Abstract
An object of the present invention is to provide a system and method for measurement and analysis of a behavior of a golf club head. Specifically, the system comprises 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.
