摘要：

背景：三维测量技术在逆向工程、质量检测、虚拟现实等各种领域的广泛应用，也逐渐进入到医学领域。选择安全、准确、快速、具有较高性价比的测量方法，可获得满足临床需求的测量数据，提供精确的手术模拟效果。
目的：综述激光扫描与三维特征提取技术在临床中的应用，并对应用中的主要技术进行分析。
方法：由第一作者检索2000/2009中国期刊全文数据库(http://ckrd.cnki.net)，万方数据库(http://www.wanfangdata.com.cn)及ScienceDirect数据库(http://www.sciencedirect.com)中已发表的关于利用激光扫描进行三维特征提取以及在临床中应用的文献，中文检索词为“激光扫描，三维重建，临床应用”，英文检索词为“laser scanning, three-dimensional reconstruction， clinical application”。
结果与结论：激光扫描进行三维特征提取完全能够满足临床要求，并已经广泛用于口腔正畸学、额面外科、整形设计、矫形设计、康复研究等领域，并且相比于CT，MRI等传统方法，具有快速、精确，对人体无伤害的优点；通过对利用激光扫描进行特征提取主要技术的研究，发现相关技术可以很好的满足临床要求，但是也存在一些问题，比如进行数据分块需要通过交互方式或迭代方式给出，不能自动分块；重构物体是由许多面片组成，这些面片对于造型处理起来也不直观；发展基于集成的逆向工程技术，包括测量技术、基于特征和集成的模型重建技术、基于网络的协同设计和数字化制造技术以及如何快速准确的提取特征等都是以后研究的主要内容。

Abstract:

BACKGROUND: Three-dimensional measuring technique is widely used in reverse engineering, quality inspection, virtual reality and other fields, and gradually enters into the medical field at the same time. The data meet clinical requirement and provide accurate simulation about surgery through choosing safe, accurate, rapid and high cost-effective measuring method.
OBJECTIVE: To summarize the clinical application of laser scanning and three-dimensional character acquisition and to analyze the main technologies of application.
METHODS: Literatures about three-dimensional character acquisition using laser scanning and clinical application were searched from Chinese Journal Full-text database, WanFang database and Sciencedirect Database by the first author. These literatures have been published from 2000 to 2009 were selected. The key terms were “laser scanning, three-dimensional reconstruction and clinical application” both in English and Chinese, respectively.
RESULTS AND CONCLUSIONS: Three-dimensional character acquisition using laser scanning was fully capable to meet clinical requirements and has been widely used in the field of orthopedic, plastic surgery, rehabilitation research and so on. Compared with CT, MRI and other traditional methods, it is rapid, accuracy and harmless to human body. Through the researches of main technology of character acquisition using laser scanning, it has been discovered that clinical requirements could be met fully through interrelated technologies. However, there are some problems, such as the segment of data must be given through an interactive or iterative process, cannot be automatically. Development of reverse engineering technology basing on integration, including measuring techniques, reconstruction techniques based on features and integration, collaborative design and digital manufacturing technology based on network, and how to extract characters quickly and accurately, all will be done in the future.
