VIEWFINDER WITH REAL-TIME TRACKING FOR INTRAORAL SCANNING

摘要

Methods and systems for scanning an intraoral cavity of a patient provide capturing one or more viewfinder 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 viewfinder images. The methods and systems further provide capturing a viewfinder 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.

主权项

1. A method for guiding scanning of an intraoral cavity of a patient, the method comprising:
capturing one or more viewfinder images of one or more portions of the intraoral cavity of the patient, each of said one or more viewfinder images corresponding to a field of view of an intraoral scanner; scanning the one or more portions of the intraoral cavity with the intraoral scanner to generate one or more topography scans of the one or more portions of the intraoral cavity, the one or more topography scans corresponding to the one or more viewfinder images; capturing a viewfinder image of a portion of the intraoral cavity, the viewfinder image overlapping with the one or more viewfinder images; determining an area of overlap of the viewfinder image with the one or more viewfinder images; and displaying one or more indicators of the area of overlap on one or more locations of a display in order to provide guidance for positioning the field of view of the intraoral scanner.
