Abstract
A hit position estimation device includes a sensor and a calculation unit. The sensor is attached to a shaft of a golf club and outputs a sensor signal including twisting of the shaft. The calculation unit estimates a position at which a ball hits a head from a twist component when the ball hits the head of the golf club, by using the sensor signal.
Claims16
A hit position estimation device for sports equipment including a columnar portion and a hitting portion connected to the columnar portion, comprising:
- a sensor that is attached to the columnar portion and is not attached to the hitting portion, and that is configured to output a sensor signal including a twist component caused by twisting of the columnar portion;
- and
- a processor configured to estimate a position at which the hitting portion is externally pressured, by using the twist component of the sensor signal when the hitting portion is externally pressured.
A hit position estimation method for sports equipment including a columnar portion and a hitting portion connected to the columnar portion, comprising:
- outputting, by a sensor that is attached to the columnar portion and is not attached to the hitting portion, a sensor signal including a twist component caused by twisting of the columnar portion;
- and
- estimating, by using the twist component of the sensor signal when the hitting portion is externally pressured, a position at which the hitting portion is externally pressured.
