动作捕捉技术在舞蹈姿态分析和教学中的实践研究

Research on Motion Capture Technology in Dance Posture Analysis and Teaching

为了将人体运动仿真技术应用到舞蹈姿态分析和教学研究中。研究了舞蹈姿态动作捕捉及分析,包括舞蹈动作的实时采集,舞蹈姿态的模型数据库建立,以及基于特征平面向量的21个关键节点和7个特征匹配平面的舞蹈姿态分析方法;然后,以某健美操班50名学员为实例,划分舞蹈基础和身体素质相当的两组分别进行常规教学和试验教学,试验对比组除了在动作幅度上低于常规组3.9分外,其在动作力度、规范程度方面的打分相比均高出9分以上。研究将动作捕捉技术与舞蹈教学和分析相结合,实现了舞蹈动作的直观反馈和分析,为科学的舞蹈教学提供了数据支撑。

In order to apply human motion simulation technology to dance posture analysis and teaching research,in this paper,the motion capture and analysis scheme of dance posture was firstly established,including real-time collection of dance movements,establishment of model database of dance posture,and analysis method of dance posture based on 21 key nodes and 7 feature matching planes of feature plane.Then,an aerobics class of 50 students was chose as an example,they were divided into two groups:conventional teaching and experiment teaching.The results show that the to conventional groups on the movement range was 3.9 points higher than control group,experimental control group,compared to grade the action strength,degree of specification were more than 9 points higher.The research in this paper combines motion capture technology with dance teaching and analysis,it provides intuitive feedback on dance movements,which provides data support for scientific training of dance.
