Description

Method for calculating distance from golf code point to hole cup and related product

Technical Field

The invention relates to the field of golf, in particular to a method for calculating the distance from a golf code point to a cup and a related product.

Background

In a golf game, in order to provide a distance reference to players, a golf game committee generally sprays a number of code points on a field according to the levelness of the players, and measures the distance from the code points to a T point on the front edge of a green. The code points and the related conditions of the lane of the whole court are made into a book code book for a player to determine the distance and know the court conditions. In non-games, the court also usually sets several codepoints in the track, marking the distance to the point before the green. The goal of setting code points on the lane and providing code number books is to enable players to calculate the distance from the code points to the hole cup according to the information provided by the code points. In an event, the player must manually perform the distance estimation.

Code number this method has been used since 1939 british studies for over 80 years. This method has played an important historical role in the history of golf events. Although the code number method has a certain problem, the problem of the code number method is troubling players and events, but no solution is found so far.

To know the nature of the distance between the track code point and the hole cup, the distance calculation method of the code number brings troubles to players and events, and the code number calculation method needs to be scientifically analyzed.

The code number method calculates the distance from the code point of the fairway to the green hole cup, and calculates according to the distance from the code point provided in the code number book to the front point T of the green and the green hole bitmap.

The method for estimating the distance from a code point to a hole cup by using a code number book and a hole location graph is shown in FIG. 1, wherein A is a green hole cup, D is a fairway code point, T is a point before a green, and X is a line before the green. The position of the green hole cup on the green is given by a hole map. The hole bitmap only gives the distance from the hole cup to the front line of the green and the distance from the hole cup to the near-end horizontal edge of the green. Since the distance from the hole cup to the near edge of the horizontal green is not related to the calculation of the distance from the fairway code point to the hole cup, it is not shown in the figure. In FIG. 1, the distance from the cup A to the front line of the green is a. The code number book gives the distance from the fairway code point D to the green front point T. In fig. 1, the distance from the fairway code point D to the front green point T is b. The distance from the track code point D to the hole cup A is D. The method for estimating d by using the code number method is shown as the following formula: namely: d ≈ a + b.

This method has the following problems.

One of the problems is as follows: the distance from the code point of the fairway to the point on the parallel line of the point line of the front edge of all the greens is the same. In FIG. 2, the cups A1, A2, A3 and A4 are on the same horizontal line from the front edge line of the green. D2 is a codepoint in the fairway. In fig. 2, according to the distance estimation formula of the method based on the code number, the distances from the fairway code point D2 to the green cavity cups a1, a2, A3 and a4 are all a + b, which is obviously incorrect. Indeed, it must be D2a4> D2A3> D2a2> D2a 1. In practical situations, the error is sometimes large. Take an example of a Shenzhen Zhongzhen golf club A field A17 hole. The distance from the left side of the hole to the T point is 50 yards, and when a =18 yards, the method codes from the code point D2 to the holes of cups A1, A2, A3 and A4 are 69 yards according to the code number. The distance to A1 was found to be 65 yards, while the distance to A4 was found to be 73 yards.

The second problem is that: all code points with the distance b from the point T have the same distance to the hole cup, and are all d ≈ a + b. Figure 3 shows the case of problem two. In fig. 3, the distances from the track code points D1, D2, D3, D4 and D5 to the point T are all b. The distances are calculated according to the code number method, and the distances D1A1, D2A1, D3A1 and D4A1 from D1, D2, D3, D4 and D5 to the cup A1 are all a + b. This is clearly not correct. The result of this situation is sometimes that the error is large.

Taking the C8 hole in the Shenzhen golf course, there is a 55 yards code point right to the right side of the green. When the hole cup is positioned at the right end of the green, the error can reach more than 10 yards by calculation according to the traditional method.

The above problem, and the player who recognizes in use that the player and his caddy want to make various solutions, is expected to achieve a more desirable result, and thus takes a lot of time for distance determination. Although players and caddies want to make various solutions, they have difficulty in calculating the correct results. Causing confusion to the player and thereby affecting the player's performance. At the same time, the whole event time is prolonged.

In fact, the distance from the track code point to the hole cup cannot be accurately calculated theoretically by adopting the code number method. This is due to the inherent disadvantages of the code counting method. The essence of the method for calculating the distance from the fairway code point D to the green hole cup A by using the code number method can be abstracted as shown in FIG. 4. This problem is itself a mathematical problem. The problem is that: as shown, knowing the lengths of line segments a and b, the distance D from D to A is determined. This mathematical problem is not possible because of the known conditions given, which are not sufficient. That is, the method of using the number of the golf ball tracks requires that the distance d from the code point of the golf ball track to the green hole cup A is not possible at all.

The invention patent application 'a method for calculating the distance from a golf mark point to a cup and a coordinate code book' (application number: 20191136923.9) is an invention on the basis of 'an automatic generation method and system of a golf course hole bitmap' (patent number: CN 201710147170.6).

The patent 'a golf mark point to cup distance calculation method and coordinate code book' proposes a new method for calculating the distance from the fairway code point to the cup. The patented method has been approved by the highest golf authority uk royal ancient golf association R & a, and is deemed to be in compliance with golf rules and may be used. The method solves the problem of calculating the distance from the fairway code point to the cup, but the method calculates the coordinate difference between the fairway code point and the cup in the X direction and the Y direction, and then obtains the distance from the fairway code point to the cup on the green according to the coordinate difference between the X direction and the Y direction by manually searching a golf special coordinate difference distance quick-checking manual. The method still needs to manually calculate the coordinate difference between the track code point and the green cavity cup in the X direction and the Y direction, and needs to search a golf special coordinate difference distance quick-search manual to obtain the distance between the track code point and the green cavity cup. In the method, in addition to calculating the coordinate difference between the track code point and the green cavity cup in the X direction and the Y direction, a player needs to carry a golf special coordinate difference distance quick checking manual and inquire the manual, and the use in the game is inconvenient.

The invention provides a new method based on a golf mark point-cup distance calculation method and a coordinate code book, aiming at overcoming the defects of the golf mark point-cup distance calculation method and the coordinate code book.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The standard golf course is composed of 18 holes, each hole is composed of a fairway and a green, the code point position of each hole forms a coordinate number page, and the hole cup position forms a coordinate hole bitmap. The coordinate digital pages of the 18 holes are combined together to form a coordinate digital book, and the coordinate digital pages of each hole and the coordinate hole bitmap method are the same. The method for designing and calculating the distance from a code point to a hole cup is taken as an embodiment of the invention.

Step one, establishing a unified green lane coordinate system.

A unified lane coordinate system that can describe both lane code points and lane hole cup locations is shown in FIG. 5. The coordinate system can also be considered as a green coordinate system and a fairway coordinate system, respectively. When measuring the green hole cup, the positive direction of Y points to Y for T₁Direction, when measuring the code point of the ball track, the positive direction of the Y axis of the code point is T pointing to Y₂In the direction of (a). Considering the conventional representation of golf right and left, X (R) is the X-axis right direction and X (L) is the X-axis left direction. In fig. 5, the position of the code point D can be described by the coordinates of D in the track coordinate system. And step two, marking the code points of the ball tracks by using the coordinate values.

The coordinate code number method uses the coordinate value of the code point to represent the position of the ball track code point in the ball track green coordinate system. Each hole has a coordinate number page, and the coordinates of the code point of the hole are marked in the code number page. The 18-hole coordinate code number page forms a coordinate code number book. In the coordinate code page shown in fig. 6, the positive direction of the track code point Y is the direction in which T points to the track, and the positive direction of the coordinates of the green hole cup is the direction in which T points directly above. 47/5R in the figure is the code point reference number and also the coordinate value of the code point. Code point 47/5R indicates that the Y coordinate of the code point is code 47 and the X coordinate is code 5 on the right.

And step three, constructing a basic hole cup code book.

When the basic hole cup number book is formed on the basis of the coordinate number book, blank filling frames are reserved at code points in the coordinate number book.

And step four, acquiring a day coordinate hole bitmap.

A bitmap of 18-hole coordinates in a golf course A field of 2020, 12, month, 8 and as shown in Table 1:

in addition, the day-hole bitmap may also be represented as shown in FIG. 8.

And step five, generating a daily cup distance table.

The distance table of the day tunnel cup is formed according to the coordinate code number book and the distance data between the day tunnel code point and the tunnel cup generated by the day coordinate tunnel bitmap. The cup distance table directly gives the distance from the code point to the cup. The day hole cup distance table can be independently used as a hole cup distance table, and data in the table can be expressed in a basic hole cup code book to form a hole cup code book.

A cup distance table formed by cup distances based on a coordinate code number book is shown in Table 2, and the Table 2 is a daily cup distance table of 12 months, 8 days in 2020 and in 12 months in an A1 hole of a certain golf course:

in table 2, the track code point 152/13R is the symbol of the code point, and 152 of the code points indicates that the Y coordinate of the code point is 152 codes, and 13R indicates that the X coordinate of the code point is the right 13 codes.

And step six, generating a daily cup number book.

And filling the data of the number book of the daily cup number in the position of the empty corresponding to the code point of the number book of the basic cup number to form the number book of the daily cup number.

The number of cup codes per day based on the number of coordinate codes is shown in fig. 9. Fig. 9 is a number page of cup codes of 1 st hole 2020, 12 months and 8 days in a certain court.

The distance from the code point to the hole cup is directly given by the distance meter of the day hole cup, and the player can obtain the accurate distance from the code point to the hole cup from the distance meter of the hole cup after finding the reference code point by combining the code number book or the basic hole cup code number book. The hole cup code number book gives the approximate position of the code point on the lane and gives the distance from the code point to the hole cup.

In another aspect, the present invention provides a cup number book, wherein the cup number book is characterized in that the distance from a lane code point to a green cup is calculated by any of the above calculation methods, and the distance from the lane code point to the green cup is represented in the basic cup number book to form the cup number book.
