Abstract

The invention discloses an intelligent electric toothbrush and a toothbrush space attitude acquisition system and method. The method comprises: establishing a uniform space three-dimensional coordinate system on the electric toothbrush and a human face; establishing a datum projection plane of the human face, carrying out calibration on a human body tooth orientation on the datum projection plane;projecting the human face onto the datum projection plane to acquire a human face projection; determining a space initial position of the toothbrush; projecting the space initial position of the toothbrush onto the datum projection plane to acquire a toothbrush projection; calculating relative positions of the human face projection and the toothbrush projection on the datum projection plane, andacquiring initial position data of the toothbrush relative to the human body tooth orientation; after a toothbrush position is changed, calculating a projection of the changed toothbrush position on the datum projection plane; calculating relative positions of the human face projection and the toothbrush projection on the datum projection plane. According to the invention, datamation and visualization of a toothbrush behavior are implemented, toothbrush attitude data and real-time data are accurately acquired.

Description

technical field [0001] The invention relates to the technical field of intelligent toothbrushes, in particular to an intelligent electric toothbrush, a system and a method for acquiring the spatial attitude of the toothbrush. Background technique [0002] Since the 21st century, smart devices have gradually entered people's lives. These high-tech elements are not limited to mobile phones and tablet computers. Various smart products emerge in an endless stream. The improvement of various APPs greatly simplifies everyone's life. Smartphones have become an inseparable part of everyone's life. With the advancement of society, many people pay more and more attention to their health. Due to the fast pace of urban life and bad living habits, people often ignore brushing their teeth because of laziness. As a result, the oral cavity and teeth are not clean, causing many oral diseases. [0003] The smart electric toothbrush is a new type of high-tech toothbrush that can analyze the ...
