Provided is a method of performing registration between a plurality of images of different dimensions. The method may be performed by one or more processors of a computing device, and may include primarily positioning a three-dimensional (3D) image by identifying a first landmark in the 3D image, generating a registration image by registration between the primarily positioned 3D image and a two-dimensional (2D) image, and secondarily positioning the registration image.

No: 18/173546 Application Filed: February 23, 2023 Assignees: 3D ONS, INC. (Seoul, KR) Claim: 1. A method of performing registration between a plurality of images of different dimensions by one or more processors of a computing device, the method comprising: primarily positioning a three-dimensional (3D) image by identifying a first landmark in the 3D image; generating a registration image by registration between the primarily positioned 3D image and a two-dimensional (2D) image; and secondarily positioning the registration image. Claim: 2. The method of claim 1, wherein the 3D image comprises a computed tomography (CT) image obtained by photographing an upper-and-lower jaw area, and the 2D image comprises a cephalo image obtained by X-raying a profile of a face. Claim: 3. The method of claim 1, wherein the first landmark comprises a first landmark (A) and a first landmark (B) related to left and right sides of a face and a first landmark (C) and a first landmark (D) related to front and rear sides of the face, and the primary positioning of the 3D image comprises: performing y-axis rotation about the first landmark (C) to match a z-coordinate of the first landmark (A) with a z-coordinate of the first landmark (B); and performing z-axis rotation about the first landmark (C) to match a y-coordinate of the first landmark (A) with a y-coordinate of the first landmark (B). Claim: 4. The method of claim 3, wherein the generating of the registration image comprises: matching directions of a head and the face in the 3D image with those of the head and the face in the 2D image; converting a size of the 2D image on the basis of the first landmark in the 3D image and a second landmark in the 2D image; and overlapping the 3D image and the 2D image by moving the size-converted 2D image on the basis of coordinates of the first landmark in the 3D image, and the second landmark comprises a second landmark (A) and a second landmark (B) related to the front and rear sides of the face. Claim: 5. The method of claim 4, wherein the matching of the directions of the head and the face in the 3D image with those in the head and the face in the 2D image comprises causing the head to be oriented in a positive z-axis direction and the face to be orientated in a negative y-axis direction. Claim: 6. The method of claim 4, wherein the converting of the size of the 2D image on the basis of the first landmark in the 3D image and the second landmark in the 2D image comprises: identifying a first straight line connecting the first landmark (C) and the first landmark (D) in the 3D image; identifying a second straight line connecting the second landmark (A) and the second landmark (B) in the 2D image; and obtaining a size conversion ratio on the basis of the first straight line and the second straight line, and converting the size of the 2D image on the basis of the obtained size conversion ratio. Claim: 7. The method of claim 4, wherein the overlapping of the 3D image and the 2D image by moving the size-converted 2D image on the basis of the coordinates of the first landmark on the 3D image comprises: moving the size-converted 2D image to match coordinates of the second landmark (A) with the coordinates of the first landmark (C); and rotating the 2D image about the x-axis to overlap a first straight line connecting the first landmark (C) and the first landmark (D) in the 3D image and a second straight line connecting the second landmark (A) and the second landmark (B) in the 2D image. Claim: 8. The method of claim 1, wherein the secondary positioning of the registration image comprises secondarily positioning the registration image on the basis of a third landmark in the registration image, wherein the third landmark comprises a third landmark (A) related to an orbitale, a third landmark (B) related to a porion, and a third landmark (C) related to a nasion. Claim: 9. The method of claim 8, wherein the secondary positioning of the registration image comprises: performing rotation about the x-axis to cause a first line connecting the third landmark (A) and the third landmark (B) to be parallel with the y-axis; and performing parallel translation of the registration image to cause the third landmark (C) in the rotated registration image to be an origin. Claim: 10. An apparatus for performing the method of claim 1, comprising: a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, wherein the processor executes the one or more instructions to perform the method of claim 1. Claim: 11. A recording medium readable by a computing device, which is hardware, and storing a program for performing the method of claim 1 when the recording medium is combined with the computing device.
