Title:
METHOD FOR DETERMINING REGISTRATION ACCURACY OF THREE-DIMENSIONAL DENTAL CT IMAGE AND THREE-DIMENSIONAL DIGITAL IMPRESSION MODEL, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH PROGRAM FOR EXECUTING SAME IN COMPUTER IS RECORDED
Document Type and Number:
WIPO Patent Application WO/2022/131419
Kind Code:
A1
Abstract:
A method for determining the registration accuracy of a three-dimensional dental CT image and a three-dimensional digital impression model comprises the steps of: generating a scan projection image by two-dimensionally projecting three-dimensional scan data in registration data in which the three-dimensional scan data and three-dimensional CT data are registered; generating a CT projection image by two-dimensionally projecting the three-dimensional CT data in the registration data; determining front registration accuracy by inputting, into a first convolutional neural network model, a front scan projection image in the front-vertical direction and a front CT projection image in the front-vertical direction; determining lateral registration accuracy by inputting, into a second convolutional neural network model, a lateral scan projection image in the lateral-vertical direction and a lateral CT projection image in the lateral-vertical direction; and determining the final registration accuracy of the registration data on the basis of the front registration accuracy and the lateral registration accuracy.
