Accurate step number statistical method fusing sole pressure and IMU (Inertial Measurement Unit) sensor

The invention provides an accurate step number statistical method fusing sole pressure and an I MU sensor, and relates to the technical field of medical rehabilitation and artificial intelligence, and the method comprises the steps: S1, collecting information of a sole pressure sensor; s2, acquiring information of a heel I MU sensor; s3, sensor temperature excursion compensation based on a PI D temperature excursion compensation strategy; s4, based on gait classification of machine learning, effective gaits and invalid gaits are distinguished; and S5, counting effective gaits, and accurately counting the number of steps. According to the method, the problems of temperature excursion caused by temperature change and temperature change speed, low step counting precision of a single sensor and invalid gait counting of multiple sensors are solved, the preprocessing capability of the sensor is improved, the measurement precision is improved, the gait counting precision is obviously improved, and the method has wid
