项目摘要

The purpose of this project is to discuss and examine the method to organize. human motion data with the goal of building a human motion database and its retrieval system.The general operation of information organization requires three processes; (1)to convert raw data to primary information which must be segmented into manipulated units for the benefit of information storage and retrieval; (2)to generate secondary information from primary one, such as description, annotation, and cataloging data; (3)to make reasonable linkage between primary information and secondary one for effective and efficient use of information. As a case study of information organization for human motion data, the investigator has studied classical ballet movements thoroughly. (1)To convert raw data into primary information, 3D motion data were captured from demonstrations of professional ballet dancers using motion capture systems, and the data were segmented with the help of ballet technique format. The investigator made exhaustive catalog of ballet basic movements within the scope of elementary lesson, and 84 basic poses and 583 basic steps were identified and classified hierarchically for the segmentation. (2)To generate description of ballet movements, the investigator proposes a new description coding system. 84 poses and 583 steps were given mnemonic codes uniquely. Furthermore the notation method for short choreographies of ballet lessons is proposed.A Web-based motion data archive and 3DCG choreography simulation system, which is called "Web3D Dance Composer," have been also developed. The archive has accumulated 3D human motion data of basic ballet steps segmented. The system allows ballet teachers to create various choreographies for lessons and to represent them as 3DCG animations in the Web environment.

本课题的目的是探讨和检验组织的方法。人体运动数据的信息组织一般需要经过三个过程：（1）将原始数据转换为主信息，主信息必须被分割成便于存储和检索的操作单元;（2）从主信息生成辅助信息，如描述、注释和编目数据;（3）合理衔接主次信息，有效利用信息。作为人体运动数据信息组织的案例研究，研究者深入研究了古典芭蕾舞动作。(1)To将原始数据转换为原始信息，使用动作捕捉系统从专业芭蕾舞演员的演示中捕捉3D动作数据，并在芭蕾舞技术格式的帮助下对数据进行分割。研究者在芭蕾基础课范围内对芭蕾基本动作进行了详尽的分类，确定了84个基本姿势和583个基本步，并对它们进行了层次化分类。(2)To产生芭蕾舞动作的描述，研究者提出了一个新的描述编码系统。84个姿势和583个步骤被唯一地赋予了记忆码。在此基础上，提出了芭蕾舞短剧的记谱方法，并开发了基于Web的动作数据存档和3DCG编舞仿真系统--“Web 3D Dance Composer”。该档案库积累了基本芭蕾舞步分割的三维人体运动数据。该系统允许芭蕾舞教师创建各种舞蹈的教训，并表示为3DCG动画在Web环境中。
