Description

Golf hitting analysis apparatus, golf training system using the apparatus and method

The present invention relates to a golf hitting analysis device, a golf practice system and method using the same, in particular when hitting the golf ball to determine the direction and strength of the golf ball through a simple device golf hit analysis to enable the virtual golf practice A device, a golf practice system and method using the same.

As golf interest increases, a variety of golf practice devices are emerging, and the swing and putting motions can be sensed to correct golf posture or play a game on the field so that golf can be enjoyed effectively even in a narrow place. Methods are also well known.

The most common method is to track the trajectory of the golf ball through the camera so that you can enjoy golf practice or virtual games. There are environmental constraints to distinguish, and the user with poor eyesight has the inconvenience of difficult to hit correctly.

In particular, since it is difficult to check the exact hitting by the camera alone, there is a problem that the configuration of the exercise book is complicated and the installation cost is high because additional devices such as configuring the sensor at the swing position to check additional information are used.

In order to solve this problem, Korean Patent Publication No. 10-2006-0082350, a virtual golf game system, wherein unit cells capable of detecting an impact of a golf ball size are arranged in a matrix form, and a virtual game provided through a beam projector is displayed. A system that prepares a screen and puts a sensor on the tee hitting the ball to measure the speed of the ball through the time difference between the point of impact and the point of impact, and estimates the trajectory of the golf ball by identifying the location of the hit cell. This has been presented. However, the screens applied to these systems are difficult to manufacture and have a very high manufacturing cost, and due to the low precision of the shock sensor, which requires a thin, flexible material in the form of a screen, the actual impact amount cannot be accurately calculated. After grasping the speed, the tee sensor is required to compensate for the impact measurement.

Therefore, there is a limit that is too expensive and complicated to install, because it is easy to install and move, and accurate impact analysis is possible with a low cost device.

In another method, Korean Patent Publication No. 10-2001-0073639, a simulated golf game system and a game method using a simulated golf game device and a network, also includes a target membrane in which electrodes are intersected so as to determine the location of the hit, and a golf ball hitting time point. After configuring the microphone to confirm the time, the time difference between the time the golf ball hits the target membrane at the time when the sound of the golf ball is hit to predict the speed of the golf ball, the electrodes formed on the target membrane by the ball Use the method of checking the direction of the golf ball by grasping the contact position. Therefore, this method also has a complex limitation in that the target membrane must be installed and a separate impact measuring sensor must be configured at the impact point, and since the impact strength against the actual target membrane is not measured, a short distance speed is relatively large. There is a problem that the distance must be estimated only by measuring.

As such, the conventional method uses a camera and additional sensors, uses a costly and difficult to manufacture sensor matrix screen and a hitting point sensor, or checks a target position and a hitting point for a simple positioning that a flying distance measurement error occurs. Because of the use of sensors, installation is complicated, expensive, or low accuracy. In particular, these screen-mounting methods require some measure of swing, but it is difficult to measure high-precision putts, which requires separate putting measuring equipment, and the practical application of draw, hook, fade, and slice as the ball rotates. It is difficult to grasp the hitting state, so only a simple game is possible, and there is a limit in analyzing the golf habits and providing advice or failing to reflect misses or intentional rotations according to these habits.

Therefore, there is an increasing demand for a device that is simple to install, low in cost, and accurately measures the trajectory and hitting strength of a golf ball, and enjoys a virtual game of golf or coaches on a hitting habit through a simple device. There is an increasing demand for a system that can receive.

Hereinafter, a golf striking analysis apparatus according to an embodiment of the present invention, a golf practice system and method using the same will be described with reference to FIGS. 1 to 8.

1 is a conceptual diagram illustrating a golf practice system using the golf striking analysis apparatus and its operation method according to an embodiment of the present invention, as shown, a plurality of impact amount corresponding to the target point hit the golf ball 300 It is provided with the measurement sensors 180 to analyze the direction and the distance of the golf ball and transmits the analysis result in a predetermined communication method, and the blow analysis device 100 is in communication with the blow analysis device 100 And a user terminal 200 which provides the golf game information reflecting the coaching information or the hit analysis result using the received analysis result.

The illustrated impact amount measuring sensors 180 may be expressed in different patterns or colors, respectively, and may be configured to hit the golf ball 300 toward a desired target through such different expressions.

The impact sensor 180 is composed of a sensor capable of measuring accurate and precise impact amount, strain gauge, piezoelectric sensor, mechanical structure sensor, load cell, acceleration sensor, shock sensor, vibration sensor, inertial sensor using them , Force sensors, torque sensors, gyro sensors, piezo sensors, touch sensors, etc., in addition to one or more of a variety of sensors, such as yaw sensors, speed sensors, rotary sensors, pressure, density, and volume sensors This can be applied.

On the other hand, the impact amount measuring sensor 180 is composed of a sensor unit for measuring the impact of the golf ball and an impact absorbing unit for absorbing the impact of the golf ball, although not specifically shown so that the hit golf ball 300 is not bounced excessively Can be. Alternatively, the shock absorber for absorbing the hit of the golf ball may be configured in the installation portion of the hit analysis device 100 is installed the impact amount measuring sensors 180.

The impact analysis device 100 may be configured of an impact case measuring sensors 180 and an outer case including the internal components described below with reference to FIG. 2, and may be easily disposed and moved to a desired position as a single device. When hitting the golf ball 300 at the hitting distance of a predetermined distance to match the impact amount measuring sensors 180 of the hit analysis device 100, the direction and strike through the sensing value of the at least one impact amount measuring sensor 180 hit The result of the distance analysis according to the intensity can be provided as a hit analysis result.

In particular, as shown, the impact sensor 180 is a structure that can be applied to the sensor capable of precise measurement, and the structure can be in close contact with the ground, as well as the swing analysis of the golf ball 30 as well as putting analysis It is possible.

On the other hand, each of the impact measuring sensors 180 can be given a unique index for the convenience of hitting direction analysis, the center is set to '0', the positive value on the right side, the negative value on the left side index May be set.

As shown, the user may strike the golf ball 300 to target the impact amount measuring sensor of the desired pattern or color among the exposed impact amount measuring sensors 180 of the impact analysis device 100, the impact amount measuring sensor located in the center (C) the index '0' can be determined as the direction information, and when hitting the impact measurement sensor on the right side (D) the index '2' can be determined as the direction information and hitting the impact sensor (B) the index '-2' may be determined as the direction information. If the plurality of impact sensor measuring the right impact at the same time (E) may be determined as the direction information '3.5', the average value for the index '3' and the index '4'.

Of course, the index information may be determined by a desired pattern of numbers, and all of them may be set to a positive number instead of a negative number, or the index may be determined to an even value so that the average value does not represent a decimal point.

In addition, when hitting a plurality of impact measuring sensors at a position biased to one side instead of the center of the impact measuring sensors to obtain more accurate direction information (A), the average of the index may be determined as the direction information, but each impact measuring sensor The index value (for example, -3.7) that reflects the degree of bias may be determined as the direction information by using the deviation of the sensing values. In order to avoid such a decimal point operation, an index value may be calculated by multiplying 10 by 1 decimal resolution or by 100 by 2 decimal resolution.

Alternatively, the index combination of the impact amount measuring sensors in which the impact occurred may be provided as a result of analysis on the direction.

However, in the case of recently used controllers, even a small microcontroller has enough computation speed or internal memory to enable a high level of mathematical operation. Therefore, the index can be used to calculate the direction information at high resolution or to accurately measure the angle information about the direction. You can also compute.

2 is a block diagram of a golf striking analysis device according to an embodiment of the present invention, the impact amount measuring sensors 180 and a plurality of impact amount measuring sensors 180 are installed to correspond to the golf ball hitting point, as shown The connected input and output unit 160 to collect the electrical signal according to the impact amount and convert it into a digital value, and the input and output unit 160 through the measured values of the impact amount measurement sensors 180 converted to a digital value of the golf ball A calculation unit 150 that calculates and provides a blow analysis result including a flying distance and a direction, a communication unit 120 connected to an external user terminal in a preset communication method and providing a blow analysis result calculated by the calculation unit 150; The controller 110 may provide the impact amount information of the impact amount measurement sensors converted through the input / output unit 160 to the calculation unit 150 and provide the impact analysis result of the calculation unit 150 to the communication unit 120.

In addition, as shown in the drawing, the control unit 110 is selectively connected to the control unit 110 and displays a result of the hit analysis, or generates a signal according to a user input and provides the signal to the control unit 110 so that the control unit 110 communicates with the communication unit 120. ) May further include an interface unit 140 for setting communication of the communication unit, starting an analysis operation, changing the operation parameter in the operation unit 150, or changing the display content and method of the display unit 130. .

For example, the communication unit 120 supports serial or parallel wired communication methods (RS232, RS485, USB, optical communication, etc.) or various types of wireless communication methods (Bluetooth, RF, Wi-Fi, infrared, UWB, RFID, WiBro, LoRA, etc.). It can support at least one of.

For example, the display unit 130 may be a simple lighting means (LED, etc.), a means for displaying text (FND, text LCD, etc.), or a means for displaying a variety of information (graphic LCD, etc.).

The input / output unit 160 preferably includes an analog-to-digital conversion configuration for receiving analog signals from the impact amount measuring sensors and converting them to digital values.

The interface unit 140 may include input means such as a switch, a button, a joystick, a dial, a jog shuttle, and the like for receiving a user input.

The control unit 110, the operation unit 150, the input / output unit 160, the communication unit 120, and the like may be integrated as a single microcontroller, or may be separately configured by separate hardware means for performing each function.

Herein, the controller 110 assigns an identifier of a numerical format to the impact amount measuring sensors 180 connected to the input / output unit 160, and the operation unit 150 strikes based on the identifiers of the impact amount sensors 180 having an impact. The information about the direction is calculated, but when an impact occurs in the plurality of impact amount sensors 180, an arithmetic value of the identifier combination or identifier of the impact amount sensors 180 having the impact may be provided as a result value for the direction. .

The calculation unit 150 may calculate the estimated distance by checking the strength of the blow using the measured values of the impact amount measuring sensors 180 converted into digital values, and provide the result as an analysis result. Of course, the measured values may be included in the impact analysis result so that the user terminal with better performance may be calculated by reflecting additional parameters.

Although not shown, the apparatus may further include a power supply unit such as a battery unit or an external commercial power connection unit for providing power.

3 is a conceptual diagram illustrating an example and an operation method of the golf striking analysis apparatus according to another embodiment of the present invention. As shown in FIG. Direction measurements can be extended in two dimensions. In this case, up to four impact amount measuring sensors 185 may be simultaneously hit, and an index may be assigned to each impact amount measuring sensor 185 and combined or arithmetically calculated, or may be determined based on the impact amount of each impact amount measuring sensor 185. It is also possible to calculate the angle for.

In addition, in order to visually distinguish the target from the user, each impact sensor may be expressed in a different pattern or color, or may be represented by a target shape having a circular concentric shape with respect to the center.

In the illustrated example, the user may strike the golf ball 300 to target the impact amount measuring sensor of the desired pattern or color among the exposed impact amount measuring sensors 185 of the hit analysis device 100, the impact amount is located in the center In case of hitting only one sensor (Sensor 32) (c) The index, x-axis and y-axis angle information of the sensor can be calculated and determined as direction information, and two impact sensor (No. 12, 21) can be determined simultaneously. (A), the direction information is determined through a combination of indexes 12 and 21 (e.g., 1221) or an index representing a direction through a predetermined calculation operation, or the x-axis according to their average position (boundary), The y-axis angle information may be calculated and determined as the direction information. If, at the same time hitting four of the impact measuring sensors (33, 34, 42, 43) (d), the combination of the index 33, 34, 42, 43 (for example 33344243) or a predetermined arithmetic operation The direction information may be determined through an index representing a direction, or the x and y axis angle information according to their average positions (four contact parts) may be calculated and determined as the direction information. Alternatively, when four sensors 29, 30, 38, and 39 of the impact measuring sensors are biased and hit at the same time (b), a combination of indexes 29, 30, 38, and 39 (for example, 29303839) or a predetermined The direction information is determined through an index representing the direction through arithmetic operation, or the angle information is calculated by calculating the x-axis and y-axis angle information according to their average positions (four contact points), or each impact amount measurement sensor According to the impact amount pattern, the partial x-axis and y-axis angle information that is biased toward the sensor 30 may be calculated and determined as the direction information.

Such a direction information calculation method may be determined according to a calculation method of an operation unit calculating direction information or a communication format with a user terminal receiving a hit analysis result through a communication unit, and calculates an angle according to an index or an index combination / operation method. A matching formula for calculating an angle by referring to a look-up table in which a formula or x-axis and y-axis angle information is stored in advance may be configured in an operation unit or a user terminal.

Figure 4 is an exemplary view showing a golf game process of the user terminal according to an embodiment of the present invention, the hit analysis device analyzes the hit of the golf ball hitting the analysis result including the distance information according to the direction information and the impact amount It may be provided to the user terminal through the communication unit, the user terminal may provide a golf game screen as shown by using the result of the hit analysis. As shown in the figure, when the user hits the actual golf ball and hits the hit analysis device, the screen may be provided to proceed with the virtual golf game by reflecting the result of the hit analysis according to the direction and distance.

In this case, the user terminal may apply a predetermined weight to the hit analysis result in consideration of the state of the golf course (field height, field state, wind direction, etc.) to reflect the game in the game in order to increase the realism.

Of course, it is possible to present a goal other than the golf game and to check whether the user has hit the correct goal, display the result, or provide information for coaching the user's hit through the hit analysis result.

However, in the above-described method, since only the information about the hitting position and strength of the golf ball is used, the golf ball is substantially rotated, so that the ball cannot be sent in the desired direction, or conversely, the golf ball is hit by rotating the golf ball for effective green attack. In this case, it is difficult to measure the rotation even through a camera or a sensor disposed in the hitting area.

In another embodiment of the present invention, it is possible to measure the direction and the degree of rotation of the golf ball through the impact analysis device composed of precise impact amount measuring sensors only to increase the realism or to enable practical habit coaching for the user.

FIG. 5 is an exemplary configuration diagram of a golf striking analysis device further adding an impact dispersion unit according to an exemplary embodiment of the present invention, and illustrates a method of applying the impact dispersion unit 190 configured to be the simplest.

5A is coupled to the impact dispersion unit 190 for interconnecting each impact amount measuring sensor to the front of the impact amount measuring sensors 180 (for example, some areas of the front surface of the impact amount measuring sensors 180 is the impact spreading unit) And a method of adhering to (190)), the impact analysis device 100 as illustrated in FIG. 5B may be configured.

Of course, although not shown, the impact dispersion unit 190 may be formed to expose such an expression by reflecting an expression method such as a pattern or a color of each of the impact amount measurement sensors to be connected, and for the convenience of production, the expression may be expressed in the impact amount measurement sensors The expression method for distinguishing the target may be applied to the impact dispersion unit 190 on the front side without applying the method.

In addition, the impact dispersion unit 190 may be configured to be sensitive to the rotation of the golf ball hitting so that the relatively high friction material (rubber material, silicon material, etc.) is configured on the front surface at least exposed.

The impact dispersion unit 190 may be configured in such a manner as to interconnect them in at least one portion of the side, the rear, not the front of the impact amount measuring sensors as shown.

FIG. 6 is a conceptual view illustrating a golf ball rotation detection method of a golf striking analysis device to which an impact dispersion unit according to an exemplary embodiment of the present invention is applied. When the right rotation is applied to the golf ball 300 as shown in FIG. When hitting the part 190, the force according to the rotation is applied to the impact dispersion unit 190, as shown by the dashed arrow pulls the impact dispersion region on the right side as the ball rotates, on the contrary, the impact dispersion unit on the left side Will push the area.

If the golf ball hits the right amount while hitting the impact amount sensor In5, which is the center of the nine impact amount sensors In1 to In9, the impact amount of the impact amount sensor In5 is the largest as shown in FIG. Accordingly, the impact amount measuring sensors (In6, In7, In8, In9) disposed on the right side of the hitting point are also sequentially generated in accordance with the force pulled by the impact dispersion unit 190, and the impact amount measured on the left side of the hitting point Some of the sensors In4 and In3 may output values in a direction in which the impact dispersion unit 190 is opposite to a value generated in the impact direction as the impact dispersion unit 190 is pushed up.

Of course, although the measurement pattern of the form different from FIG. 6B may appear depending on the type and the measuring method of the impact amount measuring sensor 180, the impact dispersion unit 190 to distribute the force in a unique pattern around the impact point as the rotation By analyzing the measured values of the impact amount measuring sensors in which the impact is dispersed in a specific pattern it can generate information to distinguish the direction of rotation and strength of the golf ball hit.

7 is an exemplary view of the output pattern of the impact measurement sensors according to the golf ball rotation according to an embodiment of the present invention, the draw or hook, the golf ball is rotated to the left according to the typical golf ball rotation shown in Figure 7b If the measurement pattern of the impact measuring sensors according to the straight without rotation of the fading, slices, or rotation of the ball is defined as shown in FIG. 7A, the rotation direction and the intensity of the rotation may be analyzed according to the pattern matching of the impact measuring sensors measured during actual hitting. It becomes possible.

This may be performed in the calculation unit of the hit analysis device and included in the hit analysis result. The raw data of the measured impact amount sensors may be transmitted to the user terminal, and the rotation direction and the intensity of the rotation may be analyzed by the user terminal. .

8 is an exemplary view showing in three dimensions the impact amount measurement results of the impact amount measuring sensors measured when the golf ball rotated to the right hits the sensor 32 when using the impact amount sensor matrix shown in FIG.

As shown, the impact amount of the hitting point is the largest, and a large amount of impact is measured on the impact amount measuring sensors located on the right and the upper and lower parts of the hitting point by the impact dispersion of the impact spreader according to the right rotation. As the impact dispersal is pushed or lifted, the measured impact amount may be reversed.

The three-dimensional pattern may also have a different shape according to the type and the measuring method of the impact amount measuring sensor, but a specific pattern (including the rotation of the upper and lower sides as well as the described left and right) may be formed according to the rotation of the ball. By distinguishing, the direction and strength of the ball's rotation can be analyzed.

The user terminal receives or calculates rotation information such as the rotation direction and strength of the ball, thereby providing the user with an analysis result about the direction, strength (flying distance), and rotation type of the ball, and providing appropriate coaching information and miss information. By providing a golf game that reflects the result of such a hit analysis, it is possible to provide a game result reflecting the influence of the rotation when the user intentionally rotates, thereby providing a simple and inexpensive device using only a single sensor. While using it, it is possible to accurately analyze and practice various hits (swing and putting) and to play a realistic game.

In the above described and illustrated with respect to preferred embodiments according to the present invention. However, the present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art without departing from the gist of the present invention attached to the claims. .
