    摘要: The present disclosure relates to a scanning system for generating a three-dimensional (3D) representation of an object, the scanning system comprising: an intraoral scanning device comprising one or more projector units configured to project a pattern on a surface of the object; two or more camera units configured to acquire a set of images comprising at least one image from each camera unit, wherein each image is composed of an array of pixels, wherein each pixel comprises a pixel color defined by one or more color channels; wherein the scanning system further comprises one or more processors configured for: determining points in three-dimensional (3D) space that form a solution to a correspondence problem associated with the set of images, wherein the points are determined by comparing pixel colors with computed colors associated with camera rays corresponding to each pixel; and generating the three-dimensional (3D) representation based on the determined 3D points.
