ゴルフスイングを表現する評価モデルの構築

抄録

The purpose of this study is to propose brand-new 2-dimentional model to estimate golfer's swing motion. This model was constructed to take singular value decomposition and prototype with approximative polygon to the typical points of a body picked up a series of 2-dimentional photographs. Usually, many results of analysis by using 3-dimentional method are reported. There is no discussion about relationship between the results of 2-dimentional method and 3-dimentional method. Further more, there is no information about superiority of 2-dimentional method. According to this study the following results were obtained. The relationship between actual golfer's swing motion and whole rhythm represented by the combined motions of each body joint has been solved with singular value decomposition. And 2-dimentional prototype cleared how to use each body joint. As a result, 2-dimentional method threw light on difficult problem to reproduce the golfer's swing motion.
