Apparatus And Methods To Track Movement Of Sports Implements
Methods, apparatus, systems, and articles of manufacture to track movement of sports implements are disclosed herein. An example sensing unit disclosed herein is to be coupled to a sports implement. The sensing unit includes an inertial measurement unit to obtain movement data of said sports implement during a swing of said sports implement and a swing analyzer to determine whether the swing is a horizontal shot or a vertical shot based on the movement data.
Claim CLM-00001. 1. A sensing unit to be coupled to a cricket bat, the sensing unit comprising:
an inertial measurement sensor to obtain movement data of the cricket bat during a swing of the cricket bat; and a swing analyzer to determine whether the swing is a horizontal shot or a vertical shot by:
calculating a first area defined by a path of the swing projected in a substantially horizontal plane and a reference point in the substantially horizontal plane;calculating a second area defined by the path of the swing projected in a substantially vertical plane and the reference point in the substantially vertical plane; andcomparing a ratio of the first area and the second area to a threshold.
Claim CLM-00008. 8. A sports tracking system comprising:
an inertial measurement sensor coupled to a cricket bat to obtain a plurality of measurements during a swing of the cricket bat; and a swing analyzer to determine whether the swing is a horizontal shot or a vertical shot by:
determining a first position and a second position of the swing based on the plurality of measurements;determining a first absolute sum of a horizontal angle change of the cricket bat between the first position and the second position;determining a second absolute sum of a vertical angle change of the cricket bat between the first position and the second position; andcomparing a ratio of the first absolute sum and the second absolute sum to a threshold.
