Golf is a sport in which golf balls are hit and put into holes. The golfer determines the target point in consideration of the current position of the golf ball and the position of the hole, and selects an appropriate golf club and strikes the golf ball to move the golf ball to the target point.

First, the golfer refers to the distance marking fixtures installed along the pins and fairways set up in the hole to determine the location of the hole and the distance from the current position to the hole. When the golfer grasps the distance from the current position to the hole, the golfer determines a target point to which the golf ball is to be moved. However, because the location of the hall changes from time to time, the fixture may not reflect the location of the hall from time to time. Therefore, it is difficult for the golfer to accurately determine the distance from the current position to the hole, so that the target point may be an inappropriate position for putting the golf ball into the hole.

Also, even if the optimal target point is determined, the golfer cannot accurately determine the distance from the current position to the target point. Therefore, the golf club selected by the golfer in consideration of the distance from the current position to the target point may be an inappropriate golf club to move the golf ball to the target point.

In this case, the controller 180 may further display the horizontal distance value 603 from the current position to the target on the display unit 151a.

The controller 180 calculates points corresponding to the horizontal distances of interest (S112).

The controller 180 may calculate points spaced apart from the current position by a preset horizontal distance. For example, the controller 180 may calculate points spaced apart by a horizontal distance of 10 yards from the current position. The controller 180 may calculate points 10 yards apart, points 20 yards apart, points 30 yards away from the current location, and the like. The preset horizontal distance is not limited to 10 yards, but may be changed to 10 meters, 20 yards, or the like, but is not limited thereto.

The horizontal distance of interest includes a horizontal distance adjacent to the horizontal distance to the target among the preset horizontal distances. For example, if the horizontal distance value to the target is calculated to be 153 yards, the horizontal distances of interest include 130 yards, 140 yards, 150 yards, 160 yards, 170 yards, and the like. Horizontal distances of interest include distances ranging from 70% to 130% of the horizontal distance value. The above range may be changed to 80% to 120%, 90% to 130%, and the like, but is not limited thereto.

The controller 180 may calculate points corresponding to the horizontal distance of interest on the map image using the map image information of the course and the accumulation information of the map image. Reference is also made to FIG. 7 in this regard.

As illustrated in FIG. 7, the controller 180 may determine a point 700 corresponding to the current location on the map image 1510. The controller 180 may calculate lengths D1a, D1b, and D1c corresponding to the horizontal distances of interest using the horizontal distances of interest and the accumulated information of the map image 1510. And the controller 180 centers the points 700 on the horizontal distances of interest on the map image with the coordinates (or functions representing the arcs) of the circular arcs whose lengths of the radius are the lengths D1a, D1b, and D1c. It can be calculated as the corresponding points.

Then, as shown in FIG. 6, the controller 180 displays the course map image on which the

indicator lines

602a, 602b, and 602c indicating the horizontal distances of interest are displayed on the display unit 151a (S114). In this case, the controller 180 may further display the values of the horizontal distances of interest on the display unit 151a corresponding to the

indicator lines

602a, 602b, and 602c.

The

leader lines

602a, 602b, and 602c may be displayed in a different form from the leader line 601. For example, the leader line 601 may be displayed as a thicker line than the

leader lines

602a, 602b, and 602c. In addition, the color of the leader line 601 may be different from the color of the

leader lines

602a, 602b, and 602c.

Optionally, the azimuth sensor 114 measures the azimuth angle in the direction in which the distance measuring device 100 faces (S116).

Then, the controller 180 displays the course map image on which the object 600 corresponding to the current location and the virtual line 604 corresponding to the direction in which the distance measuring device 100 is directed (S118). .

When the coordinates of the current position measured by the position acquisition sensor 112 change, the controller 180 moves and displays the object 600 on the course map corresponding to the changed coordinates. When the horizontal distance from the azimuth sensor 114 to the target measured is changed, the controller 180 changes and displays the indicator line 601 on the course map image corresponding to the horizontal distance to the target.

Next, with reference to FIGS. 8-10, the control method of the distance measuring device 100 which concerns on 2nd Example is demonstrated.

FIG. 8 is a flowchart illustrating a control method of the distance measuring apparatus 100 according to the second embodiment, and FIG. 9 illustrates a screen displayed on the display unit 151a of the distance measuring apparatus 100 according to the control method of FIG. 8. Drawing.

First, the position acquisition sensor 112 acquires the current position (S200). The position acquisition sensor 112 may acquire the coordinates of the current position of the distance measuring device 100.

The controller 180 reads course map information corresponding to the coordinates of the current position from the memory 160 (S202). The course map information includes position coordinate information of each point divided by a predetermined unit (for example, a pixel unit, a predetermined length (1 yard or 1 meter) unit, GPS coordinate unit, etc.) in the golf course. The location coordinate information may include altitude information of each point. In addition, the course map information may include map image information of the course, accumulation information of the map image, location coordinate information corresponding to reference points of the map image, and the like.

Next, the controller 180 calculates points corresponding to the attack distances of interest (S112). Regarding the attack distance, a description will be given with reference to FIG. 10.

One point 200 in the course has a corresponding altitude value. The controller 180 may calculate the horizontal distance L0 and the altitude difference h01 between the two points using the coordinates of the current point and the coordinates of the one point 200.

Then, the controller 180 may calculate the attack distance X0 to the target 200 by using Equation 2 below using the horizontal distance L0 and the altitude difference h01.

Here, X0 is the attack distance, L0 is the horizontal distance from the distance measuring device 100 to the target 200, and h02 is the height from the golf ball 10 to the distance measuring device 100. h02 may be any value that can be set by user input. Alternatively, h02 may be a value obtained by measuring a vertical distance from the ground using the distance sensor 113. When the straight line distance d0 is equal to or greater than a predetermined distance value (for example, 150m, etc.), the value of h02 may be ignored in the equations.

At this time, there is a relationship as shown in Equation 3 below between the attack distance X0 and the expected landing angle a02 of the golf ball 10.

That is, the attack distance X0 and the expected landing angle a02 may be expressed as a function as shown in Equation 3, and the shape of the function is not limited to the linear function, the secondary function, and the like. For example, the attack distance X0 and the expected landing angle a02 may be expressed as a linear function, as shown in Equation 4 below.

Here, i and j are constant values, values that can be selected by the user or by the controller 180. For example, if the user is male, i may be selected as 0.11, j is 67, and if the user is female, i may be selected as 0.11 and j is 60. However, the i and j values of the present invention are not limited thereto. Alternatively, the attack distance X0 and the expected landing angle a02 may also be expressed as a quadratic function, as shown in Equation 5 below.

Here, l, m, and n are constant values, which are values that can be selected by the user or by the controller 180.

In addition, the attack distance X0 may be calculated using an angle a1 and a horizontal distance L0 formed by a line connecting the current point and the one point 200 with the ground, but are not limited thereto.

Using the above method, the controller 180 can calculate points (or a function of points) at which the attack distance X0 satisfies the attack distance value of interest.

Then, as shown in FIG. 9, the controller 180 displays the course map image on which the object 900 corresponding to the current position and the leader lines 901, 901b, and 901c indicating the target distances of interest are displayed. (S206). In this case, the controller 180 may further display the values of the target distances of interest on the display unit 151a corresponding to the indicator lines 901, 901b, and 901c. These

leaders

901, 901b, and 901c may have a free curve shape.

The distance measuring sensor 111 measures a straight line distance from the distance measuring device 100 to the target 200 (S208), and the tilt sensor 113 measures the tilt angle of the distance measuring device 100 (S210). . The order of step S208 and step S210 is not limited to this.

Then, the controller 180 calculates the attack distance to the target by using the measured linear distance and the tilt angle (S212). The controller 180 may calculate the attack distance to the target by using Equations 1 to 5 and Equation 6 below.

Referring to FIG. 10, in relation to the calculation of the attack distance X0, the height h01 from the distance measuring device 100 to the target 200 may be calculated using Equation 6 below.

Here, d0 is a straight line distance to the target 200 (distance to the target 200 measured by the distance measuring sensor 111), a01 is a tilt angle of the distance measuring device 100, h01 is a distance measuring device It is the height (elevation difference) from 100 to the target 200.

The controller 180 calculates a horizontal distance from the distance measuring device 100 to the target 200 through Equation 1, and calculates the height (from the distance measuring device 100 to the target 200 through Equation 6). Altitude difference), and the attack distance may be calculated using Equation 2 and Equation 3.

Then, the controller 180 displays the course map image on which the indicator line 902 indicating the attack distance to the target calculated by the distance measuring apparatus 100 is displayed on the display unit 151a (S214). The leader line 902 may have a free curve shape.

The leader lines 901, 901b, and 901c may be displayed in a different form from the leader line 601. For example, the leader line 902 may be displayed as a thicker line than the leader lines 901, 901b, and 901c. In addition, the color of the leader line 902 may be different from the color of the leader lines 901, 901b, and 901c.

Optionally, the azimuth sensor 114 measures an azimuth angle in the direction in which the distance measuring device 100 faces (S216).

Then, the controller 180 displays a course map image on which the object 600 corresponding to the current location and the virtual line 604 corresponding to the direction in which the distance measuring device 100 is directed (S218). .

When a point of interest such as a hazard, bunker, rough, green, hole, etc. is located in a direction that the distance measuring device 100 faces, the controller 180 may select indicators 905 and 906 indicating the distance to the point of interest and the point of interest. It can be additionally displayed on the course map. In this case, the controller 180 may determine the distance from the current point to the point of interest (for example, the distance from the current position to the point where the hazard, bunker, or green starts along the direction toward which the distance measuring device 100 is directed, and the current position. Distance from the hazard, the bunker, or the end of the green, the distance from the current location to the hole, etc. may be additionally displayed along the direction that the distance measuring device 100 faces.

When the coordinates of the current position measured by the position acquisition sensor 112 change, the controller 180 moves and displays the object 600 on the course map corresponding to the changed coordinates. When the attack distance from the azimuth sensor 114 to the target measured is changed, the controller 180 changes and displays the leader line 902 on the course map image corresponding to the target distance to the target.
