摘要
目的探讨人体行走运动主要步态特征参数新的提取识别方法和定量化分析技术。方法以步态分析技术与传统的足迹检验理论和方法为基础,运用先进的Simi Motion视频动作捕捉系统,对50名健康男性正常行走的步态特征参数进行识别和分析。结果提出了一种基于关节点的步态特征提取方法,得到了行走步态特征的基本参数,为步态特征定量化检验提供技术支持。结论研究表明,simi视频动作捕捉系统可以获得较精确的步态特征数据,能够满足人体步态分析的需求,进而达到人身个体识别的目的。
Objective To explore a new method for the extraction,recognition and quantification analysis of the major gait feature parameters of human walking.Method Base on the gait analysis techniques and traditional theories and methods of footprint examination,the gait parameters of 50 healthy men were recognized and analyzed with the advanced Simi Motion Capture System.Results A gait feature extraction method based on joint point was proposed,and the basic parameters of gait features were summarized.Conclusion The research shows that the Simi Motion Capture System can acquire more accurate data of gait features,and meet the needs of gait analysis.
