Analysis of Human Body Motion by Using Motion Capture Systems - Development of Three Dimensional Motion Database -

1)研究了利用运动捕捉系统记录和分析非物质文化遗产的方法。为了补充动作捕捉数据，还研究了使用多角度视频记录的可能性。此外，本文还对有关非物质文化财产的图像、视频、动作捕捉数据的归档方法进行了研究。2)提出了一种基于动作捕捉的肢体动作数据生成Labanotation舞曲的方法。该方法可用于记录和生成各种舞蹈动作的编码描述。身体运动的三维CG动画可以从生成的Labanotation数据中重现。3)研究了从运动捕捉数据中提取部分特征值的方法。其中之一是从身体运动中提取“暂停”。根据这些停顿的时间分布，可以对舞蹈进行比较。此外，还研究了从一组帧序列中提取表达舞蹈身体运动的典型帧的方法，以及从数据库中存储的运动数据中检索相似运动数据的方法。4)开发了舞蹈教育多媒体教材制作配套系统。利用该系统可以制作由动作捕捉数据、视频和配乐组成的多媒体素材。5)开发了LabanEditor交互式Labanotation编辑器。3D CG运动可以从Labanotation数据生成。该系统功能强大，可以记录各种舞蹈，也可以进行Labanotation教育。6)召开“动作捕捉与舞蹈研究”学术研讨会。

1) Methods of using motion capture systems for recording and analyzing intangible cultural properties have been investigated. Possibilities of using multiple angle video recording have been also studied in order to complement the motion-captured data. Furthermore, method of archiving image, video, motion captured data concerning to intangible cultural properties has been investigated.2) A method of generating Labanotation dance score from motion captured body motion data has been developed. This method can be used for recording and generating coded description of varieties of dance movement. 3D CG animation of body motion can be reproduced from generated Labanotation data.3) Methods of extracting some feature values from motion-captured data have been investigated. One of them is to extract "pause" from body motion. Comparison of dances can be made basing on the temporal distribution of these pauses. Also, a method of extracting some typical frames expressing the dance body motion form a sequence of frames, and a method of retrieving similar motion data from motion data stored in a database have been studied.4) A supporting system for developing multimedia teaching materials for dance education was developed. By using this system multimedia material which consists of motion-captured data, video and Labanotation score can be produced.5) Interactive Labanotation editor named LabanEditor has been developed. 3D CG motion can be generated from Labanotation data. This system is powerful for recording various dances as well as Labanotation education.6) Academic symposium "Motion capture and dance research" was held.
