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.
Claims19
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, wherein the multiple light conditions include capturing different light intensities from multiple light sources, and wherein each light source from the multiple light sources generate light having a different light intensity than each of the other light sources;
- comparing the light intensities from at least two of the images within the sequence of images to one another;
- and
- estimating the surface texture of the tooth based on the comparison of the light intensities from the at least two images within the sequence of images, wherein the estimated surface texture is added to a dental model providing dental detail.

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, wherein the different light condition includes capturing different light intensities from multiple light sources in each individual image, and wherein each light source from the multiple light sources generate light having a different light intensity than each of the other light sources;
- comparing the light intensities from at least two of the individual images within the sequence to one another;
- and
- estimating the surface texture of the tooth based on the comparison of the light intensities from the at least two individual images within the sequence of images, wherein the estimated surface texture is added to a dental model providing dental detail.
