摘要

本論文利用IMU(慣性測量系統:加速度計、陀螺儀)硬體平台與webcam(網路攝影機)進行高爾夫推桿軌跡的可行性分析。目前大部份市售的高爾夫推桿練習器只能憑自己的感覺、肌肉記憶來調整推桿動作，無法記綠分析推桿的整個過程，而進口SAM PuttLab推桿分析儀不僅價格昂貴，體積龐大，操作也不方便。
本論文利用IMU與webcam體積小、重量輕價格便宜的特性，將加速度計與陀螺儀設計成位移、速度及角速度的感測元件，以及webcam裝置於球桿上量測推桿移動軌跡，在不影響推杆動作下，將整個推桿過程記錄下來，再將其量測訊號傳至PC，利用QT設計的圖形界面，真實反映推桿過程相關參數的變化及關係。透過電控精密三軸旋轉平台的設置數值來驗證本系統的量測值，其結果幾乎相同。希望本系統可以讓球友自我檢測推桿軌跡、桿頭旋轉角度、移動高度、擊球甜蜜點與手碗施力等資訊，協助球友修正推桿動作，進一步提昇推桿球技，也希望經由此論文的發表，能對高爾夫選手及教練在其學習與教學上能有所助益。

In this thesis, we are study the feasibility analysis of golf putting path by using the IMU (inertial measurement system) system, the hardware platform including accelerometers, gyroscopes, with a webcam. We can find the most of golf putting practice system from the market, there are just can make physical training only be their own feel or muscle memory to adjust the putter movement, can not remember the whole process of putting in the green analysis; the SAM PuttLab putt analyzer due to it is import equipment, it is not only expensive but also the physical size are huge, so it is very inconvenient.
the IMU system implement so many characters not only the price is lower and also we also including accelerometer and gyroscope into design to measurement the path, displacement, speed and angular of velocity. The system install the webcam on the club putter to recording the movement of trajectory, all the measurement procedure work without impact putter action, after record procedure thus the measurement signal transmitted to the PC. The system using QT graphical interface tracing the parameter changes of putter process. We verified all the value of measurement by using the electronically controlled precision three-axis rotary platform, the result is showing the same with the IMU.
This system allows golfers to self-detection of the putter track, including the angle of head rotation, the height of movement, hitting point on the sweet spot and hand bowl force information to help golfers correct putter action to further enhance the putter the game, also hope that through the publication of this thesis, golf players and coaches in their learning and teaching can be helpful.
