Abstract
The systems and methods disclosed herein employ superposition of two-dimensional video and a rendered, three-dimensional image to provide visual feedback during acquisition and analysis of three-dimensional data. These systems and methods may be usefully employed in a context such as dentistry to assist in the acquisition of highly detailed and accurate digital dental models from the dentition of a dental patient.
Claims23
A method comprising:
- acquiring a three-dimensional surface representation of an anatomic structure from a scanner as a plurality of fitted three-dimensional surface scans;
- and
- superimposing the three-dimensional surface representation and a two-dimensional video image of the anatomic structure in a display while acquiring the three-dimensional surface representation, wherein the three-dimensional surface representation and the two-dimensional video image are each displayed from a current point of view of the scanner.
A computer program product embodied in a non-transitory computer readable medium that, when executing on one or more computing devices, performs the steps of:
- acquiring a three-dimensional surface representation of an anatomic structure from a scanner as a plurality of fitted three-dimensional surface scans;
- and
- superimposing the three-dimensional surface representation and a two-dimensional video image of the anatomic structure in a display while acquiring the three-dimensional surface representation, wherein the three-dimensional surface representation and the two-dimensional video images are each displayed from a current point of view of the scanner.
A system comprising:
- a scanner for acquiring a three-dimensional surface representation of an anatomic structure as a plurality of fitted three-dimensional surface scans;
- a processor for superimposing the three-dimensional surface representation onto a two-dimensional video image of the anatomic structure while acquiring the three-dimensional surface representation to provide a superimposed video image, wherein each of the three-dimensional surface representation and the two-dimensional video image are rendered from a current point of view of the scanner;
- and
- a display for displaying the superimposed video image.
