Abstract:
A method of generating a three-dimensional virtual model of an intraoral object includes capturing, by an imaging apparatus for performing intraoral scans, surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of the imaging apparatus, wherein the surface scan data comprises depth data for a plurality of points of the intraoral object. The method further includes adjusting the depth data for one or more of the plurality of points based at least in part on the position of the at least one lens associated with the depth data for the one or more of the plurality of points. The method further includes generating the three-dimensional virtual model of the intraoral object using the adjusted depth data.

Claim (Index 22):
An imaging apparatus for performing intraoral scans, comprising:\n a light source to provide light; an optical system comprising a plurality of lenses disposed along an optical path of the light, wherein the optical system comprises focusing optics to perform focusing of the light onto a focal surface and to direct the light toward a three dimensional object to be imaged in an oral cavity, the focusing optics comprising at least one lens of the plurality of lenses; a translation mechanism to adjust a location of the at least one lens to displace the focal surface along an imaging axis defined by the optical path, wherein adjustments to the location of the at least one lens cause a change in magnification of the focal surface; a detector to measure returning light that is reflected off of the three dimensional object and directed back through the focusing optics; and one or more processor to:\n determine positions of a plurality of points of the three dimensional object based on the measured returning light; and \n adjust the determined positions of one or more of the plurality of points to compensate for respective magnifications of the focal surface associated with respective locations of the at least one lens.
