1. A method of a golf analysis device including an internal memory, a camera unit, a sensor unit, a communication unit and a remote control module detachably coupled to the golf analysis device, the method comprising:
generating, using the sensor unit, tracking data of a golf club moving by a user's swing motion and a golf ball hit by the user's swing motion;
generating a swing analysis value of a user by analyzing the tracking data;
transmitting, using the communication unit, the swing analysis value to a user terminal and to receive calibration information on the swing analysis value from the user terminal when the swing analysis value is determined by the user to be off by the calibration information, wherein the calibration information is input by the user by modifying a trajectory of the golf ball hit by the user's swing motion which is subjected to an image processing and displayed on a touch screen of the user terminal; and
transmitting, using the remote control module, a request for providing a distance information on a remaining distance to a hole cup through the communication unit in response to an input by the user,
wherein a calibrated swing analysis value is generated based on the tracking data generated by the sensor unit and the calibration information,
wherein a distance between the golf analysis device and the hole cup is calculated based on a location information of the golf analysis device and a location information of the hole cup in response to a receipt of the request for providing the distance from the remote control module through the communication unit,
wherein a user identification (ID) of the user is received from the user terminal via the communication unit in response to a selection of the user ID from the user terminal,
wherein the tracking data of the golf club moving by the user's swing motion and the golf ball hit by the user's swing motion, the calibration information of the swing analysis value, and the calibrated swing analysis value are stored in the internal memory,
wherein the tracking data of the golf club moving by the user's swing motion from the internal memory is searched for when the user performs a swing motion without hitting a golf ball and when a newly acquired tracking data of the swing motion without hitting the golf ball has a similar data pattern as the tracking data of the golf club moving by the user's swing motion, and the calibrated swing analysis value is outputted based on the tracking data and the calibration information stored in the internal memory, and
wherein the user's swing motion is divided into an empty swing motion and a ball hitting swing motion, the ball hitting swing motion is detected when a noise level around a tee box where the user's swing motion is performed is rapidly lowered below a threshold level, and the camera unit is activated to photograph the user's swing motion when the ball hitting swing motion is detected.
