When the matching degree of the characteristics of any preset authentication information and the characteristics of the authentication information of the current user is greater than a preset threshold value, the authentication information of the current user is matched with the preset authentication information, and the method can be realized in the following way: when comparing the plurality of pieces of preset iris information with the iris information of the current user, when the matching degree between the iris information of the current user and one of the pieces of preset iris information is greater than or equal to a preset threshold (for example, the preset threshold may be 99%, 99.5%, 98%, or the like), it is determined that the iris information of the current user matches with the preset iris. And when the matching degree of the iris information of the current user and all the preset iris information is smaller than a preset threshold value, the current user authentication fails.
Further, as shown in fig. 7, the method for controlling glasses according to the embodiment of the present disclosure may further include:
step S550, when the authentication information of the current user is not matched with the preset authentication information, the interpupillary distance of the current user is obtained;
step S560, storing the authentication information of the current user and the interpupillary distance of the current user as preset authentication information and a preset interpupillary distance.
In step S550, when the authentication information of the current user does not match the preset authentication information, the interpupillary distance of the current user may be acquired.
The obtaining of the pupil distance of the current user may be calculating the pupil distance of the two eyes of the user by obtaining images of the two eyes of the user and by means of binocular vision or multi-ocular vision; or the user can be prompted to input the pupil distance, and the pupil distance input by the user is used as the current pupil distance of the user; or the user can adjust the pupil distance adjusting assembly 130 to adjust the pupil distance of the glasses to match the pupil distance of the user, and the pupil distance at the moment is recorded and stored as the pupil distance of the user.
In step S560, the authentication information of the current user and the pupil distance of the current user may be stored as the preset authentication information and the preset pupil distance.
Wherein the authentication information of the current user and the interpupillary distance of the current user may be stored in the storage unit 155. In the storage unit 155, there is a corresponding relationship between the authentication information of the current user and the pupil distance of the current user. When the authentication information of the current user and the pupil distance of the current user are used as the preset authentication information and the preset pupil distance, the authentication information and the preset pupil distance correspond to each other, so that the current user completes authentication and subsequent use is facilitated.
Further, as shown in fig. 8, the glasses control method provided in the embodiment of the present disclosure further includes:
and step S570, adjusting the interpupillary distance of the glasses according to the interpupillary distance of the current user so as to enable the interpupillary distance of the glasses to be consistent with the interpupillary distance of the current user.
When the current user uses the glasses for the first time, the pupil distance of the current user is not stored in the glasses, so that the pupil distance of the glasses is consistent with the pupil distance of the current user, and the pupil distance of the glasses can be adjusted through the pupil distance adjusting assembly 130.
Further, in order to avoid the damage to the eyes caused by the long-time use of the glasses by the user, as shown in fig. 9, the method for controlling the glasses provided by the embodiment of the present disclosure may further include:
step S910, acquiring an eye state signal of a user;
step S920, generating a user reminding message in response to the eye state signal.
In step S910, a glasses status signal of the user may be obtained, wherein the glasses status signal of the user may be obtained by obtaining an eye image of the user. The eye state signal of the user may include a blinking frequency of the user, a time for which the eyes of the user continue to use the glasses, and the like. The eye state signal of the user can be acquired by a camera or the like. For example, the camera in the iris acquisition module can be shared to acquire the glasses leg state signal of the user.
In step S920, a user alert message may be generated in response to the eye state signal. When the glasses state signal of the user is out of the preset state, the control module 150 generates user reminding information, and the user reminding information is used for reminding the user to have a rest. For example, when the time length (the time that the iris acquisition module continuously acquires the iris) of the user using the glasses exceeds the specified time, generating user reminding information; or when the blinking frequency of the user exceeds the preset frequency, generating user reminding information.
Further, when the glasses further include the pressure detection assembly 180 and the temple adjustment assembly 190, as shown in fig. 10, the method for controlling the glasses according to the embodiment of the present disclosure may further include:
step S1010, acquiring pressure values of the first glasses leg and/or the second glasses leg and the head of the user;
and step S1020, when the pressure values of the first glasses leg and/or the second glasses leg and the head of the user are within a preset pressure range, adjusting the distance between the first glasses leg and the first lens and the distance between the second glasses leg and the second lens.
In step S1010, pressure values of the first temple 160 and/or the second temple 170 and the user' S head may be acquired.
Wherein the pressure values of the first temple 160 and/or the second temple 170 and the user's head may be detected by the pressure sensing assembly. Since the first and second temples 160 and 170 are located at both sides of the head when in use, the pressure of the first temples 160 and the head of the user can be obtained when the pressure of the temples and the head of the user is obtained; or to acquire pressure of the second temple 170 and the user's head; or may simultaneously acquire the pressure of the first and second temples 160 and 170 and the user's head.
In step S1020, when the pressure values of the first and/or second temples 160 and 170 and the user' S head are within the preset pressure range, the distance between the first temples 160 and the first lenses 110 and the distance between the second temples 170 and the second lenses 120 may be adjusted.
When adjusting the distance between the temple and the spectacle lens, it may be that when detecting that the pressure between the temple and the head of the user is greater than a first preset pressure threshold, the temple is adjusted away from the lens (the first temple 160 is away from the first lens 110, and the second temple 170 is away from the second lens 120); and when the pressure between the glasses legs and the head of the user is detected to be less than a second preset pressure threshold value, adjusting the glasses legs to be close to the lenses (the first glasses legs 160 are close to the first lenses 110, and the second glasses legs 170 are close to the second lenses 120).
Further, in order to avoid that the glasses power supply 220 is still in the on state when the glasses are in the non-use state, for example, the user forgets to turn off the glasses after use is finished, as shown in fig. 11, the method for controlling the glasses according to the embodiment of the present disclosure further includes:
and step 580, controlling the glasses to be powered off when the iris of the user is not detected within the preset time.
The iris collecting module detects the using state of the glasses and generates a glasses using state signal, the control module 150 receives the glasses using state signal and transmits a power supply 220 control signal to the control terminal of the power switch 230 according to the glasses using state signal, and the power switch 230 is turned off in response to the power supply 220 control signal.
When the iris acquisition module (camera) does not acquire the iris image after exceeding the preset time, the glasses are considered to be in a non-use state, the control module 150 outputs a power supply 220 control signal, and the switching element is turned off in response to the power supply 220 control signal. The problem that the user does not turn off the power supply 220 when finishing using the glasses, which wastes energy is avoided.
According to the control method of the glasses provided by the embodiment of the disclosure, by acquiring the authentication information of the current user, when the authentication information of the current user is matched with the preset authentication information, the preset interpupillary distance corresponding to the preset authentication information is acquired, and the interpupillary distance adjusting component 130 is controlled to adjust the relative positions of the first lens 110 and the second lens 120 according to the preset interpupillary distance, so that the glasses can be adjusted according to the interpupillary distances of different users, and the universality of the glasses on different users is improved.
