Description

Putting auxiliary terminal that provides putting guide based on green information and its control method {PUTTING ASSISTANCE APPARATUS BASED ON GREEN INFORMATION PROVIDING PUTTING GUIDE AND CONTROL METHOD THEREOF}

The present invention relates to a terminal that provides a putting guide to a user through green information analysis.

In general, in golf, a golfer can send a ball to a desired distance and direction only by taking a shot while properly responding to the slope of the ground. In particular, to put the ball into the hole cup on the green, a putter is used. At this time, the ball rolls on the green and is sent to the hole cup, so how to grasp the slope of the green and in which direction and how much force to hit the ball is very important. It is important.

However, it is not so easy for the golfer to determine the inclination angle of the green on his own, so it is often possible to make a putting mistake. In this regard, the term lie, which refers to the inclination of the periphery where the golf ball is landed, is also used. As a technique related to measuring the inclination, the "putter with a level" (Korean Laid-Open Patent Publication 10-2005-0109319) It has been released. The above technology allows the level of inclination and the direction of inclination of the ground to be determined by combining the level with the shaft or club head constituting the putter.

However, the above techniques are used by integrally combining the level with the putter, which has a problem in that the golfer must use only the putter combined with the level when measuring the slope on the green. In the end, given the variety of putters used for each golfer, there is a problem in that each putter uses a putter combined with a level.

In the case of Korean Patent Laid-Open Publication No. 10-2016-0071618 (name of the invention: a method of detecting the green slope of a golf field), a green area is photographed using a camera, and the height and slope of the green are determined through the photographed result. We propose a device and a method to analyze and provide it to the user.

However, in order to determine the height by analyzing the camera image, there is a disadvantage that not only a large amount of computation is required in the image analysis, but also the accuracy remains at a fairly low level despite a large amount of computation.

Therefore, there is a need for research on a device or method capable of analyzing information on the green more accurately and quickly, and guiding putting, rather than simply shooting through a camera.

It is an object of the present invention to solve the above and other problems. Another object is to provide a device capable of extracting more accurate green information even with a lower computational amount.

Thus, it provides a putting auxiliary terminal, characterized in that calculating the height or slope of the green.

The distance measuring unit may include a laser light emitting unit; And a laser light receiving unit, and a distance may be calculated based on a result of the laser irradiated through the laser light receiving unit detected through the laser light receiving unit.

The distance measuring unit may further measure a distance of a point perpendicular to the ground.

It may further include an inclination detector for detecting inclination.

The control unit may calculate the height of the first point based on the first distance to the first point, the second distance to the vertical point, and an inclined angle sensed through the tilt detection unit.

The display unit may further include a display unit, and the controller may control the putting guide screen to be output to the display unit based on the calculated result.

According to another aspect of the present invention to achieve the above or other object, measuring a distance to a predetermined point on the green; And calculating a height or slope of the green based on the measured distance, wherein the measuring of the distance comprises measuring a distance to at least two points, and the calculating comprises: the measured two points It provides a control method of a putting auxiliary terminal, characterized in that the height or slope of the green is calculated based on the distance to.

A display unit 151 is provided on the rear surface of the housing 101 to output and provide information related to the putting guide to the user.

4 is a view showing the structure of the head 103 inside the housing 101 according to an embodiment of the present invention.

The head 103 is not fixed to the housing 101 but is fastened to the body and the gimbal part 110.

The gimbal unit 110 refers to a device that maintains the rotational balance while the head 103 is facing a specific direction. The rotation balance will be described below with reference to FIGS. 5 and 6.

5 to 7 are views showing a state in which the balance of the head 103 is maintained by the gimbal unit 110 according to an embodiment of the present invention.

Referring to FIG. 5, the head 103 is maintained facing a predetermined direction 510. Even if the user rotates the handle 102 left and right clockwise/counterclockwise, the gimbal unit 110 rotates the head 103 in the opposite direction to compensate for the inclination of the head 103 in a predetermined direction ( You can maintain the balance of rotation to look at 510).

That is, when rotation is sensed through the tilt detection unit 141, it operates to rotate in the opposite direction to compensate for the rotation.

5 illustrates only the balance of the first axis when the putting auxiliary terminal 100 is viewed from above, but the balance may also be maintained on the other axis.

6, even if the handle 102 rotates left or right in the front view of the putting auxiliary terminal 100, the inclination of the head 103 may be fixed. That is, in FIG. 6, the balance of the second axis may be maintained.

That is, as shown in FIG. 6, even if the handle 102 rotates left and right, the head 103 may be inclined while maintaining a predetermined angle 601.

Referring to FIG. 7, likewise, even if the handle 102 rotates in a forward and backward direction, the inclination may be fixed while the head 103 maintains a predetermined inclination. The balance maintained in Fig. 7 is the balance about the third axis.

In FIGS. 5 to 7, the balance for each of the first to third axes has been individually described, but the actual gimbal unit 110 may be operated to simultaneously maintain the balance for the first to third axes.

Meanwhile, in the scanning operation to be described later in detail below, the user may manually perform the scan while lifting or lowering the head 103 (manual scan). Therefore, in such a manual scan operation, when the user lifts or lowers the head 103, the balance maintaining operation with respect to the third axis may be released. That is, in an embodiment of the present invention, only the balance maintaining operation for the third axis can be released while the balance maintaining operation for the first and second axes is maintained.

For example, upon receiving a scan start command from a user, the controller 180 controls the gimbal unit 110 to maintain balance for the first and second axes, but release the balance for the third axis. can do.

That is, the gimbal unit 110 as described above fixes the inclination of the head 103 so that more accurate results can be obtained in obtaining green information in the present invention.

8 is a diagram showing the structure of the head 103 according to an embodiment of the present invention. 9 is a diagram illustrating a conceptual diagram for measuring a distance of the distance measuring unit 142 according to an embodiment of the present invention.

Referring to the illustrated drawing, the head 103 may include a camera 121, a laser pointing unit 122, and a distance measuring unit 142.

The distance measuring unit 142 according to the exemplary embodiment of the present invention may be provided to include a laser light emitting unit 501 and a laser light receiving unit 502.

That is, when the laser irradiated through the laser light emitting unit 501 is received again through the laser light receiving unit 502, the distance to the target point is measured based on the received result.

In particular, in an embodiment of the present invention, at least two light emitting modules of the laser light emitting unit 502 may be provided, so that a plurality of points may be simultaneously measured during a single measurement. That is, as shown in FIG. 8, assuming that the laser light emitting unit 502 includes six light emitting modules, distances can be simultaneously measured for six points 902 on the same line 901 as in FIG. 9. There is.

Furthermore, in the present invention, as the angle of the head 103 is changed, the distance is sequentially measured, so as to measure the distances of not only points on the same line 901 but also points distributed throughout the area.

10 is a diagram illustrating a conceptual diagram of measuring distances of a plurality of points 1001 on an area according to an embodiment of the present invention.

As shown in Fig. 9, after measuring the distance to the points 902 on the same line 901, the angle of the head 103 is changed (for example, after raising or lowering the angle of the head 103) When measuring the distance, it is possible to measure the distance to the points 902 ′ on the other collinear 901 ′.

When such an operation is repeated, distances to the plurality of points 1001 distributed on the region may be sequentially obtained.

That is, in order to provide a guide for putting to the user, green information between a golf ball and a hole must be obtained, and in order to obtain the green information, a distance to a corresponding area is measured.

If the distance is sequentially measured as described above, the measurement situation may change little by little each time the measurement is made due to a user's hand shake or an operation error. Therefore, it is proposed to keep such a measurement situation constant through the gimbal unit 110 described above.

That is, in order to compensate for a case in which the measurement situation such as the head 103 is tilted due to a user's manipulation error, the gimbal unit 110 is proposed to maintain the tilt of the head 103 fixedly.

11 is a view showing a conceptual diagram for calculating a height based on a distance to a point according to an embodiment of the present invention.

As shown in the drawing, the putting auxiliary terminal 100 may measure a first distance d ₁ to the first point 1101 at a first angle θ ₁ . Using the first distance (d ₁ ) and the first angle (θ ₁ ) measured in this way, the height of the corresponding point and the first height difference (h ₁ ) of the putting auxiliary terminal 100 are calculated using Equation 1 below. You can get it.

That is, through the first height difference h ₁ , the height difference g ₁ between the current height h _ref and the first point 1101 can be obtained as in Equation 2.

In addition to this, the height difference between the two points can be obtained regardless of the current height (h _ref ).

12 is a diagram illustrating a method of calculating a height difference between two points according to an embodiment of the present invention.

The first height h ₁ and the second height h ₂ may be calculated in the manner described above in FIG. 11.

When the calculated first and second height differences are subtracted, the height difference Δh between the first point 1101 and the second point 1201 can be obtained as in Equation 3 below.

When the above process is repeatedly performed, height information for a plurality of points 1001 positioned on an area may be obtained as shown in FIG. 10.

Based on these technical features, the present invention proposes to operate in the following order.

13 is a green information acquisition scenario according to an embodiment of the present invention.

14 is a diagram illustrating a measurement scenario at a measurement location according to an embodiment of the present invention.

In step S1301, the user moves to the measurement position. 14, in an embodiment of the present invention, the golf ball 1402, the hole 1403, and the putting auxiliary terminal 100 are located in a straight line 1401, and the golf ball 1402 is approximately The measurement position is about 2m behind. However, the present invention is not necessarily limited to such a measurement location.

For such a straight line 1401 position, the laser pointer unit 122 according to the present invention may provide a guide guide to a user by irradiating a laser indicating a straight line. For example, when the user presses the button 109, such a laser may be irradiated.

The user may input the golf ball 1402 to start the measurement while pointing at the golf ball 1402. Such an input may be, for example, a method of pressing the button 109 firmly.

The pointing state means a state in which the head 103 points to the golf ball 1402 so that measurement can be started based on the golf ball 1402. To this end, a point indicated by the laser pointer unit 122 may be pointed toward the golf ball 1402, or a method of adjusting the direction so that a predetermined indicator 1405 of the display unit 151 matches the golf ball. will be.

When the putting auxiliary terminal 100 starts measuring, as described above, while sequentially measuring distances to several points on the same line, information on a plurality of points on the area may be obtained. At this time, the user may gradually measure the distance while changing the angle, such as gradually raising or lowering the position of the head 103, but the angle of the head 103 is automatically adjusted by the power unit provided in the head 103 itself. As it changes, the scan may be made.

Such a scan may be performed sequentially until it reaches the hole 1403. For example, in the case of a manual scan, the user may slowly lift the position of the head 103 and scan until the point is changed to the hole 1403 while pointing at the golf ball 1402.

In addition, in the case of automatic scanning, the power unit of the head 103 may change the angle of the head 103 and may be performed until it is detected as pointing to the hole 1403.

As an example, if the hole 1403 is pointed after sequentially being scanned by the scan operation, the user may manipulate the button 109 once more to complete the scan operation.

During such a series of scan operations, even if the handle 102 is shaken or rotated due to a user's hand shake or an operational error, the inclination of the head 103 can be effectively fixed by the operation of the gimbal unit 110 described above. In addition, the measurement situation will be kept constant, and green information can be obtained with high accuracy.

Meanwhile, as shown in FIG. 14, an image captured through the camera 121 may be displayed on the display unit 151, but when the camera 121 is not provided, information including a simple indicator may be displayed. An example of information displayed in this way will be described with reference to FIG. 15.

15 is a diagram illustrating display information in a measurement process displayed according to an embodiment of the present invention.

According to the drawing, a hole indicator 1501 for indicating a hole and a ball indicator 1502 for indicating a golf ball are displayed in order to convey an intuitive measurement process to the user. In addition, when the shooting is started while the golf ball is pointing, values 1504 and 1505 for indicating the position value of the golf ball are displayed.

For example, the first numerical value 1504 means the measured distance between the putting auxiliary terminal 100 and the golf ball. For example, a first number 1504, marked 234, indicates that the measured distance is 234 cm.

The second value 1505 may indicate what is the difference in height from the current location. +3 can mean that the golf ball is positioned +3cm higher than my current position.

When scanning is performed sequentially, corresponding values may be sequentially displayed on the display (refer to FIG. 15(b)).

Finally, when the scan is made to the hole, the putting auxiliary terminal 100 may display the position value 1510 of the hole. If you analyze the location value of this hole (1510), you can see that the distance to the hole is 987 cm, and the height of the hole is +10 cm higher than the height of my feet.

16 is a diagram illustrating an example of outputting a putting guide according to an embodiment of the present invention.

As described above, when green information on the putting area is obtained, the controller 180 according to an embodiment of the present invention analyzes the green information and calculates the location to which the putting area should be put. Can provide.

Referring to FIG. 16, a first guide value 1601 is a distance between a user and a hole, a second guide value 1602 is a value representing an additional force (or less force), and a third guide value ( 1603) indicates how far to the left or right of the hole to hit. In particular, the third guide value 1603 may be output to the left when targeting the left side of the hole, and may be output to the right side when targeting the right side of the hole.

In the example of FIG. 16 (a), the distance between the user and the hole is 9.87m, and the position of the hole is slightly high, so the force will be applied to roll more about +8cm, and it means a guide to hit 45cm to the right of the hole .

In the example of FIG. 16(b), since the distance between the user and the hole is 4.22m, and the location of the hole is slightly lower, it means a guide to hit with a target of 30cm to the left of the hole so that it can roll less by -19cm. .

17 is a diagram illustrating putting guide information according to another embodiment of the present invention.

According to the illustrated drawing, as in FIG. 16, first to third guide values 1601 to 1603 are output. This guide value will be as described above in FIG. 16.

Additionally, in the present invention, the predicted putting curve 1701 may be further output and provided.

The predicted putting curve 1701 substantially provides a path for the golf ball to move to the user, and thus, may be a more effective and intuitive putting aid.

The control unit 180 according to an embodiment of the present invention proposes to reflect the temperature and/or humidity in guiding the strength of the force to be struck (that is, in determining the second guide value).

As described above, the sensing unit 140 is provided to measure temperature or humidity, and since temperature and humidity are factors that affect the frictional force between the green and the golf ball, a putting guide reflecting this is provided.

Therefore, the controller 180 controls to lower the second guide value as the measured temperature increases relatively, and may control to increase the second guide value as the measured temperature decreases.

Conversely, when the humidity is high, the frictional force between the golf ball and the green increases, so the controller 180 controls the second guide value to increase as the measured humidity is relatively high, and the second guide value is increased as the humidity is relatively low. You will be able to control it to lower it.
