Measurement of 3-D Loci and Attitudes of the Golf Driver Head While Swinging

Abstract

This paper describes a novel method to measure the loci and attitudes of a high-speed moving object in a three-dimensional space. Here, the method to the golf driver head is applied. The employed sensor is a line-charge-coupled device (CCD) camera with a high-speed scanning. Because the camera captures only one-dimensional (line) information in a two-dimensional image, the scanning speed is very high. During a measurement, the line-CCD camera captures the positions of markers located on the driver head. Simple signal processing yields the position at every scan interval and estimates the loci and attitudes of the golf club head. Here, the method to the golf head motion measurement is applied: However, it can be applied to a variety of high-speed moving objects other than a driver head
