Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] A tooth brushing guidance system based on a sensor-based tooth area identification algorithm, which includes step 1: collecting sensor data; step 2: detecting and identifying the tooth area; step 3: establishing a 3D tooth model, rendering the tooth model according to the calculated coverage ratio and exhibit;

[0028] Step 1: Collect sensor data:

[0029] 1.1: Abstract the acceleration three-axis data of the gyroscope sensor into spheres, and define a data structure Sphere, which contains the fields of the x, y, and z axes of the sphere, and the square of the radius of the sphere, Squared_Radius.

[0030] 1.2: Divide the tooth area into 16 areas.

[0031] 1.3: Use an electric toothbrush to fix and brush one of the tooth areas, and at the same time collect the three-axis acceleration data acceleration_x, acceleration_y, acceleration_z of the gyro sensor and tr...

Abstract

The invention discloses a tooth brushing guide system based on a tooth area recognition algorithm of a sensor. The tooth brushing guide system comprises the following steps: step 1, collecting sensor data; step 2, tooth area detection and identification; 3, establishing a 3d tooth model, and rendering and displaying the tooth model according to the calculated coverage rate; tooth area matching is carried out on toothbrush sensor data of a user through the tooth area matching module, all tooth brushing actions can be accurately tracked and analyzed for dozens of times per second, the user can be helped to control tooth brushing time, efficiency is improved, real-time feedback is obtained, oral care is thoroughly improved through data and technologies, and the user experience is improved. And diseases such as tooth decay and periodontitis can be prevented. And the user can be more intuitively guided to correctly brush teeth through 3d tooth model display.

Description

【Technical field】 [0001] The invention relates to a tooth brushing guidance system based on a sensor-based tooth region identification algorithm. 【Background technique】 [0002] In our daily lives, brushing our teeth is an instinctive task that many people do without realizing the costly impact poor dental hygiene can have on our health. [0003] But there is currently no way to guide us to brushing healthily and effectively, so there is a great need for one that helps us control brushing time, improve efficiency, get real-time feedback, use data and technology to revolutionize oral care, and eradicate tooth decay and periodontitis. and other tooth brushing guidance systems that prevent diseases. [Content of the invention] [0004] The object of the present invention is to overcome the deficiencies of the prior art, to provide a method that can help users to control the brushing time, improve efficiency, obtain real-time feedback, use data and technology to completely tra...
