GOLF SWING ANALYSIS APPARATUS
First Claim
1. A golf swing analysis apparatus for analyzing a golf swing that uses a golf club having a grip, a shaft and a head, comprising:
- a derivation unit configured to derive analytical data including at least one of time-series angular velocity data and time-series acceleration data in an analysis time interval near impact, from sensor data output from at least one of an angular velocity sensor and an acceleration sensor attached to at least one of the grip and the shaft;
a calculation unit configured to calculate a feature amount of a waveform of the analytical data; and
an estimation unit configured to estimate an impact position of a ball on a face of the head, according to the feature amount.

Abstract
A golf swing analysis apparatus capable of estimating the strike point of the ball on the face in a simple manner when a golf club is swung is provided. The apparatus is provided with a derivation unit, a calculation unit, and an estimation unit to analyze a swing using a golf club having a grip, a shaft and a head. The derivation unit derives analytical data including at least one of time-series angular velocity data and time-series acceleration data in an analysis time interval near impact, from sensor data output from at least one of an angular velocity sensor and an acceleration sensor attached to at least one of the grip and the shaft. The calculation unit calculates a feature amount of a waveform of the analytical data. The estimation unit estimates an impact position of a ball on a face of the head, according to the feature amount.
