Description

Golf information providing system using drone and smart phone

The present invention relates to a golf information providing system, and more specifically, using a drone to shoot a player's swing motion, as well as the distance and the remaining distance, the current position of the ball, and information required for play such as terrain features in each hole in real time. As it relates to a golf information providing system using a drone and a smartphone, which is transmitted to the golfer's smartphone.

Recently, as the income level has improved and the five-day work week has been settled, leisure time has increased and the number of golfers and golf courses has increased as the population enjoying golf has increased. If you start playing golf and go to a real golf course after a lot of practice, then the golf course is wide and there are many real variables, so it is difficult to score as you think, and unlike professional golfers, amateur golfers who enjoy golf as a hobby, even if they go to the same golf course It is true that there are many ups and downs in the score. To summarize these reasons,

First, the golf course is composed of many courses with more than 9 holes, and each hole is classified into par 3, par 4, par 5, etc. according to the different geographical features, that is, the distance from the tee box to the hole. All are different, and terrain features such as bunkers, hazards, and forests are scattered in different forms.

Second, it is not only difficult for the general public to accurately predict a distance of several tens of meters or more, and it is more difficult to predict the distance because the ground in the field is not flat like a playground but has a curvature. Rather, you have to take a shot in a curved terrain, and the distance of the ball is greatly affected by wind direction and wind speed.

Third, it is because it is a precise exercise that requires a keen sense and concentration as compared to other games as well as repeated training for a long time in order to learn the shot sense using various clubs.

Therefore, in order to improve golf skills, it is important to practice shots based on distance sense, and it is important to always recognize and check objective distance data while practicing on various courses of the golf course. In the case of a professional golfer, the golfer can focus on the game by providing the overall course-related information such as the remaining distance and obstacle information with the caddy who is a sports assistant, but in the case of an amateur golfer, one caddy per four people usually accompanies each person. Information that can be limited is limited, and distance measurement based on one's own experience is limited even if it has accuracy. In order to solve this problem, various range finder products have appeared. For example, there are various types such as a range finder using a laser, a range finder using a scope, and a range finder using a GPS (Global Position System).

Patent registration No. 448992, "Portable Golf Information Providing Device Using GPS," provides golf ball flight distance, remaining distance to hole during tee shot, and time information. When a user enters a golf course or tee box, golf course information or It is a technology that displays various golf-related information using a GPS receiver, such as providing hole information. Looking at the above-mentioned patents as well as the competition auxiliary devices that have appeared so far, the distance measuring device using GPS is small and easy to use, but it has a disadvantage that it is difficult to reflect the high and low differences in the course. In addition, the laser range finder using the phase detection of the laser light has an advantage of high accuracy reflected to a target and reflected to a high difference, but has disadvantages of large equipment, inconvenient use, and high price.

In addition, a swing analyzer for analyzing and correcting a golfer's swing has also appeared, which generally provides information by analyzing the club's trajectory and velocity in a three-dimensional space using an accelerometer and a gyro sensor that can be attached to the club. There are many differences between the swing in the driving range and the swing during the actual rounding, but it is difficult to use such equipment during actual rounding using a number of clubs, so it is difficult to expect a practical effect.

As such, various auxiliary equipments have appeared so far, but golfers who have finished playing can not obtain data that can be analyzed by looking at themselves from a third party's perspective by photographing the actual swing motion in the field where they have played. Even when playing memorable things such as Eagle and Buddy, there is a problem that there is no means or method to provide them even if they want to keep a photo or video of their memories.
