GOLFZON Co., Ltd.

The present invention relates to a golf swing platform linked to a virtual golf course, and may independently drive a swing-stage part and a hitting part of the platform, and the inclination information may be calculated from terrain information of an area corresponding to the swing-stage part and the hitting part of the platform based on a position where a virtual ball is placed on the virtual golf course, and the swing-stage part and the hitting part may be controlled to be driven, respectively.

The present invention is to provide a divided driving swing platform including a plurality of plates divided from the swing platform on which a user can perform a golf swing with a golf club and operated stably by increasing a degree of freedom of movement of each of the divided plates so that each of the divided plates can move in various ways and interference between the divided plates does not occur when each of the divided plates is driven and operated.

Provided are an apparatus and method for sensing a moving ball, which extract a feature portion such as a trademark, a logo, etc. indicated on a ball from consecutive images of a moving ball, acquired by an image acquisition unit embodied by a predetermined camera device, and calculate a spin axis and spin amount of rotation the moving ball based on the feature portion and thus spin of the ball is simply, rapidly, and accurately calculated with low computational load, thereby achieving rapid and stable calculation of the ball in a relatively low performance system. The sensing apparatus includes an image acquisition unit for acquiring consecutive images, an image processing unit for extracting a feature portion from the acquired image, and a spin calculation unit for calculating spin using the extracted feature portion.

The present invention is to provide a method for detecting a golf club and a sensing device using the same, and provides a new method for detecting the golf club from an image captured by the sensing device. The present invention provides a method for accurately analyzing movement characteristics such as bending of a golf club by accurately detecting the shape of the golf club during golf swing by analyzing the shadow of the golf club formed on the floor in the captured image rather than directly detecting the golf club from the captured image.

Disclosed are a virtual golf system, a virtual golf introduction image generation method, and a virtual golf player information calculation method capable of providing a separate introduction image showing two or more users so as to be comparable to each other through record information of a virtual golf game of each of a plurality of users who use the virtual golf system before the plurality of users access the system in order to play the virtual golf game, whereby it is possible to induce users' record competition in the virtual golf game and to provide the users with immersiveness and interest in the game.

The present invention, which has been made in view of prior art problems, relates to a virtual golf simulation processing method capable of providing various simulation image production modes such that, when a user takes a golf shot in a certain situation, a unique simulation image for the golf shot is produced, whereby a user who plays a virtual golf game experiences a more dramatic and dynamic simulation image, and therefore it is possible to induce interest of the user, and a screen golf system using the same.

Disclosed are a device for calculating flight information of a ball and a method of calculating flight information of a ball that are capable of rapidly calculating the motion parameters of a ball and a golf club using an infrared sensing type device or a camera sensing type device and very rapidly calculating spin information of the ball corresponding to the calculated motion parameters with high accuracy through a simple calculation with reference to database type information about the calculated motion parameters, and a computing-device-readable recording medium having the method recorded therein.

The present invention is not a method of directly calculating the rotational characteristics of a ball through frequency analysis of a received signal as in the prior arts, but a method of determining a final spin information by finding the spin information of the moving ball while approaching a ball trajectory predicted in terms of the trajectory of a moving ball using the position coordinate data of the ball to the trend data indicating the trend of the position coordinates of the moving ball. The present invention provides a method of finding the spin in terms of the trajectory of the moving ball, regardless of whether it is possible to check the frequency characteristics of the rotation of the ball from the signal reflected from the moving ball, and thus derives a fairly accurate and uniform spin calculation result.

The present invention provides a method for calculating a swing trajectory of a golf club using radar sensing data capable of calculating a swing trajectory of a golf club therefrom, a radar sensing device using the same, and a recording medium readable by a computing device recording the calculation method, which calculates the position coordinate information of the golf club through the analysis of the radar signal separately from calculating the motion parameters for the ball through the analysis of the radar signal when the golfer hits the ball with the golf club, and effectively calculate the swing trajectory of the golf club from the calculated position coordinate information of the golf club.

Disclosed are a sensing device for calculating information about a golf shot when the user hits a ball using a golf club in order to take a golf practice or play a virtual golf game using a screen golf system and a sensing method thereof, and in particular a sensing device for calculating information about a golf shot taken by a user, wherein, when acquiring and analyzing an image of a user hitting a ball using a golf club, the sensing device is configured to effectively detect the position of a feature point corresponding to the position of the golf club through analysis of the acquired image without attaching a certain characteristic marker to the golf club and to calculate various kinds of physical information about the motion of the golf club according to a golf shot using the feature point, and a sensing method using the same.
