Abstract: Abstract An intraoral scanning system comprising: an elongate handheld wand with a probe at a distal end; a structured light projector configured to project a uniform structured light pattern onto an object, the structured light projector comprising a light source configured to transmit light and a pattern generating optical element configured to generate the uniform structured light pattern when the light is transmitted from the light source and through the pattern generating optical element; a plurality of cameras configured to capture points of the uniform structured light pattern projected onto the object by the structured light projector; and one or more processors configured to: determine a correspondence between projected points in the uniform structured light pattern generated by the structured light projector and captured points of the uniform structured light pattern captured by the plurality of cameras viewing the uniform structured light pattern projected onto the object; and use triangulation and the determined correspondence to determine three-dimensional points in space associated with the captured points of the uniform structured light pattern captured by the plurality of cameras viewing the uniform structured light pattern projected onto the object

Abstract: An apparatus for intraoral scanning includes an elongate handheld wand that has a probe. One or more light projectors and two or more cameras are disposed within the probe. The light projectors each has a pattern generating optical element, which may use diffraction or refraction to form a light pattern. Each camera may be configured to focus between 1 mm and 30 mm from a lens that is farthest from the camera sensor. Other applications are also described.
