Abstract: The present invention relates to a screen golf device including a virtual game storage unit and a processing unit, wherein the virtual game storage unit stores data for virtual player characters of actual professional golfers and condition data of past golf games played by at least one of the actual professional golfers. When a user strikes a golf ball on a tee box with a golf club on a swing plate, the processing unit derives the trajectory of the golf ball based on golf ball sensing information obtained from a sensing unit sensing the movement of the golf ball, processes the virtual golf game between the virtual player character and the user based on the derived trajectory and the condition data of the past golf game, and displays the progress of the virtual golf game on a screen unit.

Abstract: The present invention relates to a golf plate device having a height adjustment part. The golf plate device having a height adjustment part includes: a frame part; a plate part 200 which is provided on the top of the frame part in a planar rectangular shape; and a height adjustment part which includes a plurality of actuators which are installed on the frame part at regular intervals to allow for individual operation, thereby adjusting the height of the plate part, wherein the plate part is made of a material which is deformable and restorable by elasticity, and in a case in which the height is adjusted by the plurality of actuators, the planar shape of the plate part is varied into a curved surface shape.

Abstract: Disclosed herein is an apparatus for providing golf lessons including: a camera unit configured to photograph images of a golf ball hit by a user with a golf club; a memory configured to store golf lesson data according to ball flight patterns of the golf ball; and a processor for analyzing the images of the golf ball captured by the camera unit to derive the ball flight patterns, reading the golf lesson data according to the ball flight patterns from the memory, and providing the read golf lesson data to the user.
