The purpose of this study was to determine the validity and reliability of a new method for measuring three-dimensional (3D) putting stroke kinematics using the TOMI device. A putting robot and a high-speed camera were used to simultaneously collect data for the validity evaluation. The TOMI device, when used in conjunction with standard 3D coordinate data processing techniques, was found to be a valid and reliable method for measuring face angle, stroke path, putter speed, and impact spot at the moment of ball contact. The validity of the TOMI(R) measurement system was quantified using the 95% limits of agreement method for each aforementioned variable. The practical significance of each validity score was assessed by incorporating the maximum estimated measurement error into the stroke of the putting robot for 10 consecutive putts. All putts were executed from a distance of 4 m on a straight and flat synthetic putting surface. Since all putts were holed successfully, the measurement error for each variable was deemed to be negligible for the purposes of measuring putting stroke kinematics. The influence of key kinematic errors, at impact, on the outcome of a putt was also determined.
本研究旨在确定使用 TOMI 设备测量三维（3D）推杆运动学的新方法的有效性和可靠性。推杆机器人和高速摄像机被用于同时收集数据以进行有效性评估。当与标准的 3D 坐标数据处理技术结合使用时，TOMI 设备被发现是一种有效且可靠的方法，可用于测量击球瞬间的面角、击球路径、推杆速度和撞击点。通过在推杆机器人的 10 次连续推杆中加入最大估计测量误差，使用 95%的一致性界限法对每个上述变量的有效性得分进行量化。所有推杆均在 4 米距离的直平合成推杆表面上进行。由于所有推杆均成功入洞，因此对于测量推杆运动学，认为每个变量的测量误差可以忽略不计。还确定了在击球时关键运动学误差对推杆结果的影响。
