Gait monitoring method, gait monitoring device and wearable device

The application provides a gait monitoring method, a gait monitoring device and a wearable device. The method comprises acquiring a plurality of data segments corresponding to touchdown of a foot when a user is running, determining feature data used for analyzing the gait from the plurality of data segments; inputting the feature data into a trained mathematic model to obtain a gait monitoring result of the user's running process. By adopting the technical scheme provided by the invention, a user can correctly know his gait without professional guidance, and appropriately adjust his gait according to the gait monitoring result, the user's running level can be raised, and sports injury can be prevented.
