Among games, sports-themed games are literally enjoyed on a computer, and game users have not been able to actually apply them to sports based on the game experience. Instead, they simply learned the functions of keyboard and mouse operations. However, the virtual reality golf simulation system of the present invention has a simulation mode with an element of interest as a game, a preview mode with an element as a simulation, a tutorial mode, and a panoramic view mode.

You can enjoy the learning effect naturally by using the preview mode, the tutorial mode, and the panama view mode to obtain the golf course information while playing the golf game in the simulation mode. In addition, based on the hole topographic map, the distance from the tee shot position to the hole, the measurement of your own distance, and the sufficient terrain through the video of the actual golf course, it is possible to use the information to play even if you actually go to the golf course. .

The virtual reality golf simulation system is different from games aimed at recreational interests only, or for any other golf education product. For example, golfers use a variety of learning methods to improve their skills, to change golf clubs, to buy and view books, to purchase famous golf course videotapes, and to record several times without recording any good games. However, there is a problem that these learning methods are used in a state in which an environmental element such as a golf course, which is an important element that is indispensable in golf, is excluded.

In fact, in addition to the skill and sense of golfers, the external element of the golf course is very important unlike other sports. Golf is important information for golfers, such as the distance of each hole in the golf course, hole topography, the location of obstacles. In this regard, simply the scorecard or hole topography, which is the hole information of the golf course, cannot convey the information of the golf course. However, since the present invention is golf that is made in virtual reality, the terrain information of the golf course can be acquired from the third party's point of view, or the golf can be directly played as a virtual player, so that the simulation system can exhibit sufficient value.

The present invention can be variously modified and can take various forms and only the specific embodiments thereof are described in the detailed description of the invention. It is to be understood, however, that the present invention is not limited to the specific forms mentioned in the detailed description of the invention, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood to do.

The advantages of the present invention are as follows:

First, there is no limit to the number of users using the golf course. That is, the system of the present invention is made in virtual reality, not the actual golf course, anyone can enjoy golf and get information without limiting the number of users.

Second, the golf learning effect can be obtained through the present invention. The present invention is not only enjoyed as a golf game, but also the course topography, hole shape, distance, etc. of the golf course is reproduced through three-dimensional modeling, and is useful for acquiring information through accurate numerical data.

Third, it is user-centric. In other words, the topographic map of the actual golf course is made into 3D data so that you can enjoy golf on a computer. And with the actual information of the golf course, users can look around the golf course, check the shape as if they are looking down from above the hole, and measure the shot distance that fits their own distance. It is possible.
