摘　　要：讨论了虚拟现实技术在三维数字人体和穴位研究中的应用。在融合了腧穴组织结构信息的三维数字人体基础上,根据各组织的物理特性,分析针灸过程中针体与组织的相互作用力,以及部分行针模式中的力感特征,建立力学模型模拟针体受力,并通过力反馈设备真实地传递给操作者,为视觉和触觉信息融合一体的三维针灸人体建模作了初步探索,为针灸教学提供了一种动态的仿真手段。This paper discusses the application of virtual reality technology in the 3-D visible human body and acupuncture research, Based on the 3-D visible human fused with the localization information and hierarchy of acupoints, the paper analyzes the force against the needle and haptic rendering during the needle manipulation according to the physical properties of different tissues. A haptic model is constructed to demonstrate the force behaviors dunng acupuncture, and the force will be produced and passed to the manipulator by a force feedback device, It enriches the contents of 3-D visible human project, provides a dynamic simulation instrument for acupuncture teaching, and supplies a platform for acupuncture research.
