  "textContent": "The present disclosure discloses a method, apparatus and system for motion tracking. The method includes: acquiring inertia information and pace ranging information of feet of a target object; determining step length information according to the inertia information and the pace ranging information; determining pace direction information according to the inertia information, and determining motion direction information of the target object according to the pace direction information; and determining a motion position of the target object according to the motion direction information and the step length information, and accordingly determining the motion track according to the motion position. By applying the technical schemes provided by embodiments of the present disclosure, the problem that an obvious accumulated drift error is likely to occur in direction estimation in the prior art, which interferes with position determination and brings negative effects can be solved, and beneficial effects of improving positioning accuracy and stability are achieved.",
