    Abstract: A tracking system and a tracking method using the same are disclosed. The tracking system includes a marker, a camera unit, a first inertial measuring unit, a second inertial measuring unit and a tracking processing unit. The marker is fixed on the measurement object, and the camera unit outputs a marker image by photographing the marker. The first inertial measuring unit is fixed on the camera unit, and measures and outputs first inertia comprising first accelerated velocity and first angular velocity. The second inertial measuring unit is fixed to one of the measurement object and the marker, and measures and outputs second inertia comprising second accelerated velocity and second angular velocity. The tracking processing unit primarily extracts the position and the posture of the measurement object using the marker image, and secondarily extracts the position and the posture of the measurement object using the first and second inertias.
