System and method for measurement and analysis of behavior of golf club head in golf swing
First Claim
1. A measurement and analysis system for measuring and analyzing a head behavior when a golfer hits a golf ball by a golf club, comprising:
- a golf club used by the golfer and having at least one marker on a head, the marker is formed as a line perpendicular to the face or as at least two markers;
at least two cameras for imaging a golf swing by using the golf club; and
a measurement and analysis device having a marker recognition and positional information acquisition unit for recognizing the at least one marker and acquiring positional information of the recognized at least one marker, a vector calculation unit for calculating a first vector representing a direction of the head and a second vector representing a tangent vector of a trajectory of the head during the golf swing, and a vector angle change acquisition unit for calculating a vector angle between the first vector and the second vector and acquiring a time series change of the calculated vector angle.
