Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf simulating apparatus and a golf simulating method,

The present invention relates to a golf simulating apparatus and method, and more particularly, to a golfer simulating apparatus and method using brightness and darkness that can intuitively judge the bending of a golf green using a darkness concentration.

As the popularity of golf becomes popular, the number of people who use real golf courses is increasing. However, the frequency of searching for indoor golf courses is increasing mainly for beginners who are uncomfortable with players who do not have time and economical leisure time to go to actual golf courses or who use real golf courses. However, since these indoor golf courses are usually a facility for practicing a long range, players who wish to practice putting have a simple putting practice facility with artificial turf in their home or office and practice here.

However, such a putting practice facility does not have a sense of presence such as a field, and the player performs an operation of putting a golf ball into the hole with only a feeling, thereby giving the player various information (e.g., ), Especially for beginners, does not provide much help when practicing putting.

An indoor golf simulating device capable of practicing putting through a virtual golf green of the present is being developed.

FIG. 1 is a view showing a golf green outputted from a conventional golf simulating apparatus.

The golf simulating device is a device that allows a user to enjoy golf by outputting a virtual golf course to a display device such as a screen.

The shape of the golf green around the hole cup output from the golf simulating apparatus is shown in FIG.

Referring to FIG. 1, in describing the curvature of the golf green, a method of viewing the gradient of the grating method or the grating method is used.

In this conventional method, it is difficult to intuitively judge the curvature of the golf green, and when the grating is enlarged, there is a limitation in showing the curvature between the gratings.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-described problems of the prior art, and it is an object of the present invention to provide a golf ball golf ball, The present invention provides a golf simulating apparatus and a golf simulating method using the same.

Here, the reference height is set to a middle height between the golf ball height and the hole cup height.

Wherein the relative height is between 1 and -1, and the relative height is calculated as follows, wherein the scale value is the maximum height difference with respect to the reference height, and the ground height difference means a height difference relative to the reference height And has a positive value when the height of the ground is larger than the reference height, and a negative value when the height of the ground is lower than the reference height.

The contrast intensity has a value between 0 and 1 and has a value of 0 at the reference height. The closer the relative height is to 1, the brighter and darker the contrast increases, and the closer the relative height is to -1, Concentration increases.

In the case where B is a constant, the image processing unit determines a lightness and darkness to be applied according to the relative height by the following equation.

Here, the B value has a value of 2 or more and 5 or less, and the B value is preferably 3.

The scale value is set in proportion to the distance from the hole cup to the ball.

According to another aspect of the present invention, there is provided a golf simulating method comprising: a first step of setting a reference height corresponding to a darkness of 0; A third step of calculating a relative height by dividing the ground height difference relative to the reference height by the scale value and a third step of outputting the ground surface of the golf green according to the relative height at different darkness levels, And a fourth step of outputting a darker darkness concentration as the relative height is lower.

The golf simulating apparatus and method using the light and dark density according to the present invention as described above is characterized in that the curvature of the 3D golf green is represented by a 2D flat panel display such as a CRT, a projector screen, It is possible to determine the curvature of the golf green intuitively so that it is possible to recognize the golf green more quickly and easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

2 is a block diagram showing a configuration of a golf simulating apparatus according to the present invention.

The golf simulating apparatus according to the present invention includes a database 10 for storing spatial data of a virtual three-dimensional field, a display unit 20 for outputting a 3D golf course, And a processing unit 30.

The database 10 stores three-dimensional spatial data of a virtual golf course. Here, various data including coordinate information, color information, and characteristics of the corresponding feature are stored in the virtual golf course.

The display unit 20 outputs a virtual golf course stored in the database to a user using the golf simulating apparatus.

The display unit 20 may be a 2D flat display device such as a CRT, a projector screen, an LCD, or a PDP. Further, a printing apparatus for printing a golf course map may be included in the display unit.

The image processing unit 30 reads three-dimensional spatial data from the database 10 and outputs the three-dimensional spatial data to the display unit 20, and assigns different darkness levels according to a relative height to a reference height at the time of outputting the golf green Output.

Here, the reference height can be set at a midpoint between the height of the golf ball on the ground and the height of the hole cup. The height of the golf ball or the height of the hole cup may be a reference height. However, in order to sufficiently express the brightness as a whole, it is preferable to select the intermediate point as the reference height. In the present invention, Is set as the reference height.

The image processing unit 30 sets the relative height to a value between 1 and -1, where the reference height refers to a point where the relative height is zero.

Specifically, the relative height can be calculated as shown in the following equation (1).

Here, the relative height is a value obtained by dividing the relative height difference of the ground to be expressed with respect to the reference height by the scale value. In this case, when the height of the ground is higher than the reference height, the height difference of the ground has a positive value. When the height of the ground is lower than the reference height, the ground height difference has a negative value .

If the scale value is 0.5, the area between + 0.5 m and -0.5 m around the reference height is defined as the darkness concentration .

If the scale value is 1, the area between + 1m and -1m around the reference height is expressed as the light intensity.

That is, the scale value adjusts the scale so that the maximum height to be represented by the lightness density corresponds to the relative height 1, and adjusts the scale so that the minimum height corresponds to the relative height-1.

As the scale value becomes smaller, the ground height difference becomes smaller in proportion to the relative height. Therefore, finer darkness representation is possible. As the scale value becomes larger, the ground surface to be expressed by the darkness concentration becomes larger. Therefore, it is difficult to express the difference in height, but the overall bending expression of the wide area is improved.

Here, the scale value can be appropriately determined according to the distance from the hole cup to the ball. For example, when the distance between the hole and the golf ball is short, the scale value can be set to a small value to enable detailed shading. When the distance between the hole cup and the golf ball is long, the scale value can be set large, .

For example, the scale value may be set in proportion to the distance from the hole cup to the ball.

In the present invention, the image processing unit 30 expresses the ground so that the light and dark densities vary with the relative height.

The lightness and darkness values have a value between 0 and 1, and have a lightness and darkness of 0 at the reference height.

That is, at the reference height, the ground surface is expressed by the color of the basic field green.

If the relative height is closer to 1, the contrast is set close to 1. In this case, the increase in the contrast increases the brightness. Conversely, the closer the relative height is to -1, the closer the contrast is set to 1, but in this case, the increase of the contrast increases the brightness.

That is, the closer the relative height is to 1, the brighter, and the closer the relative height to -1, the darker the representation.

The maximum and minimum absolute darkness values can be 255 and 0 for 256 gray levels. That is, the reference height is represented by a gray level of 122 or 123, which is an intermediate value, and when the relative height is increased from 0 to 1, the brightness is increased from 122 or 123 to 256, and the relative height is decreased from 0 to -1 , The brightness is decreased from 122 or 123 to the 0 level.

In this case, in the present invention, the maximum value and the minimum value of the absolute brightness and darkness may be expressed as arbitrary intermediate values instead of 255 and 0, respectively.

That is, the top point may be represented as a slightly darker value than white, and the lowest point may also be represented as a slightly brighter value than black. In other words, the range of brightness values can be appropriately adjusted.

FIG. 3 is a graph showing the relationship between the contrast concentration and the relative height according to the present invention.

In the present invention, the intensity of light and dark may be set to change linearly according to the relative height from 0 to 1, but it may be set to change to a constant curve form as shown in Equation (2) below.

In other words, it is possible to make the distinction of contrast more detailed at the midpoint than at very high or very low areas. In golf greens, very high or low areas in the space from ball to hole cup are rare, and curvature is formed at a middle height set mainly to the reference height, to be.

Here, it is preferable that B is a value of 2 or more and 5 or less, but more preferably, B is set to 3.

In the case of FIG. 3, when B is 3, the graph shows the relationship between the contrast and the relative height. Even if there is only a slight height difference in the middle area near the reference height, Can be recognized more easily.

FIGS. 4 and 5 are views showing a golf green to which a light and dark concentration is applied according to the present invention.

In FIGS. 4 and 5, not only the contrast but also the lattice curvature are shown.

Referring to FIGS. 4 and 5, it can be seen that a place where the altitude of the ground is higher than the reference height is brightly displayed, and a place where the altitude of the ground is lower than the reference height is displayed dark.

Here, since the curvature of the ground is continuous, it can be seen that the light and dark changes from the high altitude to the low altitude are continuous.

In addition, it is possible to know the direction of the slope of the ground through the formation of a slope from a light-bright place to a low place, and it is possible to sense how urgent the slope is by whether the change of the light / shade is abrupt.

The user can intuitively grasp the curvature of the ground of the green from such a shadow display, thereby enabling more accurate putting.

FIG. 6 is a flowchart showing a golf simulating method to which a contrast concentration is applied according to the present invention.

First, a reference height corresponding to a darkness level of 0 is set (S10).

Here, the reference height is set to a middle height between the height of the golf ball and the height of the hole cup.

Next, a scale value which is a maximum height relative to the reference height is set (S20).

Here, the scale value can be appropriately determined according to the distance between the hole cup and the ball. For example, when the distance between the hole and the golf ball is short, the scale value can be set to a small value to enable detailed shading. When the distance between the hole cup and the golf ball is long, the scale value can be set large, .

For example, the scale value may be set in proportion to the distance from the hole cup to the ball.

Next, the relative height is calculated by dividing the ground height difference relative to the reference height by the scale value (S30).

Here, the relative height has a value between 1 and -1, and the ground height difference has a positive value when the height of the ground is larger than the reference height, and when the height of the ground is lower than the reference height, .

Next, the ground surface of the golf green is output according to the relative height with different lightness levels, and as the relative height is increased, the lightness and darkness levels are output. .

Here, the light / dark concentration has a value between 0 and 1, and has a value of 0 at the reference height. The closer the relative height is to 1, the brighter and darker the contrast increases. The closer the relative height is to -1 Dark contrast increases.

The intensity of light and darkness is calculated as shown in Equation (2), where B is preferably 2 or more and 5 or less, and more preferably, B may be 3.

When non-linearly non-linearly assigning the lightness and darkness to the relative heights, the difference in lightness and darkness is greater even if there is a slight height difference in the middle region near the reference height than at both ends.

Although the present invention has been described with reference to the exemplary embodiments of the invention, it should be understood that the invention is not limited to the disclosed embodiments, Can be applied.
