Abstract
A method of scanning an oral cavity including: acquiring, using an intraoral scanner (IOS) head, without changing a position of the IOS head, a first image of a first region of interest (ROI) and a second image of a second ROI where the first and the second ROIs are of different portions of a dental arch of the oral cavity and do not overlap; reconstructing depth information for the first and the second ROI; and generating a single model of the dental arch by combing the depth information.
Claims20
An intraoral scanner (IOS) comprising:
- a plurality of imagers;
- a plurality of pattern projectors, wherein each of the plurality of pattern projectors is configured to:
- project a pattern of structured light, and
- include a baseline length from each of said plurality of imagers;
- and
- a processor configured to:
- determine a working distance of a region of interest (ROI) from said intraoral scanner (IOS) using one or more images acquired by one or more of said plurality of imagers,
- select a baseline length separating a pattern projector of said plurality of projectors and an imager of said plurality of imagers, at a given time, based on said working distance, and
- automatically select said pattern projector and said imager for illumination and imaging the region of interest (ROI).
