The kinematic modeling methods of CMM in virtual reality

虚拟现实中坐标测量机的运动建模是虚拟坐标测量机仿真运行的基础，是虚拟制造系统发展的需要。首先说明了虚拟现实、虚拟制造的基本概念和虚拟现实中坐标测量机运动建模的重要性，然后介绍了虚拟现实中坐标测量机几何建模、形象建模和运动建模之间的关系和运动建模方法，并针对运动建模中难以处理的光照模型变换进行了较详细的阐述，最后提出了虚拟现实中坐标测量机运动模型的开发运行环境。

The kinematic modeling of CMM in virtual reality lays the foundation for simulating and running of virtual coordinate measuring machine, in need of the development of virtual manufacturing system. Firstly interprets the basic concepts of virtual reality(VR) and virtual manufacturing(VM), along with the importance of CMM's kinematic modeling in virtual reality, secondly introduces the relationship of geometric modeling, image modeling and kinematic modeling, as well as the kinematic modeling methods, moreover expounds the lighting model transformation with which is difficult to deal in kinematic modeling in detail, thirdly presents the developing and running environments of CMM's kinematic model in virtual reality.
