摘　　要：随着科学技术和工业生产的发展,三维形貌测量技术在机器视觉、工业监控、机械工程和医学检测等领域的应用日益广泛。在三维形貌测量系统中引入数字投影设备,并且由计算机进行控制,以达到自动化测量的目的,在很大程度上推动了三维测量技术的发展。文中从理论和实践两方面深入研究了基于数字投影的三维形貌测量技术,对其测量原理进行了分析,并且对傅里叶变换形貌测量法(FTP)和相移形貌测量法(PSP)进行了研究,搭建了实际的实验系统,并且通过实验比较了这两种测量方法的优劣。With the development of technology and industrial production,three dimensional surface measurement is widely used in machine vision,industry monitoring,mechanical engineering,medical diagnosis etc.In order to realize digitized three-dimensional profilometry,digital projector controlled by computers is introduced into the system,so that the fully automatic profilometry could be achieved.In this paper,the principle of three-dimensional fringe pattern profilometry is analyzed,and Fourier transform profilometry and phase measuring profilometry are studied as well.And an experimental system is set up,and comparison of the two measuring methods is also given.
