三维光栅投影技术在面部轮廓三维重建中的应用

Three-dimensional reconstruction on facial soft tissue using three-dimensional grating projection technique

目的:试图建立一种面部软组织的快速三维重建方法。方法:采用工业用ATOS快速三维光学测量仪,对1例下颌骨发育过度患者的面部轮廓模型进行三维重建。结果:面部软组织的三维数据的采集精度高,生成的图像逼真。结论:本方法改进了传统的投影光栅装置,应用2个CCD摄像头接收信号,实现了对面部三维数据的快速精确采集。

PURPOSE:The purpose of this study is to establish a method to reconstruct the facial soft tissue three-dimensionally. METHODS: By ATOS three-dimensional opticalmetry, which used in industry, 3D data on facial profile of a patient with mandibular hyperplasia was achieved quickly. RESULTS: Three-dimensional data of facial profile was accurate and the images were reconstructed with verisimilitude. CONCLUSIONS:Traditional device of grating projection was modified by using two CCD cameras to obtain grating images.3D data on facial profile were achieved quickly and accurately.
