3D MEASUREMENTS OF 2D INTRAORAL IMAGES

原文（中国語）

Methods and systems are described that generate three-dimensional (3D) measurements from points in two-dimensional (2D) images. An example method includes determining an alignment between a 2D image of a dental site and a 3D surface of the dental site, determining a first point and a second point in the 2D image, projecting the first point and the second point onto the 3D surface based on the alignment between the 2D image and the 3D surface, performing a measurement of a distance between the projected first point and the projected second point on the 3D surface, and displaying at least one of a) a first visualization of the measurement on the 2D image or b) a second visualization of the measurement on the 3D surface.
