Abstract

As the golfing population increases, there is an increasing need for an analysis system capable of analyzing the user's own swing posture. In this paper, we define six main analysis items for constructing golf swing motion analysis system based on inertial sensors. Motion data was acquired for teaching pros and general users using inertial sensors based motion capture system, and analyzed through the proposed system. As a result of general swing motion analysis, the upper body and head movements were larger and the twist angle was lower by 25 degrees than the teaching pros. The swing tempo, which has a large effect on the swing trajectory, was also confirmed to be kept short compared to the expert, and the swing speed was slower. Experts confirmed that the plane of the backswing and the downswing occur on the same plane, whereas the general user's plane has fallen away from the impact point and the address point.

골프를 즐기는 인구가 증가함에 따라 사용자 스스로 본인의 스윙 자세 분석이 가능한 분석 시스템의 필요성이 증가하고 있다. 본 논문에서는 관성센서 기반의 골프 스윙 모션 분석 시스템 구축을 위해 주요 분석 항목 6가지를 정의하였다. 관성센서 기반 모션캡쳐 시스템을 이용해 티칭프로와 일반인을 대상으로 모션 데이터를 취득하고, 제안한 시스템을 통한 분석을 수행하였다. 일반인과 티칭프로의 스윙 분석 결과, 일반인은 티칭 프로에 비해 상체 및 머리 움직임이 더 크게 나타났으며, 꼬임각은 약 25도 낮게 나타났다. 스윙 궤적에 큰 영향을 미치는 스윙 템포 또한 전문가에 비해 짧게 유지하는 것을 확인하였고, 스윙 스피드도 더 느리게 나타남을 확인하였다. 또한, 전문가는 백스윙과 다운스윙의 플레인이 동일한 평면상에서 발생하는데 비해 일반인은 임팩트 지점과 어드레스 지점이 떨어져 나타나는 것을 확인하였다.
