Apparatus and method for analyzing a golf swing and displaying results

Apparatus for analyzing a golf swing by a golfer holding a golf club comprising:

• (a) means for marking at least some significant body locations on said golfer and golf club;
• (b) at least a first and second means for sensing the positions of each of said marking means at a plurality of times, said first and second means for sensing having respective sensing axes;
• (c) the sensing axes of said first and second sensors being at least 30 degrees apart;
• (d) triangulation means for calculating the three-dimensional location of at least some of said means for marking which are sensed by at least two of said sensors;
• (e) means for storing said three-dimensional locations for at least a subset of said plurality of times;
• (f) means for analyzing a subset of body and golf club three-dimensional locations as a connected subset of body and golf club segments;
• and
• (g) means for displaying said interpreted connected subset of body and golf club segments.

Apparatus for analyzing a golf swing by a golfer holding a golf club comprising:

• (a) pulsable light sources affixed to significant locations on said golfer's body and to said golf club;
• (b) at least two electro-optical sensors having their optical axes spaced at least 30 degrees apart;
• (c) said electro-optical sensors being responsive to energization of said light sources to provide signal outputs indicating the location of said light sources;
• (d) triangulation means for determining, at a plurality of times, the three-dimensional location of energized light sources which are simultaneously visible to at least two electro-optical sensors;
• (e) means for storing at least a subset of said three-dimensional locations;
• (f) means for interpreting said subset of three-dimensional locations as a connected subset of body and golf club segments;
• and
• (g) cathode ray tube display means for displaying said connected subset of body and golf club segments.
