專利摘要(中)
一種擊球運動器材擊球點位置偵測方法及裝置。此方法包括下列步驟：擷取震動感測器偵測擊球運動器材與球體撞擊所產生的震動而生成的震動訊號；對震動訊號進行頻譜分析，以獲得震動訊號在頻域上的多個特徵頻率；以及利用各個特徵頻率的振幅計算至少一筆特徵資訊並輸入使用機器學習預先建立的一預測模型，以估測球體在擊球運動器材上的撞擊位置，其中預測模型經使用多個震動訊號的特徵資訊及對應的多個撞擊位置訓練。

專利摘要(英)
A method and an apparatus for impact position detection of impact sport equipment are provided. The method includes following steps: receiving a vibration signal generated by a vibration sensor detecting vibration caused by collision of impact sport equipment and a ball; performing a spectrum analysis on the vibration signal to obtain eigenfrequencies of the vibration signal in a frequency domain; and calculating at least one piece of characteristic information by using an amplitude of each eigenfrequency and inputting the same into a prediction model established in advance by using machine learning, so as to estimate an impact location of the ball on the impact sport equipment, in which the prediction model is trained by using characteristic information of multiple vibration signals and corresponding impact locations.
