Abstract

PURPOSE: An apparatus for analyzing a posture and gravity center of a golfer is provided to allow a golfer to check and correct a swing pose by displaying the swing pose and the gravity center of the golfer in a computer monitor. CONSTITUTION: A posture and gravity center analyzing apparatus for a golfer includes two CCD cameras(103,104) and a tripod for mounting the CCD cameras(103,104). The CCD cameras(103,104) photograph front and lateral profiles of the golfer. Electronic scales are mounted under each foot of the golfer in order to measure weight applied to each leg of the golfer. The swing action of the golfer is photographed as 70-frame images and 70 lots of weight data are provided with respect to each leg of the golfer. The gravity center of the golfer is calculated based on the weight data and is displayed on a computer monitor.

Description

Golfer's Posture and Center of Gravity Analysis during Golf Swing {POSTURE AND MASS CENTER OF GOLFER ANALYSIS SYSTEM DURING GOLF SWING}

none

-Accurately photograph the side and back of the swing exerciser on one monitor.

-Accurately determine the starting and end points of the golf swing, save only the necessary image data, and then play it back.

-You should be able to check the swing form change by saving your swing form.

-It should be able to receive and store the input of electronic scale in synchronization with each frame of the swing form.

-The weight signal from each electronic balance should be used to calculate the position of the golfer's center of gravity.

-The calculated golfer's center of gravity should be able to be displayed on the computer monitor along with the recorded swing form image.

The present invention captures the image of the golfer's golf swing with the CCD camera (103,104) and at the same time receives the golfer's weight signal from the electronic scale scaffold (105,106) under the golfer's feet to store the golfer on the general computer monitor 101 This is a system that helps you to check and correct your swing posture by showing the swing's center of gravity and the golfer's center of gravity at each swing.

Unlike the golf swing correctors using the images already presented, the present system simply measures the center of gravity of the golfer according to the swing moment taken in addition to the swing form of the golfer and analyzes two CCD cameras 103 and 104 as tripods. The front and side of the golfer is photographed by dividing, the footrest standing golfer is divided into two and each footrest (105, 106) mounted on the electronic balance to receive the weight of the golfer's left foot and right foot, respectively. The point in time at which the weight is input is when the image of the CCD cameras 103 and 104 is updated, that is, when the NTSC output signal of the general CCD cameras 103 and 104 produces one image at a rate of 30 frames per second. Becomes Therefore, if the golfer's swing motion is composed of 70 frames, the weight data of the golfer's left foot and right foot, respectively, will be 70 as well as the number of images. The center of gravity of the golfer is calculated using the weight data thus obtained, and each time the image is updated on the computer monitor 101, the center of gravity information is displayed as a graph or a numerical value so that the golf swing motion can be analyzed more efficiently.

In addition, in order to measure the center of gravity more finely, as shown in FIG. 2, the four footrests 201, 202, 203, and 204 may be divided, and the electronic scales may be mounted on each footrest to read the golfer's weight.

-You can analyze your own swing posture through the golf swing posture image.

-You can learn how to swing more effectively by checking your swing posture as well as the center of gravity movement.
