DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to explain the present invention in detail so that those skilled in the art can easily carry out the present invention. . Other objects, features, and operational advantages of the present invention, including its effects and advantages, will become more apparent from the description of the preferred embodiments. It should be noted that the same reference numerals are used to denote the same or similar components in the drawings.

FIG. 2 is a configuration diagram of a home golf system using a ray pattern image according to an embodiment of the present invention, and FIG. 3 is a plan view of a swing bottom according to an embodiment of the present invention.

The present invention can be applied to a golf swing system including a swing bottom surface 200, optical sensors 211 and 212, a speed display window 220, a laser golf club 100, a swing image sensing unit 300, a swing information calculation unit 400, 500, and a screen golf display unit 600.

The swing bottom surface 200 is a surface on which the swinging of the laser golf club 100 is performed and passes over the swing bottom surface 200 to swing the laser golf club 100. The user of the home golf system using the light beam pattern image of the present invention assumes that there is a hypothetical golf ball at the center of swing bottom surface and swings the laser golf club 100 while sweeping over the center point of the swing bottom surface 200 swing.

3, a horizontal first guiding line L1 and a second vertical guiding line L2 orthogonal to the center point are indicated on the swing bottom surface 200 and a second guiding line L2, The type of the club may be indicated in. At the center point of the swing floor 200, a circle having a size of a golf ball is displayed so that the user can recognize the golf ball as a virtual golf ball.

The optical sensors 211 and 212 are provided with a first optical sensor 211 positioned at the center of the swing bottom surface and a second optical sensor 212 located at a center point of one side of the swing bottom surface. The first optical sensor 211 and the second optical sensor 212 can measure the swing speed of the pattern image emitted from the laser golf club. That is, the user of the screen golf system passes the virtual golf ball marked on the bottom of the swing floor to two upper sides of the optical sensors 211 and 212 of the swing floor 200, and swings the laser golf club 100 swing. The two light sensors 211 and 212 at regular intervals sense the pattern image P emitted from the laser golf club 100 and use the time interval of the pattern image perceived by each photosensor to adjust the speed of the club to the speed display window 220).

The speed display window 220 is provided on the bottom surface of the swing and displays the moving speed of the pattern image measured through the optical sensors 211 and 212.

The laser golf club 100 includes a gripper body 110 and a laser pointer 120 coupled to an end of the gripper body 110, not a real object such as a wood or iron. The laser pointer 120 provided at the end of the clasp 110 emits a pattern image P. [ The image of the pattern image P can be moved by moving the photographing range of the image sensing unit 300 installed on the upper side of the swing floor 200 by the swing of the user holding the laser golf club 100. [ Accordingly, the motion speed and shape of the circular pattern image P can be photographed by the image sensing unit 300. [

The pattern image P can be a circular pattern as shown in Fig. 4, which includes an outer circle P0, a first diameter line P1 horizontally intersecting the center point of the outer circle as the diameter of the outer circle, And a second diameter line P2 which is perpendicular to the first diameter line P1 and crosses the center point of the outer circle as the diameter of the outer circle P0. Hereinafter, a diameter line in the same direction as the swing direction of the laser golf club is referred to as a first diameter line P1, and a diameter line in a direction perpendicular to the swing direction is referred to as a second diameter line P2.

For reference, the present invention will be described by taking a circular pattern image as an example, but it will be obvious that a square pattern or the like can be applied even if it is not a circular pattern.

The swing image sensing unit 300 is provided at the upper side of the swing bottom surface to photograph the moving speed displayed on the speed display window 220 and photographs the pattern image at the center point of the swing bottom surface to detect the changed state of the pattern image . At this time, the timing at which the pattern image is photographed is synchronized (TRIGGER) so that the pattern is photographed when passing through the first optical sensor 211 installed in the center of the swing bottom plate 200

The swing image sensing unit 300 may be realized by various image acquisition means such as a camera. For reference, the camera may include a lens assembly, a filter, a photoelectric conversion module, and an analog-to-digital conversion module. The lens assembly includes a zoom lens, a focus lens, and a compensation lens. The focus distance of the lens can be shifted under the control of the focus motor MF. The filters include an optical low pass filter and an optical low pass filter. And may include an Infra-Red Cut Filter. An optical low-pass filter removes the high-frequency component of optical noise, while the Infra-Red cut filter blocks the infrared component of incident light. The photoelectric conversion module may include an image pickup device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor). The photoelectric conversion unit OEC converts light from the optical system OPS into an electrical analog signal. The analog-to-digital conversion module may include a CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) device. An analog-to-digital conversion module (not shown) processes an analog signal from the photoelectric conversion unit OEC, removes the high-frequency noise, adjusts the amplitude, and converts the analog signal into a digital signal.

The swing information calculation unit 400 calculates swing speed, swing angle, and club head type at the swing of the laser golf club using the changed state of the pattern image. When the circular pattern image P at the time of swing is received by the first optical sensor 211 at the center point of the swing bottom surface 200, that is, at the time of impact, You can calculate the swing speed, club swing angle (club angle, club alignment angle), and club head type.

The movement speed of the circular pattern P changes depending on the swing speed when the laser golf club 100 is gripped and swung and the shape variation amount of the circular pattern P varies depending on the degree of inclination of the laser golf club 100 It is possible to calculate the velocity of the club during swing, the angle of approach of the club, the angle of alignment of the club, and the type of club head using the above characteristics. For reference, when the laser golf club 100 is swung, the shape of the circular pattern P on the swing bottom surface 200 changes according to the swing direction as shown in FIG.

The swing speed calculation of the laser golf club 100 in the swing information calculation unit 400 is determined by the sensing time of the pattern image P sensed between the two optical sensors 211 and 212. That is, according to the speed at which the user grasps and swings the laser golf club 100, the detection of the pattern image P detected between the center of the swing floor 200 and the two optical sensors 211, Time will vary. For example, when the user swings fast on the swing bottom surface 200 while grasping the laser golf club 100, the time interval of the pattern image P sensed by passing through the upper side of the optical sensors 211 and 212 When the user swings slowly on the swing bottom surface 200 while grasping the laser golf club 100, the time interval of the circular pattern P sensed by passing over the optical sensors 211 and 212 is slow will be.

The first optical sensor 211 installed at the center of the swing floor 200 and the second optical sensor 211 installed at the center of the swing bottom surface 200 are arranged on the basis of the moving direction of the circular pattern P when the swing of the laser golf club 100 is performed, The velocity can be determined using the time at which the laser beam is sensed and the distance between the sensors. Can be calculated by the following equation (1).

[Equation 1]

Head speed = distance between two photosensors / time difference perceived by optical sensor

Accordingly, the interval of the perceived time of each optical sensor is converted into a speed using the distance of the optical sensor, and is displayed as a number in the speed display window 220 at the lower center of the swing floor 200. The swing imaging sensor 300 Excludes images of numbers

The calculation of the kind of the club head in the swing information calculation unit 400 may be performed by using the circular pattern image in the vertical direction perpendicular to the moving direction of the pattern image P when the swing of the laser golf club 100 is performed The club head type is calculated by finding the lie angle unique to the club in relation to the two lengths of the second diameter line P2 separated by the first diameter line P1 which is the horizontal line inside the outer circle P0 of the club . The variation amount of the pattern image P sensed by the degree of tilting of the laser golf club 100 by the user will be varied. For example, as shown in FIG. 4A, when the user does not tilt the gripper 110 of the laser golf club 100 much, the laser pointer 120 emitted from the laser pointer 120 provided at the end of the gripper 110 The circular pattern image P becomes close to a circle. On the other hand, as shown in FIG. 4B, when the user tilts the gripper 110 of the laser golf club 100 more than in FIG. 4 (b), the circular pattern image P is closer to the ellipse than the circular shape As shown in FIG. 4 (c), when the user tilts the gripper 110 of the laser golf club 100 more than that of FIG. 4 (b), as shown in FIG. 4 c). < / RTI >

At this time, the slope of the laser golf club is formed differently for each club by its own lie angle, which is the angle between the club and the ground. Therefore, the change of the pattern image P is performed when the second diameter line P2 in the pattern is two (h1, h2), it is possible to find out the lie angle between the ground and the golf club, so that the kind of the club can be excluded. The lie angle of an actual golf club corresponding to Figs. 4 (a), 4 (b) and 4 (c) is shown in Fig.

4, the laser golf club 100 can be grasped and swung with different slopes. As a result, as shown in FIG. 4, the movement direction (swing direction) of the pattern image P and the vertical The relationship between the second diameter line P2 of the vertical direction and the second diameter line length h1 and h2 separated by the first diameter line P1 which is another inner horizontal line You can determine the club head type by identifying the lie angle and assigning it to the unique lie angle of each golf club.

Generally, in the case of an iron of a golf club, as shown in FIG. 10, it has kinds of iron 3, 4, 5, 6, 7, 8, 9 and pitching wedge according to the shape of the iron head. The wood (driver) of a golf club also has wood types 1, 3, 4 and 5 according to the head shape. The direction and distance of movement of the golf ball can be changed depending on the shape of the head of the iron or wood in the golf practice.

Therefore, the value of the golf simulation result varies depending on what type of iron is used when playing golf on the golf screen, so that the kind of the club head is calculated.

In a golf practice, a 7 iron would swing less than a 3 iron due to the shape characteristics of the head, and the lower the iron number, the more the golfer tends to swing. The kind of the club head is calculated by using the head characteristic.

Assuming that the inclination degree of the gripper 110 of the laser golf club 100 has the first slope <second slope <third slope, the first slope is the least inclined and the third slope is the most inclined, when the gripper 110 of the laser golf club 100 is inclined at the first inclination as shown in Fig. 1 (a), the first circular pattern P in the outer circle P0 of the circular pattern P in the vertical direction perpendicular to the swing direction Two different lengths h1 and h2 separated by the diameter line can be calculated. 4 (b), when the gripper 110 of the laser golf club 100 is inclined at the second inclination, the first diameter (horizontal line) in the outer circle P2 of the circular pattern image P The lengths h1 and h2, which are two different second diameter lines separated by the line P1, can be calculated. As shown in Fig. 4 (c), when the gripper 110 of the laser golf club is inclined at the third inclination, two different lengthwise vertical lines separated by the first diameter line of the circular pattern image P (h1, h2) can be calculated

Therefore, the length of two vertically separated lines according to the slope of the club has a functional relationship. Therefore, it is possible to grasp the kind of the club head by using the lengths (h1) and (h2) lengths of the vertically separated lines of the circular pattern (P) in the vertical direction perpendicular to the swing direction. The ray angle can be calculated by the following equation (2), where the irradiation angle is an angle indicating the irradiation range of the laser emitting light in the laser golf club.

&Quot; (2) &quot;

 (Angle of incidence) = arctan (((h1 + h2) / (h1-h2)

For reference, after assigning and storing the unique lie angle and loft angle of the club head in the screen golf simulation part, the game player selects the desired club in the screen golf simulation part and measures the lie angle of the head measured by the swing of the club To determine if you swing using a normal club. For reference, the loft angle is shown in Fig.

On the other hand, the swing information calculation unit calculates the swing angle, and the swing angle may include an angle of incidence of the head, a state of separation from the bottom surface, and an alignment angle of the head. Hereinafter, a calculation example will be described.

1. Calculation of head angle of entry

The swing information calculation unit 400 calculates the entering angle of the head of the laser golf club based on the moving direction (swing direction) of the pattern image P when the swing of the laser golf club 100 is performed, The first diameter line in the outer circle P0 of the pattern image P at the time point is divided into two with the middle point as a reference and the swing entering angle can be calculated using these two lengths h3 and h4.

6A, when the user swings the gripper 110 of the laser golf club 100, the laser pointer 120 (see FIG. 6A) provided at the end of the gripper 110 along the head moving direction The circular pattern image P emitted by the light source is close to an elliptical shape at the time of entry, changes to a circular shape at the time of impact, and becomes elliptical at the FOLLOW SWING. However, as shown in Fig. 6 (b), two points (h3, h4) are shown with different lengths with reference to the midpoint of the first diameter line L1 which is the horizontal line of the circular pattern. That is, h3> h4 at the time of entry, h3 = h4 at the time of impact, and h3 <h4 at the time of FOLLOW SWING. At this time, the entering angle of the head can be calculated by using the lengths of h3 and h4.

As a result, the first diameter line P1, which is a horizontal line in the outer circle P0 of the pattern image P in the moving direction of the pattern image P, is a length separated from the second diameter line P2 Therefore, the swing angle is different. Herein, the swing entry angle is set such that the laser golf club 100 is added to the club's unique loft angle (e.g., driver: 10,5, s / w56, etc.) blow [Figure 6-c], and Upward [Figure 6-d]

The entry angle at this time can be obtained by the length of the h3 and h4 separated from the first diameter line P1 of the pattern image P and the irradiation angle of the pattern, and in addition to the loft angle unique to the club type selected by the player, Can be determined. The entry angle calculation expression is expressed in the following equation (3).

&Quot; (3) &quot;

(Entrance angle) = arctan ((h3 + h4) / (h3-h4)) * tan (irradiation angle * 0.5)) - 90

2. Calculating the separation from the floor

Is a measure of how far the laser pointer 120 is spaced from the swing floor 210 of the swing floor 200 and refers to the distance between the ground and the club head at the time of actual golf kicking. For example, as shown in FIG. 7 (a), when the laser pointer 120 of the laser golf club 100 passing over the swing bottom surface 210 is positioned close to the swing bottom surface 210 and swings The length P2 'of the second diameter line L2 located within the outer circle P0 of the pattern image P is determined as shown in Fig. 7 (b).

However, as shown in FIG. 8 (a), the laser pointer 120 of the laser golf club 100 passing over the swing bottom surface 210 is located farther from the swing bottom surface 210 than the laser pointer 120 of FIG. 7 (a) Is determined as the length P2 of the second diameter line L2 of the outer circle P2 of the pattern image P as shown in Fig. 8 (b). In the laser golf club 100, P2 '"as the distance between the laser pointer 120 and the swing floor 210 of the laser pointer 120 increases. Therefore, since the length of the second diameter line P2 inside the outer circle P0 of the circular pattern image P in the swing direction is different from the length of the outer diameter circle P2 of the outer circle P0 of the pattern image P, The distance between the laser golf club 100 and the swing bottom surface 210 can be calculated using the length of the two diametrical lines.

The distance between the laser golf club 100 and the swing bottom surface 200 is specified and stored using the length of the second diameter line P2 of the pattern image P0 in the swing direction, The distance between the normal head of the swing and the ground can be checked to the extent that the length matches the length of the second diameter line P2 of the pattern image P to be measured.

The gap between the laser golf club 100 and the swing bottom surface 200 (club and swing bottom surface) can be found using the following equation (4). In other words, we use the lie angle based on the already known survey angle and pattern analysis. In other words, the following equation can be introduced by finding the angle between the upper and lower partial light rays of the second diameter line P2 shown in FIG.

&Quot; (4) &quot;

(G) = (length of upper vertical line in the circular pattern (h1) / sin (irradiation angle * 0.5)) * sin (angle between the club and the bottom surface)

That is, the change in the length of the upper vertical line in the circular pattern affects the spacing between the club and the floor, so that the change in the gap can be detected.

3. Calculate the alignment angle of the club head

The alignment angle of the club head is a measure of alignment when the head is impacted.

A first guide line L1 and a second guide line L2 which are horizontal with respect to the center point of the swing bottom surface 200 and a second guide line L2 perpendicular to the center point of the swing bottom surface 200, The pattern image P is irradiated with the second diameter line P2 which is a vertical line of the pattern image P of the laser golf club 100 with the second guide line L2 of the swing bottom surface 200 You can figure out the angle of alignment of the club head by finding the angle.

On the swing floor 200, guide lines that are the first guide line and the second guide line are displayed based on the impact point of the virtual golf ball. It is possible to analyze the alignment angle of the club head by analyzing the changed image of the pattern image irradiated on the swing bottom surface 200.

Fig. 9 (a) shows the head in the open state, and Fig. 9 (b) shows the head in the closed state. 9A is an image of the swing bottom surface 200 and the irradiated pattern image P. The intersection point of the second guide line L2 on the bottom surface of the swing and the outer circle P0 of the pattern is X1 and the intersection point of the second diameter line P2 of the pattern and the outer circle P0 is X2 , The length between X0 and X1 is Y1, the length between X1 and X2 is Y2, and the length between X0 and X2 is Y3, the following formula (5) can be obtained.

&Quot; (5) &quot;

Head alignment angle = arccos ((Y1 ² + Y3 ² -Y2 ² ) / 2 * Y1 * Y3)

On the other hand, the screen golf simulation section reflects the motion of the virtual golf ball by the calculated swing speed, the swing angle (the entering angle of the head, the distance from the bottom surface, the alignment angle of the head) Simulate. The simulation of the screen golf image may utilize various screen golf simulations known in the art. For example, the swing information calculation unit 400 receives the swing speed, the swing angle (the angle of approach of the head, the distance from the bottom surface, the alignment angle of the head) and the club head type provided by the swing information calculation unit 400, Accordingly, it is possible to generate a screen golf image which is a moving image of a golf ball in a virtual three-dimensional golf field.

The screen golf display unit 600 is a display means for displaying and displaying the generated screen golf images. The screen golf display unit 600 may be implemented as a TV monitor such as an LCD or an LED, or may be implemented as a touch screen panel capable of simultaneously performing input and display. For reference, the touch screen panel is not only a screen display means but also an input means for sensing a touch by touch means such as a touch pen or a finger. For reference, the touch screen panel may be implemented by a touch panel of any one of a resistance film type, a capacitive type, an infrared type, and an ultrasonic type. The touch panel is a transparent switch panel that can control a device by directly pressing a place where a sentence and a picture are displayed in combination with a CRT or an LCD.

The technical idea of the present invention is not necessarily limited to or limited to these embodiments Various changes, modifications, and other equivalent embodiments are possible without departing from the spirit of the present invention.
