Claim 0:
1. A method for impact position detection of impact sport equipment, detecting, by using a vibration sensor mounted on impact sport equipment, an impact position by an apparatus for impact position detection of impact sport equipment comprising a processor, the method comprising following steps:
retrieving a vibration signal generated by the vibration sensor detecting a vibration caused by impact of the impact sport equipment and a ball;
performing a spectrum analysis on the vibration signal to obtain a plurality of eigenfrequencies of the vibration signal in a frequency domain; and
calculating at least one piece of characteristic information by using an amplitude of each of the eigenfrequencies and inputting the same into a prediction model established in advance by using machine learning, so as to estimate an impact position of the ball on the impact sport equipment, wherein the prediction model is trained by using the characteristic information of multiple vibration signals and corresponding impact positions.
