The method of catching real comprehensive three-dimensional data of national dance is proposed in this paper. Guided by the method, the three-dimensional data of wave dance is captured. Meanwhile, how to generate dance animation based on national dance three-dimensional data is introduced to demonstrate the applications of dance 3D data. The modeling with the ethnic characteristics is developed and bound with biped skeleton. And then, the modeling with the skeleton is bound with three-dimensional data of natural dance so as to generate the animation driven by the dance 3D data. The efficiency of generating animation is improved. The work of this paper shows that using the motion-capture technology can protect China' s national dance art and culture , and promoting the methods of catching three-dimensional data of natural dance based on motion capture technology will have a positive social and economic benefit.%研究民族舞蹈三维动捕数据真实全面的获取方法,并以此方法指导摆手舞的三维数据采集.同时本文以舞蹈动画生成为例介绍民族舞蹈三维数据化的后期应用,建立带有民族特色角色建模并辅以骨骼绑定,而后将角色模型与动捕数据进行运动数据绑定,以实现舞蹈三维动捕数据驱动角色模型生成动画的目标,动画制作的效率得到了提高.表明动作捕捉技术可用于保护我国民族舞蹈艺术文化,基于动捕技术的民族舞蹈三维数字化方法的推广将产生积极的社会效益和经济效益.
