摘　　要：人体足底压力特征与步态特征高度相关,脚步中形态的变化会对足部承压产生较大的影响。由于特殊人群-例如残疾人的行走规则不符合对称性原则,导致当前的承载力计算模型没有考虑这种非对称性对足底压力特征带来的影响,导致准确性不高。提出采用支持向量机的足底压力特征的计算方法。利用压力测试板采集特殊人群的足底压力特征图像,进行预处理,并提取关键特征作为足底压力特征计算的依据,引入支持向量机(SVM)的"一对一"分类模式对足底压力特征图像进行训练和计算,完成对足底压力特征的准确计算。仿真结果表明,利用改进算法进行特殊人群人体足底压力特征计算,能够提高计算率,为人体足底压力分析提供了科学依据。A calculation method of the plantar pressure characteristics based on the support vector machine is proposed. The pressure test board is used, the image of the plantar pressure characteristics of the special population is collected, and then the key characteristics are extracted to be as the basis for the calculation of the plantar pressure characteristics. The image of plantar pressure characteristics is trained and calculated by introducing the ＂ one to one＂ classification model of support vector machine （ SVM）, and the accurate calculation of plantar pressure charac- teristics is performed. The simulation results show that proposed algorithm can improve the calculation rate and pro- vide scientific basis for the plantar pressure analysis of human body.
