摘　　要：基于计算机视觉的人体运动捕捉技术为舞蹈动作的形式化与数字化描述提供了新思路。本文结合运动捕捉技术,设计了一种新的舞蹈动作的形式化描述语言。首先,以三维人体骨骼层次结构为描述对象,基于运动分析方法解析舞蹈动作捕捉数据,建立人体舞蹈动作描述模型;其次,利用拉班运动分析技术方法描述舞蹈动作,并进一步从时间、空间、重力和流畅度4种力效角度提取舞蹈动作肢体姿态特征,以实现对舞蹈动作形式化描述语言的定义;最后,开发了一种舞蹈动作分析与描述系统,为保护和传承民族舞蹈提供有效手段。The development of human motion capture technology based on computer vision provides a new idea for the formalization and digital description of dance movements.A new formal description language for dance movements with motion capture technology is described.First the three-dimensional human skeleton hierarchy is leveraged as the description object,the dance motion capture data are analyzed based on the motion analysis method and the human dance motion description model was established as well.Then,to define the formal description language of dance movements Laban motion analysis technique is utilized to describe dance movements and the body posture features of dance movements are further extracted from the perspectives of time,space,gravity and fluency.Finally,a dance movement analysis and description system is developed to provide an effective means for the protection and inheritance of national dance.
