Publication number: 20240138961Abstract: A dental scanning system comprises an intraoral scanner and one or more processors. The intraoral scanner comprises one or more light projectors configured to project a pattern (comprising a plurality of pattern features) on a surface of a dental object, and two or more cameras configured to acquire one or more sets of images, wherein each set of images comprises at least one image from each camera, and wherein each image includes at least a portion of the projected pattern. The processors are configured to determine one or more image features within each set of images, solve a correspondence problem within each set of images such that points in 3D space are determined based on the image features, wherein said points form a solution to the correspondence problem, and wherein the correspondence problem is solved for groups of pattern features, and generate a digital 3D representation of the dental object using the solution to the correspondence problem.Type: ApplicationFiled: October 11, 2023Publication date: May 2, 2024Inventors: Ofer Saphier, Yossef Atiya, Arkady Rudnitsky, Nir Makmel, Sergei Ozerov, Tal Verker, Tal Levy

Patent number: 11930154Abstract: An intraoral scanning system comprises and intraoral scanner and a processor. The intraoral scanner comprises one or more cameras and one or more structured light projectors, the intraoral scanner to generate a series of images using the one or more cameras, each image including at least a portion of a pattern projected by the one or more structured light projectors onto an intraoral three-dimensional surface. The processor runs a correspondence algorithm to compute respective three-dimensional positions of a plurality of features of the pattern on the intraoral three-dimensional surface, as captured in the series of images. The processor identifies the computed three-dimensional position of a detected feature of the pattern as corresponding to a particular projector ray r, in at least a subset of the series of images. The processor tracks the particular projector ray r across one or more additional images of the series of images.Type: GrantFiled: January 18, 2023Date of Patent: March 12, 2024Assignee: Align Technology, Inc.Inventors: Ofer Saphier, Tal Levy, Gal Peleg, Eliran Dafna, Sergei Ozerov, Tal Verker, Nir Makmel, Yossef Atiya
