    摘要: A scanning system includes a hand-held scanning device that generates two-dimensional images of a pattern reflected off an object. The system also includes a memory and processing unit. The memory stores a calibration table for the scanner and received scanned bitmap images. The processing unit generates three-dimensional information as to a scanned object. The scanning can be performed without knowledge or even precise control of the position of the object relative to the scanner. Random movement of the object during scanning is also possible. For example, the scanner is simply swept over the surface of the object by hand. Three-dimensional information of the object is obtained from the captured images using a calibration table for the scanner. A method of calibration of the scanner in X, Y and Z directions is also described. The scanner can be used for a variety of purposes, including medical and industrial purposes. The illustrated embodiment is in-vivo scanning of human teeth for purposes of orthodontic treatment planning and diagnosis.

    摘要: Methods for recognizing a virtual tooth surface, defining a virtual tooth coordinate system, and simulating a collision between virtual teeth are provided. Methods include receiving input data specifying a point on the rendered surface model associated with a tooth, deriving a perimeter on the surface model of the tooth, and analyzing the surface model along a plurality of paths outwardly extending from points on the perimeter. Methods also include receiving point input data, receiving axis input data that defines first and second axes associated with the virtual tooth, computing a substantially normal vector for a portion of the tooth surface surrounding the point, and computing a coordinate system. Methods also include receiving permissible movement input data directed to permissible movement of a first virtual tooth, bringing the first virtual tooth into contact with a second virtual tooth, and displaying data resulting from the simulation.
