Abstract

This paper discusses the methods of analysis needed to determine accurately the spatial pattern of the swing of a golfer. Results are presented using this analysis for golfers of differing ability. A categorisation appears simply from considering the results.

Keywords: Golf, swing, categorisation, velocity, photogrammetry.


1 Introduction

This paper describes the work to date in a study undertaken in the department of Mechanical Engineering at the University of Nottingham. The work is still ongoing as part of a Ph.D. thesis.

Much work done has been done in the past on the kinematic analysis of the golf swing. Initial work such as that by Jorgenson ( 1) and Williams ( 2) covered two dimensional analyses of the swing. Later contributors to the field such as Vaughan ( 3) extended the work to full three dimensional analysis of the motion. Almost the entire body of work however concerns the analysis of a single subject, usually a golf professional or a top amateur. Even where more than one subject has been studied, usually the results of only one subject have been presented. This is testament to the difficulty of this type of study. This paper presents initial results of a study which differs greatly from previous work. We aim to present three dimensional kinematic analysis of the swings of more than one subject, and moreover of subjects of differing abilities from professional to rank amateur, with the aim of comparing and contrasting these swings. We hope to show how these swings may be categorised according to certain characteristic kinematic behaviours and how this information might be used to improve club design.


2. Method

The basis of the work is photographic analysis of the swing, in particular the analysis of the position and orientation of the club at known time intervals in order to derive velocities and accelerations by differentiation. It was hoped at the start to produce an analysis system that was cheap to set up and use so that others in the field could also
