发明名称 Scanner system and method for mapping surface of three-dimensional object
摘要 A scanning system is disclosed including a hand-held scanning device for capturing three-dimensional information of an object. The scanner system includes a high-speed transceiver having a high-speed laser light source, a high frequency MEMS oscillating scanning mirror and software for frame registration. Laser based range finding technique is used to map the scanned object. MEMS oscillating at high speed enables rapid and accurate scanning of an 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. 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. Several benefits from the scanner are possible: much higher resolution of the scanned object, improved acquisition speed of the three-dimensional information of the surface of the object to be mapped, and the improvement in virtual image clarity.
