Abstract: An intraoral scanner and computing system for capturing images and generating three-dimensional models. The intraoral scanner includes a handle, a mouthpiece extending from the handle, a flood illuminator projecting light from the mouthpiece, a structured light projector projecting a light pattern from the mouthpiece, and stereo camera capturing images through the mouthpiece. An optimal image of each of different materials within the captured images are combined to create a high dynamic range image. The structured light pattern in the high dynamic range image is used to determine three-dimensional measurements and create a three-dimensional model.
