Gait analysis method and, system, and apparatus device for improving walking obstacle

Abstract

The present disclosure provides a gait analysis method and system, and an apparatus for improving a walking obstacle. The method includes: acquiring three-axis acceleration data and three-axis angular velocity data collected by an inertial sensor, and acquiring pressure data collected by a pressure sensor; performing a quaternion operation on the three-axis acceleration data and the three-axis angular velocity data to acquire three-axis acceleration and a three-axis Euler angle corresponding to a ground coordinate system; identifying a swinging state and a stationary state of feet based on the three-axis acceleration data and the pressure data; analyzing based on the three-axis acceleration, the three-axis Euler angle, and the swinging state and the stationary state of the feet to acquire gait parameters related to a straight walking process, a turning processing, a feet to ground angle, and a feet tremor; and uploading the gait parameters to a server.
