激光扫描在头面部软组织三维重建和测量中的应用

Application of laser scanning for three-dimensional reconstruction and anthropometrics of facial soft tissue

近年来,随着科学和计算机技术的发展,人们对头面部软组织的研究已经由二维发展到三维,用于三维重建的技术也越来越多,包括直接测量法、莫尔云纹法、形态分析法、激光扫描法、结构光测量法、立体摄影测量技术、光栅投影测量法和电子计算机断层扫描技术等。其中,激光扫描是目前比较先进的技术之一。尽管受很多因素的影响,但笔者相信随着技术的不断改进和完善,激光扫描在头面部软组织三维重建中将得到更加广泛的应用。本文将从激光扫描技术的原理、技术构成、特点及其在头面部软组织三维重建方面的应用等内容进行综述。

In recent years,with the development of the science and the computer technology,people on the right track facial soft tissue research has developed from the two-dimensional to three-dimensional,and more and more technologies can be used for the three-dimensional reconstruction,including direct measurements,moiré to-pography,morphanalysis,laser scanning,structured light,stereophotography,grating projection,computed tomogra-phy,and so on.Laser scanning is one of the more advanced technologies.Although affected by many factors,we believe that as technology continues to improve and perfect,laser scanning in the three-dimensional reconstruction of facial soft tissue will be more widely used.This review is about the principle,the technical composition,the characteristics and the applications of laser scanning technology.
