Abstract

A method for describing the positions of golf putting green hole cups and a coordinate hole map. The method comprises: describing the exact positions of hole cups in a putting green by using putting green coordinates; describing the relationships between ball holes and the edges of the putting green by using the distances from the ball holes to horizontal and longitudinal edges of the putting green; and then forming a golf coordinate hole map. The method overcomes the shortcomings in which the positions of the hole cups described in the existing hole map only have the longitudinal coordinates of the putting green and do not have the horizontal coordinates of the putting green, and the relationships between the hole cups and the edges of the putting green that are described only have the distances between the hole cups and the horizontal edges of the putting green, and do not have the distances between the hole cups and the longitudinal edges of the putting green; and the method fundamentally solves the problem of accurately describing the positions of the golf putting green hole cups in the putting green.

Description

A method for describing the position of a golf green hole cup and a coordinate hole map

Technical field

The invention relates to the field of golf sports, in particular a method for describing the position of a golf green hole cup and a coordinate hole map.

Background technique

At present, the hole map of all golf events in the world is formed in the following way. Namely: first set the front and back points of the green, the front point is usually marked with T or dot, and the back point is usually marked with dots. The line between the front and the back of the green is used as the vertical coordinate of the green, and the front point T of the green is drawn along with the vertical axis of the green. The green front edge line with vertical coordinates is used as the abscissa of the green coordinates, and the front point T of the green is the origin of the green coordinates, forming a green coordinate system.

Usually one day before a round of competition, a position is selected for each hole as the hole cup position. After the location is determined, measure the location of the location on the green. When measuring, take the vertical axis of the green coordinate system as the vertical reference line and the horizontal axis of the green coordinate system as the horizontal reference line, and measure the distance from the cup point of the hole to the abscissa of the green on the parallel line. Measure the distance from the cup point of the hole to the lateral proximal edge of the green. From this, draw a hole map describing the position of the hole cup in the green. An example of the hole position diagram formed in this way is shown in Fig. 1, which is an 18-hole green hole diagram of a course for a certain round of an international golf competition. Figure 2 is the location map of one of the green holes.

It can be seen from Figure 2 that such a hole map only describes the ordinate of the hole cup from the green coordinate, that is, the ordinate of the hole cup is 12. The abscissa is not given. This method cannot describe the exact position of the hole cup in the green coordinate system.

The representation of the hole position map shown in Figure 2 describes the distance between the hole cup and the proximal edge of the green only in the lateral direction of the green, that is, the distance between the hole cup and the left edge of the green is 6, but does not describe it. The distance between the cup and the longitudinal proximal edge of the green. This description is incomplete.

This kind of hole map that only describes the distance between the hole cup and the horizontal edge of the green. When the player needs to know the distance between the hole and the longitudinal edge, it cannot provide the player with the information about the hole cup and the vertical edge of the green.

There are two main purposes for describing the position of the hole cup in the green; one is to describe the accurate position of the hole cup in the green coordinate system, and the other is to describe the distance between the hole cup and the lateral and longitudinal proximal edges of the green. Describe the role of the hole cup in the coordinates of the green coordinate system.

It is convenient for players to calculate the distance from the fairway code point to the green hole cup based on the distance from the fairway code point provided by the code book to the green front point T and the position of the hole cup on the green provided by the hole map. Since the above hole map does not describe the abscissa of the hole cup in the green, it is uncertain to calculate the distance between the code point and the hole cup based on the hole map information described in this way. Describe the distance between the hole cup and the horizontal and longitudinal proximal edges of the green to provide golfers with the distance to the edge of the hole. However, when the current hole map describes the distance between the cup and the edge of the green, the existing hole map only describes the distance from the horizontal edge of the green, but does not describe the distance from the longitudinal edge of the green. This description is incomplete.

The coordinate hole map method and coordinate hole map proposed by the present invention overcome the shortcomings of the existing hole map, and completely describe the accurate position of the hole cup in the green, and the distance between the hole cup and the green lateral and longitudinal proximal fruit The distance from the edge of the ridge can provide an accurate basis for the golfer to calculate the distance from the fairway code point to the hole cup, as well as provide information on the distance from the horizontal and vertical proximal edges of the green.

Summary of the invention

S103. Draw a line perpendicular to the ordinate Y of the green after passing the front point T, which is called the green front edge line to form the abscissa X of the green to complete the establishment of the coordinate system.

Further, the specific coordinates of the cup marked in step S2 are:

S201. The coordinates of the hole cup are indicated by letters and numbers, the letters indicate the direction, and the numbers indicate the distance; S202, the hole cup is indicated by L (Left) on the left side of the Y axis, and R (Right) on the right side of the Y axis; before and after the green The edges are represented by F (Front) and B (Back) respectively.

Further, step S3 is specifically:

After the cup is determined, the green coordinates will be used to accurately describe the abscissa and ordinate positions of the cup on the green; the distance between the cup and the edge of the green is used to describe the distance between the cup and the edge of the green; in describing the cup When the distance from the edge of the green, it is necessary to describe the distance between the hole cup and the horizontal edge of the green and the distance between the hole cup and the longitudinal edge of the green to make the edge description of the hole cup more complete.

On the other hand, the present invention provides a coordinate hole map describing the position of a golf green hole cup, which is characterized in that it is made according to any method of claims 1-4, and the coordinates of the hole cup in the green coordinate system are obtained by , And the distance between the hole cup and the horizontal and vertical edges of the green to generate a coordinate hole bitmap.

Further, the coordinate hole map is characterized in that the coordinate hole map includes, but is not limited to, an electronic file format or a printed matter format.

Further, the representation form of the coordinate hole map includes, but is not limited to, a schematic diagram or a real green map.

The beneficial effect of the present invention is that it overcomes the problem that when the traditional hole map describes the position of the hole cup in the green coordinate system, only the longitudinal coordinates are given but the horizontal coordinates are not given, so it fails to accurately describe the hole cup on the green. The problem of accurate position in the coordinate system. The present invention accurately describes the position of the hole cup in the green coordinate system, and provides the horizontal and longitudinal coordinate values of the hole cup in the green coordinate system, so that it is possible to accurately calculate the distance from the fairway code point to the hole cup. The invention also overcomes the shortcomings of the traditional hole map describing the distance between the hole cup and the edge of the green and only describes the distance between the hole cup and the proximal edge of the green, but not the distance between the hole cup and the longitudinal edge of the green, and fully describes the green hole. The distance from the cup to the horizontal and vertical edges of the green provides golfers with complete information about the distance between the cup and the edge of the green.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The standard golf course consists of 18 holes, each of which consists of fairways and greens. There is a ball on the greens. During the game, the position of the hole on the green changes every day. In order to describe the position of the hole cup on the green and the distance between the hole cup and the edge of the green, each hole needs a coordinate hole map to describe the situation of the hole cup on the green. There are 18 hole maps for the 18 holes, and the coordinate hole map for each hole is implemented in the same way. Here, the design and representation method of the coordinate hole map of a certain hole in a certain course is taken as an embodiment of the present invention.

In a specific embodiment, the steps are as follows:

Step 1. Establish a green coordinate system.

Determine a point at the front of the green as the front point of the green, and mark it as point T. Then determine a point on the back edge of the green as the back point of the green and mark it as the T1 point. The connection of the two points forms a line connecting the front and back points of the green to form the ordinate T of the green coordinate system. Pass the front point T and draw a line perpendicular to the green ordinate Y, which is called the green front edge line, forming the green abscissa X. Point T is the origin of the green coordinates. The green coordinate system constructed in this way is shown in the figure below.

In Figure 3-4, the hole cup is represented by L (Left) on the left side of the Y axis and R (Right) on the right side of the Y axis. The left and right edges of the green are represented by L (Left) and R (Right) respectively. The front and back edges of the green are represented by F (Front) and B (Back) respectively.

Step 2: Description of the hole cup and representation of the coordinate hole map.

Usually one day before a round of competition, a position is selected for each hole as the hole cup position. For the convenience of discussion, the position of the hole cup is point A.

After the hole cup is determined, the green coordinates will be used to accurately describe the position of the hole cup on the green on the abscissa and ordinate. Use the distance between the cup and the edge of the green to describe the distance between the cup and the edge of the green. When describing the distance between the hole cup and the edge of the green, it is necessary to describe the distance between the hole cup and the horizontal edge of the green and the distance between the hole cup and the longitudinal edge of the green to make the edge description of the hole cup more complete. The complete description of the position of the hole cup can be represented by the graphical representation of the coordinate hole bitmap shown in Figure 4. In the figure, the coordinates (12, L11) accurately describe the position of the hole cup in the green coordinates where the ordinate is 12 and the abscissa is 11 on the left. (F6, L6) accurately describes the distance between the hole cup and the front edge and the left edge of the green as 6 meters from the front edge of the green and 6 meters from the left edge of the green.

It can be seen from the figure that the coordinate hole position map is clear and fully describes the position of the hole cup in the green coordinate system and the distance between the hole cup and the edge of the green. The coordinate hole bitmap can also be represented by letters and numbers. The markable hole bitmap in the above figure can be expressed as ((12, L11), (L6, F6)), the first group of data is the coordinate value of the hole cup in the green coordinate system, and the latter group of numbers is the hole cup distance The distance between the horizontal and vertical edges of the green.

Step 3: Example of coordinate hole bitmap.

According to the above method, the distance between the green hole cup and the horizontal edge and the longitudinal edge of the green is obtained by using the green coordinate system direction as a reference. Coordinate hole maps of other greens of the 18-hole golf course can be obtained. Figure 3 shows the 18-hole coordinate hole map of a certain round of a golf event. Figure 4 is a hole map of one of the holes.

The above are only the embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the description and drawings of the present invention, or directly or indirectly applied to other related technologies In the same way, all fields are included in the scope of patent protection of the present invention.
