摘要
In this paper we present a new miniaturized 3D optical measurement system for tooth restoration. The system is designed for scanning tooth within human mouth. The measuring process is based on the structured light measurement principle. The novelty in the approach is characterized by the following features: a flexible optimization convergence algorithm is taken as the calibration of the special miniaturized system, a rapid phase-shifting method is used to measure the tooth shape, multi-view 3D registration is completed based on matching between scale invariant features of 2D image and the miniaturized device is constituted with the LCoS micro-display module and camera. Some experiments are performed to validate the availability and reliability of the developed system. This miniaturized measurement system has a wide applications for dental CAD/CAM restoration system. (C) 2012 Published by Elsevier GmbH.
