摘　　要：针对使用者在刷牙过程中刷牙位置和姿势不规范而导致口腔清洁不彻底的问题,提出了刷牙位姿定位方法。通过监测使用者在刷牙过程中对牙刷握轴运动感知牙刷位姿,并结合牙釉面区域归类算法和刷牙角度检测算法识别出牙釉质面刷拭区域和牙面刷拭夹角来提醒使用者调整刷牙行为。经实验验证,该方法满足对牙釉质面刷拭区域和牙面的刷拭夹角实时监测的要求,能准确检测使用者的刷牙位姿并反馈错误信息,帮助使用者纠正不良刷牙行为,从而提高刷牙质量。Aiming at the problem of incomplete oral cleaning caused by irregular tooth brushing position and posture of the user in the process of tooth brushing,a method for positioning and posture of tooth brushing is proposed.This method senses the position and posture of the toothbrush by monitoring the user’s movement of the toothbrush grip shaft during the brushing process,and combines the enamel area classification algorithm and the tooth brushing angle detection algorithm to identify the enamel surface brushing area and the tooth brushing angle,so as to remind users to adjust their brushing behavior.It is experimentally verified that this method meets the requirements of real-time monitoring of the brushing angle between the enamel surface brushing area and the tooth surface.It can timely detect the user’s tooth brushing posture and feedback error information to help users correct their bad brushing behavior.
