3 Method for recognizing teeth from 3D teeth data and apparatus therefor

摘要

Disclosed are a method and an apparatus for recognizing a tooth region in a three-dimensional tooth image. The tooth region recognition device creates a plurality of first spheres in the inner space of the three-dimensional tooth image, and after expanding the volume of the plurality of first spheres to a preset first size, the first sphere remaining in the inner space of the three-dimensional tooth image is reduced to a preset second size, and when the first sphere of the second size is moved and positioned in the tooth direction, the position of each tooth is determined based on the position of the first sphere.
