Measurement of putting golf ball's motion using a vision sensor

摘要

This paper presents measurement of a putting golf ball jump motion using a vision sensor. After putting, a golf ball experiences bouncing, sliding and rolling sequentially. In particular, ball jump motion contains lots of important information related to impact such as jump number, height and length. Putting is simulated as a simple pendulum and golf ball jumps are measured using a vision sensor. The golf ball jump changes significantly according to impact errors such as impact timings. If an IMU sensor is attached on the putter head and relationship between variations of golf ball trajectory and IMU sensor signal is characterized, coaching information of golf putting to correct various impact errors can be provided only using IMU sensor.
