三坐标测量机以精密机械为基础，综合应用了光学、电子、计算机等先进技术，使其成为一种先进精密的测试仪器。本文简要地介绍了传统三坐标测量机发展的现状，结合虚拟现实技术，提出了三坐标测量机的一个新的发展方向——虚拟坐标测量机（ＶＣＭＭ），同时阐述了虚拟坐标测量机的概念、组成和实现方法，并说明了活动桥式虚拟坐标测量机的运行环境。 CMM to precision machinery as the basis, the integrated application of optics, electronics, computers and other advanced technology, making it an advanced and sophisticated test equipment. This paper briefly introduces the current situation of the development of the traditional CMM. Combined with the virtual reality technology, this paper presents a new developing direction of the CMM, the Virtual Coordinate Measuring Machine (VCMM) and the concept of virtual CMM , Composition and implementation methods, and illustrates the operating environment of the active bridge virtual coordinate measuring machine.
