US 2022/0072372 A1 · A METHOD FOR CALCULATING A SWING TRAJECTORY OF A GOLF CLUB USING RADAR SENSING DATA, A RADAR SENSING DEVICE USING THE SAME, AND A RECORDING MEDIUM READABLE BY A COMPUTING DEVICE RECORDING THE METHOD

Abstract

The present invention provides a method for calculating a swing trajectory of a golf club using radar sensing data capable of calculating a swing trajectory of a golf club therefrom, a radar sensing device using the same, and a recording medium readable by a computing device recording the calculation method, which calculates the position coordinate information of the golf club through the analysis of the radar signal separately from calculating the motion parameters for the ball through the analysis of the radar signal when the golfer hits the ball with the golf club, and effectively calculate the swing trajectory of the golf club from the calculated position coordinate information of the golf club.

Dependent claims

A method of calculating a swing trajectory of a golf club using radar sensing data generated by receiving reflected radar signals, the method comprising:

specifying an impact time point of a golf club and a ball using the radar sensing data;
generating a swing trajectory area for indicating a swing trajectory of the golf club from the radar sensing data;
setting an impact position at the specified impact time point on the swing trajectory area;
and
calculating the swing trajectory of the golf club generated by calculating the coordinates of the golf club at a plurality of sensing times before and after the impact time point on the swing trajectory area.

2 more elements

A radar sensing device comprising:

a signal transmitter for transmitting a radar signal;
a signal receiver for receiving a reflected signal reflected from the ball and the golf club with respect to the radar signal of the signal transmitter;
a signal analyzer for processing to:
specify an impact time point of the golf club and the ball using the radar sensing data,
generate a swing trajectory area for indicating the swing trajectory of the golf club from the radar sensing data,
set the impact position at the specified impact time point on the swing trajectory area,
