Abstract: A non-transitory medium includes instructions for generating a three-dimensional virtual model of an intraoral object by receiving surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of an intraoral scanner, wherein the surface scan data comprises data for a plurality of points of the intraoral object, and adjusting the data for one or more of the plurality of points to compensate for one or more inaccuracies associated with changes of a shape of a focusing surface. A three-dimensional virtual model of the intraoral object is generated using the adjusted data.

Abstract: An imaging apparatus includes a first and second light source, focusing optics, a probe, a detector, an optical transmission medium and a color sensor. The first light source is to generate light beams that travel through the focusing optics along an optical path to the probe. The probe directs the light beams toward a three dimensional object to be imaged. The detector detects returning light beams that are reflected off of the three dimensional object and directed back through the probe and the focusing optics. The second light source is to generate multi-chromatic light. The optical transmission medium is outside of the optical path and is to receive a ray of the multi-chromatic light reflected off of a spot on the three dimensional object and through the probe. The color sensor is to receive the ray from the optical transmission medium and determine a color of the spot on the three dimensional object.

Abstract: Embodiments are directed to an imaging apparatus, which in an embodiment includes a light source to provide light, optics, a translation mechanism and a detector. The optics include focusing optics to perform focusing of the light onto a non-flat focal surface and to direct the light toward a three dimensional object. The translation mechanism adjusts a location of at least one lens of the focusing optics to displace the non-flat focal surface. The detector measures intensities of returning light that is reflected off of the three dimensional object, wherein the intensities of the returning light are measured for a plurality of locations of the at least one lens for determination of positions of a plurality of points of the three dimensional object. Detected positions of one or more of the plurality of points are adjusted to compensate for the non-flat focal surface.

Abstract: A confocal imaging apparatus includes an illumination module to generate an array of light beams. Focusing optics perform confocal focusing of an array of light beams onto a non-flat focal surface and direct the array of light beams toward a three dimensional object to be imaged. A translation mechanism adjusts a location of at least one lens to displace the non-flat focal surface along an imaging axis. A detector measures intensities of an array of returning light beams that are reflected off of the three dimensional object and directed back through the focusing optics. Intensities of the array of returning light beams are measured for locations of the at least one lens for determination of positions on the imaging axis of points of the three dimensional object. Detected positions of one or more points are adjusted to compensate for the non-flat focal surface.

Abstract: An intraoral scanner includes a probe housing disposed at a distal end of an elongate wand. The intraoral scanner further includes a window structure coupled to the probe housing. The window structure and the probe housing form an interior volume. The window structure has a concave transverse cross section. The intraoral scanner further includes optical components disposed within the interior volume. The optical components include a first camera having a first orientation and a second camera having a second orientation that is different than the first orientation. The first camera and the second camera are to capture images of dental sites.

Abstract: Methods and apparatuses (including systems and devices), including computer-implemented methods for segmenting, correcting and/or modifying a three-dimensional (3D) model of a subject's oral cavity to determine individual components such as teeth, gingiva, tongue, palate, etc., that may be selective and/or collectively digitally manipulated. In some implementations, artificial intelligence uses libraries of labeled 2D images and 3D dental models to learn how to segment a 3D dental model of a subject's oral cavity using 2D images, height map and/or other data and projection values that relate the 2D images to the 3D model. As noted herein, the dental classes can include a variety of intra-oral and extra-oral objects and can be represented as binary values, discrete values, a continuum of height map data, etc. In some implementations, several dental classes are predicted concurrently.

Abstract: An intraoral scanner comprises one or more structured light projectors and two or more cameras, where each structured light projector projects a pattern of light onto an intraoral three-dimensional (3D) surface and the two or more cameras capture one or more sets of images, wherein each image includes at least a portion of the projected pattern of light. A processor solves a correspondence problem within a set of images of the one or more sets of images such that points in 3D space are determined based on correspondence of captured features in the set of images to projected features of at least the portion of the projected pattern, wherein said points in 3D space form a solution to the correspondence problem. The processor calibrates the intraoral scanner by performing an adjustment to stored calibration data associated with the intraoral scanner based on the solution to the correspondence problem.
