    摘要： An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device captures images of an object of interest, e.g., patient teeth or associated anatomy, by projecting the light source as a first series of frames, and a second series of frames. The first series of frames projects first pattern data, and the second series of frames projects second data. The second series of frames are interleaved between frames in the first series of frames. The frames in the first series are partially-illuminated and are used to capture data for a 3D model. The frames in the second series are preferably fully- illuminated and are used to generate a live preview of the object. By displaying the live preview frames in juxtaposition to the 3D model, the operator is provided with visual feedback of the object.
