As shown in FIG. 3, a lawn carpet 52 is laid on a part of the floor so that the golf ball 53 can be hung on the game type striking booth 50. The golf ball 53 is placed on the lawn carpet 52 by a golf ball discharging device (not shown).

As shown in FIG. 4, the game-type striking booth 50 is opened to the field side so that the hit golf ball can fly into the field, and has a rectangular parallelepiped shape as a whole. On the open field side, a photo sensor frame 60 is installed on the wall surface so as to track the passing position of the golf ball 53 flying in the field.

FIG. 5 is an enlarged plan view of the game-type strike booth 50 according to the present invention in the golf course shown in FIG. As shown in FIG. 5, a plurality of ultrasonic sensors 56 are installed in the vicinity of the golf ball 53. The ultrasonic sensors 56 are provided on a side surface or a front surface of the golf ball 53 in a direction in which the golf ball 53 flows, and measure the amount and speed of rotation of the golf ball 53.

The golf ball 53 can be rotated left and right according to the hit, and the rotational speed is also changed. The ultrasonic signal received at the ultrasonic receiving unit 58 is compared with the signal stored in the ultrasonic signal DB about the rotational direction and the rotational speed at the measuring point to determine the rotational speed and direction.

The ultrasonic sensor 56 can measure not only the motion of the ball but also the motion of the golf ball to measure the speed and hit points of the golf ball.

The bottom surface of the impact booth 50 is photographed on the ceiling of the game type impact booth 50 to measure the position of the golf ball 53 and the impact time to determine the position of the golf ball 53 A camera module 55 capable of obtaining information can be installed.

The laser point allows the light to be accurately transmitted to the light receiving sensor even in the bright outdoor environment of the outdoor golf driving range through the condensation of the laser.

As shown in FIG. 10, the ultrasonic waves reflected from the golf ball are analyzed to fix the golf ball to the motor so that the rotation speed and direction of the golf ball can be recognized. Then, the rotation speed and direction And stores the waveform of the reflected ultrasonic wave to convert it into a DB. As shown in FIG. 7, when the golf ball passes through the ultrasonic analysis region, ultrasonic waves are reflected at respective positions according to time, and the rotation speed and direction can be known by comparing with the data waveforms according to the positions stored in the DB . The measured values are averaged to measure the number of revolutions and direction.

Accurate drop points can be calculated by reflecting the rotational speed and rotational direction data. For example, the shot position and time of a golf ball are measured with a camera module, and the coordinates and the passage time in the sensor frame are measured. The difference between the calculated drop point and the actual drop point based on the absence of rotation After storing the error by the error of the number of revolutions, the drop point is predicted by correcting the error according to the specific rotation number and the rotation direction to the calculated value based on the non-rotation number.
