Abstract
A processing device performs image registration between a plurality of intraoral images of a dental site. The processing device identifies a candidate intraoral area of interest from a first intraoral image of the plurality of intraoral images. The processing device verifies the candidate intraoral area of interest as an intraoral area of interest based on a comparison of a second intraoral image to the first intraoral image. The processing device displays a view of the dental site where the intraoral area of interest is hidden and an indication of the hidden intraoral area of interest is visible.
Claims31
A computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- performing image registration between a plurality of intraoral images of a dental site;
- identifying a candidate intraoral area of interest from a first intraoral image of the plurality of intraoral images;
- making a comparison of a second intraoral image to the first intraoral image;
- determining whether to verify the candidate intraoral area of interest as an intraoral area of interest or to dismiss the candidate intraoral area of interest based on a result of the comparison;
- verifying the candidate intraoral area of interest as an intraoral area of interest;
- and
- displaying a view of the dental site where the intraoral area of interest is hidden and an indication of the hidden intraoral area of interest is visible.
A system comprising:
- a scanner to generate a plurality of intraoral images of a dental site;
- and
- a computing device operatively coupled to the scanner, the computing device to:
- perform image registration between two or more of the plurality of intraoral images;
- identify a candidate intraoral area of interest from a first intraoral image of the plurality of intraoral images;
- make a comparison of a second intraoral image to the first intraoral image;
- determine whether to verify the candidate intraoral area of interest as an intraoral area of interest or to dismiss the candidate intraoral area of interest based on a result of the comparison;
- verify the candidate intraoral area of interest as an intraoral area of interest;
- and
- display a view of the dental site where the intraoral area of interest is hidden and an indication of the hidden intraoral area of interest is visible.
A computer-implemented method comprising:
- performing image registration between a plurality of intraoral images of a dental site;
- identifying a candidate intraoral area of interest from a first intraoral image of the plurality of intraoral images;
- receiving a second intraoral image;
- making a comparison between the second intraoral image to the first intraoral image;
- determining whether to verify the candidate intraoral area of interest as an intraoral area of interest or to dismiss the candidate intraoral area of interest based on a result of the comparison;
- verifying the candidate intraoral area of interest as an intraoral area of interest;
- and
- displaying a view of the dental site where the intraoral area of interest is hidden and an indication of the hidden intraoral area of interest is visible.
