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 system for analyzing a surface texture of a tooth, the system comprising:
- one or more computing devices including memory having executable instructions stored thereon that, wherein the executable instructions, when executed by one or more processors, cause the one or more computing devices to:
- collect a plurality of images of a same area of the tooth at different light conditions;
- compare an intensity of light at the same area of the tooth at the different light conditions to determine a surface normal vector for the same area of the tooth based on the different light conditions;
- and
- adding a detail to a dental model based on the surface normal vector.

A system for analyzing a surface texture of a tooth, the system comprising:
- one or more computing devices including memory having executable instructions stored thereon that, wherein the executable instructions, when executed by one or more processors, cause the one or more computing devices to:
- illuminate an area of a tooth using light sources of a dental scanning device;
- collect a plurality of images using the dental scanning device, wherein the plurality of images are of a same area of the tooth using different light conditions;
- compare an intensity of light at the same area of the tooth at the different light conditions to determine a surface normal vector for the same area of the tooth based on the different light conditions;
- and
- adding a detail to a dental model based on the surface normal vector.
