Via measuring unit, measurement mechanism 2 is measured the distortion (step S04) of golf clubs based on the positional information of obtaining in step S03.Particularly, measuring unit can be measured at least one party in the motion of head 6 and the bending of bar portion 5.The motion of the position measurement head 6 with respect to camera head 4 that in addition, measuring unit can be based on head 6 and the bending of bar portion 5.In this case, as the position of head 6, measuring unit is measured in 10Shang position, the perspective plane of camera head 4.In addition, measuring unit can be determined head 6 in 10Shang position, perspective plane over time, and measure swing during the change of the motion of head 6 and the bending state of bar portion 5.Below with reference to Fig. 3 and Fig. 4, illustrate in greater detail above-mentioned steps S03 and S04 by the perspective plane 10 of explanation camera head 4.
Fig. 3 shows the relation between head 6 and the bar portion 5 of the golf clubs 3 in virtual projection face 10 and the Fig. 1 of the camera head 4 in Fig. 1.Perspective plane 10 is planes vertical with the optical axis of camera head 4.Camera head 4 is installed to bar portion 5 via installation component 11, and the part of the installation camera head 4 of bar portion 5 and head 6 and bar portion 5 compare roughly without bending or only have a little bending near the part of head 6.In the time that the optical axis of camera head 4 is parallel with bar axle, vertical with perspective plane 10 in the bar axle of the bar portion 5 without under case of bending.
During bar portion 5 is swinging, produce bending and while producing the state of the 5a of bar portion shown in broken lines and 5b, bar axle and perspective plane 10 out of plumb.The position coordinates on perspective plane 10 of mark M1 to M3 on head 6 is represented by the location of pixels corresponding with the coordinate figure of the X-axis of describing along the lower left of Fig. 3 and Y-axis.Z axis is the axle parallel with the optical axis of camera head 4.Note, for the sake of clarity, the bending diagram of the 5a of bar portion and 5b is exaggerated.The actual bending occurring is often less than the bending in Fig. 3.
Fig. 4 is the figure that the example of the golf clubs image of catching during swinging by the camera head 4 in Fig. 1 is shown.Bar portion 5 in Fig. 4 and the position of head 6 are the position while being about to clash into, wherein clash into the time point that impacts golf 9 for head 6.Be installed to the upper surface of head 6 as the mark M1 to M3 of identifier.At least one identifier is just enough, certainly, three marks as shown in the figure also can be set, or dissimilar multiple marks are set.In Fig. 4, the mark M4 to M6 being shown in broken lines is corresponding with the position of the beginning tense marker M1 to M3 that swings respectively.In above-mentioned steps S03, the location information acquiring unit of measurement mechanism 2 makes initial point (0,0) be positioned at the positional information of obtaining mark M1 to M3 in the situation as the lower left of the XY plane on perspective plane as pixel coordinate.The positional information on perspective plane 10 of mark M1 to M3 is the relative position of head 6 with respect to camera head 4.
In above-mentioned steps S04, the measuring unit of measurement mechanism 2 can be measured the bending of the bar portion 5 of reflecting in the relative position of head 6 with respect to camera head 4.In addition, use bar portion 5 that the golf clubs 3 of the mark of any amount has been installed, can implement same measurement with amount of bow or the curve form of measuring stick portion 5 even in more detail.
About the motion of head 6, the rotation behavior that measuring unit is can be for example corresponding with the facial direction (face orientation) of head 6 while starting of swinging by calculating, the angle of linkage flag M4 and the straight line (hereinafter referred to as M4-M5 line) of M5 and straight line (hereinafter referred to as the M1-M2 line) formation of connection M1 and M2 is measured head 6.Adopt in this way the rotation behavior that can measure head 6 according to the relative angle with respect to the facial direction of head 6 in the time swinging beginning of each time point head 6 during swinging.In addition, use predetermined model (model), the torsion of bar portion is calculated in rotation behavior that can also be from the head.
Illustrate in greater detail above-mentioned steps S04 below with reference to Fig. 5 to Fig. 8.As shown in Figure 5, the positional information on perspective plane 10 that the measuring unit of measurement mechanism 2 can be determined the mark M1 to M3 obtaining by location information acquiring unit over time.The position that Fig. 5 shows mark M1 to M3 in the X-direction on the perspective plane 10 of camera head 4 over time.Trunnion axis represents the time (ms), and vertical axes represents the position (pixel) in the X-direction on the perspective plane 10 that is respectively marked at camera head.The point that time (ms) is 0 is the shock moment of head 6 while impacting golf 9.In Fig. 5, be clear that, the X-direction position on perspective plane of the mark M1 to M3 on head 6 is tending towards moving similarly towards clashing into about the moment.In order to illustrate in greater detail this trend, first mark M1 to M3 on head 6 moves left along the X axis on perspective plane 10 at the rear a moment starting that swings, move right lentamente along the X-axis on perspective plane 10 subsequently, again move left along the X axis on perspective plane 10 at the eve clashing into, clash into the moment until arrive.
Fig. 6 shows the variation of the position of mark M1 to M3 in the Y direction on the perspective plane of camera head 4 along with the time.Trunnion axis represents the time (ms), and vertical axes represents the position (pixel) in the Y direction on the perspective plane 10 that is respectively marked at camera head.Identical with Fig. 5, the point that the time (ms) is 0 is the shock moment of head 6 while impacting golf 9.In Fig. 6, be clear that, the Y direction position on perspective plane of the mark M1 to M3 on head 6 is tending towards moving similarly up and down towards clashing into the moment.In order to illustrate in greater detail this trend, first the mark M1 to M3 on head 6 rear one is engraved in the Y direction on perspective plane 10 and teeters what swing and start, then in Y-axis positive direction, moves sharp.Then, mark M1 to M3 little by little drops to certain a bit, then declines sharp towards rum point.
As shown in Figure 5 and Figure 6, according to present embodiment, can measure the distortion of the golf clubs 3 reflecting in the motion of head 6.In addition,, according to present embodiment, as shown in Figure 7, can obtain the information of the track on perspective plane 10 of the mark M1 on head 6 during swinging.Rhombus in the chart of Fig. 7 represents rum point.The track on the perspective plane 10 of camera head 4 of mark M1 represents the degree that head 6 is shifted with respect to camera head 4.In the distortion of golf clubs 3, contribute maximum factor to be considered to the bending of bar portion 5 to the relative displacement with respect to camera head 4 of head 6.Therefore, the track of the mark M1 based on as shown in Figure 7, can measure the bending of bar portion 5 while swinging.
In addition, as shown in Figure 8, can measure the rotation behavior of head.This rotation behavior comprises the rotation in direction (toe down direction) (that is, head 6 is away from the direction of bar axle) down of tiptoe for example, and impacts the rotation in direction take bar portion as axle.In Fig. 8, vertical axes represents relative angle, and trunnion axis represents the time (ms).During relative angle is illustrated in and swings, M1-M2 line and M1-M3 line be with respect to the angle of M4-M5 line and M4-M6 line, corresponding with M1-M2 line and M4-M6 line is corresponding with M1-M3 line at the M4-M5 line that swings while starting.On the occasion of representing to impact the rotational angle in direction, negative value represents the rotational angle on rightabout.The M1-M2 line that solid line represents head 6 is the variation along with the time with respect to the angle of M4-M5 line.Dotted line represents the variation along with the time with respect to the angle of M4-M6 line of M1-M3 line.According to Fig. 8, be clear that, at the rear a moment swinging, facial face (face surface) is because inertia shows turn angle, but along with the facial face rotating in positive direction, towards rum point, the rotational angle of facial face to be become gradually negative subsequently.
In Fig. 8, the variation of solid line is larger than the variation of dotted line.This is considered to, and because of head 6 during swinging, at so-called tiptoe, direction (that is, head 6 is away from the direction of bar axle) is upper mobile down, and bar portion 5 produces bending.By being further analyzed together with the measurement result of these data and the bending of bar as above portion, think and can resolve the correlation between the bending of bar portion and head movement.
Adopt in this way, according to the method for present embodiment, can easily measure the motion of head 6 during golfer 8 swings, and not need to measure with multiple camera heads the distortion of golf clubs.Note, in Fig. 5, Fig. 6 and Fig. 8, the data of the head movement during swinging and the bending of bar portion be depicted as through time data (temporal data), and these data not only can obtain into through time data.For example, certainly can calculate these data of interested random time point, such as these data of clashing into the moment.Displacement the state that in this case, the distortion of golf clubs 3 can be defined as not being out of shape completely from golf clubs 3.
Then, with reference to figure 9 and Figure 10 explanation, the measuring system for present embodiment and measuring method are applied to multiple testees' result.With Fig. 7 similarly, the track on perspective plane 10 of the mark M1 during the measurement result in Fig. 9 A to Fig. 9 C shows and swings on head 6.With Fig. 8 similarly, the measurement result in Figure 10 A to Figure 10 C shows the variation along with the time with respect to the relative angle of the initial position of head 6 of head 6 during swinging.In the drawings, the stage swinging is divided into Back swing (solid line), down swing (dotted line) and take advantage of a situation with bar (follow through) (dotted line).Can be by for example setting camera head except camera head 4 to take whole swinging process of the golfer 8 or to distinguish by gyro sensor is set in golf clubs 3 stage swinging.Thereby the stage swinging is distinguished and allows the dissimilar measurement result swinging to carry out the comparative evaluation by the stage.
As high-visible from Fig. 9 A to Fig. 9 C and Figure 10 A to Figure 10 C, each testee's measurement result is mutually different.By compare and measure result and the classification to measurement result after determining characteristic to be compared or waiting to be used as the feature of index, thereby think and can select to be suitable for each testee's golf clubs and think and can support exploitation.
