Abstract:
1. A system for correcting a golf swing using the Internet, comprising: photographing means for photographing a golf swing of a golfer and outputting corresponding data; image processing means for receiving data output from the photographing means, image-processing the data and outputting corresponding image data; weight center detecting means for detecting movement of a center of weight during a golf swing and outputting a corresponding detection signal; club head detecting means for detecting an angle and a speed of a club head and outputting a corresponding detection signal; signal processing means for receiving the detection signals output from the weight center detecting means and the club head detecting means, computing the movement of the center of weight and the angle and speed of the club head within an impact zone and outputting corresponding computation data; control means for receiving the image data and the computation data output from the image processing means and the signal processing means, respectively, synchronizing the image data and the computation data and outputting moving picture data; display means situated in front of a golf ball positioned in front of the golfer for displaying a currently performed golf swing, and receiving and displaying the moving picture data output from the control means; practice center communication means for receiving and transmitting the moving picture data output from the control means, receiving and transmitting a request for provision of golf swing correcting data and a request for provision of moving pictures obtained during golf swing practice in response to a key manipulation of the golfer, and receiving and displaying golf swing correcting data and moving pictures obtained during golf swing practice; personal communication means for receiving and transmitting a request for provision of golf swing correcting data and a request for provision of moving pictures obtained during golf swing practice in response to a key manipulation of the golfer, and receiving and displaying golf swing correcting data and moving pictures obtained during golf swing practice; a Web server for receiving the request output from the practice center communication means or personal communication means, outputting a corresponding control signal, and outputting golf swing correcting data or moving picture data to the practice center communication means or personal communication means; a three-dimensional data generating server for receiving the control signal output from the Web server, generating a wire frame, that is, three-dimensional posture data of the golfer, comparing this generated wire frame with a stored reference wire frame, and outputting golf swing correcting data, wherein generating the wire frame includes: a golf swing managing server for receiving the control signal output from the Web server, storing moving picture data of golf swing practice of the golfer, and outputting the stored moving picture data; and a mail server for receiving the control signal output from the Web server, and outputting various golf information to the practice center communication means or personal communication means via e-mail.
