【摘要】：研究目的:针对人体真实模型不能满足推拿正骨训练的需要,教学实验中采用粳米米袋进行推拿练习难以满足实际需求的现状,本研究对人体颈椎部位实现三维数据重建,并设计客观性、逼真性、通用性的实体模型,深入研究虚拟化技术的交互性,为三维数据模型和实体模型的交互奠定基础,这将有助于中医正骨推拿手法的传承和发展,推动传统中医事业的现代化发展。研究方法:以虚拟化技术为基础,通过质点—弹簧法实现人体三维数据模型的网格化重建,并建立动力学微分方程;利用3D打印将数据模型实体化,并通过医用橡胶皮筋、皮筋调节器对实体模型改进;实现实体模型的通用化,为建立三维数据模型和实体模型的交互,通过改进的欧拉法对数据模型形变过程进行形变求解。研究结果:基于人体颈椎部位实现三维数据模型网格化重建,并设计与数据模型相关的通用性实体模型,构建了质点—弹簧动力学方程,并利用改进的欧拉法对人体数据模型进行形变数值求解,得到数值结果。研究结论:依据三维数据模型设计的实体模型实现了操作模型的通用性,数据模型的形变求解为实体模型和数据模型的交互打下了基础,为逼真、客观的虚拟交互平台的建立提供了依据,推动了中医正骨推拿手法的传承和发展。
[Abstract]:Objective: in view of the fact that the real human body model can not meet the needs of orthopedic massage training, it is difficult to meet the actual needs by using japonica rice bag in the teaching experiment. In this study, the three-dimensional data reconstruction of human cervical vertebrae was realized. And design the objective, realistic, universal entity model, deeply study the interaction of virtualization technology, lay the foundation for the interaction between 3D data model and entity model, which will be helpful to the inheritance and development of traditional Chinese medicine orthopedic massage technique. To promote the modernization of traditional Chinese medicine. Methods: based on virtualization technology, the mesh reconstruction of human three-dimensional data model was realized by mass-spring method, and the dynamic differential equation was established. The data model is materialized by 3D printing, and the solid model is improved by medical rubber tendon and leather bar regulator. In order to establish the interaction between the 3D data model and the solid model, the deformation process of the data model is solved by the improved Euler method. Results: the three-dimensional data model mesh reconstruction was realized based on the cervical vertebrae, and the general entity model related to the data model was designed, and the mass-spring dynamic equation was constructed. The improved Euler method is used to solve the deformation of human body data model and the numerical results are obtained. Conclusion: the operational model is universal based on the solid model designed by the 3D data model. The deformation solution of the data model lays the foundation for the interaction between the entity model and the data model. The establishment of objective virtual interactive platform provides the basis and promotes the inheritance and development of traditional Chinese medicine orthopedic massage.
