Three-dimensional tooth image display apparatus and method, and method for training three-dimensional tooth image display apparatus

A three-dimensional tooth image display method comprising:

• dividing a boundary of each object in a dental cross-section image generated by dividing an input three-dimensional dental image in an axial direction;
• recognizing a tooth area among objects in the dental cross-sectional image and detecting a tooth number of each tooth belonging to the tooth area;
• and
• generating a three-dimensional image of each tooth on the basis of the obtained boundary of each object in each dental cross-sectional image and the obtained tooth number of each tooth,
• wherein the three-dimensional image of each tooth has a different display method according to the tooth number.

A method for training a three-dimensional tooth image display apparatus, comprising:

• training a tooth division neural network to divide a boundary of each object in a dental cross-section image generated by dividing an input three-dimensional dental image in an axial direction;
• training a tooth detection neural network to recognize a tooth area among objects in the dental cross-sectional image and detect a tooth number of each tooth belonging to the tooth area;
• and
• training a tooth image obtainment neural network to generate a three-dimensional image of each tooth on the basis of the boundary of each object in each dental cross-sectional image and the tooth number of each tooth, which are obtained through the tooth division neural network and the tooth detection neural network.
