The human posture detection and behavior analysis have a wide range of practical value.A system based on plantar pressure was designed for body posture detection and behavior analysis.It consisted of pressure acquisition module,data processing module,wireless communication module and behavior analysis software.Posture detection system acquires the foot pressure data and communicates via Bluetooth.Behavior analysis software uses mutli-class support vector machine to distinguish the five classic human postures of sitting,standing,walking,running and climbing.Experiments show that the system has good recognition accuracy and reliability to human posture,and can be used in human posture detection and behavior analysis.%人体的运动姿态检测和行为分析具有广泛应用价值.设计了一种基于足底压力的人体姿态检测和行为分析系统,系统由压力采集模块、数据处理模块、无线通信模块和行为分析软件组成.姿态检测系统获取足底压力数据,采用蓝牙方式进行数据通信,行为分析软件使用支持向量机多分类方法实现坐、站、走、跑和爬楼5个经典人体姿态的区分.实验证明该系统对人体姿态具有较好的识别精度和可靠性,可以用于人体姿态检测和行为分析.
