Abstract

In this paper, I propose an automatic extraction method of golf swing features using a practical TOF camera Kinect. I extracted 7 key swing frames and features using joints and depth information from a Kinect. I tested the proposed method on 50 swings from 10 players and showed the performace. It is meaningful that 3D swing features are extracted automatically using an inexpensive and simple system and specific numerical feature values can be used for the building of automatic swing analysis system.

본 논문에서는 실용적인 TOF 카메라인 키넥트(Kinect) 한 대를 이용하여 골프 스윙의 자동 분석에 필요한 스윙 특징들을 자동 추출하는 효율적인 방법을 제안하였다. 제안한 방법은 키넥트가 제공하는 관절정보와 깊이(Depth) 정보를 이용하여, 골프스윙에서 중요한 7개의 키프레임과 각 키프레임에서 중요한 스윙특징들을 자동 추출한다. 10명의 골퍼들로부터 구한 50회의 스윙데이터에 대하여 성능을 확인 하였다. 제안한 방법은 설치가 간단하면서도 비용이 저렴한 환경에서 의미 있는 3차원 골프스윙 특징 추출이 가능하고, 구체적인 수치 값을 자동으로 제시하므로 실제적인 자가 스윙분석 시스템 개발에 사용될 수 있다는 점에서 의의가 있다.
