METHOD FOR AUTOMATICALLY DETECTING LANDMARK IN THREE-DIMENSIONAL DENTAL SCAN DATA, AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM FOR EXECUTING SAME IN COMPUTER RECORDED THEREON

摘要

A method for automatically detecting a landmark in three-dimensional dental scan data comprises the steps of: generating a two-dimensional depth image by projecting the three-dimensional scan data; using a convolutional neural network model to identify whether the two-dimensional depth image is full arch data obtained by scanning all the teeth of a patient or partial arch data obtained by scanning only a portion of the teeth of the patient; detecting a two-dimensional landmark within the two-dimensional depth image by using the fully-connected convolutional neural network model; and detecting a three-dimensional landmark in the three-dimensional scan data by inversely projecting the two-dimensional landmark onto the three-dimensional scan data.
