A toothbrushing quality detection system and method based on a double-unit asymmetrical sound field

Abstract

The invention discloses a tooth brushing quality detection system and a detection method based on a double-unit asymmetrical sound field, and relates to the technical field of sensors, machine learning and artificial intelligence. The system comprises a sound field acquisition module, a tooth brushing data calibration module, a statistical characteristic extraction module, a module training moduleand a real-time tooth brushing detection module. The detection method comprises the following steps: acquiring standard tooth brushing audio data, and calibrating the audio data; implementing statistical characteristic extraction on the calibrated audio data, and constructing a dual-channel audio database of a standard tooth brushing mode; constructing a tooth brushing detection model; and acquiring audio data in a tooth brushing process of a user in real time, implementing statistical characteristic extraction, and outputting classification results via an optimal model, wherein the classifying results are eighteen detection events. According to the tooth brushing quality detection system and the method provided by the invention, the stability of data is guaranteed, and the clearness andsignificance of the data are guaranteed; a calculated amount can be effectively reduced; a medium and long-term tooth brushing habit log of the user can be constructed; and a goal of real-time tooth brushing quality and long-term user's oral hygiene tracking can be achieved.

Description

technical field [0001] The invention relates to the technical fields of sensors, machine learning and artificial intelligence, in particular to a toothbrushing quality detection system and method based on a double-unit asymmetrical sound field. Background technique [0002] Brushing teeth is an important way to protect dental health, and the quality of tooth brushing has a significant impact on dental health. However, with the continuous development of society, the pace of life of modern urban residents continues to accelerate, especially in metropolises where life is stressful and full of competition. , different degrees of ignoring their own health status, and daily dental care is one of them. In fact, daily brushing may be the most effective way to keep your mouth healthy, considering the frequent occurrence of oral health problems and the high cost of dental care that comes with it. [0003] At the same time, the shortage of medical resources in cities and the high cos...

Problems solved by technology

[0004] Although developing good brushing habits can help improve oral hygiene to a certain extent, how to ensure the quality of each brushing is still difficult to achieve

Although some high-end electric toothbrushes evaluate the user's brushing quality through built-in sensors and software, due to their high price, it is difficult for low-end electric toothbrushes and the general population to afford this cost
