Description
Technical field
The present invention relates to a kind of for determining the movement characteristic related to club square stance golf swing (including Gao Er
Husband's ball spiral feature) system and device.Present invention relates particularly to but be directed not only to a kind of such method and apparatus, methods described
The reason for including analyzing these ball spiral features;Described device fully or largely automatic running, without technical staff or
Expert helps.
Following prior art documents are disclosed for the movement characteristic (including rotational characteristics) that determines golf driving
Device.
US 4,136,387, US 5,471,383, US 6,592,465 and US 20040030527 are disclosed and can passed through
The geometric position or size of permanent marks or mark on sphere between two or more consecutive images of sport ball are analyzed with processor
Change to determine the device of spiral feature.Image is caught by one or more high-speed camera.But these systems are in some sides
There is inherent limitation in face, especially these systems determine that the accuracy or reliability level of side spin parameter is very low, because side
The mark or mark that spiral is produced are very small compared with mark or mark that chop is produced.Also there is following limitation in these systems
Property, i.e., golf needs to carry out signalment and guarantees these marks of positioning or indicate so as to detect in the picture
These marks are marked.These systems can not distinguish angle spiral and eccentric spiral.This specification is following by definition and explains
Angle spiral and eccentric spiral.
Some systems of similar said system attempt the ball for avoiding using signalment.The B2 of US 7,292,711 are disclosed
A kind of system similar to said system, wherein, signalment or mark are not detected, but detect natural surface mark, such as ball
The stain on surface, cut channel or indenture.US 2006/0046861 discloses a kind of system, wherein, interim heat label is detected, rather than
Signalment.But it is believed that these systems can not work in practical situations both.Even if additionally, these systems can be in reality
In the case of work, can not overcome it is determined that because accuracy or reliability are very low, other of correlation limit to during side spin parameter
Property, and cannot distinguish between angle spiral and eccentric spiral.
US 2002/0107078 and the B1 of US 6,224,971 are disclosed can be caught on golf by radar system
The contrast reflected signal for being done determines the device of spiral feature.Reflected signal is analyzed by processor, to determine spiral feature.
But these systems can not measure spiral axle and side spin.These systems can not distinguish angle spiral and eccentric spiral.Another office
Limit is that golf can not carry out significantly angle spiral in measurement process, and this needs contour to low speed spiral, a rod batting
Speed batting carries out relatively long distance tracking, therefore can not use closely net.Need also exist for providing special on golf
Make golf before reflecrtive mark and batting in limitation such as specific direction orientations.
US 20090075744 discloses a kind of radar installations, and it passes through radar signal and (including is equally spaced in frequency
Frequency vestige) frequency analysis determines the methods such as spiral speed, and spiral parameter is just can determine that without using special reflective marker.The dress
Put and can also overcome and can not detect side spin this limitation by determining that golf ball flight trajectory is individually determined spiral axle.But
But there are some other limitation in the system.One of them is exactly that it is only used when long-distance flight trajectory is tracked, therefore
Can not indoors using or use when tapping ball into net.Another limitation is exactly the landscape condition that has not counted may influence mode class
The trajectory of spiral generation is similar to, causes the related spiral parameter of determination inaccurate.Another limitation be cannot distinguish between angle spiral and
Eccentric spiral.
Another limitation of all these prior art disclosures is that while to can determine that the spiral feature of golf,
But the information that can how or why produce these features can not be provided.The present invention tries hard to overcome these limitations of prior art
Property.
Background technology
Golf spiral great importance in golf sports because spiral significantly affect golf ball flight and with
Bounce-back afterwards and rolling.Although around single-rotation axis spiral in general Golf coaching, generally from chop and side spin
Vertically and horizontally component studies spiral.Chop is appeared in the aerial impact of standard all the time, and according to batting mode and
It is required that chop generally has optimal transmitted value.Side spin is also appeared in standard aerial impact sometimes, and with progressively laterally
Deviate trajectory relevant.In this specification, all terms are applied to the golfer for batting from right to left, almost including all right sides
The player of forehand hit and the player of most of left hand batting.In this explanation, spiral discussion is only applicable to iron and rod batting, art
Language ' wood ' bar includes all aluminum medal woods of kick off rod and omnipotent club etc..This specification does not include mainly occurring compared with low speed
Two dimension is pushed out.
When iron type golf club golf, there are two kinds of basic conditions to cause spiral.One of which situation is produced
So-called ' angle spiral ', square stance, the contact point three-dimensional vertical line on face occurs when not parallel with club motion three-dimensional
Such case.When face and angled trunnion axis, because club has loft angle, after all standard golf ball-battings
There is the situation.If face is at an angle of with vertical axis, i.e. also there is such case in face ' opening ' or ' conjunction '.In addition,
When contact point vertical line is just aligned with target direction, but square stance club head in the poor direction with target direction misalignment really
Also there is such case during close to golf.It is properly positioned during orientation is batted and above-mentioned situation, wherein golf equally occurs
Face center is flown away from, and face bends, and such as typically occurs in the case of using kick off rod and other rods, because ball
Pole face curvature can cause vertical line and target direction misalignment.
If ball does eccentric motion in the horizontal or vertical directions after being batted by club, and club head center of gravity is clearly located in
When behind face, generally occurring within causes another situation of spiral, for example, being particularly during with a rod, can cause partially
The heart move, during with other rods, eccentric motion is done with less angle, when using iron, with smaller angle do eccentric motion or
Move without acceptance of persons.This kind of spiral is relevant with the rotation of club head so that the friction between ball surface and rotation club head surface is nibbled
Conjunction causes reverse spiral.The term that less science is commonly used in golf common saying is referred to as " gear effect spiral ", but this specification
Using term " eccentric spiral ".In the case where certain bias spiral is produced with iron, compared with the effect that rod is produced, iron
The higher angular spiral that matches for generally producing is with generally shorter iron shot distance (side spin influences smaller to trajectory) further
Reduce the effect that iron is produced.It is hook-shaped trajectory that eccentric spiral can cause level bias head toe batting, level bias heel
It is oblique trajectory to bat to chamfer the batting high of trajectory, vertical eccentric, vertical eccentric is low bats as awscent trajectory." toe " and " with
Portion " refer to respectively away from the club side near shaft.For these spiral effects are contained in part and produce in club certain
" forgiveness " of degree, a rod and other rod manufacturers are disposed across face in the horizontal and vertical directions respectively
" protrusion " and " fluctuating " folding line.Although eccentric spiral is generally dominant, the folding line facilitates the spiral of certain angle, and promotees
The batting of orientation in the reverse direction in direction caused by Cheng Yu bias spirals.According to golf rule, rod can have the folding line,
Must not there is the folding line in the iron that must have plane.
In the event of angle spiral and eccentric spiral, they can form a single combination spiral, can be according to chop and side
Spiral component observes the combination spiral, although it is actually with depending on the inclined tool of chop and side spin component proportion
With the presence of total combination spiral of spiral axle.During without side spin, the direction of motion of spiral axle and ball in same level, and therewith just
Hand over.Spiral direction of rotation rises for ball leading edge, and trailing edge declines.Although spiral is generally not enough by the 1% of batting kinetic energy, due to
Spiral can make trajectory raise and bend in the case where directly energy is not used, and be acted in the way of rudder sometimes, therefore, rotation
Ball can produce out-of-proportion huge effect to trajectory.Direction with spiral axle and ball produces rising at a right angle.This cause ball to
Left or to right rotation, wherein side spin makes spiral axle be inclined away from horizontal direction.If ball is just in uphill process, it can also be produced
Raw component and drag backward, make ball slow down.Equally, if ball is in during decline, it can cause to resist drag
Forwards components, accelerate ball.When ball reaches ground, golf will generally keep its most of initial spiral energy.
Face center is defined essentially by the vertical line of the face for being projected back to club head center of gravity.Because manufacturer has
When be deliberately disposed at slightly off-center position to realize some specific functions, face center is not necessarily located in
The geometric center of face, for example, if it is considered to player tend to chop, it is moved several millimeters to heel sometimes and is mended
Repay.Face vertical line since center of gravity is also normally positioned at the face geometric center top position of a bit.For standard at a high speed
Batting, square stance, shaft will not produce great effect to vertical axial club movement characteristic.Square stance, it is to trunnion axis
The influence of the movement characteristic of surrounding is also very small, unless shaft is provided with stone tip in club cephalic par.
The content of the invention
The present invention is more specifically limited by the appended system claims and device claim of including this specification.
An aspect of of the present present invention is related to one kind to understand, that is, generally using, and measurement or determination offer one kind can be accurate indirectly

The most useful feedback information related to spiral spiral feature of person often with known case under according to empirically determined special sort
Or the ball average characteristics of type are relevant, rather than have with the concrete property and ambient conditions of ball actually used in tested batting
Close, and this is allowed it is determined that solving many X factors during feature and eliminating the unnecessary measurement of irrelevant variable.Specifically,
The spiral feature of ball is influenceed by the ball material coefficient of resilience and cladding material hardness relevant feature, from spiral feature with making
Actually uninterested mode changes user.For example, spiral feature can be with feelings such as ball temperature, the time for using and structural conditions
There is great change, ball temperature, the length of playing a ball game and structural condition etc. and be referred to as " condition of ball " in condition, user does not know under normal circumstances
These situations of ball.User generally hits the ball of special sort or type in known previously selected temperature to it with the conditions of
The spiral feature for causing is interested.This different shot for also allowing to produce different balls under different ambient conditions enters
The more meaningful comparing of row, to provide more consistent result.
In actual impact, some characteristics of ball can influence spiral characteristic, but can not possibly influence measurement indirectly, all the time
Replace these characteristics of ball advantageous by the related standard feature of the normal play of user.For example, the surface mill of type
Damage or damage can cause this kind of situation.Part of properties may influence indirectly measurement, but, these characteristics be not usually very significantly,
Because indirect measured deviation is caused by the characteristic unrelated with user, therefore, it is, in general, that it is still conducive to using
Person uses standard feature.In order to reduce these effects as far as possible, user should using characteristic with have standard feature it is ball as
Test ball.

Determine angle spiral axle and angle spiral speed
From for symmetry, can be shown that angle spiral axle before batting perpendicular to the club direction of motion and most primiparity for producing
The raw ball direction of motion, such as ball leaves face.In this manual, unless otherwise prescribed, ' direction ' represents that 3D (three-dimensional) is empty
Between in direction.The club direction of motion (synonymous with the club head direction of motion) of generation should be referred to as ' club direction ', generation
The ball direction of motion should be referred to as ' direction of bowl '.Because club direction and direction of bowl are forever uneven in the skilled batting of any standard
OK, their orientation correspondingly determines the orientation of angle spiral axle.Angle spiral axle be do not exist or when being not counted in eccentric spiral ball around
The axle of its spiral.
By relation:Tan (λ)=ω as/ ω ab obtain the side spin of angle of departure spiral and the ratio of chop component, wherein λ
Be in the absence of or angle when being not counted in eccentric spiral between trunnion axis and spiral axle;ω as are angle side spin speed;ω ab are
Angle chop speed.
Due to changeability and uncertain (ball deforms on face when angle spiral is produced), angle spiral speed is actually not
It is suitable to accurate general mathematical treatment.However, drawing following result from empirical test.Under equal conditions, angle spiral essence
Upper and club velocity and face deflection sine linear proportional, with the linear inverse ratio of the moment of inertia of ball.Term ' face side
To angle ' represent square stance face at ball contact point vertical and between 3D vertical lines angle.Similarly, angle spiral substantially with
Mc/ (mb+mc) ratio linear proportional, wherein mb and mc is respectively the quality of ball and club.Similarly, angle spiral substantially with
The different ratio linear proportional of ball speed difference that face elastic characteristic difference is caused.The ratio can also use returning that ball and face are combined
The equivalent proportion for playing coefficient is represented.Angle spiral is also heavily dependent on structure, elasticity and the deformation characteristic of ball, including ball
The variables such as temperature, the length of playing a ball game and condition.The expression mathematically of dependence behind these is complicated, variable and difficulty.In default ring
Under the conditions of border, angle is set to determine to concentrate on the proper range of ball example easily to delete these relations from exercise, as previously described.
The club correlated variables of face quality and club surface elastic is not considered temporarily, for giving giving under environmental condition
Determine ball and club, combination spiral speed is drawn by following:ω a=K.Vc.sin α, wherein, ω a are combination angle spiral speed;K
To give the steady state value of ball and club condition;Vc is the combination club head speed before batting;α is face deflection.Needing
Or it is selected it is any under the conditions of, by the true defining K value of the investigative test of each ball-type.If the club of similar characteristic is used for exploration tried
Test with true defining K value, can also eliminate the demand for determining club relevant variable.Or, it is above-mentioned by the way that the angle spiral value of determination is multiplied by
Appropriate adjustment ratio makes the single value of K can be used for the club of different club head quality or face elastic characteristic.
In the case of adjustment club head quality (but quality is unknown in advance), can be kept according to momentum before batting and after batting
Constant rule club direction of motion before batting is determined by using following kind of relation direct measurement ball or club velocity:
Mc.Vc=mc.Wc.cos (ξ)+mb.Vb.cos (ψ), wherein mc are club head quality;Mb is ball quality;Vc is club before batting
Head speed;Wc is club head speed after batting;Vb is ball speed after batting;ξ is the angle between the front and rear club head direction of batting;
ψ is the angle after club head direction and batting between ball speed before batting.Can be by all arts in direct measurement acquisition relation
Language (except mc and mb).The higher limit of ball weight is limited due to regulator, when all standard balls are quite similar, readily estimated mb
Value.
Club head elastic module is primarily referred to as generally being obtained by sake aluminum medal wood, especially number rod of major part titanium alloy
Other elasticity for obtaining.These other elasticity give all or most of gold of face size depending on the upper limit of regulator
Most there is category rod similar elastic characteristic to seem increasingly may at last.Therefore, elasticity will gradually count the K that experiment determines
Value.
Determine face direction and face deflection
From for symmetry, the 3D vertical lines orientation of face is can be shown that, if contacted with ball first, in club direction
With direction of bowl identical plane.Face vertical line should be referred to as in ' face direction '.
Face angle of vertical should be referred to as ' face deflection ' in the range of 3D reference systems, and can be by including vertical direction
Axle with anticipated orientation easily determines in the range of reference system.If face is in the horizontal plane square, face direction
Angle is identical with common golf term ' dynamic loft angle '.Face deflection can be determined by directly or indirectly measurement, or made
Estimate face deflection with empirically determined method, as described below, its ' experience ' method for being referred to as determining this angle.
According to the loft angle of club, face direction angle value is about the 130%-110% of combined spheres deflection, all
In the case of be worth and reduced with the reduction at face direction and club face oblique angle, in the range of value also change with ball-type.Experiment is aobvious
Show the single mathematic(al) representation of any given ball-type, such as following second order polynomial relation, can be in the direction of bowl angle model for typically encountering
Interior offer rationally accurate face bearing estimate is provided:γ=a. θ 2+b. θ, wherein γ are face deflection;θ is ball side
To angle;A and b is the experience gained coefficient of expression formula.Following relation is applied to a conventional ball type in the case where typically encountering:
γ=(0.027) θ 2+ (0.75) θ.Experiment further shows result only to ball-type medium sensitivity, so, less representativeness
Ball-type data from the sample survey can fully cover all types of similar level of accuracy.Mathematical table can easily be drawn by investigative test
Up to the coefficient data in formula.
It is determined that eccentric spiral
If producing eccentric spiral, off-center hits make club head be rotated around its mass centre, face edge can be made in turn
Ball surface is moved, so as to produce spiral.In the case of consistent unit, the phase being related in the shot and combination rotation
The simple analysis of Guan Li, motion and geometry provide following relation:β .I=Vb.d.mb, and ω o=A. β/π Db, therefore
Conclusion is:ω o=[Vb.d] [A/I] [mb/ π Db], wherein ω o are the eccentric spiral speed that ball is produced;β leaves club for ball
Angular speed of the club head around its mass centre during face;D is from the normal striking point on the ball of face to the eccentric throw of its mass centre;mb
It is ball quality;Ball speed after Vb batting;I is the moment of inertia of the club head around its axle for passing through mass centre, and wherein club revolves around axle
Turn;Db is bulb diameter, and A is the distance of mass centre after face.
In the case, the horizontal and vertical component of eccentric spiral is preferably individually calculated, due to club head inertia values
The rotation of opposing connection vertically and horizontally axle is entirely different, generally only available by these axles or easily calculate.Relation is as follows, wherein under
Mark h and v represents horizontal and vertical respectively:ω oh=[Vb.dh] [A/Ih] [mb/ π Db] and ω ov=[Vb.dv] [A/Iv]
[mb/ π Db], wherein ω oh are the combined horizontal component of ball bias spiral;Dh is the vertical line striking point on the ball of face in its quality
The horizontal component of the eccentric throw of the heart, i.e. the horizontal displacement of power;Ih is inertia of the club head around the trunnion axis by its mass centre
Square;ω ov are the combined horizontal component of ball bias spiral;Dv is the vertical line striking point on the ball of face to its mass centre's eccentric throw
Horizontal component, i.e. the horizontal displacement of power;Iv is the moment of inertia of the club head around the trunnion axis by its mass centre.
All entry value are related to ball in [mb/ π Db] and can use at any time.Most balls meet presently relevant set by regulatory authorities
Limitation, the minimum 4.267cm of diameter, quality is 45.93g to the maximum.
The value of [A/Ih] and [A/Iv] is that club is peculiar, has been announced and suitable for many clubs, especially level value.Or
Person, can precalculate value by well-known standard and the method for determining.Simultaneously it should be noted that the A/I ratios of most of clubs are total
It is quite stable, is divided into and is typically designed classification, is included in manufacture in the 460cc volumetric constraints being currently set by regulator agencies
A most of modern rod club.This mode allows to use A/I standard default values, unless known ball is marked beyond these
Quasi- value, therefore more correlations can be replaced.It should also be noted that regulator agencies have been currently set club head horizontal inertial square maximum
It is 5900g cm2 to be worth, but seldom club can be really achieved the value (if there is).
Relation between spiral feature
The component of combination angle spiral and eccentric spiral determines the total of spiral speed and spiral axle in identical reference system
Component.The combination can be readily achieved by the mathematical skill of various abundant checkings.Term ' total ' herein should represent that angle is revolved
The combination or the combination of these components of ball and eccentric spiral.Term ' total spiral ', ' total side spin ' and ' total chop ' is also distinguished
Synonymous with term ' spiral ', ' side spin ' and ' chop ', these terms and angle spiral or biasing spiral are without clearly contacting.
Mathematically related spiral velocity component is as follows:ω a2=ω as2+ ω ab2 and ω o2=ω os2+ ω ob2, its
Middle ω a are angle spiral speed;ω as are angle side spin speed;ω ab are angle chop speed;ω o are eccentric spiral speed;ω
Os is eccentric side spin speed;ω ob are eccentric chop speed.

Person's standing surface or mat.This figure also illustrates the golf being in place before being hit by club, while also show virtual straight
Line and arrow, from left to right represent the estimated ball direction of motion.The figure illustrates number rod batting arrangement of standard, wherein standing surface
Placed away from ball with mirror apparatus.For shorter club, placed in the way of closer to ball, can be put in nearest position
Ball.' estimated ' direction is often referred to hit a ball and his or her batting can be directed at enveloping field, striking surface or standing by user
The target direction of the parallel edges in face.
With reference to Fig. 4, the light beam of mark has following functions and arrangement.Towards the F1 and F2 of collimated light beam and dorsad parallel
The B1 and B2 of light beam are used to detect that club is moved.Light beam F3 and B3 are used to detect the motion of ball resting position, hitting time and club.
Towards collimated light beam F4 and F5 and dorsad the B4 and B5 of collimated light beam be used for detect ball move.By all light beams be set to
Estimated direction is in 65 °.It is several that associated beam such as F1 and B1 are represented with form ' F1-B1 ' sometimes for succinct and clear.Light beam
The joining of F1-B1, F2-B2, F3-B3, F4-B4 and F5-B5 is respectively positioned on the straight line by the estimated direction of the centre of sphere.F1-B1
50mm and 20mm is respectively with the distance between the joining of F2-B2 and the joining of F2-B2 and F3-B3.The joining of F2-B2
It is 38mm with the distance between the centre of sphere.The centre of sphere is at least 41mm with the distance of F4-B4 joinings.The joining of F4-B4 and F5-B5
The distance between be 30mm.
Fig. 5 and Fig. 6 are similar with Fig. 3 and Fig. 4 respectively, but beam arrangement includes two kinds of any changes.These arbitrarily change
In one include other light beams to F0-B0, F0-B0, F1-B1 and F2-B2 detection club can only be moved by light beam, and by light
Beam detects ball resting position and hitting time to F3-B3.Other any changes include detecting other balls of light beam to F6-B6.
Arrangement shown in Fig. 3 and Fig. 4 with less part and low cost, complexity reduction and size reduce it is relatively excellent
Gesture, meets in performance and can be used when operation is required.In the arrangement shown in Fig. 5 and Fig. 6, depressed trajectory batting, such as with rod and length
Iron shot occurs simultaneously, and F4-B4 and F6-B6 are measured by light beam, and high trajectory batting then by light beam to F4-B4 and
F5-B5 is measured.Increase light beam to F6-B6 to provide farther distance, by this apart from the flight path of measurable ball increasing survey
The amount degree of accuracy.Light beam can not be moved to the position farther out to F5-B5 because high trajectory batting will to rise to this high apart from 110mm
The extreme higher position of light beam.In the arrangement shown in Fig. 5 and Fig. 6, single group light beam no longer detects initial conditions and the club motion of ball.
In the case of several, it is believed that it is desirable, including situations below that this function is separated.It is considered that the segment beam being blocked by the ball is damaged
Losing can be to detecting that the reliability and accuracy of club have a negative impact.Think the detection that the accurate static position for being adapted to ball is detected
Device is unsuitable for the accurate of club and detects at high speed.
Other beam arrangements and change in size can be used.Several group directional lights symmetrical with the score of ball need not be used
Beam, but this arrangement can simplify the calculating of system and understand and optimize various variables, and partly cause is that analogue is suitable to target
The both sides of line.There is normalization component using consistent beam angle and convenient more close component is arranged.Selection
Beam angle reduces the optimum balance of plant bulk mainly as horizontal detection sensitivity and as far as possible.Selection light beam and beam heights
The distance between mainly as detection sensitivity, catch striking limits on the ball and as far as possible reduce plant bulk optimum balance.
Although example system includes the six club measuring beams set with two different angles, club measuring beam
Minimum requirements is at least three or four light beams and at least two different angles.It is preferable, however, that four light beams are realizing different angles
Balance between degree group simultaneously obtains high accuracy.When club is shifted to and moves into hitting region, it is special that a large amount of light beams provide other
Point or change change information.These light beams can also sharing function, such as measurement of place kick and hitting time.Equally, although showing
Example system includes the four or six ball measuring beams set with two different angles, but the minimum requirements of ball measuring beam is two
Light beam and must again with different angles set.Because the symmetry and measuring characteristic or variable of ball are reduced, minimum beam number
The amount quantity required less than club motion.But, as discussed in exemplary arrangement description, must be realized with more ball measuring beams
The degree of accuracy higher.
Device includes striking surface and the ball of ground, ground support or toe is placed directly in before batting.Striking surface includes resistance to
With artificial turf or polymer pad.By the way of, ball is positioned over flexibly or on Collapsible rack with similar to training field
It is required that height.Standing surface or mat are used for balancing the height of the height with striking surface of user standing place.Although not having in figure
It has been shown that, the device also includes User's Interface and programming electronic processors, and the processor is operable to change the signal of light beam
Into club and the movement characteristic of ball, described elsewhere method in this specification is conformed generally to.
Referring now to Fig. 7, every light beam described in Fig. 3 to Fig. 6 includes arrangement form shown in Fig. 3.It is made up of laser diode
Transmitter dissipated strongly with vertical direction, while the mode of lateral divergence sends light beam.(referred to as laser is saturating by lens for light beam
Mirror), light beam is modified as more flat shape by it, while from edge, most weak to be modified as center most weak by intensity distribution.Because light beam
The optical transmission loss at edge is higher, can change intensity distribution to show most uniform final distribution in photodiode array.
Beam splitter intercepts flat top beam, hop light beam, is modified as putting down through the vertical collimating lens for extending, by light beam
Row collimation form.Unless stopped by club or ball or partly stopped by it, collimated light beam passes through striking surface by this form, while
Reflected back along outer pathway by reflective mirror.The reflected beams return to collimation lens, and convergence form is converted into from parallel collimated form,
This is completely different with the conversion of outer pathway.Returning beam meets with beam splitter, is partly reflected back, and forms the light electric-examination of vertically-guided
Device dot matrix image is surveyed, can be arbitrarily inverted as shown in the figure.Beam splitter is rotated around vertical axis, from right-angle steering outgoing and the light beam for returning
Path, positions detector and slightly offsets collimation lens and outgoing beam path.Therefore, by any thing of main collimated light beam
Body will on the detector array form proportional contour images.Component is with main collimated light beam thickness 1mm's and height 110mm
Mode is arranged.
The collimation lens being made up of the Fresnel facet of longitudinal array performs two tasks:By penetrating for laser and laser lens
The outgoing through striking surface that line is divided into parallel collimated form operates light beam;And Returning beam is focused on into convergence ray, most
The image of photoelectric detector dot matrix is generated eventually.Collimation lens is produced with injection molding of polymers, and its cross section is as shown in Figure 8.Each face
Vertical height about 1mm, width about 2mm.As viewed from horizontal profile, these faces are substantially flat, but are song as viewed from vertical section
Line.Each face is set to be adapted to angle, the segment beam of the direction of collimation of requirement is refracted through.Molding is with a series of of beam angle
Face produces, and molding is accurately fitted within shell easily, and main body and locating flange are towards shell main shaft.Molding also with it is each
Total molding screen is provided with the relative surface in face.These screens are made up of angled face, and these faces extend to molding optical
Partial overall height and offset operation light beam;Any width of distance is increased and is set with the beam thickness for selecting between screen, described
It is 1mm in example.Therefore, collimated light beam is adjusted to the light beams wide of 1mm in outer pathway, is adjusted to 1mm during return again.This has
Help eliminate the dispersion that other light communication effects laterally occurred along each side diffraction of beam path and reflective mirror are produced.
Reflective mirror also includes injection molding of polymers, but can reflect all preceding to light beam with first time injection in the case,
All backward light beams are reflected using second injection simultaneously.Generally, mirror surface includes reflecting light back into the intensive of source
A series of optics corner cubes.Corner cube has three reflectings surface mutually in 90 °.From in terms of signal viewpoint, speculum it is total
Body direction is quite not added with differentiating, although it can influence intensity level and return to collision light with the at a relatively high degree of accuracy along same paths
Beam.
Photoelectric detector may include various types of devices, including photodiode, charge-coupled image sensor (CCD) and complementation
Metal-oxide semiconductor (MOS) (CMOS) linear array, respectively the perpendicular alignmnet pixel including single arrangement.Detector array type
Selection generally include vertically and horizontally to go up the compromise of cost and picture resolution.
Reflective mirror causes being greatly reduced for beam intensity, this can by using back paint reduce or minimize light beam with it is reflective
The angle in device face.There is potential reflection efficiency higher, some common cheap coating such as aluminium paint other side without reflectorizing of paint mirror
It is more sensitive to angle, but the back side is easily by dirt or condensate pollution.It is silver-plated more effective but more expensive.
Because beam intensity reduction makes height output laser power necessitate caused by retroeflection, this is likely to require and takes spy again
Different measure ensures laser intensity level in the eye safety limit.In the exemplary embodiment using one of following special measure or
Its combination.The laser beam of intermittent power supply can be used, when opening, intensity level when its eye safety intensity level is powered than its continuation
It is higher.In the cost laser diode of batch production, there is wavelength selective.Advantageously, the eye safety level of long wavelength
It is higher.For example, when intensity level is about the intensity level of 785nm much larger than visible wavelength, near-infrared wavelength can be used safely about
The diode of 980nm.The laser intensity in exposed external beam can also be increased by using uneven beam splitter.In example system
In system, return light and the ratio of photodiode or sensor that beam splitter reflects are more than the ratio of the emergent light passed back towards laser
Example.When the intensity of photodiode is governing factor, it allows the intensity of exposed external beam to be less than because using uniform point
Beam mirror and the intensity that occurs, but need bigger power output laser.When the intensity of photodiode is not governing factor, generally
In the case of preferably with uniform beam splitter, the light of its projection and reflection similar quantity.
The instant shut-in that guide beam realizes light beam can be provided by first group of upstream of club light beam.Work as guide beam
When being upset by club, it is being enough to catch open laser beam in the short time of club and ball motion.Guide beam may include work(
Rate is enough to low to two LED beams or laser spots light beam that allow continuous safety operation.In exemplary arrangement, guide beam with
Preceding two club light beams are parallel or nearly parallel arrangement, and are returned by reflective mirror.Put the approximate horizontal equivalent to club banding of light beam
The centre position of light beam.Single light sensors go out return signal.Guide beam is not passed through Fresnel Lenses or beam splitter.Can
Light beam is directed to using nearly parallel guide beam point to reflective mirror so as to avoid using size to be wanted more than club and ball measuring beam
Seek the reflective mirror of size.Nearly parallel guide beam is set to the upstream of club light beam in club measurement zone.Such guide beam
As shown in the underscore in Fig. 3 and Fig. 5.In laser spots light beam using the type equipped with built-in photodiode feedback controller
When, this photodiode can also be used to provide echo-signal.LED or laser spots light beam can be arranged on above case nose, with phenanthrene
The array of alunite ear lens is substantially consistent.Because Fresnel lens is placed on position away from shell edge by the first two club, therefore
It will increase the requirement length of sleeve pipe.The use of guide beam further provides for the following two kinds help.It reduces continuous operation
The unnecessary heat that club and ball measuring beam are produced, this may cause light distortion in the unnecessary thermal expansion of component and shell
Cross-ventilation.It also reduces the usage amount of power, when device is battery-powered, its is most important.
As described above, laser diode emitters are selected according to the standard including following content:Diverging feature, cost and
The light beam that the overall safety of sealing device housing exterior is provided and the peak power for meeting safety notice and regulation.Can pass through
The characteristics of matching laser mirror, increases laser intensity so as to the light for producing the aperture at vertically and horizontally divergence and collimation lens to match
Beam.
Assembling is manufactured as follows to be carried out Electronic Calibration to each device to optimize the degree of accuracy of beam detection.For example, can be
In the case of careful control by by the precision target of suitable shape through assembling device the theoretical right value of light beam and record with
The difference normalized between the actual pixels reading of detector is calibrated.Then the data related to these differences are supplied to dress
The software in processor is put, so as to correct the detection reading of each pixel according to calibration test result.This calibration process will make accurate
The general assembly of ball-beam system is down in true property requirement, and increased the overall accuracy of the beam system of complete form.
Alternatively, the present apparatus is also provided with allowing the instrument of user's calibrating installation, if for example, device is suffering damage
Or lose accuracy after extension use, then can use above-mentioned instrument.For example, school can be carried out by providing software facility to device
It is accurate.When user activates, software facility is allowed by impacting along the target direction of left and right directions with high speed and low parabola
By golf (batting of appearance of such as being batted in conventional rod) calibration pixel value of light beam.Can be used be conducive to puncturing it is all
The ball seat position of light beam.Can be with correct pixel value in prediction theory and can be by its actual specification pixel reading with detector
When comparing, the known symmetric shape of golf provides one under the cooperation of rod batting generally vertically and at the uniform velocity
The accurate target known, so as to be calibrated automatically by de-vice processor.Because calibration is only based on high-speed straight-line ball, therefore
The ball that there is no need to be treated at accurate orientation or the elevation angle impact carries out calibration test.
Measurement ball velocity
The conventional method for measuring ball velocity is true through reference position during each light beam thereon by trackball first
The fixed ball trajectory through light beam.Then ball velocity is calculated by analyzing information.In free flight, the three dimensional symmetry of ball
Allow the center reference location of ball.The reference point when first stage of this method includes determining ball by each beam center
Highly, and this action time marking.In this stage, the lateral position of reference point is unknown in light beam.In second stage, by
Will be with these matching criterias, therefore utilization these fixed reference points height, times in only one trajectory and a kind of speed
Mark, the known geometry of light beam and the understanding to the substantially linear uniform motion of golf determine ball in three dimensions
The rectilinear direction and speed of flight.Determine calculated value with electronic processors.In the phase III, by estimating and ball free flight
Start the starting point that corresponding time marking determines ball velocity.
Various image processing techniques can be used to determine the centre-height of ball and with corresponding when center is through each light beam
Time marking, should now describe one of which technology.At each light beam, as ball passes through each light beam, detector array is entered with high speed
A series of scannings of row, respectively scan the generation measured value at each pixel of detector array.If light beam is covered, in batting
Before, it is each pixel specification scan data by using the calibration value determined between the laser diode closed and open.By normal
Rule method smooths authority data.Image definition is improved by increasing the pixel quantity in scan frequency and photodiode,
Vice versa.Selecting the major criterion of these variables includes composition cost.In this example system, it has been found that in about 120kHz
Frequency down-sweep 16 pixel photodiodes it is satisfactory, its available relatively low unit cost (including handling implement
Cost) production.
Each scanning generates one with ball in the related scans time image corresponding to the covering mode of light beam.Can make
Ball center is determined by scan data with various image processing methods.For example, processor can be right by best-fit Gaussian curve etc.
Curve is claimed to be adapted with the pixel value of each scanning or the scan values of each pixel, this will set specific by along vertical axis or trunnion axis
Which more high factor is the resolution ratio of device determine.The center of these curves is found by the differential method, makes best-fit Gauss bent
The final symmetrical curve such as line adapts to these centers again.Find the center of final curves again by the differential method, center of curve with
Ball center's reference point through beam thickness midpoint is corresponding.Record each light beam time marking corresponding with ball center reference point
And vertical height.This technology can make all values collected in the scanning of all detection balls be conducive to finally determining ball center.
Fraction top dome Yin Taigao and when cannot be caught by light beam, suitably adjusted.In correct application, the symmetry of e measurement technology
For vertical or tilt through the ball of light beam and provides same accurate result.
Ball speed is estimated by the time marking for evaluating the starting point on the separate point of ball and face and free flight
Spend the starting point of vector.Time is estimated by the initial hitting time that the time to contact estimation value of ball and face is added to measurement
Mark.According to time marking corresponding with the first time significant changes of light beam F3 to B3 picture element signals determine batting it is initial when
Between, wherein light beam F3 to B3 is covered in frame ball and resting position by ball.The time of contact of ball and face is close to all normal height
The 0.45ms of Er Fu batting, is slightly different its loft angle and speed because of ball-type, condition and club head.
Measure the initial position and hitting time of ball
In an exemplary embodiment of the present invention, golf is arranged on adjustable shelf or ball is substantially placed on relative to light beam
Perfect symmetry position ball seat on.Then the initial rest position of ball, the one of light beam F3 to B3 are measured using light beam F3 to B3
Part is covered by the ball of ground or frame ball position.The pixel that calibration present processor occurs with each possible resting position determined in ball
Inaccessible unique pattern.Based on some reasons, this method may be better than using the fixed precision frame relative to light beam.One of them
Reason is ball seat or fixed mount setting is flexible or the foldable batting such that it is able to bear club, as using durable rubber in training field
Glueballs seat type and as generally occurring, predictable ball seat or fixed mount may because commonly using and there is part deformation or mill
Damage.Another reason is to rigidly fix frame to send problematic shock wave to device, or is caused in square stance portable
Striking surface or device are moved.
Light beam F3 to B3 is additionally operable to measure accurate hitting time, in the club just reached by upstream club beam detection
Afterwards, batting will simultaneously occur with the change first of the output signal of these light beams.The conventional letter measured using pixel value gray scale
Number processing mode is used to insert the precise time of initial motion, so as to provide more accurate than the scan frequency of detector array
Resolution ratio.
Light beam F3 to B3 is additionally operable to inform whether user's ball is correctly installed or be placed on ball seat.For example, due to being damaged ball
The misaligned or match striking surface of seat such as misplaces at the reason, if ball is located at outside the feasible detection range of light beam, can be by proper
When visible or audible mode remind user.
Determine club velocity, club direction, club type and face deflection
When being passed through to club head by wherein one club light beam scanning, optimal direct result is seen in beam tilts
See the bidimensional sketch figure picture of club head.There is various detections and measurement difficulty, especially club head not in such club head image
The difficulty that the orientation range that regular curve shape and Qi Ke are aimed is caused.Although the surface of rod is slightly put down, iron surface is complete
It is flat, but it is clearly distinguishable from club head body.Because the curved profile of face and main body is different, therefore can not be
Face direction and face deflection are detected in the bidimensional oblique view of profile outline easily.It should be understood that there is Fig. 9 (a) and Fig. 9
Standard ball bar shown in (b), even if club head is located at the clear view in intermediate orientation and heel forward position and toe forward position.Term " in
Between orientation " refer to and navigated to equal to dynamic loft angle club with quiet loft angle, the roll angle of club for zero degree, i.e. face and
Face leading line horizontal location.More it is difficult to determine whether face deflection view changes away from middle direction.
In the case of the toe forward position of iron shown in Figure 10 (a), because the flexibility of club head contour is smaller than the flexibility of rod profile,
Therefore face deflection can to a certain extent be distinguished.But, appearing angle will change, club with vertical dynamic loft angle
The roll angle of head changes in actually batting, and face deflection is still difficult to determine.In addition, some for iron club head
Positioning, for the Long Irons especially with low loft angle, hosel can cover most of forward position.In iron shown in Figure 10 (b)
Toe forward position in the case of, because the rear portion of club head and the bottom of hosel are completely covered by visible edge, therefore can not be complete
Distinguish face deflection.Similarly, attempting permanent datum as the figure that can directly compare with known club head feature
Still encountered difficulties when picture or measurement.
If accurately to measure or determine required motion feature, these need to be overcome difficult.It is tired instant invention overcomes these
Difficulty, on the detailed example how to overcome difficulties as shown below.For ease of description, this method is summarized in the way of step.Step
The rapid group for being not necessarily intended in chronological order or showing occurs.
Step 1:Club head is scanned at each light beam in six club light beams.
Step 2:Scan data is processed as predetermined related data, is for convenience's sake referred to as related data
" key parameter ".
Step 3:Determine the reference point relative to club head using some of them key parameter.Reference point is made by light beam
Tracked for club head is in progress, there is provided club head direction and rate curve value.
Step 4:Direction and velocity amplitude are used for specification key parameter.
Step 5:Previously determined ball movement characteristic and normalization and non-normalized club key parameter are used to determine
Club type and face deflection.
Step 6:The data that previous steps are obtained and the knowledge on time marking and light beam geometries are used in ball
Head improves and determines the value in club direction through light beam and in the moment batted.
Step 7:Using in memory or other faces determined specific to the club type and face direction that determine
Position of the heart relative to some key parameters.
Step 8:It is true by previously determined ball information and previous steps by relatively early disclosed method in this specification
Fixed club information determines spiral feature.
These steps are now more fully described, arranged shown in Fig. 3 and Fig. 4 with being understood.
Step 1:Club head is scanned at each light beam in club light beam F1, B1, F2, B2, F3 and B3.With similar to previous
According to routine preliminary treatment signal, to measure direction of bowl, it includes normalizing and smooths described mode.
Step 2:Scan data is further processed into predetermined key parameter.
In first variant of this step, key parameter includes position and the angle of shaft axle, various relative from other
Selected in the measurement of simple definition, the image length and height of ' A ' and ' B ' are such as respectively indicated as in Figure 11 (a) to 12 (b)
Degree, and the height for being shown as guiding point on the forward position of ' C '.If using rod and toe light beam iron, key parameter is also wrapped
Intersecting for hosel and club head contour is included, it is shown as ' D ' and ' E ' in Figure 11 (a), 11 (b) and 12 (a).If using with
Portion's light beam iron, key parameter comprises additionally in the Relative vertical and horizontal level of the minimum point of bending section between the knife back and hosel,
It is shown as ' G ' in Figure 12 (b).
In second variant, key parameter includes position and the angle of shaft axle.It also includes club head and hosel institute
Have and obtained by processing scanning with part outline profile, profile.Various two grades of measurements are determined according to profile, including is become with first
Described in formula be similar to measured value, be optimally adapted to the forward position of toe light beam rod and iron, be suitable to the forward position of heel light beam rod with
And it is suitable to the angle of the line at heel light beam iron top knife back edge.
As shown in Figure 12 (a), the root side profile of root light beam iron image does not have visible highest, minimum or benchmark
Point.Shaft axle extended line is considered as terminal or datum mark with the intersection point of club lower profile.The intersection point is advantageously located at club head and puts down
Face root near side edges.
Shaft shaft angle degree is an especially important measured value, there is two reasons.First reason is that it can be carried out accurately
Degree measurement higher.This is because shaft axle includes a straight line limited by shaft edge and hosel edge, and shaft edge
It is equal to this air line distance with hosel edge.Shaft axle is also usually closer to vertically, and can pass through during by continuous scanning
Greater number of detector pixel.These factors make measurement have high accuracy.Second important reason of the parameter be, shaft
The face deflection of shaft angle degree and club, vertical dynamic loft angle, roll angle and ball parallactic angle degree close to or it is directly related.Peace
