Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
Bathroom mirrors with lamps are widely used in bathrooms or toilet places, and the lamps arranged on the existing bathroom mirrors are used for illuminating users, lighting and providing atmosphere light, but the lamps of the bathroom mirrors generally have no intelligent adjusting function except lighting.
However, the intelligent mirror in the prior art is rarely related to the emotion of the user, so that it is necessary to provide an LED lamp mirror capable of taking care of the emotion of the user to solve the increasing emotion management requirement.
Example 1
In order to solve the above-mentioned problem, this embodiment discloses an LED mirror cabinet, its structure includes:
A lamp mirror body;
the face detection module is used for acquiring a current face image of a user and acquiring key positioning points of the face of the current user;
the LED lamp strip is used for displaying different colors and brightness;
And the processing module is used for processing the face image acquired by the face detection module, judging the current emotion state of the user, and quantifying the face image to adjust the color tone of the LED lamp strip.
In this embodiment, the processing module uses facial recognition techniques in conjunction with machine learning announcements to analyze the acquired facial images to infer the emotional state of the user. It should be noted that the structures and principles of the face detection module and the processing module in this embodiment are all in the prior art, and are not described herein.
Further, the embodiment also provides an emotion adaptation method, which includes the following steps:
S100, a face detection module acquires a facial image of a face, acquires the key point variation of the facial expression in unit time, and calculates an emotion index E according to a corresponding weight coefficient w Old one ;
S200, calculating a target light effect state L Target object through a target light formula according to the emotion index E, and controlling the LED lamp strip to gradually display through the target light effect state L Target object ;
S300, calculating a user feedback index K;
S400, calculating a new weight coefficient w New type , replacing the value of the weight coefficient w New type with the value of the weight coefficient w Old one in the step S100, and executing the steps S100 to S400 in a reciprocating manner.
Through the circulation process, the LED mirror cabinet can adapt to the emotion change of the user in real time, more personalized user experience is provided, and the dynamic updating mechanism ensures that the system can be adjusted according to the real-time emotion and feedback of the user.
Further, in step S100, the calculation formula of the emotion index E is:
E＝w1·f1+w2·f2+…+wn·fn
Wherein w n is the nth facial expression, and f n is the weight coefficient corresponding to the nth facial expression.
Further, the calculation formula of f n is:
Where x n,yn is the coordinates of the nth key point of the current expression, and x n0,yn0 is the coordinates of the nth key point of the reference expression.
It should be noted that, the key points in this embodiment may be positions such as eyebrows, eyes, nose, and mouth; and comparing the difference between the key point of the current expression of the user and the key point of the reference expression (such as the neutral expression), and calculating the variation of each key point. Since facial features and expression habits of each person are different, it is necessary to perform standardization processing on the amount of change in key points so that it is not affected by individual differences.
Further, in step S200, the calculation formula of L Target object is:
L Target object (E)＝(C(E),I(E))
where L Target object is the target light state calculated from the user emotion index E, C (E) is the color function, and I (E) is the luminance function.
Further, the calculation formula of the color function is:
The calculation formula of the brightness function is:
Wherein E max is the maximum possible value of the emotion index, and I max is the maximum brightness value of the LED light bar.
Assume that the emotion index E ranges from 0 to 100, where 0 represents a very negative emotion and 100 represents a very positive emotion. Wherein, the color function C (E) and the luminance function I (E) are defined as:
If the user's emotion index E is 50, representing a neutral emotional state, then the target LED light state L Target object (E) is:
L Target object (E)＝((127.5,127.5,0),0.55·Imax)
the calculation formula for gradually changing display of the LED light bar is as follows:
L New type (t)＝L Old one +(L Target object -L Old one )·(1-e-βt)
where L New type (t) is the LED light state at time t, L Old one is the initial LED light state, β is a positive constant, and t is the time from the onset of the fade to the present.
Let L Old one = (100,100,100) denote that the LED light is initially neutral white with a brightness of 100; l Target object = (255, 0), indicating that the target LED light is red and the brightness is 255; beta=0.1, representing the fade rate.
If one wants to calculate L New type (t) in t=0 to t=5 seconds, we can get the time t=1:
L New type (1)＝(100,100,100)+((255,0,0)-(100,100,100))·(1-e-0.1·1)
L New type (1)≈(114.725,90.5,90.5)
this means that after 1 second, the LED light will be near neutral white but reddish. Over time, this value will continue to approach L New type (t) until the target state is eventually reached. This process creates a smooth transition effect that avoids the discomfort of the user from abrupt changes in light.
Further, in step S300, the calculation formula of the user feedback index K is:
K＝E+k·U
Where k is the adjustment coefficient and U is the user satisfaction score.
Further, the calculation formula of the user satisfaction score is:
U＝a·Fd+b·Ff+c·Ft
Where F d is a user input satisfaction score, F f is a function of user frequency of use, F t is a function of user dwell time, a, b, c are weighting coefficients.
Further, the calculation formula of F f is:
Wherein, N is the times of using the mirror cabinet by the user in a certain time T, and the frequency of using the LED mirror cabinet by the user can reflect the preference degree of the user to the product;
The calculation formula of F t is:
Wherein M is the total number of times the user uses the mirror cabinet, t i is the stay time of the user using the mirror cabinet each time, and the stay time of the user before the LED mirror cabinet can indirectly reflect the satisfaction degree of the user on the current setting.
Further, in step S400, the calculation formula of the weight coefficient w New type is:
w New type ＝w Old one +α·U·fi
Wherein f i is a normalized value of the variation of the ith facial key point in the current emotion recognition process, and alpha is a positive number.
In this way, the updating of the weight coefficient directly reflects the satisfaction score of the user, so that the emotion recognition algorithm can be better adapted to the feedback of the user. Over time, the system will learn and optimize the weight coefficients through the continuous feedback of the user, thereby improving the overall user experience.
In summary, according to the LED bathroom mirror with the function of adapting to the emotion of the user, based on the face detection module, the LED light bar and the processing module, the face image of the face is detected, the current emotion is judged according to the recognized facial expression, and the LED light bar emits corresponding light to adapt to the current emotion of the user, so that the emotion can be stimulated or relaxed in subconscious effect; in addition, the invention can also combine the feedback of the user to change the adjustment strategy of the LED lamp group, so that the invention can better adapt to the personalized requirements of the user and solve the increasing emotion management requirements.
In addition, the LED bathroom mirror of the embodiment can be further provided with a music playing module and an aromatherapy module, wherein the music playing module is arranged in the lamp mirror body, and a loudspeaker connected with the music playing module faces the outside from the side edge of the lamp mirror body; the aromatherapy module is arranged at the bottom or at the side of the lamp mirror body.
When the LED lamp strip is used, pre-stored music is classified according to categories, after the emotion index E of a user is calculated according to the mode, the corresponding categories of music are played besides the brightness of the LED lamp strip, for example, when the user is happy, the user plays light and quick music; when the emotion of the user falls, determining to play the excited or relaxed music according to the feedback index K of the user; when the user is tired, the user plays relaxed music and the like, and the two dimensions of sound and light are combined to adjust according to the emotion of the user, so that the bad emotion of the user is released as soon as possible, and the active emotion is kept.
The fragrance module is mainly used for adjusting the concentration/type of the released fragrance according to the emotion index of the user, so that the user experiences different fragrances in a concentration matching mode, and the user experience of the embodiment is improved.
Example 2
The embodiment provides a mirror cabinet, it includes the cabinet body and the activity sets up in the cabinet door of the cabinet body, and the front end of this cabinet door is equipped with the LED bathroom mirror of embodiment 1.
Therefore, the LED bathroom mirror with the user emotion adaptation function of the present embodiment is based on the face detection module, the LED light bar and the processing module, and by detecting the face image of the face, the current emotion is judged according to the recognized facial expression, and the LED light bar emits corresponding light to adapt to the current user emotion, so that the emotion can be stimulated or relaxed in subconscious effect; in addition, the invention can also combine the feedback of the user to change the adjustment strategy of the LED lamp group, so that the invention can better adapt to the personalized requirements of the user and solve the increasing emotion management requirements.
Under this embodiment, the music playing module and the aromatherapy module are both arranged on the cabinet body, so that the cabinet door is simpler in structure and the weight of the cabinet door is reduced.
