Description

Golf distance measuring device and golf distance measuring method {APPARATUS AND METHOD FOR MEASURING DISTANCE FOR GOLF}

The present invention relates to a golf distance measuring device and a golf distance measuring method, and more specifically, to a golf distance measuring device and a golf distance measuring method for providing a target distance between a measurement target and a target to a user located away from the measurement target. It's about.

Golf is played on a course consisting of 18 holes. Starting with a tee shot at each hole, the goal is to put a golf ball into the hole cup on the green.

In such golf, it is very important to accurately determine the distance from the current position of the golf ball to the target point, for example, the hole cup or the flag stuck in the hole cup, in order to select an appropriate golf club every time you make a shot.

Typically, the golfer is provided with the distance from the current position to the target point by the caddy and selects a golf club based on these. However, there is a problem that the distance provided by the caddy may differ from the actual distance depending on the caddy's experience or ability.

In addition, as the cost of using golf courses increases rapidly these days, golf courses where you can choose not to use caddies and no-caddie public golf courses without caddies in the first place are on the rise.

Accordingly, various types of golf distance measuring devices have been developed that measure the distance from the current location to the target point. For example, there are golf distance measuring devices using GPS technology, ultrasonic technology, or laser technology.

A detailed description of the method of using these conventional golf distance measuring devices is as follows. First, take a tee shot and then ride the cart. Then, go to the current location where the golf ball is and measure the distance from the current location of the golf ball to the target point. Afterwards, return to the cart, select a golf club appropriate for the measured distance, then return to the current location and hit the golf ball.

Alternatively, after moving on a cart, roughly estimate the distance, select 2-3 golf clubs that are considered appropriate, and go to the current location of the golf ball. Then, after measuring the distance from the current location to the target point, select the most appropriate golf club among 2-3 golf clubs and take a shot. He then returns with 2-3 golf clubs in his cart.

In this way, when using conventional golf distance measuring devices, you have no choice but to repeatedly travel back and forth from the cart to the current location, or carry 2-3 heavy golf clubs from the cart to the current location.

Accordingly, golfers will rapidly lose their stamina as the hole progresses, and this will become more serious as the distance from the cart to the current location of the golf ball increases. Additionally, there will be a problem where the golf game time is delayed too much.

Hereinafter, the golf distance measuring device and golf distance measuring method according to the present invention will be described in detail with reference to the attached drawings.

Figure 1 schematically shows a golf distance measuring device (1) according to the present invention, and Figure 2 shows the distance between a measurement object (B) and a target object (T) using the golf distance measuring device (1) according to the present invention. 3 shows a method of measuring the distance between a plurality of measurement objects (B1, B2, B3) and a target object (T) using the golf distance measuring device (1) according to the present invention. .

First, referring to Figures 1 and 2, the golf distance measuring device (1) according to the present invention provides a distance between the measurement object (B) and the target (T) to a user (M), a golfer, located away from the measurement object (B). Provides attack range. For example, the measurement object (B) may be a golf ball, and the target object (T) may be the target point to be sent with a shot or the flag of the hole cup.

This golf distance measuring device (1) includes a distance measuring unit (10), an angle measuring unit (20), and a data calculating unit (40).

The distance measuring unit 10 is configured to measure the target distance (MT) from the user (M) to the target object (T) and the measurement object distance (MB) from the user (M) to the measurement object (B). To this end, the distance measuring unit 10 may include various sensors such as a GPS sensor or a laser sensor, but preferably includes a laser sensor that does not require an absolute position, and measures the straight-line distance using the transmission and reception time of the laser. Additionally, a corrected distance reflecting the inclination angle described later may be used in this straight line distance.

And, the included angle measuring unit 20 is configured to measure the included angle (a) between the target distance (MT) and the measurement target distance (MB) centered on the user (M). To this end, the angle measuring unit 20 may include various sensors such as a gyro sensor or a geomagnetic sensor. For example, in the case of a gyro sensor, the angle between angles (a) is measured by accumulating angles, which are information about left and right movement.

In addition, the data calculation unit 40 uses trigonometry to determine the distance (BT) between the measurement object (B) and the target object (T) from the target object distance (MT), the measurement object distance (MB), and the included angle (a). ) is configured to calculate. Specifically, Equation 1 using trigonometry is as follows.

...Equation 1

An example of actually using the golf distance measuring device 1 is described as follows. After a golfer hits a tee shot, he or she rides a cart to a location close to the golf ball. In addition, at a position near the cart where the flag on the golf ball and hole cup is visible, the flag is first taken to measure the distance between the flag and the flag, and then the golf ball is taken while rotating left and right to accumulate and measure the angle between the two. It performs the function of measuring the angle between itself and the distance between itself and the golf ball. From these measured distances and included angles, the distance between the golf ball and the flag is provided.

According to this golf distance measuring device (1), it is not necessary to measure the distance from the point where the golf ball is located to the flag, that is, the distance between the golf ball and the flag is accurately measured even at a location away from the golf ball without any location restrictions. can do.

Accordingly, the golfer does not need to unnecessarily travel back and forth between the cart and the golf ball with heavy golf clubs as in the prior art. In the example above, the golfer can measure the distance from the golf ball to the flag near the cart and select only one golf club that is suitable. Therefore, the golfer's physical strength is maintained well, making it easier for him to demonstrate his skills, and he has more playing time, so he can enjoy golf more.

Referring to FIG. 3, using this golf distance measuring device (1), when there are multiple measurement targets, that is, in addition to the user's golf ball (B1), a flag is also flagged for the golf balls (B2, B3) of accompanying golfers. Each distance to (T) can be measured.

To this end, the distance measuring unit 10 measures the target distance (MT) and a plurality of measurement target distances (MB1, MB2, and MB3). For example, the distance measuring unit 10 measures a plurality of measurement target distances MB1, MB2, and MB3 after measuring the target distance MT. At this time, the target distance (MT) and the plurality of measurement target distances (MB1, MB2, MB3) can be measured using the method described above.

And, the included angle measuring unit 20 measures a plurality of included angles (a1, a2, and a3). For example, the included angle measuring unit 20 measures each of a plurality of included angles when measuring each of a plurality of measurement target distances. At this time, the plurality of included angles (a1, a2, a3) can be measured by adding the method below to the method described above.

Specifically, using a gyro sensor, the angle of inclusion is calculated using the point of time at which the target distance (MT) is measured as a reference point, and the rotation angles from the reference point to the present (up to the golf balls of accompanying golfers), that is, the angles of inclusion. (a1, a2, a3) is obtained using Equation 2 below.

... 수학식 2

...Equation 2

At this time, dt is unit time, and the rotation angle is angular velocity x time.

Preferably, starting from the reference point for measuring the target distance (MT), the included angle is calculated, and the included angles (a1, a2, a3) are continuously measured according to the angular velocity accumulation with a gyro sensor, and more preferably, the included angle is measured from the reference point. Measure the angle between the golf balls closest to you.

However, it is okay to start with the reference point at which one of the plurality of measurement target distances (MB1, MB2, MB3) is measured. In this case, it may be necessary to differentiate between measuring the target distance (MT) and measuring multiple measurement target distances (MB1, MB2, and MB3).

On the other hand, if the measurement time is long, the error value increases, but since the time from measuring the target distance (MT) to calculating the angle between the golf balls of accompanying golfers is a short time, approximately less than 1 minute, the error value is There is no need to consider it. Additionally, even if the golf balls B1, B2, and B3 are measured after the gyro sensor changes left/right and moves up/down, there is no problem in calculating the angle between rotations.

An example of actually using the golf distance measuring device 1 is described as follows. The golfer (M) carrying this golf distance measuring device (1) first takes a flag (T) to perform the function of measuring the distance (MT) between himself and the flag (T), and then rotates left and right to measure the distance (MT) between himself and the flag (T). It performs the function of measuring the included angles (a1, a2, a3) and the distances between itself and the golf balls (MB1, MB2, MB3) by taking a plurality of golf balls while cumulatively measuring each of the plurality of included angles. From the distances and angles measured in this way, the distances (B1T, B2T, B3T) between the golf balls (B1, B2, B3) and the flag (T) calculated by the data calculation unit 40 are provided.

According to this golf distance measuring device 1, it is possible to measure the distances from the golf balls of not only oneself but also of acquaintances playing together to the flag at once. This golf distance measuring device (1) can be used by caddies in addition to golfers to quickly and accurately provide distance information for golfers. Accordingly, the physical strength of all golfers will be well maintained and there will be more playing time.

Referring again to FIG. 1, this golf distance measuring device 1 transmits the distance between the measurement object and the target for a third party other than the user (M) to a separate receiving device (not shown) owned by the third party. It further includes a data communication unit 50. In this case, third parties refer to people including accompanying golfers who have agreed to share information.

When the user and accompanying golfers are close together, the user can measure the distance and communicate it verbally to the accompanying golfers, but there are times when it is difficult to communicate verbally when the user and accompanying golfers are separated.

In this case, the golf distance measuring device 1 automatically or manually transmits the distance of the accompanying golfers measured by the user to a separate receiving device carried by the accompanying golfers through the data communication unit 50 to provide the distance. can do.

For example, the separate receiving device may be a golf distance measuring device that is the same as the main golf distance measuring device, a separate receiver, a smartphone, or a specific device such as a cart control board. This golf distance measuring device and a separate receiver can also be commercialized as a set.

Figure 4 shows a method of measuring the height (h) between the measurement object (B) and the target object (T) using the golf distance measuring device (1) according to the present invention.

This golf distance measuring device (1) measures the target inclination angle (b1) between the target distance (MT) and the horizontal plane (O) and the measurement target inclination angle (b2) between the measurement target distance (MB) and the horizontal surface (O). It is configured to further include an inclination angle measuring unit 30. To this end, the tilt angle measuring unit 30 may include various sensors such as an acceleration sensor.

The data calculation unit 40 uses trigonometry to determine the measurement object (B) and the target object ( The height (h) between T) is additionally calculated. The height (h) between the measurement object (B) and the target object (T) is obtained using the following equation 3.

... 수학식 3

...Equation 3

At this time, h1 is the height between the target object (T) and the horizontal surface (O), and h2 is the height between the measurement object (B) and the horizontal surface (O).

This height (h) can be calculated when measuring the target distance (MT) and the measurement target distance (MB). If there are multiple measurement targets, the target distance (MT) and each measurement target distance (MB1, MB2) can be calculated. , MB3) can be calculated when measuring.

The golf distance measuring device (1) according to the present invention can provide a practical target distance by considering the height (h) of the distance (BT) between the measurement object (B) and the target object (T).

It may further include a data storage unit 60 that stores information such as distance.

Next, Figure 5 shows the distance and height between the measurement object and the target object in three dimensions using the golf distance measuring device according to the present invention. Because it is displayed in three dimensions, it can indicate height and height. That is, Figure 5 is a combined representation of Figures 2 to 4, and shows the relationship between the user, target object, and measurement object in three dimensions on X, Y, and Z.

In detail, Figure 5 schematically illustrates the process of measuring the target object, measuring the golf ball of the first accompanying golfer, and measuring the golf ball of the second accompanying golfer in a three-dimensional state. At this time, the straight line represents the measurement of the distance, and the sequential progression with the dotted line (see (1) to (4) shown in Figure 5) means that the gyro sensor tracks the movement in three dimensions to obtain the included angle, which is the final changed angle. indicates.

Figure 6 shows a block diagram showing the golf distance measuring method (2) according to the present invention. The parts described in this golf distance measuring device (1) are omitted to avoid duplication.

This golf distance measurement method (2) provides the target distance between the measurement object (M) and the target object (T) to the user (M) located away from the measurement object (B), including a distance measurement step (S10); It consists of an angle measurement step (S20) and a data calculation step (S40).

The distance measurement step (S10) measures the target distance (MT) from the user (M) to the target object (T) and the measurement object distance (MB) from the user (M) to the measurement object (B).

And, the included angle measurement step (S20) measures the included angle (a) between the target distance (MT) and the measurement target distance (MB) centered on the user (M).

In addition, the data calculation step (S40) uses trigonometry to calculate the distance between the measurement object (B) and the target object (T) from the target object distance (MT), the measurement object distance (MB), and the included angle (a). do.

When there are multiple measurement objects, the distance measurement step (S10) includes measuring the target object distance (MT) and a plurality of measurement object distances (MB1, MB2, and MB3), and the angle measurement step (S20) includes measuring a plurality of target distances (MT). Includes measuring the included angles (a1, a2, a3).

For example, the distance measurement step (S10) includes measuring a plurality of measurement object distances (MB1, MB2, and MB3) after measuring the target distance (MT), and the included angle measurement step (S20) includes measuring a plurality of measurement target distances (MB1, MB2, and MB3). When measuring each of the measurement target distances (MB1, MB2, and MB3), it includes measuring each of a plurality of included angles (a1, a2, and a3).

In this golf distance measurement method (2), the above steps do not necessarily have to be performed sequentially according to number. For example, it is preferable that the distance measurement step (S10), the included angle measurement step (S20), and the inclination angle measurement step (S30) are measured simultaneously.

Next, Figure 7 shows an actual example of the golf distance measuring device according to the present invention, Figure 8 shows a first method of using the actual example of Figure 7, and Figure 9 shows a second example of the actual example of Figure 7. Indicates how to use.

First, referring to FIG. 7, the configuration of the display unit 100 of the actual golf distance measuring device includes displaying the measurement target (target object, measurement object) 110, displaying the height measurement mode 120, and displaying the measurement target. It consists of displaying distance (130) and displaying information (140) according to elevation when measuring height.

A separate icon 150 for mate mode (distance measurement for a third party) is configured to inform the user that the distance is being measured for a third party, and the corresponding distance display is set to normal mode (distance measurement for the user). Displayed differently.

The actual method of using this golf distance measuring device includes, for example, a first method of using the mate mode separately and a second method of using the mate mode after measuring the user's distance in the general mode.

Specifically, according to the first method of use, the mate mode is entered using a separately designated button or a designated action of the golf distance measuring device. To indicate the entered mate mode, the icon 150 is activated as shown in (a) of FIG. 8, and one side 152 of the icon blinks to first measure the target object.

When the measurement of the target object is completed, the distance 130 between the user and the target object is displayed as shown in (b) of FIG. 8, and the other side 154 of the icon blinks, indicating a third party (accompanying golfer). Make sure measurements are made.

When the measurement of the third party is completed, as shown in (c) of FIG. 8, the distance 132 between the third party and the target object, the distance 130 between the user and the target object, and the distance between the user and the target object are displayed on the display unit 100. The distance 134 between the third parties is displayed.

Subsequently, in order to measure the distance between another third party's golf ball and the target, continuous measurement is possible after setting a separate M mode. At this time, M mode can be set in advance or during operation.

As shown in (d) of FIG. 8, the other side 154 of the icon blinks to measure the distance 132' of another third party, and after measurement of the other third party is made, the display unit 100 The distance between another third party and the target (132'), the distance between the user and the target (130), and the distance between the user and the third party (134') are displayed. And, as shown in (e) of FIG. 8, the distances 130, 132", and 134" can be measured continuously for several third parties.

And, according to the second method of use, the results are displayed when the target is generally measured, as shown in (a) of FIG. 9. Of course, this may vary depending on the manufacturer.

This actual golf distance measuring device uses slope mode and pin catcher mode. Slope mode is a function that provides a correction distance that reflects the difference in height of the target target, and is generally calculated by using an acceleration sensor to calculate the slope angle between the measurement position and the target target. Pin catcher mode is a function that measures the distance by detecting the target target (flag) at the closest distance when you scan the target target (flag) you want to measure from left to right while pressing the measurement button.

The display unit 100 displays the distance to the target target (corrected distance) 130, altitude information between the target target and the user (142), and the straight-line distance (uncorrected distance) 144 between the user and the target target. .

In order to measure the distance 132 between a third party and the target object after first measuring the target object at my location as a user, use a specific function button (or mode button) to measure the distance for the third party. As shown in (b) of FIG. 9, an icon 150 for measuring the distance of a third party appears, and the right side 154 of the icon blinks to measure the distance of a third party.

When the distance 132 between the third party and the target is measured, the respective distances 130, 132, and 134 are displayed as shown in (c) of FIG. 9. When entering the mode for continuously measuring the distance of another third party, the right side 154 of the icon 150 blinks again, and when the distance 132' of another third party is measured, each as shown in (d) of FIG. Distances of (130, 132', 134') are displayed. In this way, continuous measurement is possible.
