Abstract
Embodiments for estimating a surface texture of a tooth are described herein. One method embodiment includes collecting a sequence of images utilizing multiple light conditions using an intra-oral imaging device and estimating the surface texture of the tooth based on the sequence of images.
Claims20
A computing device implemented method for estimating a surface texture of a tooth, comprising:
- collecting a sequence of images utilizing multiple light conditions using an intra-oral imaging device;
- comparing at least two of the images within the sequence of images to one another;
- estimating the surface texture of the tooth based on the comparison of the at least two images within the sequence of images;
- and
- converting the estimated surface texture of the tooth into a surface normal vector for each pixel of at least one of the two images.

A non-transitory computing device readable medium having executable instructions that can be executed by a processor to cause a computing device to perform a method for estimating a surface texture of a tooth, comprising:
- receiving a sequence of scanned images of a tooth from a dental device, the sequence including a number of individual images, each individual image collected under a different light condition;
- comparing at least two of the individual images within the sequence to one another;
- estimating the surface texture of the tooth based on the comparison of the at least two individual images within the sequence of images;
- and
- converting the estimated surface texture of the tooth into a surface normal vector for each pixel of at least one of the individual images.
