Abstract
A method of and system for analyzing golf swings is described. A three dimensional android computer model of a human as well as a parametric dynamic computer model of a golf club are generated and combined. In addition, the three dimensional motions of a person swinging a golf club are recorded using cameras that track reflective markers placed at various locations on the person. A computer processes the marker path data to calculate three dimensional angular motions of the body segments of the person and the golf club which is then used to kinematically drive the joints of the android model to effect superposition of the recorded golf swing on the android model and golf club model. Kinetic data derived from the analysis of the model may in turn be used to dynamically drive the joints of the android model to also superimpose the recorded swing on the models. The results are used, among other things, to study the biomechanics of the golfer and the performance of the golf club.
