value from the display screen of the intelligent glasses.

The first pupil diameter is the current pupil diameter of the user under the action of the current screen brightness of the intelligent glasses and the brightness of the external environment when the user wears the intelligent glasses. The screen brightness adjusting chip can be started by controlling the camera so as to collect eyeball images of a user, and the pupil diameter of the user is obtained from the eyeball images by utilizing an image recognition and image segmentation algorithm.

Specifically, the screen brightness adjusting chip periodically controls the starting of the camera, so that the first pupil diameter is periodically obtained.

S20: obtaining a second pupil diameter corresponding to the first screen brightness value according to a preset mapping relation between the screen brightness value and the pupil diameter; the second pupil diameter is used for indicating the pupil diameter corresponding to the first screen brightness value when the user wears the intelligent glasses under the condition that no ambient light is interfered.

It can be understood that one screen brightness value in the preset mapping relationship between the screen brightness value and the pupil diameter corresponds to a unique pupil diameter, and the pupil diameter in the mapping relationship is the pupil diameter corresponding to the user wearing the intelligent glasses only under the action of the screen brightness under the condition that no ambient light is interfered. In fact, the absence of ambient light interference is an ideal situation, where ambient light interference can be reduced as much as possible.

Specifically, the outside ambient light around the display screen of the smart glasses is shielded, for example, after the user wears the smart glasses, the eye cover is worn again, and the outside light entering the eyeballs of the user is shielded through the eye cover, so that the pupil diameter under the effect of the current screen brightness of the smart glasses is obtained.

After the first screen brightness value is obtained, a corresponding second pupil diameter can be obtained according to the mapping relation,

In the embodiment of the application, the second pupil diameter is different from the first pupil diameter, and is the pupil diameter of the user only under the current screen brightness effect of the intelligent glasses when the user wears the intelligent glasses.

S30: and if the deviation between the first pupil diameter and the second pupil diameter is not in the preset threshold range, adjusting the screen brightness of the intelligent glasses.

The pupil diameter of the human eye is related to the brightness of the light entering the human eye. In a scene of wearing the intelligent glasses, the brightness of light entering human eyes is divided into two parts, wherein one part is the screen brightness of the intelligent glasses, the screen brightness is fixed, the other part is the external environment brightness, and the external environment brightness is changed. Therefore, in the case of knowing the screen brightness of the smart glasses, the change in the pupil diameter of the human eye can be regarded as a change caused by the external environment brightness.

In the embodiment of the application, the first pupil diameter and the second pupil diameter have deviation, namely the difference exists between the current screen brightness of the intelligent glasses and the external environment brightness. If the deviation between the first pupil diameter and the second pupil diameter is not within the preset threshold range, the fact that the difference between the current screen brightness of the intelligent glasses and the external environment brightness is large is indicated, and the current screen brightness of the intelligent glasses needs to be adjusted so that the difference between the adjusted screen brightness of the intelligent glasses and the external environment brightness is within a preset range is indicated.

And adjusting the screen brightness of the intelligent glasses according to the deviation between the first pupil diameter and the second pupil diameter. Specifically, the target screen brightness corresponding to the first pupil diameter can be determined according to the deviation between the first pupil diameter and the second pupil diameter, and the screen brightness of the intelligent glasses is adjusted from the current screen brightness to the target screen brightness. The adjustment direction of the screen brightness of the intelligent glasses can be determined according to the deviation between the first pupil diameter and the second pupil diameter, and the screen brightness of the intelligent glasses is adjusted according to the adjustment direction and the preset screen brightness adjustment step length.

If the deviation between the first pupil diameter and the second pupil diameter is within the preset threshold range, the screen brightness of the intelligent glasses does not need to be adjusted.

By applying the embodiment of the application, the first screen brightness value of the intelligent glasses and the first pupil diameter of the user are obtained when the user wears the intelligent glasses; obtaining a second pupil diameter corresponding to the first screen brightness value according to a preset mapping relation between the screen brightness value and the pupil diameter; the second pupil diameter is used for indicating the pupil diameter corresponding to the first screen brightness value when the user wears the intelligent glasses under the condition that no ambient light is interfered; and if the deviation between the first pupil diameter and the second pupil diameter is not in the preset threshold range, adjusting the screen brightness of the intelligent glasses. According to the embodiment of the application, the screen brightness of the intelligent glasses is regulated according to the pupil diameter, and an additional light sensor is not required to be installed, so that the cost is reduced.

In an optional embodiment, step S20 includes steps S11 to S12 before the step of obtaining the second pupil diameter corresponding to the first screen brightness value according to the preset mapping relationship between the screen brightness value and the pupil diameter, specifically as follows:

s11: under the condition of no ambient light interference, acquiring a plurality of pupil diameters corresponding to a plurality of screen brightness values when a user wears intelligent glasses;

In the embodiment of the application, after the user wears the intelligent glasses, the user wears the eyeshade, so that the interference of external environment light is minimized. And determining the upper limit and the lower limit of the screen brightness value of the intelligent glasses to obtain the adjustment range of the screen brightness value of the intelligent glasses. And randomly selecting a plurality of screen brightness values from the adjustment range, controlling the screen brightness of the intelligent glasses to be the selected plurality of screen brightness values respectively, and recording the user pupil diameter corresponding to each screen brightness value. Or selecting a plurality of screen brightness values from small to large or from large to small according to a certain screen brightness step length, controlling the screen brightness of the intelligent glasses to be the selected plurality of screen brightness values respectively, and recording the user pupil diameter corresponding to each screen brightness value.

S12: and (3) corresponding the screen brightness values to the pupil diameters one by one, and establishing a mapping relation between the screen brightness values and the pupil diameters.

In the embodiment of the present application, the mapping relationship between the screen brightness value and the pupil diameter may be established by directly corresponding the plurality of screen brightness values to the plurality of pupil diameters one by one, and specifically, the mapping relationship may be expressed as a mapping table, for example, (L1, D1), (L2, D2), (Ln, dn). Wherein, L1, L2, & gt. Ln represents a different screen brightness value, D1, D2, &..and Dn represent pupil diameters of the user in the case of screen brightness L1, L2, &..and Ln, respectively.

Or, a plurality of screen brightness values and a plurality of pupil diameters are linearly fitted, a function or a curve is obtained, and then the corresponding pupil diameters can be determined for any screen brightness value according to the function or the curve.

By obtaining the pupil diameters corresponding to different screen brightness values, the mapping relation between the screen brightness values and the pupil diameters can be automatically and quickly established.

In an optional embodiment, step S11 includes the step of acquiring a plurality of pupil diameters corresponding to a plurality of screen brightness values when the user wears the smart glasses without interference of ambient light, including step S110, specifically including the following steps:

S110: under the condition of no ambient light interference, controlling the screen brightness of the intelligent glasses to gradually increase from dark to light or gradually decrease from light to dark according to a preset screen brightness adjustment step length, and obtaining a plurality of pupil diameters corresponding to a plurality of screen brightness values when a user wears the intelligent glasses.

In the embodiment of the application, after the user wears the intelligent glasses, the user wears the eyeshade, so that the interference of external environment light is minimized. And controlling the screen brightness of the intelligent glasses to gradually increase from dark to bright or gradually decrease from bright to dark according to a preset screen brightness adjustment step length, and recording the pupil diameter of the user corresponding to each screen brightness value until the screen brightness of the intelligent glasses reaches the maximum brightness of eye safety, and stopping recording the pupil diameter of the user.

According to the preset screen brightness adjustment step length, the screen brightness of the intelligent glasses is gradually increased from dark to bright or gradually decreased from bright to dark, so that the screen brightness of the intelligent glasses can be slowly changed, and discomfort brought to a user due to sudden change of the screen brightness is avoided.

In an alternative embodiment, the users include calibrated users and uncalibrated users; the calibrated user is a user who establishes a mapping relation between the screen brightness value and the pupil diameter; the uncalibrated user is a user who does not establish the mapping relation between the screen brightness value and the pupil diameter, and before step S11, the uncalibrated user comprises S111-S112, and the method specifically comprises the following steps:

s111: when a user wears intelligent glasses, iris detection is carried out on the user, and an iris detection result is obtained;

s112: if the iris detection result indicates that the user is not calibrated, under the condition that no ambient light is interfered, a plurality of pupil diameters corresponding to a plurality of screen brightness values are obtained when the user wears the intelligent glasses.

In the embodiment of the application, different pupil diameters of users are different under the same screen brightness. Therefore, for each user, a mapping relationship between the screen brightness value and the pupil diameter needs to be established. Marking the users with the established mapping relation as calibrated users, storing the mapping relation in the memory of the intelligent glasses, and marking the users without the established mapping relation as uncalibrated users.

After the user wears the intelligent glasses, whether the user is a calibrated user needs to be verified, if the user is the calibrated user, the mapping relation between the screen brightness value and the pupil diameter does not need to be established for the user, and the mapping relation corresponding to the user in the memory is directly called. If the user is a calibration user, a mapping relation between the screen brightness value and the pupil diameter needs to be established for the user.

And verifying whether the user is a calibrated user or not, wherein the user identity can be identified according to the iris detection result obtained by iris detection of the user. Or when the user uses the intelligent glasses, the user inputs the user identification, and the user identity is identified according to the user identification.

Optionally, the previously established mapping relationship may not have high accuracy or precision in consideration of improvement of pupil diameter recognition algorithm of the smart glasses or improvement of screen brightness value adjustment sensitivity. Therefore, after verifying that the user is a calibrated user, a calibration interface can be displayed on the display screen of the intelligent glasses to prompt the user whether to need recalibration, and if the user confirms recalibration, the mapping relation between the screen brightness value and the pupil diameter is reestablished for the user.

In an alternative embodiment, if the deviation between the first pupil diameter and the second pupil diameter is not within the preset threshold range in step S30, before the step of adjusting the screen brightness of the smart glasses, step S301 is included, which specifically includes the following steps:

s301: obtaining a slope parameter according to the mapping relation; the slope parameter is used to indicate the relationship of pupil diameter as a function of screen brightness value.

In the embodiment of the application, a preset number of screen brightness values and corresponding pupil diameters can be selected from the mapping table corresponding to the mapping relation, and the preset number of screen brightness values and the corresponding pupil diameters are subjected to linear fitting to obtain slope parameters of the pupil diameters changing along with the screen brightness values. And linear fitting can be performed on all the screen brightness values and the corresponding pupil diameters in the mapping table corresponding to the mapping relation, so as to obtain slope parameters of the pupil diameters along with the change of the screen brightness values.

If the deviation between the first pupil diameter and the second pupil diameter is not within the preset threshold range, the step of adjusting the screen brightness of the intelligent glasses includes steps S31 to S32, specifically as follows:

s31: obtaining a target screen brightness value corresponding to the first pupil diameter according to the slope parameter and the deviation between the first pupil diameter and the second pupil diameter;

S32: and adjusting the screen brightness to a target screen brightness value so that the adjusted screen brightness is in a human eye comfort range.

In the embodiment of the application, since the change of brightness causes the change of the pupil diameter, the change of the pupil diameter also reflects the change of brightness. The slope parameter reflects the change of the pupil diameter with the screen brightness, and it can be approximately understood that the slope parameter may reflect the change of the pupil diameter with the screen brightness and the ambient light brightness. Therefore, the target screen brightness value corresponding to the first pupil diameter can be obtained through the slope parameter and the deviation between the first pupil diameter and the second pupil diameter.

After the target screen brightness value is determined, the current screen brightness of the intelligent glasses can be directly adjusted to the target screen brightness, so that the adjusted screen brightness is in a human eye comfort range, and the efficiency of screen brightness adjustment is improved.

In an alternative embodiment, referring to fig. 2, step S301 includes steps S302 to S303, which are specifically as follows:

s302: under the condition of no ambient light interference, acquiring a plurality of pupil diameters corresponding to a plurality of screen brightness values when a user wears intelligent glasses;

S303: and linearly fitting the screen brightness values and the corresponding pupil diameters to obtain slope parameters of the pupil diameters changing along with the screen brightness values.

The linear fitting is to find a best fit straight line for two or more sets of data by a least square method for processing dependent variables that are in linear relation to independent variables. In the embodiment of the application, the pupil diameter is found to be in a linear change relation with the screen brightness through multiple data collection. Therefore, a plurality of screen brightness values and corresponding pupil diameters can be linearly fitted, and slope parameters of the pupil diameters changing along with the screen brightness values can be automatically and rapidly obtained.

In an alternative embodiment, step S31 includes step S311, which is specifically as follows:

S311: multiplying the deviation between the first pupil diameter and the second pupil diameter by a slope parameter to obtain a product result; and taking the sum of the product result and the first screen brightness value as a target screen brightness value corresponding to the first pupil diameter.

In the embodiment of the application, since the slope parameter reflects the change of the pupil diameter along with the screen brightness, the slope parameter may be the ratio of the screen brightness change value to the pupil diameter change value. The screen brightness variation value can be obtained by multiplying the deviation between the first pupil diameter and the second pupil diameter by the slope parameter. And summing the screen brightness change value with the first screen brightness value to automatically and quickly obtain a target screen brightness value corresponding to the first pupil diameter.

In an alternative embodiment, referring to fig. 3, if the deviation between the first pupil diameter and the second pupil diameter is not within the preset threshold range in step S30, the step of adjusting the screen brightness of the smart glasses includes steps S33 to S36, which are specifically as follows:

S33: if the deviation between the first pupil diameter and the second pupil diameter is not in the preset threshold range, determining the screen brightness adjusting direction of the intelligent glasses according to the first pupil diameter and the second pupil diameter.

In the embodiment of the application, the screen brightness adjusting direction comprises two adjusting directions of adjusting the screen brightness to be higher and adjusting the screen brightness to be lower. And comparing the first pupil diameter with the second pupil diameter, and determining the screen brightness adjusting direction of the intelligent glasses according to the comparison result.

S34: and adjusting the screen brightness of the intelligent glasses according to the preset second screen brightness adjusting step length and the screen brightness adjusting direction.

In the embodiment of the application, the screen brightness of the intelligent glasses is slowly changed according to the preset second screen brightness adjustment step length, so that discomfort brought to a user by screen brightness abrupt change is avoided. Specifically, if the screen brightness adjustment direction is to adjust the screen brightness higher, the screen brightness of one step length is increased on the basis of the current screen brightness, and the adjusted screen brightness is obtained. If the screen brightness adjusting direction is to lower the screen brightness, reducing the screen brightness of one step on the basis of the current screen brightness to obtain the adjusted screen brightness.

S35: after the screen brightness of the intelligent glasses is adjusted each time, whether the deviation between the pupil diameter of the user wearing the intelligent glasses and the pupil diameter corresponding to the adjusted screen brightness value is within a preset threshold value range is judged.

In the embodiment of the application, after screen brightness adjustment of one step is performed each time, the pupil diameter corresponding to the adjusted screen brightness value is determined according to the mapping relation, and the deviation between the pupil diameter when the user wears the intelligent glasses and the pupil diameter corresponding to the adjusted screen brightness value is calculated according to the pupil diameter, acquired by the camera, of the user wearing the intelligent glasses, so that whether the deviation is in a preset threshold range is judged.

S36: if not, the screen brightness adjusting direction of the intelligent glasses is re-determined, and the screen brightness of the intelligent glasses is adjusted according to the preset second screen brightness adjusting step length and the re-determined screen brightness adjusting direction until the adjusted screen brightness is in the human eye comfort range.

In the embodiment of the application, if the deviation is not in the preset threshold range, the screen brightness is required to be adjusted. At this time, since the current comparison result of the pupil diameter corresponding to the adjusted screen brightness value when the user wears the smart glasses may be the same as or opposite to the comparison result before adjusting the screen brightness, it is necessary to re-determine the screen brightness adjustment direction of the smart glasses according to the current comparison result. And then, according to the preset second screen brightness adjustment step length and the redetermined screen brightness adjustment direction, adjusting the screen brightness of the intelligent glasses until the adjusted screen brightness is in a human eye comfort range.

If the deviation is within the preset threshold range, the adjusted screen brightness is within the human eye comfort range, and the screen brightness is not required to be adjusted.

Through the preset second screen brightness adjustment step length and the screen brightness adjustment direction, the screen brightness of the intelligent glasses is adjusted, so that the screen brightness of the intelligent glasses can be changed slowly, and discomfort brought to a user due to abrupt change of the screen brightness is avoided.

In an alternative embodiment, referring to fig. 4, if the deviation between the first pupil diameter and the second pupil diameter is not within the preset threshold range in step S33, the step of determining the screen brightness adjustment direction of the smart glasses according to the first pupil diameter and the second pupil diameter includes steps S331 to S332, which are specifically as follows:

S331: if the deviation between the first pupil diameter and the second pupil diameter is not in the preset threshold range, when the first pupil diameter is larger than the second pupil diameter, the screen brightness adjusting direction of the intelligent glasses is to adjust the screen brightness of the intelligent glasses to be higher;

s332: when the first pupil diameter is smaller than the second pupil diameter, the screen brightness adjusting direction of the intelligent glasses is to lower the screen brightness of the intelligent glasses.

In the embodiment of the application, the pupil diameter of the user is reduced because the brightness of the external environment is larger than the brightness of the screen. The brightness of the external environment is smaller than the brightness of the screen, causing the pupil diameter of the user to become larger. By comparing the first pupil diameter and the second pupil diameter, the adjustment direction of the screen brightness can be automatically and quickly determined.
