In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present invention in its various embodiments. However, the technical solution claimed in the present invention can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a tooth brushing evaluation method, which can be applied to tooth brushing evaluation terminal equipment, including but not limited to computing equipment such as smart phones, notebooks, tablet computers, PCs and cloud servers. The method comprises the following steps: the method comprises the steps of acquiring tooth brushing data detected by a data detection device in an intelligent toothbrush of a user in real time; analyzing and obtaining the attitude data of each tooth brushing position according to the tooth brushing data; determining a tooth brushing surface corresponding to each tooth brushing position according to the attitude data and the corresponding relation between the attitude data and the tooth brushing surface; wherein the brushing surface is the brush head or the brushing range corresponding to 2 to 3 teeth; and obtaining the brushing evaluation result according to the brushing data of each brushing surface. The embodiment of the invention can identify the brushing position corresponding to the brush head or 2-3 teeth, and can accurately identify a smaller brushing position compared with the prior art, so that the brushing evaluation result can better reflect the real brushing condition of the user, and the user is helped to improve the brushing action and habit.
The method of the present embodiment will be described in detail with reference to fig. 1. The method includes steps 101 to 104.
Step 101: and acquiring the tooth brushing data detected by the data detection device in the intelligent toothbrush of the user in real time.
Specifically, the intelligent toothbrush may be provided with an attitude sensor such as an acceleration sensor and a three-axis gyroscope. The three-axis acceleration sensor can detect the acceleration of the intelligent toothbrush in the X, Y, Z triaxial direction, and the three-axis gyroscope can detect the angular speed of the intelligent toothbrush in the X, Y, Z triaxial direction. The intelligent toothbrush can also be provided with a pressure sensor which can be used for detecting the pressure of each tooth brushing position when the intelligent toothbrush performs tooth brushing action. However, without being limited thereto, other types of data detection devices may also be provided in the intelligent toothbrush.
Step 102: and analyzing according to the tooth brushing data to obtain the posture data of each tooth brushing position.
In this embodiment, the three-axis gyroscope can directly output three-axis attitude angles. The acceleration sensor can detect the displacement direction, speed, distance and the like of the intelligent toothbrush. The posture change trend of the intelligent toothbrush can be accurately judged by fusing the three-axis acceleration and the three-axis angular velocity.
The calculation of the three-axis acceleration and the three-axis angular velocity is described as follows:
the three-axis acceleration and three-axis gyroscope raw output data patterns are as follows:
Acc：-4332 9828 10888 Gyro:-362 -87 60
the original output data needs to be converted into a triaxial acceleration value and a triaxial angular velocity according to a triaxial acceleration and a precision setting value of a triaxial gyroscope. In the embodiment of the invention, the precision of the triaxial gyroscope is 16.4LSB (least significant Bit)/(° s). Angular velocity X is the raw output data/16.4 (°/s) in degrees per second. The sensitivity of the triaxial acceleration is set to 2048, and the value read from the triaxial acceleration sensor is divided by 2048, which can be converted to a triaxial acceleration value. For example, if the number read from the accelerometer is 1000, then the corresponding acceleration data is 1000/2048 ═ 0.49 g. g is the unit of acceleration and the acceleration of gravity is defined as 1g, equal to 9.8 meters per square second. In practical application, the data sampling frequency of the three-axis acceleration sensor and the three-axis gyroscope is set to 1000HZ, so that accurate three-axis acceleration and three-axis angular velocity can be obtained.
In the embodiment of the invention, the pitching angle, the rolling angle and the course angle of each tooth brushing position can be obtained according to the fusion of the three-axis acceleration output by the three-axis acceleration sensor and the three-axis angular velocity output by the three-axis gyroscope. Specifically, after acquiring the three-axis acceleration and the three-axis angular velocity, kalman filtering processing is performed on the three-axis acceleration and the three-axis angular velocity, and attitude fusion processing is performed on the three-axis acceleration and the three-axis angular velocity after filtering processing, so that three attitude data of the intelligent toothbrush, such as a Roll angle Roll, a Pitch angle Pitch, a course angle Yaw and the like, are obtained.
It can be understood that, in the intelligent toothbrush, a triaxial geomagnetic sensor can be further arranged for correcting data drift of the triaxial acceleration sensor and the triaxial gyroscope, so that the accuracy of data detection can be improved.
Step 103: and determining the tooth brushing surface corresponding to each tooth brushing position according to the attitude data and the corresponding relation between the attitude data and the tooth brushing surface. Wherein, the brushing surface is the brush head or the brushing range corresponding to 2 to 3 teeth.
In the embodiment of the invention, the brushing head of the intelligent toothbrush or the brushing position corresponding to 2-3 teeth can be identified and obtained according to the three posture data obtained in the step 102. Taking 20 deciduous teeth of the child as an example, as shown in fig. 2, the teeth in the mouth of the child can be divided into 24 brushing surfaces, so as to establish a corresponding relationship between the three posture data and the 24 brushing surfaces. Wherein, the number of the upper teeth is 10, the outer side surfaces of every two upper teeth are divided into one tooth brushing surface (A, B, C, D, E) from left to right, the inner side surfaces of every two teeth are also divided into one tooth brushing surface (K, L, M, N, O), and the chewing surfaces of the three teeth on the left inner side and the right inner side of the upper jaw are respectively divided into one tooth brushing surface (U, V). Similarly, 10 teeth of the mandibular teeth are divided into 12 brushing surfaces (J, I, H, G, F, P, Q, R, S, T, W, X).
In this embodiment, when the intelligent toothbrush is placed horizontally, the bristles face the incisors in the oral cavity of the human body, the central point of the brush head is the original point, the direction of the bristles is the positive direction of the X axis, the direction of the brush handle is the positive direction of the Y axis, and the opposite direction of the geocentric direction is the positive direction of the Z axis, so as to establish a reference coordinate system. Wherein, the corresponding relation between the posture data and the tooth brushing surface is as follows:
posture angle range of 5 brushing tooth surfaces of the lateral surface of the upper jaw:
the A area has 55 degrees < YAW < 85 degrees-45 degrees < Pitch < 45 degrees-45 degrees < Roll < 45 degrees
The B zone has 25 degrees < YAW < 55 degrees-45 degrees < Pitch < 45 degrees-45 degrees < Roll < 45 degrees
The C region is-25 degrees < YAW is less than or equal to 25 degrees < Pitch is less than or equal to 45 degrees < Roll is less than or equal to 45 degrees
D zone 125 degree < YAW ≤ 155 degree-45 degree < Pitch ≤ 45 degree-45 degree < Roll ≤ 45 degree
E zone 95 degrees < YAW < 125 degrees-45 degrees < Pitch < 45 degrees-45 degrees < Roll < 45 degrees
The posture angle ranges of the 5 brushing surfaces J, I, H, G, F on the lateral surface of the mandibular teeth correspond to the posture angle ranges of the 5 brushing surfaces A, B, C, D, E on the lateral surface of the maxillary teeth, respectively.
Posture angle range of 5 brushing tooth surfaces of the inner side surface of the upper jaw:
k zone 55 degrees < YAW < 85 degrees-45 degrees < Pitch < 45 degrees < 135 degrees < Roll < 225 degrees
L zone 25 degree < YAW ≤ 55 degree-45 degree < Pitch ≤ 45 degree < Roll ≤ 225 degree
M zone-25 degrees < YAW < 25 degrees < 45 degrees < Pitch < 45 degrees < 135 degrees < Roll < 225 degrees
The N region is 125 degrees < YAW < 155 degrees-45 degrees < Pitch < 45 degrees < 135 degrees < Roll < 225 degrees
The O region is 95 degrees < YAW < 125 degrees-45 degrees < Pitch < 45 degrees < 135 degrees < Roll < 225 degrees
The posture angle ranges of the 5 brushing surfaces P, Q, R, S, T on the inner side surface of the lower jaw teeth are respectively corresponding to the posture angle ranges of the 5 brushing surfaces K, L, M, N, O on the inner side surface of the upper jaw teeth.
Posture angle range of two chewing surfaces of upper teeth:
u area 45 degrees < YAW < 85 degrees-45 degrees < Pitch < 45 degrees < Roll < 135 degrees
V zone 95 degree < YAW ≤ 135 degree-45 degree < Pitch ≤ 45 degree < Roll ≤ 135 degree
The posture angle ranges of the two chewing surfaces W, X of the mandibular teeth correspond to the posture angle ranges of the two chewing surfaces U, V of the maxillary teeth, respectively.
As shown in FIG. 3, 32 adult teeth may be divided into 28 brushing surfaces. Similar to the division manner of the 24 brushing surfaces of the children, the proper posture angle ranges can be correspondingly set for the 28 brushing surfaces respectively. According to the embodiment of the invention, the corresponding relation between the corresponding posture data and the tooth brushing surface is respectively established for the children and the adults, so that the evaluation of the tooth brushing result is more targeted.
Step 104: and obtaining the brushing evaluation result according to the brushing data of each brushing surface.
Specifically, the brushing data of each brushing surface may include a brushing pressure value, a brushing time period, and the like of each brushing surface, but is not limited thereto. The brushing effect can be scored according to the brushing data of each brushing surface and used as the brushing evaluation result of the current brushing. After the tooth brushing is finished, tooth brushing data can be displayed to a user in the forms of figures, characters, colors and the like by combining with the tooth model, so that the user can intuitively know the tooth brushing condition.
Compared with the prior art, the embodiment obtains the tooth brushing surface corresponding to each tooth brushing position by analyzing the tooth brushing data detected by the data detection device in the intelligent toothbrush, and obtains the tooth brushing evaluation result according to the tooth brushing data of each tooth brushing surface, wherein each tooth brushing surface corresponds to the brush head or the tooth area of 2-3 teeth. Therefore, the embodiment of the invention can reflect the tooth brushing condition more truly and is helpful for the user to better improve the tooth brushing action and habit. In the embodiment of the present invention, the teeth of the adult are divided into 28 brushing surfaces and the teeth of the child are divided into 24 brushing surfaces, so that the brushing evaluation results for the adult and the child can be obtained.
The second embodiment of the invention relates to a tooth brushing evaluation method, which is an improvement on the basis of the first embodiment, and is mainly characterized in that in the second embodiment, the tooth brushing effect of each user is evaluated according to the corresponding relation between the tooth brushing data and the tooth brushing effect, so that the tooth brushing evaluation method adopting unified standards by all users in the prior art is broken, and the tooth brushing action and habit of the users can be standardized according to the personalized tooth brushing mode of the users.
As shown in fig. 4, the tooth brushing evaluation method of the present embodiment includes steps 401 to 404. Steps 401 to 403 correspond to steps 101 to 103, respectively, and are not described herein again.
Step 404: the brushing evaluation results are obtained according to the brushing data of each brushing surface and the standard brushing data of the user.
The standard tooth brushing data of the user refers to the tooth brushing data which is personalized and achieves better tooth brushing effect for the user. As shown in FIG. 5, obtaining standard brushing data for a user includes steps 501-503.
Step 501: and acquiring the tooth brushing data of the user meeting the preset conditions.
Step 502: and acquiring the tooth brushing effect corresponding to the tooth brushing data meeting the preset conditions.
The preset condition is, for example, that the brushing time corresponding to the brushing data is greater than or equal to a preset number, and the preset number is, for example, 14, but is not limited thereto. The personalized tooth brushing action habits of the user can be better analyzed through the tooth brushing data for a period of time, and the correspondingly obtained tooth brushing effect has higher evaluation value.
As shown in fig. 6, obtaining the tooth brushing effect corresponding to the tooth brushing data satisfying the preset condition includes:
Step 602: and acquiring a second tooth image of each tooth brushing surface of the user after the intelligent toothbrush generates tooth brushing data meeting preset conditions.
Step 603: a brushing effect of the user is determined from the first dental image and the second dental image.
Wherein the first dental image and the second dental image comprise dental images of respective brushing surfaces of the user. The first tooth image and the second tooth image can be acquired through an intelligent toothbrush provided with an image acquisition device, and can also be acquired through an independent image acquisition device. The first tooth image and the second tooth image are respectively tooth images of each brushing surface of the oral cavity of a human body obtained before and after brushing teeth for a preset number of times. The first tooth image and the second tooth image are analyzed to obtain the variation range of the cleanliness of each brushing surface, such as the area of dirt on the tooth surface, the color of the tooth surface and the like. The first tooth cleanliness and the second tooth cleanliness of each brushing surface can be obtained respectively aiming at the first tooth image and the second tooth image, and the difference between the second tooth cleanliness and the first tooth cleanliness of each brushing surface is taken as the cleanliness change amplitude of each brushing surface.
Step 503: and taking the tooth brushing data corresponding to the tooth brushing effect with the tooth brushing cleanliness change amplitude larger than the preset threshold value as standard tooth brushing data of the user.
Wherein the preset threshold of the cleanliness of each tooth brushing surface can be determined according to actual experience. The larger the change amplitude of the tooth brushing cleanliness is, the better the tooth brushing effect is, otherwise, the poorer the tooth brushing effect is. And extracting the tooth brushing data corresponding to the tooth brushing effect of which the tooth brushing cleanliness change amplitude is larger than a preset threshold value from the tooth brushing surface as the standard tooth brushing data of the tooth brushing surface of the user. It is understood that when the variation range of the brushing cleanliness of a certain brushing surface or all brushing surfaces of the user is less than or equal to the preset threshold, steps 501 to 503 can be executed again to obtain the standard brushing data of each brushing surface. Wherein, in executing step 501, the user can be prompted to brush teeth according to the correct brushing mode suggested by the authority expert, such as Bass brushing mode.
It should be noted that the standard tooth brushing data may include tooth brushing time, tooth brushing pressure value, posture data of the intelligent toothbrush, and motion trajectory of the tooth brushing surface. Because the standard tooth brushing data of the user in the embodiment is from the historical tooth brushing actions of the user, the tooth brushing actions can be more conveniently and firmly mastered by the user through subsequent consolidation training.
In one example, the tooth brushing evaluation method of the present embodiment may further include: and guiding the user to perform brushing actions according to the brushing data of each brushing surface of the user and the standard brushing data of the user, which are acquired in real time. Specifically, if the tooth brushing data of each tooth brushing surface of the user deviates from the standard tooth brushing data of the user, the intelligent toothbrush is controlled to pause, and when the real-time tooth brushing data of the tooth brushing surface is matched with the standard tooth brushing data, the intelligent toothbrush is controlled to continue tooth brushing. The intelligent toothbrush is controlled to pause, so that damage to the surfaces of teeth or gums caused by poor tooth brushing modes such as powerful tooth brushing or transverse brushing can be prevented, a user can know and avoid wrong tooth brushing actions, and the user can be reminded to rapidly adjust the tooth brushing actions to continue tooth brushing.
Compared with the prior art, the embodiment obtains the tooth brushing surface corresponding to each tooth brushing position by analyzing the tooth brushing data detected by the data detection device in the intelligent toothbrush, and obtains the tooth brushing evaluation result according to the tooth brushing data of each tooth brushing surface, wherein each tooth brushing surface corresponds to a tooth area of a brush head or a smaller number of teeth.
