1. Apparatus for analyzing a gold swing by a golfer holding a golf club comprising:
- (a) at least first and second electro-optical sensors having different fields of view encompassing said golfer and golf club during at least a portion of said golf swing;
(b) optical means for marking at least some significant body locations on said golfer and said golf club;
(c) means for determining the three-dimensional location of at least some of said optically marked locations at selected time intervals;
(d) means for storing said three-dimensional locations;
(e) means for displaying a time history of at least some of said stored three-dimensional locations; and
(f) said at least first and second electro-optical sensors having sensing axes located at least 30 degrees apart.

Abstract
A measurement system obtains and stores digital data on the positions of golf club and significant human body parts during a golf club swing. An interactive display allows later display of the measured performance for use in instruction or review. A coordinate transformer allows the viewing of a displayed simulated golfer from any aspect and at variable speeds and stop action. A generator such as an alphanumeric or graphic generator displays suggested display options, graphics, informative labels, and alphanumeric tabular data. Permanent copies of any displayed picture can be made for later home study.

9. 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. 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.
