摘要:
基于光路压缩原理,提出一种直接在口腔内进行扫描、实时获取牙体和软组织三维形貌的数字印模扫描技术.利用一组反射镜组成的光学导管进行传像,将投影光路和成像光路压缩在有限的空间内,解决了条纹投影三维测量轮廓术在口腔测量中阴影和遮挡的问题.依据该技术原理设计、制作了测量系统,并进行了相应的实验测量和精度评估.测量结果显示,该系统成像清晰,可靠性好、精度高,标准差可达4 μm.
Abstract:
A novel digital impression technique for scanning the 3D morphology of teeth and soft tissue inside the oral cavity in real time is presented.Using a light tube to transmit images,the technique compressed the projection rays and imaging rays in limited space,so that shadow and light occlusion of fringe projection 3D profilometry in the intraoral measurements can be avoided. A prototype system was fabricated according to the presented principles, and experimental measurements were made to evaluate the feasibility and accuracy of the system. The results demonstrate that the proposed technique acquires good robustness and great precision with a deviation of 4 μm in 3D imaging.
