Hereinafter, the initial trajectory measuring device 40, the swing trajectory measuring device 60, and the head trajectory measuring device 70, which are the golf swing measuring device 12, will be described.
The initial trajectory measuring device 40 can calculate the head speed, the initial velocity of the golf ball, the launch angle (left and right and up and down), and the spin amount (back spin and side spin). The swing trajectory measuring device 60 can calculate a head speed history, a grip speed history, a head trajectory (left and right and up and down), a dynamic loft angle, a dynamic lie angle, and a face angle. The head trajectory measuring device 70 can calculate a head speed, a golf club head trajectory (up and down and left and right), a dynamic loft angle, a dynamic lie angle, a loft angle, and a hitting point position of a golf ball.

  FIG. 6 is a block diagram showing an outline of the initial trajectory measuring apparatus, and FIG. 7 is a block diagram of the initial trajectory measuring apparatus.

The initial trajectory measuring device 40 includes an image capturing device 45 and an initial trajectory calculating device 47.
The image pickup device 45 is reflected by one of the two mirrors 41 and 42 that reflect the image of the golf ball 43 immediately after launch and the image of the golf ball 43 that is reflected by the two mirrors 41 and 42. The half mirror 44 that reflects the image and transmits the image reflected from the other mirror, and the image of the golf ball 43 that has passed through the half mirror 44 and the image of the golf ball that has been reflected by the half mirror 44 are captured together. A high-resolution CCD camera 46 and a control means 49 for controlling the timing of imaging by the camera, etc., picks up a planar image 50 of a golf ball image immediately after launch, and uses the planar image 50 as data for an initial trajectory calculation device. Send to 47.

The mirrors 41 and 42 are disposed at different positions so that the trajectory of the golf ball 43 immediately after being launched can be captured, and project images of the golf ball 43 viewed from two different directions onto the half mirror 44.
When a plane equidistant from the arrangement positions of the mirrors 41 and 42 is set as the target plane 48, the half mirror 44 is arranged so that a boundary surface between the target plane 48 and the half mirror 44 is on the same plane.
By doing so, the inclination angles of the reflecting surfaces of the mirrors 41 and 42 with respect to the half mirror 44 located on the symmetry plane 48 are different from each other in the positive and negative signs and are equal in absolute value (the angle + α ° in FIG. -Α °).

By arranging the half mirror 44 and the mirrors 41 and 42 in this way, the path lengths of the golf ball images reflected by the respective mirrors 41 and 42 and projected onto the half mirror 44 are substantially equal. The path length to the CCD camera 46 is also substantially equal. Accordingly, it is possible to prevent one of the two different golf ball images from being out of focus.
Further, by finely adjusting the positions of the mirrors 41 and 42, the projection angles of the images of the two golf balls projected onto the half mirror 44 can be made to substantially coincide with each other, and the images of the golf balls can be prevented from overlapping each other. Two images can be taken by the CCD camera 46.

The CCD camera 46 is controlled by the control means 49, and automatically opens and closes the electronic shutter to take an image at a predetermined timing.
The CCD camera 46 may be any optical camera, but it is desirable to facilitate the detection of the position of the golf ball 43 using the CCD camera 46 that digitizes and outputs an image.

FIG. 8 shows an example of an image captured by the image capturing device 45.

A control unit 62f for determining the three-dimensional position of the receiver 62b and the Euler angle from the signal sent from the detection circuit 62e is configured.
The controller 62c generates a drive signal that sequentially generates predetermined three types of magnetic fields in the transmitter 62a, and detects a signal output from the receiver 62b.

Further, the controller 62c performs data processing based on the detected signal, and calculates time-series data of the position of the measurement point and its direction.
The position of the measurement point is the three-dimensional position (x _m , y _m , z _m ) of the receiver 62b with the position of the transmitter 62a as a reference position and the three axes X, Y, Z orthogonal to each other as a reference.

The drive circuit 62d outputs the same signal whose frequency and phase are always constant according to the command signal of the control unit 62f, and sequentially excites the three loop coils wound in the three axis directions of the transmitter 62a.
Each loop-shaped coil generates a different magnetic field each time it is excited, and generates independent voltages for the three loop-shaped coils wound around the three axes of the receiver 62b based on this magnetic field. Since this voltage is three independent voltages generated in the three loop coils of the receiver 62b in response to each of the three magnetic fields excited by the three loop coils of the transmitter 62a, a total of nine (3 × 3) voltage is obtained.

The distribution regarding the strength of the generated magnetic field and the direction of the magnetic field is based on the installation position and direction of the transmitter 62a because the transmitter 62a that forms the magnetic field is fixedly installed at a predetermined position.
The control unit 62f obtains data of a three-dimensional position (x _m , y _m , z _m ) and Euler angles (θ _y , θ _p , θ _r ) using the nine voltages sent from the detection circuit 12e. .

Therefore, by using the nine voltages generated in the formed magnetic field, the three-dimensional position (x _m , y _m , z _m ) of the receiver 62b with respect to the reference position and the Euler angles (θ _y , θ with respect to the reference direction). _p , θ _r ) can be obtained.
Data regarding the three-dimensional position (x _m , y _m , z _m ) and the Euler angles (θ _y , θ _p , θ _r ) obtained by the three-dimensional position / direction measuring device 62 are sent to the processing device 64.

The processing device 64 measures the time-series data of the three-dimensional position (x _m , y _m , z _m ) and the Euler angles (θ _y , θ _p , θ _r ) measured by the three-dimensional position / direction measuring device 62. The data is processed to calculate a head speed history, a grip speed history, a vertical head trajectory, a horizontal head trajectory, a dynamic loft angle, a dynamic lie angle, and a face angle.
Specifically, the head speed history is a time series of the center of gravity position of the golf club head when the golf club shaft is not deformed based on the time series data of the three-dimensional position and the Euler angle and the length of the golf club. Data is obtained and obtained from movement of time series data of the center of gravity position of the golf club head. Further, the grip speed history is obtained by obtaining a time-series movement of the grip position from the measured time-series data of the three-dimensional position, and obtaining this movement. Thereby, the head vertical trajectory can be obtained.
The dynamic loft angle can be calculated from the vector in the length direction of the golf club shaft immediately before impact and the loft angle of the golf club used for measurement. Further, the dynamic lie angle can be calculated from a vector in the length direction of the golf club shaft immediately before impact.

And a processing device 82 for calculating a hitting position of the golf ball on the face surface of the golf club head, a head speed at the time of impact of the golf ball, a dynamic loft angle of the golf club head, and the like.
The dynamic loft angle is an angle formed by the face surface and the perpendicular to the ground at the time of impact of the golf ball. The dynamic loft angle measured by this measuring device is a centrifugal force acting on the center of gravity of the golf club head. This value takes into account the moment generated by the force. The dynamic lie angle refers to an angle formed by the golf club shaft and the ground at the time of impact of the golf ball.

The two cameras 72 and 74 are arranged on the front side of the golfer in order to photograph the golf club head before and after the golf ball is launched. The illumination light sources 73 and 75 are attached to the camera and illuminate the golf club head before and after the golf ball is launched.
As such a camera, for example, a high-speed video camera or a high-speed shutter camera that takes images at a time interval of 1/1000 second can be used. As the illumination light sources 73 and 75, for example, a strobe or an infrared projector can be used.

As shown in FIG. 15, the golf club head is provided with at least three measurement markers at different positions in order to measure the behavior of the golf club head.

A measurement marker is attached to the upper end surface of the crown portion in contact with the face surface.
In the case of an iron-based golf club head, as shown in FIG. 15A, the three measurement markers are attached to the hosel so as not to be in a straight line. In the case of a wood-based golf club head, in order to increase the measurement accuracy, as shown in FIG. 15B, the measurement marker is attached so as to be positioned at the apex of the equilateral triangle. Is desirable.

Since the measurement marker recognizes the measurement marker in an image photographed by the camera, it has retroreflectivity that reflects the illumination light of the illumination light source.
The measurement marker consists of a small number of high-refractive glass beads that act as a lens as a reflector, and are uniformly placed in the ink. The incident light is refracted through the glass body and focused on a single point. , And return to the original light source direction after passing through the glass body again.
Therefore, since the measurement marker having retroreflectivity reflects toward the light source regardless of the angle from which light enters, the behavior of the marker can be continuously photographed with a camera.

  The three-dimensional data calculation means 86 extracts the position of the measurement marker in the three-dimensional coordinates using the position coordinates of the measurement marker in the image taken at different times using the cameras 72 and 74 at the same time. That is, since the imaging directions of the cameras 72 and 74 are known, the positions of the measurement markers in the three-dimensional coordinates are extracted based on the information of the two-dimensional coordinates in the images captured by these cameras.

FIG. 16 shows a time history of a measurement marker obtained by photographing an iron golf club provided with a measurement marker as shown in FIG. The time histories of the measurement markers are expressed with the predetermined position as the origin, the launch direction of the golf ball as the X direction, the direction orthogonal to this, the direction parallel to the ground as the Y direction, and the direction perpendicular to the ground as the Z direction. Expressed in the XYZ coordinate system.
Three plot groups M ₁ , M ₂ , to M ₁₀ indicate positions of three measurement markers taken at an interval of 1/1000 second.

Further, the three-dimensional data calculation means 86 is configured so that the point corresponding to the measurement marker on the three-dimensional shape model of the golf club head created in advance matches the position coordinate of the extracted measurement marker. The position and orientation of the golf club head are calculated by arranging the shape model in a three-dimensional space.
By calculating the position and orientation of the golf club head in the three-dimensional space with the passage of time, the three-dimensional data calculating means 86 calculates time-series data of the position and orientation of the golf club head.

FIG. 17 shows an example of a three-dimensional shape model that is a simplified reproduction of the iron-based golf club head shown in FIG. FIG. 17 shows a corresponding point m corresponding to the position of the measurement marker.

That is, by arranging the three-dimensional shape model shown in FIG. 17 according to the time history of the measurement marker shown in FIG. 16, the time history of the three-dimensional shape model can be expressed.
Thus, the time series data of the position and orientation of the golf club head can be calculated using the time history of the measurement marker and the three-dimensional shape model.

  The analysis means 88 uses the time series data of the position and orientation of the golf club head, and the hit position of the golf ball on the face surface of the golf club head, the head speed when hitting the golf ball, the trajectory (up and down and Left and right), the dynamic loft angle and the dynamic lie angle of the golf club head are calculated.

As shown in FIG. 16, using a three-dimensional model that reproduces a golf club, the position and orientation immediately before launching the golf ball are grasped, and the golf ball hitting position on the hitting surface of the golf club head is determined based on these positions. calculate.
The hit point position on the face surface can be displayed in a two-dimensional coordinate system based on the center of the face surface. For example, when the hit point position is 4 mm on the heel side and 6 mm on the crown side from the center of the face surface, the hit point position is expressed as (6, 4).

The head speed at impact can be calculated from the shooting interval of the camera and the amount of movement of the three-dimensional model.
The golf club head trajectory, dynamic loft angle, dynamic lie angle, and face angle can be calculated using a three-dimensional shape model reproducing a golf club as shown in FIG.
