10. A method for manufacturing a three-dimensional dental laminate by a system, the method comprising:
receiving images including a user's teeth;
estimating poses of a camera by analyzing the received images;
computing sparse 3D points by tracking feature points in the received images and triangulating a three-dimensional position of the feature points based on relative movements among the estimated poses of the camera;
generating a three-dimensional tooth modeling file based on the sparse 3D points;
adjusting a tooth size of the generated three-dimensional tooth modeling file for the size of an actual tooth;
generating a three-dimensional dental laminate modeling file based on the three-dimensional tooth modeling file adjusted to have the same size as the actual tooth; and
manufacturing a three-dimensional dental laminate based on the generated three-dimensional dental laminate modeling file.
