Background technology
Estimating and the controlling when enjoyment of golf is that with challenge the sportsman hits ball.Because hitting its track of back, ball all can calculate it according to principle of dynamics with distance, if so can design a set of equipment its original speed of energy measurement and azimuth thereof when ball hits, then the movement locus of ball and drop point are all measurable, before the present invention, there are some other designs also once to explore towards this direction effort, but its function is all restricted and defective, the invention that has can only be measured the speed of club rather than the motion of ball itself, the speed that can survey ball that has but can not determine its angle and direction because they can not to provide one be simple and easy and have symmetry and the metering system of integrality.Because ball speed of golf high (surpass 150 kilometers/time) and momentum thereof are very big, so should not measure in the mechanical collision mode, and be suitable for utilizing optical sensing (OPTICAL SENSING), especially form the structure of light net to measure the track of golf with beam array.But present some optical measurement designs are all with the light emitting diode (LED of (DIVERGENT) and incoherent (NON-COHERENT) that disperse, LIGHT EMITTING DIODE) be light source, on long range measurements because of its diversity and low-power with the many difficulties of inevasible experience, add that light emitting diode does not resemble the LASER Light Source that relevant (COHERENT) focuses on (FOCUSED), the projection of each light emitting diode (LED) spot light is with overlapping thereby cause obscuring of acquisition of signal (SIGNALDETECTION) in the application of long distance arrays, improve this defective, each light emitting diode spot light must be focused on or each light source is done the modulation (MODULATION) of individual signal respectively.Moreover when intention utilizes multiple light courcess to form array (ARRAYS), must use a large amount of light emitting diodes, all this kind all will increase the manufacturing cost of product.
Summary of the invention
The objective of the invention is to utilize " relevant laser focusing light source " to produce beam multiplex to overcome above-mentioned difficulty.The polynary beam array that utilizes laser to produce forms the light net (OPTICAL NET) of single symmetry and integrality, can produce an accurate golf training of cover and a game station, and this equipment can be predicted the movement locus after golf hits exactly.
For achieving the above object, the invention provides a kind of equipment (DEVICE) about golf training motion and recreation.Its principle is the motion after utilizing " single plane two-dimensional space, the light net of symmetry and integrality " to survey golf hits, and goes up at display (DISPLAY) and to predict its track.When one of feature of the present invention is that measuring golf hits at first (INITIAL IMPACT) thus speed and the drop point and the track of azimuth prediction ball, another feature of the present invention constitutes the light net of measurement ball speed and angle for utilizing square (SQUARE) or U-shaped framework (FRAMES), wherein a level and a vertical framework are in order to produce laser signal, another corresponding level and vertical framework are then in order to the exploring laser light signal, so combination can form single plane, the symmetry light net of two-dimensional space.In order to save cost and to increase economic efficiency, can use single LASER Light Source, in addition beam split then makes to produce the multi-pass light source to form laser array (or light net).Effective and efficient manner produces secondary light source for utilizing the partial reflection (PARTIAL REFLECTION) that a series of thin glass sheet or quartz plate (QUARTZSLIDE) are placed on fixing distance (less than the diameter of golf) and the angle, nationality helps sheet glass or quartz plate.The laser array of taking this mode and producing can also be applied to touching display screen fields such as (TOUCH SCREEN DISPLAY) except that useful to the measurement of golf spatial movement.In the detection of laser, be to be placed on the fixedly associated frame members on light source opposite by a series of detector (DETECTOR) to finish.The distance of this light net is decided with needing according to every external situation, generally speaking all 0.6 meter to 2.4 meters scope, and can not influence the degree of accuracy of exploring laser light signal.The light net be preferably dimensioned to be 1.2 meters to 2.4 meters square.
In the distally of ball, can install gauze or netting moving on that one side is blocked with the prevention ball by the light net.Obtain the exercise data of ball when the light net after, transferring to a data processor calculates and predicts, and with its result be apparent in one the projection or display on, for interest and the impression that improves the user, can further the scene of bed rearrangement golf course be projected together the movement locus of cooperation ball, to reach simulation and sight true to nature.Because two-dimensional space symmetry of the present invention and accuracy, the motion after ball hit, ball speed, level all can be calculated easily with vertical angle.In order to simplify and to dwindle the size of light net to ask for higher spatial benefit, the present invention can remove the upper end of quadra (FRAME) and form " U " or " II " shape, required space when brandishing to reduce golf club, the structure of taking this overall optical net can contract to minimum, under this kind arrangement, the former laser beam that is as the criterion with the X-Y coordinate will rotate 45 degree, and all elements such as laser secondary light source generator sheet glass (GLASS SLIDE) and detector (DETECTOR) all be located in two vertical frameworks and (or) on the base.

The specific embodiment
Fig. 1 represents side view of the present invention, and batting carpet 1 pendulum on a picture meadow is before square smooth screen frame frame 9, and this light net is to be made up of two groups of parallel with vertical frameworks (FRAME).Be contained in the sensor 2 (SENSOR) on the carpet 1, its purpose is to survey ball is hit moment by club signal.The 3rd, the ball seat of golf driving (TEE) and 4 be golf itself.Axis of reference (REFERENCE AXIS) after the central target line 5 of batting hits as ball.One square light net 9 pendulum are in the place ahead of batting carpet sensor 2 (SENSOR).Launch the vertical frame 10v and the horizontal frame 10h of optical signal, installed light source 12 and the transmitter unit 13a to 13n that produces equidistant secondary light source thereon.Between this secondary light source should be apart from i less than diameter such as the Fig. 2 and the situation shown in Figure 3 of golf.
11v and 11h are the vertical and horizontal frameworks of the optical signal detection (DETECT) relative with penetrating light source, therein Kong partial devices the detector 14 of a series of receiving optical signals, these detectors 14a to 14n is contained in and produces on the corresponding position of secondary light source transmitter unit 13a to 13n, to form the symmetric light net of a two-dimensional space.In the investigative range of this light net, its beam density uniformity (UNIFORM) is not so the degree of accuracy general when calculating the ball motion has any change because of the position of ball.
15a to 15n and 16a to 16n represent the opening of framework light signal last time transmitter unit and optical signal receiving element.Be provided with golf interception net 17 at the rear of light net 9.Data handle with display unit 20 in order to the measurement of announcements with estimate the case of motion of ball, and connect this display unit and light net and the signal cable 18 and 19 (CABLES) between the carpet sensor of batting.One Imaing projector 21 is in order on the interception net that the golf course scene is incident upon ball or the independent screen.
The generation of Fig. 2,3 and 5 explanation optical signals, the mode of beam split and detection.Being provided with laser focused light source 12 is single LASER Light Source beam split is become equal intensities and two vertical light beams with laser light splitter 12a (OPTICAL SPLITER), its purpose, wherein a light beam advances along directional light generation framework 10h, and another light beam then produces framework 10v along vertical light and advances.13Xa to 13Xn produces sheet glass along the secondary light source that parallel framework is installed, and 13Ya to 13Yn produces sheet glass or prism along the secondary light source that vertical frame is installed.These sheet glass or prism are installed on the framework in adjustable mode, and its setting angle is shown the direction 22 of carrying out with respect to light greatly and is miter angle for preferential.
How Fig. 4 description utilizes sheet glass angle and optical coating to reach the branch ray laser to form the multiple beam secondary light source.The multipath reflection that Fig. 5 is caused when describing laser by sheet glass.The angle of each sheet glass is also kept identically because the interval (I) of sheet glass keeps certain, can parallel mode emit with equal strength so produce the multi-stripe laser bundle of secondary light source thus.
14Xa to 14Xn and 14Ya to 14Yn represent the pick-up probe of optical signal, and it is installed in equidistantly with light and produces on the corresponding parallel and vertical frame of framework.These detectors are contained in the sheet glass opposite that produces corresponding to secondary light source and form a symmetric light net of two-dimensional space.As shown in Figure 5, sheet glass that the beam density of this light net is produced by secondary light source and detector number with apart from deciding, and the distance between each light beam is all less than the diameter of golf, because the light net has uniform beam density in its space exploration, so the invention provides the motion that point-device mode is surveyed golf, no matter golf ball is on any detecting location of light net.
As Fig. 4 and shown in Figure 5, except the adjustable angle of secondary light source generation sheet glass is whole, also can utilize other method to modulate the intensity of (MODULATE) each glass flake reflected laser.23 and 24 are representing the optical thin film (antireflection rete) (ANTI-REFLECTION COATING) that is coated with different reflectivity on the surface of two sheet glass sheets.Sheet glass as 23 is plating 2% reflective coating, and then working as intensity is I
oLaser when irradiation, have 2% the laser will be, and have 98% light that transmission is arrived next layer sheet glass by this glass flake reflected.As this 98%I
oLaser when arriving second sheet glass that is coated with 2% reflectivity, then 2% * 98%=1.96%I will be arranged
oLaser be reflected and allow that 98.04% light penetrates.And 24 representing the sheet glass that is coated with 10% reflectivity, and under this kind situation, the first sheet glass sheet will reflect 10%I
oLaser, and the second sheet glass sheet will reflect 10% * 90%=9%I
oLaser.So, utilize the permutation and combination of different reflectivity sheet glass, can set up a complete light net and make the laser beam of each root secondary light source that the identical intensity (INTENSITY) of being close to all be arranged.
Reduce its divergence (DIVERGENCE) in order to make laser keep focusing, thin sheet glass is better than thick.As shown in Figure 5, when laser irradiation sheet glass, will produce a principal reflection (PRIMARYREFLECTION) light I
1And secondary reflection (SECONDARY REFLECTION) light I
2Thin sheet glass 25 will produce less principal reflection and the spacing of secondary reflection (h), to lower dispersing of luminous intensity, receive so the stronger optical signal of tolerable is detected device.By contrast, thicker sheet glass 26 will produce bigger principal reflection and secondary reflection spacing (K), thereby increase the divergence of laser, and the detectable strength per unit area of laser is reduced.In addition, can strengthen light signal strength in addition and reduce the mode that noise (NOISE) disturbs, as utilize special filter (FILTER) that the light source of non-optical signal is filtered out, or utilize the pulse laser of modulating (MODULATION) to increase the detected intensity of optical signal.
Fig. 7,8 and 9 explanations utilize the calculating principle of this two-dimensional space symmetrical beam net (Fig. 6) to ball speed, angle and drop point prediction.As shown in Figure 7,5 central target lines after representing ball to hit, and 28 tracks (TRAJECTORY) after representing ball to hit.When ball is hit by golf clubs, sensor 2 will write down the time t=0 that ball is hit.And be L when ball flies over apart from sensor 2 " during the light net of distance; golf will block the light beam of at least one X-axis with Y-axis; thereby the air coordinates when having determined that ball is by the light net; and the time of this moment is decided to be t=T second; so not only can know golf pass through the air coordinates of light net (X, Y) and ball pass through the flight time T of light net.And, based on these data, the movement locus of ball, takeoff speed V
o, the angle that takes off vertically θ, and level orientation angle (is reference axis with central target line 5) all can calculate and predict.
The floor projection distance of ball movement locus when L ' is t=T among Fig. 7, and the upright projection distance of H ball movement locus when being t=T, L is along the distance of central target line between sensor 2 and light net, W is ball offset distance apart from the central target line when passing through the light net, based on symbol definition as above, can calculate the initial velocity V of ball with following mathematical formulae
o, vertical angle θ and level angle .
And the initial velocity V of ball
oCan be expressed as
With
As shown in Figure 8, the sporting flying track B of ball is decided by the velocity component (COMPONENT) of ball on X-axis and Y-axis, and its velocity component can V

Above Simple Calculation also reckons without under practical situation because air drag, the rotation of ball and the influence of wind speed.But study in great detail and final conclusion is early arranged because these external factors are existing in aerodynamics (AERODYNAMICS), so following these factors can be brought above-mentioned calculating into to promote the accuracy of predicting sphere path curve.
Figure 10,11,12,13,14 and 15 describes the light net that how to make up a single plane two-dimensional space and tool high symmetry and the framework that does not need the top.One is similar to Fig. 1 as shown in figure 10, but the light net that does not have a top frame can be applied to identical golf training purposes, and the light net of this no top frame can be the shape of " U " or " II ".The light net of this no top frame has multiple advantages with respect to the light netting gear that the top frame is arranged.As shown in figure 11, the top framework of square smooth screen frame frame 9 is to cause the biggest obstacle of dwindling the light web frame, its reason is that the top framework stops the action 31 that the golf club 27 of being held by arm 30 swings, so having the light net on top also must be placed on apart from tee 3 length is the top of the place of L with the club bump light net in avoiding brandishing.Like this, the size of light net and the interval between the framework must be strengthened and increase the difficulty of manufacturing, and get rid of and use non-focusing or noncoherent diversity light source.If the top framework can be taken away as shown in figure 11, then the distance of light net and striking point on the ball will be dwindled significantly, thereby the size of light net is contracted to minimum, and even can use non-focusing diversity light source and not influence the degree of accuracy of surveying the ball motion.
To remove the top framework and still keep the single plane two-dimensional space to being referred to as the light net in order to reach, then the arrangement of light beam must be done a rotation as shown in figure 13.This rotation can be rotated the X and the Y-axis (shown on Figure 13) of light net simultaneously, or utilizes the rotation of the spot light cooperation optical axis of diversity.Figure 14 and 15 describes the structure of some possible no top frame light nets.In Figure 13, o'clock (Xi Yj) represents by one group of air coordinates in each space exploration.X and Building Y target angle are vertical 90 degree in Fig. 1 and Fig. 6, but in the structure of this " U " or " II " shape light net, the crossing angle of its optical axis will no longer be limited to 90 degree.The arrangement of this angle can reach by the reflection angle of adjusting secondary light source generator (as sheet glass).As shown in figure 12, be at laser I if secondary light source produces sheet glass
o45 degree angles of reflection on, then X and Y-axis light beam will intersect at vertical 90 degree.If but the reflection angle of sheet glass is 30 degree, then X and Y-axis light beam will intersect at non-perpendicular angle.Like this then the beam arrangement light net can utilize ejaculation or the reflection angle of adjusting secondary light source to be changed.
Figure 14 A describes some possible " U " shapes or is bordering on " U " shape light web frame symmetrically.Figure 14 B is " U " shape structure that is formed by two upright frameworks and a root bottom part framework, its upright framework with the fixed angle of near vertical on the framework of bottom.Each upright framework provides the generation of optical signal or penetrates device X

xThen be installed on the close position of correspondence, its spacing distance is all less than the diameter of golf.The arrangement that this kind optical signal penetrates and receives is able to form the symmetric smooth web frame of single plane two-dimensional space between two vertical frames.
If we use the light source of a diversity to constitute the light net of a large tracts of land two-dimensional space, then resolution of its air coordinates as shown in figure 15 (RESOLUTION) and space exploration all will be affected.But if because of removing top frame light net size is dwindled, then this influence will be reduced to minimum.If the size of light net can be reduced to about 0.6 meter, then utilize the light emitting diode (LEDs) of a series of focusing (but out of phase), or even non-focusing and noncoherent white light (WHITE LIGHT) light source also can form a two-dimensional space light net and keep its detection accuracy the ball motion.So, can increase this product cost benefit in future.
