Intraoral camera system, tooth identification method, control method, and recording medium

A tooth identification method comprising:

• generating image data by an imaging unit capturing an image of a tooth inside a mouth of a user;
• detecting an orientation of the imaging unit according to output by a multi-axis acceleration sensor and detecting, according to the orientation detected, an area whose image is being captured by the imaging unit from among a plurality of areas inside the mouth, the plurality of areas being determined by dividing a dentition into sections;
• and
• narrowing a plurality of candidates which are combinations of tooth types and tooth positions down to fewer candidates to be used, according to the image data and the area detected, and identifying a type and a position of the tooth shown in the image data, according to the fewer candidates narrowed down and the image data.

A method of controlling an intraoral camera system including one or more processors and a display, the method comprising:

• the following executed by the one or more processors:
• obtaining image data generated by an intraoral camera capturing an image of a tooth inside a mouth of a user;
• detecting, according to an orientation of the intraoral camera, an area whose image is being captured by the intraoral camera from among a plurality of areas inside the mouth, the plurality of areas being determined by dividing a dentition into sections;
• and
• narrowing a plurality of candidates which are combinations of tooth types and tooth positions down to fewer candidates to be used, according to the image data and the area detected, and
• identifying a type and a position of the tooth shown in the image data, according to the fewer candidates narrowed down and the image data, and
• displaying, by the display, information on the type and the position of the tooth.
