Abstract:
A positioning method is disclosed. The positioning method includes collecting at least two types of sensor data reflecting a motion state of a terminal device in a step-counting period in real time; separately filtering the at least two types of sensor data to obtain filtered sensor data; step-counting a user holding the terminal device based on the filtered sensor data to obtain a distance and a direction of movement of the user in the step-counting period; and correcting current position information of the user based on the distance and the direction of the movement of the user in the step-counting period to implement positioning of the user. The technical solution provided in the present disclosure can be adopted to improve the accuracy of indoor positioning.
