1. A system for measuring a golf club head having a club face, the system comprising:

  • at least three markers placed on the club face, the marker placement adapted to (1) define the geometry of the club face without further calibration, and (2) conform to a known tolerance of relative spacing and orientation between the markers;

    at least two cameras adapted to capture a plurality of images of the markers during a swing and communicating those images to a processor;

    the processor configured to perform the following steps;

    a. performing threshold processing on the images to detect pixels that may correspond to the markers;

    b. determining a position for the markers in three dimensional space;

    c. finding a group of markers that fall within the tolerance of a known geometric relationship;

    d. labeling the markers based on their position with respect to the known geometric relationship; and

    e. calculating the position of the club head during the swing based on the 3D position of the markers.
