| 摘 要： | 为了缩短体育运动中人体运动技能分析过程人体模型构建周期和提高构建精度。采用激光扫描
技术,对自由式滑雪运动员在助滑阶段的几个主要动作进行数据采集,以“实物-设计意图-三维重构-再
设计”框架为流程,建立自由式滑雪运动员三维人体模型。研究发现在采用激光扫描技术得到表面的几何
数据基础上,人体模型的构建还要经过数据拼合、简化、三角化、去噪等预处理,再进行测量数据分块、
曲面拟合,最终进行模型重构。探讨了运动生物力学研究领域人体模型构建的新方法,提高人体模型构建
效率,为体育科学人体运动研究提供基础模型。

| Abstract: | In order to shorten the analysis process of human body movement skills and human
body model building cycle, and improve the building precision, the paper, by means of laser
scanning technology, collects the data of the freestyle skiing athletes'' main actions in
slipping stage, and establishes freestyle skiing athletes three-dimensional human body
model, taking "objects - design intent - 3D reconstruction -redesign as a framework. It is
found that the human body model building needs such pretreatments as data integration,
simplification, triangularization, and denosing on the basis of applying the laser scanning
technology in the geometric data, and then the measurement of data block and curved surface
fitting, finally the reconstruction of the model. The paper makes a research on the new way
of the human body model building in the sports biomechanics fields, aiming at improving the
efficiency of human body model building, and providing the basic model for the human
movement study in sports science. |
