Abstract

It is an object of the present invention to provide a hybrid golf system, a control method of a mobile terminal used to the same and a method for locating a golf ball at a ball position on a field using a user's mobile terminal in the hybrid golf system that allows the user to find a golf ball position on an actual field corresponding to a virtual ball position on a virtual golf course using the user's mobile terminal without additional devices for pointing the golf ball position.

First claim

The invention claimed is:

1. A method for locating a golf ball at a ball position on a field using a user's mobile terminal in a hybrid golf system including a field provided for the user to play golf and a screen golf module provided on one side of the field to play golf on a virtual golf course, the method comprising:
transmitting by a simulator in the screen golf module, information on the user's ball position on the virtual golf course according to the golf play in the screen golf module to the user's mobile terminal;
displaying a ball position indication indicating the ball position on the field corresponding to the user's ball position on the virtual golf course on a augmented reality image executed by the user's mobile terminal; and
locating an object of the golf ball on the ball position indication on the augmented reality image of the user's mobile terminal so that a ball ready on the field occurs, indicating that the golf ball is located at the user's ball position on the field.

2. The method according to claim 1 , wherein the transmitting information to the user's mobile terminal includes transmitting ball position information on the virtual golf course of each of a plurality of users to each of the mobile terminals of the plurality of the users, and
wherein the displaying the ball position on the field includes:
calculating by each of the mobile terminals, ball positions on the field corresponding to each of the users' ball positions on the virtual golf course;
providing by each of the users' mobile terminals, a shot guide to each of the users when each of the users becomes a shot order of each user; and
displaying a ball position indication indicating the user's ball position on the field on the augmented reality image of the mobile terminal provided the shot guide.

3. The method according to claim 1 , wherein the displaying the ball position on the field includes:
calculating by the mobile terminals, the ball position on the field corresponding to the users' ball positions on the virtual golf course; and
displaying a ball position indication indicating the ball position on the field on the augmented reality image executed by the mobile terminal using position information calculated by a GPS module of the mobile terminal and information of the ball position on the field.

4. The method according to claim 1 , wherein the displaying the ball position on the field includes displaying the ball position indication on the augmented reality image larger as the distance between the ball position on the field and the mobile terminal's position is further, as the user holds the mobile terminal and approaches the ball position on the field, the ball position indication on the augmented reality image is gradually reduced.

5. The method according to claim 1 , wherein the locating an object of the golf ball on the ball position indication includes:
capturing the golf ball placed at an arbitrary position on the field in an angle of view of a camera of the mobile terminal in the state of displaying the ball position indication indicating the ball position on the field on the augmented reality of the mobile terminal;
recognizing an object of the captured golf ball by the mobile terminal;
detecting by the mobile terminal, whether the golf ball object is located on the ball position indication in the augmented reality image as the user moves the golf ball; and
occurring a ball ready on the field when the golf ball object is located on the ball position indication in the augmented reality image.

6. A control method of a mobile terminal used to a hybrid golf system including a field provided for the user to play golf and a screen golf module provided on one side of the field to play golf on a virtual golf course, the control method comprising:
receiving a user's ball position on a virtual golf course according to the user's golf play in the screen golf module;
calculating a ball position on the field corresponding to the received ball position on the virtual golf course;
executing an augmented reality image and displaying a ball position indication indicating the ball position on the field in the augmented reality image; and
recognizing a golf ball on the field as an object of the golf ball, and occurring a ball ready on the field that determines that the golf ball is located on the ball position on the field when the recognized golf ball object is located on the ball position indication displayed in the augmented reality image.

7. The control method according to claim 6 , wherein the displaying the ball position indication in the augmented reality image includes:
providing a shot guide when the user owned the mobile terminal becomes a shot order; and
displaying the ball position indication indicating the ball position on the field on the augmented reality image executed by the mobile terminal using position information calculated by a GPS module of the mobile terminal and information of the ball position on the field.

8. A hybrid golf system comprising:
a screen golf module provided on one side of a field where a user can play golf and allowing the user to play golf on a virtual golf course;
a simulator provided in the screen golf module and implementing an image of a virtual golf simulation on the virtual golf course; and
a mobile terminal that is configured to:
receive a user's ball position on the virtual golf course according to the user's golf play in the screen golf module,
calculate a ball position on the field corresponding to the received ball position on the virtual golf course,
execute an augmented reality image and displaying a ball position indication indicating the ball position on the field in the augmented reality image,
recognize a golf ball on the field as an object of the golf ball, and
occur a ball ready on the field that determines that the golf ball is located on the ball position on the field when the recognized golf ball object is located on the ball position indication displayed in the augmented reality image.
