三维扫描及其衍生技术在医学领域的应用进展

Application progress of 3D scanning and its derivative technique in medical field

三维扫描技术是利用扫描设备对物体进行快速扫描,获得其表面或内部结构各点的空间关系,利用计算机构建物体的立体图像,并对重建的三维图像进行观察、测量及分析等处理后获得被扫描物体特征数据的一项科学技术,以其为基础衍生出虚拟现实、导航和3D打印等多项现代技术,在测绘、建模、制造、服装设计及医学等多个领域应用广泛。通过重点介绍三维扫描技术的原理及特点,综述分析三维扫描及其衍生技术在医学领域的应用现状,并拓展其应用思路。

Three-dimensional(3D)scanning is one kind of science technique that uses scanning equipment to quickly scan objects so as to obtain the spatial relations of various points on objects’surfaces or internal structures,and uses computer to construct stereo images of objects,and obtains characteristic data of scanned object after the reconstructed 3D image was observed,measured,analyzed and other process.At present,many modern technologies,such as VR(Virtual Reality),navigation and 3D printing,derivative from it,and it has been developed and been widely used in mapping,modeling,manufacture,costume design,medicine and many fields.Through emphatically introduces the principle and characteristics of 3D scanning technique,this paper summarizes the application status of 3D scanning technique and its derivative technique in medical field,and expands application thought of them.
