Abstract:The method of quantitative measurement of gait makes a profound influence on many fields,such as clinical medicine,biped robot control strategy and so on.A gait analysis platform is established based on inertial measurement unit (IMU)combining wireless sensor network.Two IMU sensor nodes are bound on the left and right ankles so that the acceleration and angular velocity can be obtained from both sides at the same time and sent to remote terminal.Based on pattern recognition, time series analysis,threshold detection,zero velocity correction and various data fusion methods,the gait parameters are calculated.Furthermore,dual gait parameters,such as the dual stand phase and dual gait period can be obtained by the proposed sensor data fusion method.Dual stand phase detection has an important significance to the human activity recognition.The experimental results show that this study achieves high calculation accuracy.
