摘要： In embodiments set forth herein, an intraoral scanning system includes a first intraoral scanner, a second intraoral scanner, and a computing device wirelessly connected to both the first intraoral scanner and the second intraoral scanner. The computing device receives first intraoral scan data from the first intraoral scanner and generates a first three-dimensional (3D) surface of at least a portion of a first patient's dental arch based on the first intraoral scan data. The computing device further receives second intraoral scan data from the second intraoral scanner and generates a second 3D surface of at least a portion of a second patient's dental arch based on the second intraoral scan data.

摘要： Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.

摘要： The present disclosure provides computing device implemented methods, computing device readable media, and systems for motion compensation in a three dimensional scan. Motion compensation can include receiving three-dimensional (3D) scans of a dentition, estimating a motion trajectory from one scan to another, and calculating a corrected scan by compensating for the motion tfajectory. Estimating the motion trajectory can include one or more of: registering a scan to another scan and determining whether an amount of movement between the scans is within a registration threshold; determining an optical flow based on local motion between consecutive two-dimensional (2D) images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow; and estimating an amount of motion of a 3D scanner during the scan as a rigid body transformation based on input from a position tracking device.

摘要： A system (100) comprises a scanner (180), an augmented reality (AR) display (150) and a computing device (105). The scanner (180) generates intraoral images (163) of a dental arch and the AR display generates additional image data (162) representative of a view from a wearer of the AR display (150). The computing device (105) receives the intraoral images (163) from the intraoral scanner (180), generates a virtual three-dimensional model of at least a portion of the dental arch from the intraoral images (163), receives the additional image data (162) from the AR display, determines, from the additional image data (162), a region of the view that is outside of the dental arch, generates a visual overlay (164) comprising the virtual three-dimensional model, and sends the visual overlay (164) to the AR display (150). The AR display (150) displays the visual overlay (164) such that the virtual three-dimensional model is shown in the region of the view that is outside of the dental arch.

摘要： The current document is directed to methods and systems for guiding a wand for scanning one or more surfaces of a three-dimensional, solid object, in particular, within the oral cavity of a patient, as well as for providing semi-automated and automated training to technicians who use oral-cavity-imaging-and-modeling systems to accurately and efficiently generate three-dimensional models of patients' teeth and underlying tissues. The methods and systems are implemented either as subsystems within oral-cavity-imaging-and-modeling systems or as separate system in electronic communication oral-cavity-imaging-and- modeling systems. The methods and systems use an already generated, digital, three- dimensional model of a portion of the oral cavity of a particular patient or of a physical model of a portion of an oral cavity to compute a temporal, translational, and rotational trajectory of an oral-cavity-imaging-and-modeling endoscope, or wand, during a training scan.

摘要： Methods and systems for scanning an intraoral cavity of a patient provide capturing one or more viewfmder images of the intraoral cavity and scanning the intraoral cavity with an intraoral scanner to generate one or more topography scans of the intraoral cavity. The one or more topography scans may correspond to the one or more viewfmder images. The methods and systems further provide capturing a viewfmder image of a portion of the intraoral cavity, the viewfinder image overlapping with the one or more viewfinder images. An area of overlap of the viewfinder image with the one or more viewfinder images can be determined. One or more indicators of the area of overlap can be displayed on one or more locations of a display in order to provide guidance for positioning a field of view of the intraoral scanner.

摘要： An apparatus is described for measuring surface topography of a three-dimensional structure. In many embodiments, the apparatus is configured to focus each of a plurality of light beams to a respective fixed focal position relative to the apparatus. The apparatus measures a characteristic of each of a plurality of returned light beams that are generated by illuminating the three-dimensional structure with the light beams. The characteristic is measured for a plurality of different positions and/or orientations between the apparatus and the three-dimensional structure. Surface topography of the three-dimensional structure is determined based at least in part on the measured characteristic of the returned light beams for the plurality of different positions and/or orientations between the apparatus and the three-dimensional structure.
