Human gait phase recognition based on wearable inertial sensing technology
In order to realize recognition of human gait phases based on wearable inertial sensing technolo-gy,the human gait phase recognition models based on feature selection,time proportion optimization,and machine learning with multiple data types,multiple features,and multiple classifiers were developed to rec-ognize the human gait phases,and the recognition effect of the three models are compared.The results show that the average accuracy of human gait phase recognition based on feature selection is 73.66%,on time proportion optimization is 90.96%,and on machine learning models trained with pedal pitch angle data and acceleration data is 97.04%and 86.80%,respectively.Different recognition methods can be selectively used according to different human gait phases and application scenarios to achieve desired recognition effects.The comprehensive use of time proportion optimization algorithm and machine learning methods can achieve high comprehensive recognition accuracy.The paper provides a reference for further research on human behavior based on wearable sensors.
