1. A golf posture measuring mat capable of measuring a speed of a golf club, the golf posture measuring mat comprising:
a sensor unit configured to sense a pressure corresponding to a golf posture of a user and a predetermined trajectory of a head of a golf club;
a control unit configured to analyze the golf posture of the user and a swing speed of the golf club based on a sensed signal of the sensor unit;
a display unit configured to display analysis data analyzed by the control unit; and
a storage unit configured to store the analysis data and reference data,
wherein a plurality of sensors in the sensor unit are arranged one-dimensionally or two-dimensionally on a mat plate,
wherein each of the plurality of sensors includes a single sensor including one among a capacitive pressure sensor, a resistive pressure sensor, and a hybrid pressure sensor, or includes a composite sensor including two or more among the capacitive pressure sensor, the resistive pressure sensor, and the hybrid pressure sensor, and
wherein the control unit is configured to:
determine a tee location by analyzing a location of a golf ball based on the sensed signal of the sensor unit when receiving body information of the user;
determine an address posture by analyzing a pressure center point of the user and a location of the head of the golf club;
estimate a center-of-gravity of the user by reflecting the pressure center point of the user and the received body information of the user;
determine a swing by reflecting a change in a plantar pressure of the user, the pressure center point of the user, and the center-of-gravity of the user corresponding to a change in the golf posture of the user;
determine an impact corresponding to a weight change of the tee location;
calculate the swing speed of the golf club before and after the impact;
analyze the golf posture of the user by comparing a change in the plantar pressure of the user, a change in the pressure center point of the user, and a change in the center-of-gravity of the user corresponding to the change in the golf posture of the user with the reference data; and
control the display unit so as to display the analysis data including the analyzed golf posture of the user and the swing speed of the golf club.
