Abstract
Official abstract text for this publication.
A teeth movement tracking device, including: an input unit for receiving three-dimensional teeth data and image data having the shape of teeth; an image processing unit for combining the three-dimensional teeth data with the image data; a movement tracking unit for detecting the axis of rotation with respect to the rotation of the teeth or temporomandibular joint by analyzing the image data or the three-dimensional teeth data; and a trajectory generation unit for calculating the movement trajectory of the teeth or the temporomandibular joint by analyzing the image data or the three-dimensional teeth data.
First claim
Opening claim text (preview).
1 . A teeth movement tracking device, comprising: an input unit for receiving three-dimensional teeth data and image data having the shape of teeth; an image processing unit for combining the three-dimensional teeth data with the image data; a movement tracking unit for detecting the axis of rotation with respect to the rotation of the teeth or temporomandibular joint by analyzing the image data or the three-dimensional teeth data; and a trajectory generation unit for calculating the movement trajectory of the teeth or the temporomandibular joint by analyzing the image data or the three-dimensional teeth data. 2 . The teeth movement tracking device of claim 1 , wherein the image processing unit aligns the three-dimensional teeth data with the image data and synchronizes the movement thereof. 3 . The teeth movement tracking device of claim 1 , wherein the input unit receives the image data having two or more continuity. 4 . The teeth movement tracking device of claim 1 , wherein the image processing unit converts all or part of the image data into three-dimensional data. 5 . The teeth movement tracking device of claim 4 , wherein the three-dimensional data are converted by using a feature point or an attached target on the image data. 6 . The teeth movement tracking device of claim 1 , wherein the movement tracking unit detects the axis of rotation by analyzing the movement of the teeth data or the image data. 7 . The teeth movement tracking device of claim 6 , wherein the movement tracking unit detects the axis of rotation by determining the section having the least movement in the teeth data or the image data. 8 . The teeth movement tracking device of claim 1 , wherein the trajectory generation unit tracks the rotation or free motion of the teeth or the temporomandibular joint with respect to the axis of rotation detected by the movement tracking unit. 9 . A teeth movement tracking method, comprising: receiving three-dimensional teeth data and image data having the shape of teeth by scanning a face; combining the three-dimensional teeth data with the image data; detecting the axis of rotation with respect to the rotation of the teeth or temporomandibular joint by analyzing the image data or the three-dimensional teeth data; and calculating the movement trajectory of the teeth or the temporomandibular joint by analyzing the image data or the three-dimensional teeth data. 10 . The teeth movement tracking method of claim 9 , wherein the receiving the image data inputs the image data having two or more continuity. 11 . The teeth movement tracking method of claim 9 , wherein the combining the three-dimensional teeth data with the image data aligns the three-dimensional teeth data with the image data and synchronizes the movement thereof. 12 . The teeth movement tracking method of claim 9 , wherein the combining the three-dimensional teeth data with the image data further comprises converting all or part of the image data into three-dimensional data. 13 . The teeth movement tracking method of claim 12 , wherein the three-dimensional data are converted by using a feature point or an attached target on the image data. 14 . The teeth movement tracking method of claim 9 , wherein the detecting the axis of rotation detects the axis of rotation by analyzing the movement of the teeth data or the image data. 15 . The teeth movement tracking method of claim 14 , wherein the detecting the axis of rotation detects the axis of rotation by determining the section having the least movement in the teeth data or the image data. 16 . The teeth movement tracking method of claim 9 , wherein the calculating the movement trajectory tracks the rotation or free motion of the teeth or the temporomandibular joint with respect to the detected axis of rotation.
