Description

A method for evaluating the impact of a golf ball and a virtual golf device using the same

The present invention relates to a method for evaluating a hit of a golf ball, and more particularly, when a golf ball moves from a previous position to a current position due to a user's hit, the current position based on play information data at the previous position and the current position. The present invention relates to a method for evaluating the impact of a golf ball, which can objectively evaluate the impact of moving the golf ball, and a virtual golf device using the same.

Golf is a sport in which a golf ball is hit and put into a hole cup, and a game is decided by comparing the number of hits from an initial hit until the golf ball enters the hole cup. Golf usually plays 18 holes in a round, and the total number of hits is expressed by adding the number of times the golf ball is hit for each hole, or the number of hits based on the number of fewer/more hits based on the set number of strokes for each hole express the number of times For example, if you say 'I hit 5 under par in today's round', it means that I hit 67, which is 5 fewer strokes than the 18-hole 72.

As described above, since the game is decided by comparing the number of blows per round, golf usually pays attention only to the final result of the total number of blows. For example, if a golfer hits a total of 70 in an 18-hole play, I think that 70 is only a good record equivalent to 2 under par based on the legal number of strokes of 72 in 18 holes. However, among the 70 strokes, there may be good shots and bad shots, so if each hit can be evaluated in an appropriate way, the golfer can improve his skills by maintaining the good shot and supplementing the bad shot appropriately. Therefore, it is necessary to properly evaluate not only the final number of strokes, but also how good or bad each shot is in order to improve the golfer's skill. Since there is no such thing, related technology development is required.

The present invention was invented in view of the above circumstances, and an object of the present invention is to provide a method for evaluating the impact of a golf ball configured to objectively evaluate the impact of a golf ball.

Another object of the present invention is to provide a virtual golf device using the method for evaluating the impact of the golf ball.

In addition, other objects of the present invention can be clearly understood from the following description and accompanying drawings.

A method of evaluating impact of a golf ball according to an embodiment of the present invention is a method of evaluating impact of a golf ball when a user's impact moves the golf ball from a first position to a second position. A first step of collecting play information data for the game, a second step of calculating batting grades at the first and second positions based on the collected data, and a batting grade at the first position and a batting grade at the second position and a third step of evaluating a hit that moves the golf ball from the first position to the second position based on the grade.

In the method of evaluating the impact of the golf ball, calculating the impact rating at a specific position in the second step includes the selection step of selecting a position range related to the specific position and the position among the plurality of users. A calculation step of calculating a blow grade using a final blow result of a user who has hit within the range may be included.

In the method of evaluating impact of the golf ball, in the selecting step, the location range may be selected as a location within a predetermined range from the specific location. Alternatively, in the selecting step, the location range may vary according to at least one of the distance from the specific location to the hole cup, the type of hitting at the specific location, and the type of terrain at the specific location.

In the method for evaluating the hitting of the golf ball, in the calculating step, final hitting results of a plurality of users are divided into a plurality of cases according to the number of strokes, and each of the plurality of cases is sequentially classified in order of high or low number of strokes. Points may be assigned, and a point corresponding to a case occupying the highest ratio among the plurality of cases may be calculated as the hit rating. Alternatively, in the calculating step, the final batting results of a plurality of users are divided into a plurality of cases according to the number of strokes, a specific case is selected from among the plurality of cases, and a ratio of the specific case to all cases is calculated, and then the ratio According to this, the hitting rating can be calculated. Here, the plurality of cases include a case in which the final hitting result is a Hole-In-One, a case in which the Albatross is a case, a case in which an Eagle is a case, a case in which a birdie is a case, and a par At least two of the following: In Case, Bogey Case, Double Bogey Case, Triple Bogey Case, Quadruple Bogey Case, Double Par Case may contain more than

In the method for evaluating a hit of the golf ball, the hit of the golf ball may be a hit on a real golf course or a hit on a screen golf course.

A virtual golf device according to an embodiment of the present invention includes a display unit showing a virtual golf course and a virtual golf ball, and when a user hits a golf ball, the virtual golf ball corresponding to the hit golf ball on the virtual golf course. It includes a calculation unit that calculates the trajectory of the golf ball and an evaluation unit that evaluates the impact of the golf ball by the user according to the aforementioned method of evaluating the impact of the golf ball.

FIG. 1 is a flowchart illustrating the operation of a method for evaluating impact of a golf ball according to an embodiment of the present invention, and FIGS. 2 to 5 are diagrams for exemplarily explaining the second step of FIG. 1 .

Referring to FIG. 1 , a method for evaluating a hit of a golf ball according to an embodiment of the present invention includes a first step (S10) of collecting play information data for a plurality of users and calculating a hit rating based on the collected data. A second step (S20) and a third step (S30) of evaluating the impact of moving the golf ball to a predetermined position.

Referring to FIG. 2, in a play on a specific golf course of a golf course, a user hits a golf ball at a first position P1 away from a hole cup by a first distance D1, so that the golf ball moves at a second distance D2 from the hole cup. ), and a method of evaluating a blow moved from the first position P1 to the second position P2 will be described by taking this case as an example.

In the first step (S10), play information data for a plurality of users including not only the user who performed the blow but also other users is collected. Here, the hitting may be a hitting at a screen golf course mainly equipped with a virtual golf device. In screen golf courses, a log-in system is generally applied and a database in which play records of logged-in users are stored is provided. Accordingly, the user's play information data can be easily collected by extracting relevant information from the database. Meanwhile, the hit may be a hit in an actual outdoor golf course. In recent years, high-tech mobile devices such as smart phones and tablets have become widely available, so it is possible to input a play record for every hit even in an actual golf course while carrying the mobile device. The input record may be stored in a database of a server operated by a golf course service provider, and in this case, user play information data may be collected by extracting related information from the database of the server.

In the second step (S20), based on the data collected in the first step (S10), hitting ratings are calculated at each of the first and second positions (P1, P2). The hitting ratings at the first and second positions P1 and P2 may be calculated in the same manner, and are composed of a selection step S21 and a calculation step S22 in detail. In the selection step (S21), among the data collected in the first step (S10), data to be used for calculating the batting grade is selected, and in the calculating step (S22), the batting grade is calculated using the selected data.

There may be various selection criteria in the selection step (S21), and some of them will be described as examples with reference to the drawings. In FIGS. 3 and 4 , it is assumed that the target position for which the hitting grade is to be calculated is denoted by reference numeral 'P' and the target position P is separated by a distance of 'D' from the hole cup. The method of calculating the blow grade for the target position P may be equally applied to the calculation of the blow grade at the first and second positions P1 and P2.

Referring to FIG. 3 (a), a predetermined range (1) is selected from the area at the same distance (D) as the hole cup and the target position (P), and the selected range (1) is used for calculating the hitting rating. data can be extracted. Here, the data is data of hitting results when the current user and other users hit in the selected range (1). Since only the data of the currently playing user extracted from the target position (P) is not sufficient to calculate the hitting rating, the range is extended to positions correlated with the target position (P), and positions within the range Extract the hitting result data when the user and other users hit in the . Locations at the same distance as the target location P can be considered to have a certain degree of correlation with the target location P, and by using these data, a sufficient amount of data required to calculate the blow grade can be secured.

The range 1 may be in the form of a circle having the distance D as a radius or may be in the form of an arc including a part of the target position P in the circle. Whether the range 1 will be in the form of a circle or an arc, and in the case of an arc, how long it will be can be determined in various ways. As one method of setting the range (1), the target amount of the number of data to be used for calculating the blow rating is set, and the length of the arc is expanded symmetrically from the target position (P) until the target amount is reached can think of a way. For example, when the length of the arc is expanded to a predetermined length symmetrically centered on the target position P, and at this time the number of data reaches the target amount, the range to be used for calculating the blow grade within the range of the predetermined length (1 ) is confirmed. If the number of data is insufficient to the target amount even if the length of the arc is extended to the predetermined length symmetrically with the target position P as the center, the range is extended to a length longer than the predetermined length to check whether the target amount is reached. . In this way, it is possible to determine the range of data to be used for calculating the hitting rating, and if the number of data is insufficient to the target amount even if the length of the arc is continuously expanded, the range (1) may be in the form of a maximum circle. Meanwhile, in addition to the method of determining the range 1 by setting a target amount in this way, a method of simply randomly determining the range 1 may be applied.

Referring to FIG. 3 (b), a region range (1) located at the same distance (D) as the hole cup and the target position (P) is specified, and data to be used for calculating the hitting grade is selected for the range (1) can The range 1 may be in the form of a circle having the distance D as a radius or may be in the form of an arc including a part of the target position P in the circle. The method described with reference to FIG. 3(a) can be applied to whether the range 1 will be in the form of a circle or an arc, and in the case of an arc, how long the arc will be. In addition to this, other variables may be additionally considered. For example, the type of terrain at the point where the golf ball is placed may be considered. As shown in FIG. 3 (b), assuming that the target location P where the golf ball is currently placed is the fairway terrain and there is a bunker terrain near the target location P, the range of data to be used for calculating the hitting rating is determined In this case, only the arc-shaped range (1) excluding the area (2) belonging to the bunker topography may be selected as data to be used for calculating the strike rating. In a bunker, you have to hit a golf ball while bouncing sand, and this has a difference in the feeling of hitting and the difficulty of hitting compared to hitting on a fairway, which is a grass area. Therefore, in calculating the hitting grade at the target position (P), using even the hitting result data in the bunker area that has different attributes from the target position (P) calculates the hitting grade at the target position (P) belonging to the fairway area It can be considered inappropriate to do it, and it is desirable to exclude it.

For reference, the topography of a golf course may include fairways, roughs, bunkers, greens, and the like. In general, the fairway is a normal grass area and occupies a considerable area in the golf course, the rough is composed of longer grass than the fairway, so it is difficult to hit the golf ball compared to the fairway, the bunker is an area made of sand, and the green is This is the grass area where the hole cup, the final goal of golf, is placed.

Data to be used for calculating the blow rating may be selected in a manner different from that shown in FIG. 3 .

Referring to FIG. 4 (a), a range (1) of an area in a predetermined radius (R) centered on a target position (P) separated by a predetermined distance (D) from the hole cup is specified, and the range (1) Data to be used for calculating the blow rating can be selected for the target. Here, the data is data of hitting results when the current user and other users hit in the selected range (1). Since the amount of data extracted from the target location P alone is not sufficient to calculate the hit rating, the range is extended to locations correlated with the target location P, and the user and other users at locations within the range Extract the hitting result data when hit. When R is small, positions at the same or similar distance from the target position P can be selected, and these positions can be considered to have some degree of correlation with the target position P, and using these data, the hit It is possible to sufficiently secure the amount of data required to calculate the grade.

The length of the radius R in the range 1 can be determined in various ways. As one method of setting the range (1), consider a method of setting a target amount of the number of data to be used for calculating the hit rating and expanding the length of the radius (R) from the target position (P) until the target amount is reached can see. For example, when the number of data reaches the target amount when the radius R of a predetermined length is reached around the target position P, the range 1 to be used for calculating the blow rating is determined in the range of the predetermined length do. If the number of data is insufficient for the target amount with a radius of the predetermined length centered on the target position P, it is checked whether the target amount is reached by extending the range of the radius to a length longer than the predetermined length. In this way, the range of data to be used for calculating the blow rating can be determined. Meanwhile, in addition to the method of determining the range 1 by determining the target amount, a method of determining the range 1 by simply calculating the radius R at random may be applied. However, if the radius R is too large, hitting result data at a location too far away from the target location P may be used. To prevent this, the radius R is preferably determined within a predetermined limit.

Referring to FIG. 4 (b), a range (1) in a predetermined radius (R) range is specified with the target position (P) separated by a predetermined distance (D) from the hole cup as the center, and the range (1) Data to be used for calculating the impact rating may be selected as a target. The range 1 is in the form of a circle, and the method described with reference to FIG. 4(a) may be applied to how much radius the circle has. In addition, some of the area of the circle may be excluded by additionally considering other variables such as impact or type of terrain. That is, as shown in FIG. 4(b), assuming that the target position P where the golf ball is currently placed is outside the green area and there is a green area near the target position P, the range of data to be used for calculating the hitting rating In determining , only the range 1 of the inner area of the circle excluding the area 2 belonging to the green area may be selected as data to be used for calculating the batting grade. In the green area, 'putting' is performed to roll the golf ball into the hole cup, and outside the green area, 'approach shot' is performed to put the golf ball on the green area. In calculating, it is not desirable to use data from a position where a different kind of putting is to be made.

For reference, hitting types in golf may include a tee shot, an approach shot, and a putt. In general, a tee shot means the first hit on the golf course, an approach shot means a hit after the second shot when the straight line distance from the hole cup is 30m or more, and a putt means a hit when the golf ball is located in the green area. It may mean a hit that rolls a golf ball. Also, in golf, since the type of hitting may vary depending on the type of golf club (wood, iron, putter, etc.) used, the data selection range may vary depending on the type of golf club used.

If the data to be used for calculating the blow grade is selected as described above, the blow grade is calculated using this in the calculation step (S22). It is assumed that the result of analyzing the data selected in the selection step (S21) is the same as the table shown in FIG. That is, in the selection step (S21), a predetermined range including the current position (P) is selected, and data of what results are obtained when the user and other users who are currently playing at the position of the selected range are hit So, it is classified as shown in the table shown in FIG. 5, and the hitting grade at the current position (P) is evaluated using this table. Here, the batting results are divided into 5 categories: 'Eagle, Birdie, Par, Bogey, and Double Bogey', which is an example and is more subdivided than this. It can be differentiated by dividing it or simplifying it more than this. For example, there can be albatross and hole-in-one as better batting results than eagle, and triple bogey, quadruple bogey, and duffel par as worse batting results than double bogey. , Albatross, eagle, birdie, par, bogey, double bogey, triple bogey, quadruple bogey, double par". Alternatively, the items can be simplified and classified into only “birdie, par, bogey, double bogey”. In the case of simplifying the items, the batting results of 'hole-in-one, albatross, eagle' are grouped in the 'birdie' category and all are considered 'birdies', and the batting results of 'triple bogey, quadruple bogey, duffel par' All of them can be treated as 'double view' by tying them to the 'double view' item.

There may be several methods for calculating the blow rating using the above table, and two of them will be described as examples.

<Method 1>

The first method gives points of 'Eagle = 1, Birdie = 2, Par = 3, Bogey = 4, Double Bogey = 5' for each of the five categories of 'Eagle, Birdie, Par, Bogey, Double Bogey' In the case of FIG. 5 (a), since the hitting result was 'bogey' the most, the hitting grade at the corresponding position is calculated as '4' corresponding to 'bogey'. If the same method is applied, in the case of FIG. 5 (b), since the hitting result is 'par' most often, the total hitting rating at the corresponding position is calculated as '3' corresponding to 'par'.

Here, the higher the number of the hitting grade, the higher the difficulty of hitting at the corresponding position. For example, if the batting grade is calculated as '1' at a certain position, this means that 'Eagle' came out the most when the batting results of several users at that position were analyzed, and that the number of eagles came out a lot means that there were holes in that position. Since it means that it is easy to do, the hitting difficulty can be interpreted as low, so the hitting grade is calculated low. Conversely, if the batting grade is calculated as '5' at a certain position, this means that 'double bogey' came out the most when analyzing the batting results of several users at that position, and the number of double bogies came out to the same extent as the number of users at that position. Since it means that it was difficult to hole in, it can be interpreted that the difficulty of hitting is high, so the hitting grade is calculated high.

<Second method>

The second method of calculating the batting rating is to select one of the five classification items of 'eagle, birdie, par, bogey, double view' as a standard item and calculate the percentage of the selected item in the total Based on this, the hit rating is calculated. For example, among 'eagle, birdie, par, bogey, double view', 'birdie' is selected as the criterion item, and the percentage range in which the criterion item 'buddy' appears is classified into several sections and points are given to each section. do. In other words, if the probability of hitting a 'birdie' is 40% or more, '1' point is given, if it is 30-40%, '2' point is given, and if it is 20-30%, '3' point is awarded. In case of 10-20%, '4' points are awarded, and in case of less than 10%, '5' points are awarded. In the case of FIG. 5 (a), the percentage of 'birdies' among the total hitting results is 5% (5/(1 + 5 + 20 + 50 + 24)), and in the case of FIG. 5 (b), the total hitting results Among them, the percentage of 'buddy' is 25% (20/(5+25+40+20+10)). Therefore, in the case of FIG. 5 (a), the hitting result enters the section where the probability of being a birdie is less than 10%, and '5', the point in this section, is calculated as the hitting grade at the corresponding position. In addition, in the case of FIG. 5(b), the probability of a hit result being a birdie falls within the 20-30% range, and '3', a point in this range, is calculated as the hitting grade at that position.

Here, the higher the number of the hitting grade, the higher the difficulty of hitting at the corresponding position. For example, if the batting grade is calculated as '1' at a certain position, this means that it is as easy as 'Buddy' to come out when analyzing the batting results of several users at that position, and there is a high possibility of a good result like 'Buddy'. A high score means that it is easy to hole-in from that position, so it can be interpreted as a low hitting difficulty, so the hitting grade is calculated low. Conversely, if the batting grade is calculated as '5' at a certain location, this means that it is difficult to find a 'buddy' when analyzing the batting results of several users at that position, and the possibility of a good result like 'buddy' is low. Since it means that it is difficult to hole-in from that position, it can be interpreted that the difficulty of hitting is high, so the hitting grade is calculated high.

The first and second methods for calculating the hitting rating from the hitting result are examples, and other methods not described herein may be applied. In addition, one method may be applied alone or several methods may be applied in combination.

As described above, when the hitting rating at a specific location is calculated, the third step (S30) of finally evaluating the hitting of the golf ball is executed. In the evaluation step, the impact of the golf ball is evaluated based on the previously calculated impact rating. When a blow is made from the first position (P1) to the second position (P2), the simplest evaluation method is the value corresponding to the hit rating at the first position (P1) and the hit rating at the second position (P1). It is to calculate the value corresponding to . For example, assuming that the hitting result at the first position P1 is the same as in FIG. 5 (a) and the hitting result at the second position P2 is the same as in FIG. 5 (b), the above-described hitting rating is calculated. According to the first method, the hitting grade at the first position (P1) is 4 and the hitting grade at the second position (P2) is 3. In this case, the first position (P1) to the second position (P2) ), the evaluation value for the blow becomes '1 (= 4-3)'. In addition, according to the second method for calculating the above-described blow grade, the blow grade at the first position (P1) is 5 and the hit grade at the second position (P2) is 3. In this case, the first position (P1 ) to the second position P2, the evaluation value is '2 (= 5-3)'.

Regardless of how the hitting rating is calculated, as described above, a low hitting rating means a low hitting difficulty at the corresponding location, and a high hitting rating means a high hitting difficulty at the corresponding location. Therefore, the higher the value of the "hit evaluation value (= hitting rating at the first position P1 - hitting rating at the second position P2)", the higher the hitting difficulty at the position where the hitting difficulty is high by hitting the golf ball. This means that the golf ball has moved to a lower position. In other words, even though the hitting position is difficult to hit due to the high hitting difficulty, the fact that the golf ball moved to the position where the next hitting was easy and the hitting difficulty was low by hitting from that position indicates that the hit was a good shot. The higher the value, the better the hit. When the hitting result items are divided into 5 items as shown in the table of FIG. 5, the position with the highest hitting difficulty (the position with the hitting rating '5') to the position with the lowest hitting difficulty (the position with the hitting rating '1') When the golf ball is moved, the hit evaluation value becomes the maximum value '4'. However, when a golf ball hit at a specific position becomes a hole-in, if the hitting grade at the specific position is 'A', the targeting of the golf course is completed at the hole-in position and the hitting grade cannot be calculated any more. is set to '0' and the hit evaluation value in case of hole-in at a specific position is selected as 'A (=A-0)'.

Conversely, when the numerical value of the "hit evaluation value" is small, it means that the golf ball has moved from a position where the hitting difficulty is low to a position where the hitting difficulty is high due to the hit of the golf ball. In other words, even though the hitting position is easy to hit due to low hitting difficulty, the fact that the golf ball moves to a position where the next hitting is difficult to hit, even though the hitting position is easy to hit, indicates that the hit is a bad shot. The smaller the value, the worse the hit. When the hitting result items are divided into 5 items as shown in the table of FIG. 5, the position with the lowest hitting difficulty (the position with the hitting rating '1') to the position with the highest hitting difficulty (the position with the hitting rating '5') When the golf ball is moved, the hit evaluation value becomes the minimum value '-4'.

The value obtained by evaluating the impact of the golf ball may vary depending on which of the first and second methods is used to calculate the impact rating in the calculation step (S22). However, if one of the methods is selected and consistently applied whenever the golf ball is hit, the hits of each golf ball can be fairly compared with each other because the hit evaluation is made on the same standard. For example, hitting started at the initial position (position 1), passed through positions 2 and 3, and was holed in, and three hits (position 1 → position 2; position 2 → position 3; position 3 → hole cup) until hole-in The hit evaluation value of 『4 (1 position → 2 position); -3 (position 2→position 3); 1 (3 position → hole cup)”. From the hitting evaluation result, it can be seen that the first shot (position 1→position 2) is a good shot compared to the other shots, and the second shot (position 2→position 3) is a bad shot compared to the other shots. The hit evaluation value may vary depending on whether the first method, the second method, or a different calculation method is applied in the calculation step (S22), but the hit evaluation value for each hit is compared. If you look at it, you can clearly grasp the relative evaluation of each shot.

If the hitting of the golf ball can be evaluated in this way, the hitting of each golf ball can be objectively evaluated, and accordingly, the user recognizes his or her hitting ability to keep good shots and moderately compensate for bad shots to improve golf skills. can do. Evaluating the hitting of a golf ball can be applied to actual golf outdoors, but it can be more effectively applied to screen golf where various high-tech devices are used and play records are easily stored. Hereinafter, several examples in which the above-described hitting evaluation method is applied to screen golf will be described.

6 is a schematic configuration diagram of a virtual golf device according to an embodiment of the present invention, and FIG. 7 is a diagram showing an example of a screen displayed on a screen in the virtual golf device of FIG. 6 .

Referring to FIG. 6 , the virtual golf device according to an embodiment of the present invention includes a hitting plate 10, a control unit 20, a sensing unit 30, an input unit 40, a sound unit 50, and a display unit 60. include

The hitting plate 10 is an area where a user is positioned to hit a golf ball, and a hitting mat is provided in the hitting plate 10 so that the user puts the golf ball on the hitting mat and hits the hitting plate. Although not shown in the drawings, an auto tee having a structure that can move up and down is installed under the hitting mat, so that a golf ball for hitting can be automatically provided to the user through the auto tee.

The controller 20 controls the overall operation of each component of the virtual golf device. For example, the control unit 20 controls the auto tee installed on the hitting mat so that the golf ball for hitting is provided from the auto tee according to the timing of the user's hitting. In addition, when the user selects a specific golf course, the controller 20 performs necessary processing so that the user can play on the golf course. That is, the control unit 20 includes an image processing means for processing an image, so that when a user selects a specific golf course, the image processing means transfers the corresponding golf course image to the display unit 60 so that it can be displayed. . In addition, when a user inputs personal information such as an ID or password for log-in, the control unit 20 may play a role of determining whether to approve the log-in by checking the input personal information.

The control unit 20 includes a calculation unit 21, an evaluation unit 22, and a storage unit 23, and through these, other functions than the control function described above can be performed. The calculation unit 21 calculates a flight trajectory when it is assumed that the golf ball flies in an actual golf course in the sensed state based on the physical state of the golf ball hit by the user. The evaluation unit 22 serves to evaluate the impact of the golf ball when the user hits the golf ball. In evaluating the impact of the golf ball, the evaluation method described with reference to FIGS. 1 to 5 or other evaluation methods may be applied. The storage unit 23 stores various data necessary for the operation of the control unit 20 . For example, user personal information necessary for the user's log-in process, image information for generating a golf course or golf ball image, and user's play record information used when evaluating hitting a golf ball may be stored. there is.
