🏌️‍♂️Golf-Ball-Trajectory-Estimation

시계열 데이터 기반 골프공 궤적 예측 모델 개발 프로젝트

Untitled

YOLOv8 모델을 통해 골프공의 초기 움직임을 포착하고,

프레임 속 골프공의 3차원 상의 위치(x, y, z) 만으로 전체 골프공의 궤적을 예측하는 모델을 개발하였습니다.

📂Dataset:

  • Train dataset: 4,500

  • Validation dataset: 500

  • 데이터 생성 model: Linear regression

  • Initial velocity(초기 공의 속도): 공이 뜨기 시작했을 때의 속도

  • Spin rate(스핀량)

  • Spin axis(스핀축)

  • xz theta(x와 z 사이 각도): 공이 휘어진 각도

🚀Model:

  • Machine learning: linear regression
  • LSTM model

궤적 예측 model: LSTM
